iPhone 4S Battery Life: Best solutions and procedures for 1st time user: 1-Do you have a battery life issue (learn first what the usage time spec is about) 2-What can you try to remedy the situation without reading 500 pages of posts

What follows is a grouping of some of the most fruitful procedures - from what I've seen in the biggest battery life issue thread - and some background information and discussion for solving or improving the battery life with the iPhone 4S and may be applicable also to devices on which iOS 5.0/5.0.1 has been applied. Credit goes to the respective users who contributed this information to the forum and they should be commended for doing so. This is not a final listing. The goal here is to provide a first stop sort of knowledge base document for newcomers instead of having them perusing the never ending threads where the wheel is reinvented on every page...

Please don't post your questions, usage screenshots, or claims that it worked or not for you or anything here except PROCEDURES/DEBUG STEPS/SOLUTIONS or improvements to the procedures already listed here. Try to use point form and to be as concise and clear as possible. Hope all this helps.

Thank you and good luck!

General info and specs

---------------------------------------------------------------

First, take a look Apple's battery tips, info and specs(obligatory reading for all Iphone 4S users - read it once and for all):

http://www.apple.com/batteries/iphone.html

http://www.apple.com/batteries/

... you didn't read it? loll Always remember this i.e. the definition of "usage":

Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.

I'm still not convinced you read the links so here's what Apple has to say in terms of fine tuning your battery life:

Optimize your settings

Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.

Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.

Usage specs for the 4S - http://www.apple.com/iphone/specs.html:

Talk time: Up to 8 hours (12.5% per hour drain) on 3G, up to 14 hours (7.1% per hour drain) on 2G (GSM)

Standby time: Up to 200 hours (0.5% per hour drain)

Internet use: Up to 6 hours on 3G (16.6% per hour drain), up to 9 hours (11.1% per hour drain) on Wi-Fi

Video playback: Up to 10 hours (10% per hour drain)

Audio playback: Up to 40 hours (2.5% per hour drain)

So a scenario of normal usage could be for example: 4 heavy hours of 3G internet browsing (66.4%), with one hour of call on 3G (12.5%) and 22 hours of standby (11%) = 100%

A battery life issue is a problem where the drain is really out of spec either during usage or standby or both. For example, multi-% per minute drain during usage or a 10% drain per hour during standby is problematic. Browsing the internet on 3G during one hour and losing 16-17% is not.

Apple's test methodology for claiming the specs:

davidch tips (reset+full discharge recharge):

Go through these steps to address the battery after updating to iOS 5.0.1:

1. Reset all settings (settings app-> general-> reset)

2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)

3. Turn off system location services timezone and iAd

4. Fully discharge battery (tilll it shuts off with the spinning wheel)

5. Fully recharge battery (overnight if possible)

In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!

---------------------------------------------------------------

ram130's variant of davidch i.e. additional steps:

Now using davidch original steps and attaching the tweaks I made to get me more usage. As shown on page 29.

Go through these steps to address the battery after updating to iOS 5.0.1:

1. Reset all settings (settings app-> general-> reset)

3. Turn off system location services timezone and iAd

4. Fully discharge battery (till it shuts off with the spinning wheel)

5. Fully recharge battery (overnight if possible)

6. Disable Siri 'Raise To Speak' and REBOOT *( if possible use another camera to verify the infrared is off after the reboot).

7. Set emails, icloud and calendars to fetch. ** test. Mines on hourly.

8. If your in a no signal and your phone is saying "Searching..." even after 10mins, reboot while in that area and after 1-2min it should say "No Service". This mainly applies to Verizon customers and improve battery life in these areas.

9. *optional* Goto Settings > General > Network and you will see "Hotspot.." loading something, wait a few seconds and it should say "setup personal hotspot" then exit out.

* I notice a great improvement after disabling this and rebooting. This increased my "screen on" usage or at least helped it. Make the change.

** I have not tested push yet to narrow down the drain but I had this change on my phone. I believe exchange push is responsible for some stand by drain. As for icloud, haven't notice much of a difference. Just try it for a day. My email still came in fast most times. Again still testing, will report back on these..

buxbuster tips(wifi sync, iCloud):

These are my own tested workarounds that worked for my iPhone 4S and seemed to have worked for others as well :

Workaround number 1. Deselect wifi-sync in iTunes and press sync.

If that doesn't work try :

Workaround number 2 : Remove iCloud, reset network settings. ( I guess this won't work for you since you don't have it enabled ).

If both workarounds fail, you can always try to completely wipe your phone. That also solved some of the cases out there.

---------------------------------------------------------------

rolandomerida tips - i.e. buxbuster and additional steps:

Finally, I solved the syncing error loop. My contacts are syncing flawessly again between my devices and iCloud, and yes, the battery stopped draining, which is the main topic here.

I followed instructions from buxbuster (check his workaround a few pages up!) and an additional BIG step to restore contacts and syncing, as seen in a MacRumors forum.

This is what I did:

1. Make a backup of your Address Book, using the vCard option (or both, it doesn't hurt). Save it for later.

2. In your iPhone, delete iCloud account. When it asks, accept both: delete AND delete from my iPhone.

3. Reset network settings. The iPhone will restart, then will ask you to unlock the SIM card.

4.Turn Wi-Fi on.

5. Add the iCloud account again.

That's for Buxbuster's workaround. For some, it might work just like that. My iPhone repopulated from iCloud after step 5, but I still had that "server error" on iCloud. I had to do some extra steps, since my Mac was not syncing to iCloud and couldn't edit anything on my Mac or iCloud. Syncing back had to be fixed, too. If not, the syncing loop would continue from my iPhone, and the battery would drain awfully again.

1. In System Preferences -> iCloud, I turned Contacts off. I chose "keep on My Mac" those contacts, but I got an empty Address Book after a while. And a few minutes later, iCloud contacts were empty and my iPhone also. It is scary at first! Now, before importing that vCard backup...

2. Turn Wi-Fi off. This is important, since your contact-empty iCloud will attempt to wipe your Address Book from your Mac in seconds after importing.

3. Import your vCard backup to Address Book. Just drag it to your blank Address Book window; it asks if you want to import "x" number of cards. Of course, say yes.

4. Turn Wi-Fi on, and then iCloud contacts on again (System Preferences -> iCloud). It will offer to merge your newly populated Address Book with iCloud (which is empty at this point). It should upload every single contact to iCloud, and then to your iDevices. If not, a fifth step would be to import the vCard file to iCloud, but it shouldn't be necessary.

So, with iCloud syncing working correctly, there is no battery draining! Again, that was my particular issue.

I can't tell if this is the single answer to the widely spread battery draining problem, but it sure can be fixed with these workarounds, and yes, Apple should address the problem with a future update, for we affected customers don't need workarounds in the first place

This is the MacRumors discussion:

And dont' forget to check buxbuster's fix, video, and THANK him!

Miless tips (full 800mb release of 5.0.1 and sanitizing a restore):

As for 4S battery life. Try doing this,

1. Settings>Location Service ... disable all location services you do not need. In particularly Facebook because it drains the battery a lot.

Scroll down to the bottom at Settings>Location services>System Services ... Disable Setting Time zone, location based iAds, Diagnostic & Usage.

2. Settings>Notification>Calendar ... turn off the Notification Centre.

3. Settings>General>Reset ... do Reset All Settings. Doing this will not wipe out your iPhone. It will just Reset the network settings, location warning, keyboard dictionary, etc... but it will clear up some corrupted data there. Generally this will help.

Try these 3 steps first... if it still drains a lot, try the following,

4. Drain your battery down to 1%. Then charge it up using USB from PC ... not the charger. The charger output 1.0 A ( x 5V from USB ... you get 5W power). From PC, output is only 0.5A x 5V = 2.5W power. Charging is slower but trickle charge 4S helps the battery retain its charge better. I think it takes about 3-3.5 hours to charge full from USB/PC compared to slightly below 2 hours using iPhone charger.

If after doing the above still could not solve your battery issues (mine with iOS 5.0 was ok up to step 4, but not iOS 5.0.1).... plug you iPhone to a charger (any charger), from iPhone, access your iCloud ... set it up if you havent. Back up your iPhone data to iCloud. if you do not have enough storage (only 5GB is free), go to details and select the apps you need its data backup, choose only those you really need and leave those unnecessary ones out. Back up your camera roll to your PC/Mac manually as it could be too big to backup to iCloud.... once you have it setup, make sure you are on Wifi ... tap backup to iCloud from your iPhone. It will take a while if the file is huge.

Once backup to iCloud is completed, plug your iPhone to PC/Mac and launch iTunes 10.5.1 (make sure you have 10.5.1)

Click Restore. It will automatically initiate a download of iOS 5.0.1 ipsw for iPhone 4S. Wait for the whole process to finish, ie. download, restore software/firmware.

Once its done, do not set up your iPhone from iTunes. Set it up on your iPhone. Go through the selection. When prompted, select restore from iCloud (from your iphone backup earlier). Keep your iphone plugged into iTunes while restoring backup from iCloud. Because while restoring from iClouds, some data will be synced from iTunes if you plug in, e.g. music, video, etc... unless you bought these content from iTunes store. Apps will be downloaded from App Store from the cloud.

Once it's all done restored. Turn off your iPhone,.. and turn it on again.

Now, hopefully your battery wont be draining so fast anymore. Usually it wont after this. But you need to charge your battery at least 4-5 cycles to stabilize the charge on the battery. I dont know why... but battery life seems to get better and better for me after a few charge cycles after all the above work.

Good luck. Let us know if it works for you.

---------------------------------------------------------------

W. Raider tips (Sirii):

Bottom line for me of things that helped battery life are:

1. Turing off Siri and Rebooting the phone by holding the Home button and Top button down, ignoring the slider, until the phone shut down. (turn off Siri, reboot, and check top front of iPhone 4S against a lesser camera like the front-facing camera on an iPad2 - making sure the IR sensor is off)

2. Fully draining the battery, meaning using the phone until it shuts itself off from a drained battery and then recharging it to 100% about 4, maybe 5 times. I charged it both with a Mac and a wall charger.

Hope this is helpful!

Comments

jmm514 remarks (Twitter):

I may have found something. I had Twitter disabled in my notifications, but got a tweet today that popped up on my home screen. Didn't know I had this enabled. At the bottom of the Twitter notification settings is the home scrren toggle. Since disabling this, battery life seems better. Considering there is no setting for frequency of checking for tweets, it appears the phone is continually connecting to wifi to check for new tweets.

tmksnyder comments (notifications, corrupt data in iCloud):

For me, I found my iphone on wifi mysteriously connecting to my mac. I eventually narrowed it down to the Apple Move Trailers app which keeps a file in iCloud. The phone was trying to sync the file with the mac in the background even when the Movie Trailers app was closed (hitting the red x). Based on my macosx logs the iCloud process that was trying to sync was working directly between the phone and the mac without using itunes by connecting to an https address hosted on the phone. It was connecting every 3 minutes and failing (while phone was awake or awake during during a notification). I also found that iCloud control panel on OSX would error if I tried to delete the file. I fixed it by removing the App and doing a hard reset which stopped the sync. I probably could have turned off iCloud document sync in the phone but didn't think of that. My battery life has greatly improved while at home on wifi. I am now at 28 hrs standby, 2 hrs 20 minutes of usage, and 68% battery. It was ok before where I could get 20-30 hrs standby and 6 -8 hrs usage. My usage today was phone calls, 3g surfing, and music via bluetooth in the car.

I also found even with Itunes iMatch, if I mass updated tages, art work etc, it would hit the phone on wifi even in standby. I was amazed. Granted if I am not doing updates, Match won't hot the phone so this was a once in awhile event. I could drop my percentage by 5-10% in a matter of minutes when doing updates. I think a lot of our problems are background processes, associated with iCloud, notification, and apps. More features means more battery. I think the key thing is to keep track of what has recently been added or changed if battery life gets worse all of a sudden. It may be an app that was recently installed and if possible you may want to completely remove it and not just quit it.

[...]

With twitter, i think it uses push notifications so it doesn't need to be running and actively poll on the phone. For instance , if i quit the mail app, i still will get mail notifications and can swipe the message and load mail. Apple Push Notifications servics maintain the connection to the phone and there are likely pings or connection checks that occur for the service on an os level not an app level. This minimizes the load so there arent a bunch of apps all runing and constantly checking. The notification service , if it is contacted from twitter or another service with data, will check the settings you have registered to the with the apple push service and send the notification to your phone. No matter what, there is a drain with notifications. M hunch is once one application is configured to receive notifications, connection checking occurs betwen the push service and the phone so it knows where it is on the network. If it is implemented correctly, these checks arent frequent if you are still and more frequent as you move. The other drain is for when the noification hits and is processsed. If i get 9 emails over night, my screen just popped up for 20 seconds or so to process each message using battery. I would even think that just go from low power to turning n the screen uses more juice than if the device was already on and i get the message. On nights I get no notifications, I see a 3 or 4 percent drop. On nights with a number of notifications, i have seen up to a 10 percent drop. Besides notifications, wifi sync and icloud will poll on the local network and use up battery if the host computer is on and running itunes or trying to sync a data file that is corrupt (which i had with the apple movie trailers app causing my phone to drain). For me turning off wifi sync and remving a corrupt file in icloud solved my battery issues and I get over 24 hrs of standby with 6 to 9 hrs of use and this is with all the normal location services and push serivices turned on.

See http://developer.apple.com/library/mac/ipad/#documentation/NetworkingInternet/Co nceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html for more info. I think it has a good overview of how the notifications work.

Happy holidays my ***!

Jan 6, 2012 2:25 PM in response to iPhoneTatu

Be polite or get lost. No one said you should do all these things. This is just for reference. Take it or leave it. If you're not happy, get support, an exchange or refund or whatever, but don't take it out on me.

Thanks.

Jan 6, 2012 2:58 PM in response to 1AppleADayNoWay

Just upgraded from iphone 3 to 4s. I was doing well, and suddenly, after turning on bluetooth to access my headsets, I noticed definite change in battery life. I just turned bluetooth off, as well as push notifications and location services and battery seems to be happier. I'll check back in if it is not resolved.

The ambient light sensor brightens the display when using the iPhone in brightly lit environments, and dims the display in low light. To test this sensor, do the following:

If the iPhone is in a protective case, remove it from the case. If there is a protective film on the display, remove the film.
Verify that the Auto-Brightness setting (Settings > Brightness) is set to ON, and that the Brightness level is set near the middle of the slider.
Press the Home button to return to the Home screen and then press the Sleep/Wake button to lock the iPhone.
In a bright environment, cover the top third of the iPhone to block the light, then press the Sleep/Wake button or the Home button to wake the phone. Slide the slider to unlock the phone.
Notice the brightness of the screen and application icons; they should be somewhat dimmed.
Remove the cover from the top of the display and in a few moments the display should get brighter.

Display shows a white screen

Try turning iPhone off and then on again.
If the iPhone will not turn off,try to reset it. Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until either the Apple logo or battery symbol appears. If the battery symbol appears, continue to charge iPhone until it is fully charged.
If that doesn't work, try restoring the device.

After finishing a call the display remains black

If the iPhone is in a protective case, remove it from the case.
If there is a protective or antiglare film on the display, remove the film.
Clean the screen, especially around the receiver, with a soft, slightly damp, lint-free cloth.
Try turning iPhone off and then on again.

Screen will not lock or go black when answering calls

Verify mute or speaker have not been activated, just prior to placing your ear over the receiver.
While holding your hand over the top third of the display, verify that the screen is locked or goes to sleep.
Try turning iPhone off and then on again.

General phone use

Call and connection issues

First, see the iPhone Call and Connection Assistant for troubleshooting steps.

No cell signal strength anywhere

If your iPhone is in a case, ensure that it isn't causing interference.
Contact your carrier to verify that you're in an area with network coverage.
If your iPhone has a SIM card, verify that the SIM card has been activated with iTunes:
1. Download and install the latest version of iTunes.
2. Connect iPhone to a USB 2.0 port on your Mac or PC (not on the keyboard) using the dock or cable. iTunes opens automatically.
3. Follow the onscreen instructions in iTunes to activate iPhone and sync your contacts, calendars, music, photos, podcasts, videos, email accounts, and web bookmarks.
If you are using the iPhone on a CDMA network, ensure that your Preferred Roaming List is updated. Contact your carrier for assistance.
Try to restore your iPhone

Note: Your iPhone may be able to receive calls in as little as 15 minutes after activation. If you are migrating your current phone number, it can take longer–up to several days, depending on the type and status of your former service account–before calls are routed to iPhone. In the meantime, you can make calls and use the device's other features.

Intermittent service in an area with good coverage

If iPhone is in a carrying case, try using it without the carrying case.
Try turning iPhone off and then on again.
Try moving to another location.
If service is still intermittent and your iPhone has a SIM card, contact your carrier or visit your local Apple Retail Store to see if the SIM should be replaced.
If you are using iPhone on a CDMA network, update the Preferred Roaming List (PRL). Contact your carrier for assistance.

Additional Information

Avoiding hearing damage

Permanent hearing loss may occur if the receiver, earbuds, headphones, speakerphone, or earpieces are used at high volume. Set the volume to a safe level. You can adapt over time to a higher volume of sound that may sound normal but can be damaging to your hearing. If you experience ringing in your ears or muffled speech, stop listening and have your hearing checked. The louder the volume, the less time is required before your hearing could be affected. Hearing experts suggest that to protect your hearing:

Limit the amount of time you use the receiver, earbuds, headphones, speakerphone, or earpieces at high volume.
Avoid turning up the volume to block out noisy surroundings.
Turn the volume down if you can't hear people speaking near you.

For information about how to set a maximum volume limit on iPhone, see the iPhone User's Guide.

Do not open iPhone

Never attempt to repair or modify iPhone yourself. Disassembling iPhone, including the removal of external screws, may cause damage that is not covered under the warranty. iPhone does not contain any user-serviceable parts, except for the SIM tray and SIM card on GSM models. Service should only be provided by an authorized service provider.

For more information about repairing or modifying iPhone, see the product information and safety guide for your iPhone.

In my final post for the foreseable future (yeah, I've said that before), I've decided to extract comments made by "Sticktron" from the "5.0.1 update--even worst battery life" and "iPhone 4S battery life" (aka the "big" one) around Nov 17 2011. The reason for doing that is that this guy is basically the only dev I saw shedding some light on the "issue", plus his style is quite entertaining. It also remind us that nothing is ever clear cut in this world and that often issues arise out of a balancing act more so than from a black or white "bug" context. Of course, I personally believe there might be with iOS 5+4S a series of issues which vary in degree of importance, from ignorance of the specifications to hyped marketing and poor support tools to some limited hardware issues, badly developed apps in the store and carrier side considerations. It is unclear which issues have been fixed at this point and if Apple can ever deliver fully on the device for every user considering all usage scenarios in the user base and the sync ecosystem etc. Most likely we'll never know. Anyways, here goes Sticktron's tale, as one could put it:

200 replies since I posted the exact problem and temp solution,

And people are Still posting tht their phone is faulty?

Nobody read anymore?

It is not a Hardware, not a Software problem,

It's a service problem.

iOS 5 makes Much heavier use of radios, thanks to great innovations like iCloud,

However, it's NEW, and Apple is still working out real world 100million user type testing,

They can't do that in the Lab, too many strange humans with strange use patterns.

For now, you can fix the drain by disabling features (you don't use) that use the radios too much.

iCloud Backup, certain unneeded Location services, etc.

Honestly, there is No Need for further discussion.

This case has been solved, now we wait for 5.0.2 (maybe next week, soon).

PRoTip: No Genius works at a Retail store, that's for everyone else 😉

[...]

Also, I graphed the Battery drain rate before and after I toggled each feature.

The OS thinks it has Way more juice than it does, because the estimations aren't able to estimate well enough your web service usage.

This is a sketch of said drawing...

http://t.co/TBccNYMz

As you can see, with everything on, a 283hour difference.

With iCloud and some Location services off,

I went on to use the 4S for another 80 minutes of medium use, only 20% drain.

_________________________________________________________

On the Nature of the Constantly Draining Battery in iOS 5 & iOS 5.0.1

There is a bug in <snipped> causing the daemon for AirTraffic to inadvertantly fail to release an assertion check (checking re: AirTraffic connection), thereby not allowing the radios to turn off, thus the quickly draining my battery.

Please fix this ASAP.

Note: Fixing it myself gave me 10 hours of use throughout the day today, working (I haven't been to my desk all day--yay for iOS)

[...]

Seriously?

Apple is ALL ABOUT making electronics as easy as ****.

That's Apple's Prime Directive, their <raison d'etre> so to speak.

You forget that a Computer that works perfectly for everyone is IMPOSSIBLE.

At least given our current understanding of the Universe.

There are literally BILLIONS and BILLIONS AND BILLIONS

of little electronic messages being communicated over an intricate network

of pathways SO TINY that a Lab has to be built

SO SPECIALIZED that there are only like 3 in the world.

And that's just for one component out of thousands 😉

Hi guys,

I posted this in the other big threads,mi hope we all chill a bit.

The 4S battery (all our batteries) are best in class. This is Not a battery problem. It's a logistical problem.

iOS 5 has crazy exciting new features (iCloud, iTunes sync, Siri, etc.) but these all take radio power, which is the most draining of all the iPhone parts, including the display.

For a reference, LocationServices, using assisted-GPS, requires that your Cell, WiFi, and GPS radios all work together to provide you with the most accurate results possible inAny condition. GPS uses AS MUCH juice as playing a 3D game.

So, in Summary...

There is nothing to gain by stalking these forums (and filling my inbox with hundreds of emails a day).

Apple just needs a bit of time to work out a more efficient Balance between web services and Physical limitations of the Universe.

We are pushing unknown territory here, forefront and all that...

[...]

Oops forgot the best part....

Since I first confirmed the source of the issue (on Sunday), my 4S has been keeping pace with my iPad, othe iPhone, etc.

Turn off one or two constant radio users, for now, until next week when Apple tries to address this themselves with 5.0.2

[...]

PS just be happy you hav Apple products, and not an Android, they're obsolete the moment the come out tha box,

Users Just Don't Get Updates. Blame the carriers, thank Apple for having the balls to say "**** you, well just build a nationwide WiFi network, cut you out, Jobs rolled like that 😉

[...]

It's not negotiable.

That's the plain truth.

You can confirm it for yourself.

I wrote a quick graph of drain rate, toggled the features, watched the Rate change by a factor of Ten.

Examine your logs, watchvAirTraffic, it holds an assertion that a connection must be intact. atc checks this once a minute. My logs were being FILLED with thousands of debug messages from atc. Turn off iCloud, iTunes synce, temporarily, you can Readvalong as the OS lifts the assertion and the connections are allowed to close.

[...]

I use my 4S all day. I Dev on it. Make jailbreak tweaks, store Apps, I hack, I research, YouTube, drop dope rhymes on twitter, all day long. And it doesn't die.

You came here for an answer,mi gave you the answer. P,ease wait, there is NOTHING wrong with your phone.

[...]

No, we use advanced tools to build profiles of tons of use cases, measure their drain rate, then maths tell you all that info.

It can be done in minutes. However, you cannotvSimply test for what random people do with such a complex and varied system. You do need some time in the wild. You won't have to wait long, and your battery usage can be lowered for now, you probably won't miss it.

Go read page one of the doc on ios multitasking policy,

Come back,

Apologize.

No joke.

ProTip: iOS (has always) only "run" one App at-a-time,

That's why it's sooo bloody efficient. It's a one-window system.

That thing Tha pops up when you double-tap Home is ***NOT*** windows task manager.

It's a list of Apps you were RECENTLY using....

They now live in a country called InActive RAMia,

Where there is only a trickle of electricity (thank you mDRAM),

Where they Wait to be Summoned back to Please their Masters.

The population of InActive RAMia is easily queried by any number of free Apps,

The Country is nice, don't get me wrong, but when you are living there, you can be evicted at Any Time (killed even),

whenever a citizen of the vastly superior kingdom of Active RAMasia requests more land,

Citizens of poor I.R. get murked

tl;dr

id iOS = one-App- / one-Window- at-a-time Design;

iOS += convenient way to get back to recent windows // (that *were* running) ((App Switcher))

iOS just got too ******* confusing for 99.999% of people to understand,

Trust a pro, listen,

wait for apples rebalancing of cloud service fetch timing.

5.0.2 is in beta on my phone.

It's coming out next week.

Congratulations all Readers, Comprehenders, and Those who took a half hour to fin the answers

Posted waaaaaau back on Sunday, many times, I tries

To help, but people here seem to want to self diagnose an disxuss and rumurate,

This "Community" has proven obsolete this week,

Apple has to implement a Developer Avatat/Badge, and top post voted posts.

For this who missed my 8 posts, funny stories about RAMasia and Divine Assertions,

diagnosis, screenshots... It's all here, in all the big threads.

Took 10 minutes to isolated that the issue was not an issue,

But a Logistical Physical one.

Fixed amount of juice vs 10-to-infinity potential Radio asserters,

Look through Settings,

Turn off Purple Arrrows because they are on

Turn of network-based services.

// get a baseline using a free App

Turn on hat you actually use.

// I dont use iAD tracking, nor should anyone.

// I don't NEED iCloud to sync 3gb of media tonight while I sleep,

I don't NEED those pics on my desktop anyway.

BOOM,

result

GPS really uses cell & wifi as well, for eg.

Your iPhone reports that GPS uses equivalent to A5 power,

Which is 100x more than not.

My battery rocks all day, I use it as my PC all day,

I hack that ***,

And she loves me. Nothing crashes ever, except #ReallyBadApps

I always have >320 MB of available RAM (when not in an App).

Shut **** Down, I jus broke it down,

Only one app is running, ever.

That is NOT Windows Task Manager, you are reading it wrong.

And,

Check me out I'm legit.

Also I used Twitter to directly message Smule,

Letting them know that Magic Piano was somehow holding open a LocationServices connection,

Before you even RAN it!

That's the Worst and sloppiest and most irresponisible and unprofessional and lacking any effort at QA.

I'm starting to believe the 4S is just a bigger battery hog than the 4 was. I've used my iPhone 4 into the ground before it met pavement, but it does make sense - the A5 is a dual-core processor with greater battery demands than the A4 and given that the battery capacity is identical across both devices, there is nothing more you can do short of getting an extended battery case to make the 4S have good battery life. I use Siri, I use location services, I use the heck out of push notifications and e-mail.

Is this an incorrect assumption? I lose 1% battery life every 2-3 minutes when I play an intensive game. Gets worse if it's an online game.

Feb 20, 2012 9:17 PM in response to themystx2

I've tried everything I've have

2 iPhones 4s. I know 4 others. Everyone here.

It just plain *****. I have to plug it in 1/2 into day.

It is the battery drain. I hate this iPhone

My other family members stayed with

iPhone 4. I'm going to give it away to my son

If he will take it. I'm going to go Samsung galaxy 4lte

With the 80.00 case that doubles the battery life.

3S will have 1280x720 4.5 larger screen.

Ice cream. Way better then iPhone if you like games or YouTube

I've had nothing but apple since 1990.

All the iPhones. Everything apple. No more reading resets stories

Setting auto bright. No more discussing this cause I've been around a long time.

I'm sick and tired of the lies here about solutions.

Lies about "my 4s has great battery life"

Lies! By the time I get down typing this I lost 8%

About 8 mins. I'm watching Alcatraz!

This BS Apple pulled on us with 4s

Battery blows. I'm going Samsung!

I think I found the answer to the baterry drain. I been testing setting y setting to see whats causing the poor battery of my iPhones. I been testing my iPhone for a week now and two days ago I turn off the cel network search settings under Location Services and my battery was able to hold for a full day and a half and 7 h off heavy usage (email, texting, phone calls, Facebook, twitter). The main thing was that under standby there was almost no battery drain. I think that this setting was causing my phone to die by 5 pm every day. (I start my day at 6am). Now I'm able to last until the next day with out charging it!

This is what I did a week ago

1. reset the phone to factory settings with the computer ( I had to download the iOS since I did the last update via OTA)

2. Setup 2 exchange accounts with PUSH, and iCloud with PUSH, iTunes match

3. Turn off ping

4. Turn off all system service in location services, exept compass calibration ( I use it with waze).

5. My apps locations services I left on the ones I know I use

Let me know how it goes!

I agree and over the past three months have also done much of the exhausting troubleshooting offered here on my iphone 5s and I have to ask myself, why am I paying to do all this work? In the forum TOS it seems you may be compensated in some fashion from Apple for spending time here so I can see the motive for that. I appreciate these types of electronics are difficult to make perfect right out of the box but if this were my product and I saw my consumer going through all of this I'd have to step in and offer instructions to expedite an immediate solution or refund them if they desired. Making constant trips to the noisy store, waiting in a long que is even more draining than sitting here dismayed. Waiting on the phone in que for a tech, mailing back a potentially defect phone.. ugh! Perhaps this could be construed as a rant? I feel as though our technical troubleshooting is long past our capability and Apple and our Carriers need to weigh in although the TOS tells me they don't do that. So what do we do to get a product that does what it promised?
