Q: iPhone 4s Battery Life?

For me the battery would be okay, if the usage would be the actual usage and not some phantom time.

Who is using my iPhone for 6 hours while I am asleep??

Over night there's a 35 % battery drain. Why is that?

And has anybody with a usage almost being like the standby time resolved the issue? Or is it a hardware defect?

I also got the sim pin problem, so is there a connection?

I agree with you. The battery performance of my 3GS deteriorated when I installed IOS 5.0.  To me, this proves one important thing: this is a software issue, not a hardware issue. 

My daughter installed IOS 5.0 on her iPhone 4, and she has not had battery problems at all.  To me, this proves something else: it is not IOS 5.0, per se, that is the problem.  It is some combination of settings and active apps that is causing the problem, and since there must be millions of possible combinations, it isn't difficult to see how this might have slipped through in testing.

Apple clearly knows this is a problem, and I believe they also know that IOS 5.0.1 did not fix the problem completely.  One poster asked what good the iPhone was if some of the important features are turned off.  I don't think that anybody is claiming that turning off features is a valid solution.  But if any of us find things that may give clues to the Apple developers what is happening, I've got to think it is useful to post that information here.

I had really bad performance yesterday until someone suggested doing a hard reboot (hold lock button and home button at the same time for about 10 seconds until the apple logo shows up.  Ignore the "slide to turn off" because that will not do the hard reboot.).  After the hard reboot I noticed a huge difference in battery performance and am only losing about 1% per hour on standby.  I have push e-mail and even have location services on.

Wow that hardboot actually re-calibrated my battery

What is going on. Updated to iOS 5.0.1. Left my phone on my desk last night at 90% and found it this morning with 7%  !!! (9 hours in between) No useage, no nothing! Apple sort this out. I can't leave the house without a charger in my bag...

Finally did a reset all settings without deleting content and selected set up as new iPhone.  It kept all my media and apps and now battery is better than ever!  Over 30mins without leaving 100%

IMPROVES BATTERY LIFE!

I posted earlier i am seeing better battery life. Also the phantom usage is gone on what i did

I have already erased everything from the phone and started as new did not restore form back up.

This morning I had stats like Usage: 4 hours 45 minutes

Standby: 7 hours 3 minutes

Exchange is on fetch

icloud is on fetch

Hotmail fetch

I decided to play around to see what was using this phantom usage and it results it network settings WIFI/3g

I was on wifi during the night and it was using up the usage so i decided to start

disabling notification centre apps and location services still usage was going on even on fetch email.

Below were 1 hour TESTS!

I switched to airplane mode = usage stopped

switched to 3G = usage stopped

went back to wifi = usage started to occur

So I suggest if people having been getting the phantom usage with wifi to test 3G for about 20 mins then test wifi again to see if you get these results and if some are using 3g and getting this I suggest switch to wifi.

I do not think the problem is lying the notification center/ location center I indeed think it is occurring within the network

settings such as WIFI/3g and apple need to look into this as I cant keep using 3g has i dont have unlimited data and 3g drains more battery.

***BETTER BATTERY LIFE*****

Currently what I am  doing  is using 3G on standby, when i start browsing i switch to wifi and my battery life has gotten a little better but i think wifi is draining battery alot more than it is meant to apple need to look into this.

Also i have IPAD 2 that is starting to get drained i have to charge it everyday where as on IOS 4 i use to get atleast 2 days out of it.

Thanks

Forgive my total ignorance as I bought the iPhone 4S recently and it's my first apple product ever, but what was a 'good' battery life for an iPhone 4 prior to this mess?

I'm still checking mine but it hardly lasts a full day before needing more juice.

When I've upgraded iphone3gs to ios5, battery life was terrible. What has resolved the problem was a factory reset. That could be misunderstood: I don't mean to reset iphone and then restore from backup, I mean reset the. Iphone stop.

I re-configured everything from scratch. Only afterwards, I synced apps, music, photos with itunes.

Has anyone tried this procedure?

I think that resetting and restoring from backup can't change anything to the phone.

If this solves the problem to iphone 3gs and 4, It doesn't fit to the ones buying iphone 4s... Unless people with iphone 4s having the problem had configured the device using existing configurations.

Please provide the following system information:

Device : (Include Ram and APP list if you can) (App list is important.)

Using iCloud:Yes/No

WiFi:Yes/No

WIFI usesage: (Percentage for example 20% of the day) and type of network device. Airport 2010 2&5 gig auto switch, older newer, etc. B/G/N

Siri: On/Off

BlueTooth:On/Off

Mail: Exchange or non-exchange?  Push or fetch, or manual?

Location Services: On/Off?  Other settings under location services > system services?

How you are charging: (Direct Plug or using a computer)

Computer including running OS. (Example Mac Book Pro 2009.)

Calendar:(Google/Exchange/iCloud)

Mail:(Again as above.)

Location Services: On/Off?

iMessager: On/Off?

Brightness:

Other Network apps: Twitter, Facebook, etc.

Network Carrier:AT&T, Verizon, Sprint, etc.

Is the phone or device ever been jailbroken or altered in any way from the original agreement: Yes or No.

Did you have APPLE migrate you data in the APPLE store? Yes or NO

Usually we got 2-3 days in 5 and 5.0.1 seems better, but since I had no problems I did not time it originally. ...As I have stated we have had no problem, our devices go about 2 days using heavy network traffic.

Are you serious? That's actually MUCH better than Apple's specs. Talk time is "only" a max of 8 hours. Video playback and wi-fi internet is 10 hours.

How are you getting TWICE what the specs say you can get? What do you call "heavy usage"?

Your post may give others unrealistic expectations. I drained my battery down to 10% in 16 hours yesterday with heavy usage, and I thought I was doing GREAT. That seems to be in line with the specs.

Please explain your atypical and better-than-spec battery life.

Thank you

Do a Hardreset of you iPhone. Hold down Home and the Powerbutton. Ingnore the Slide to Turn-Off.

I've had two Verizon 4s'. One was a 16gb which I experienced horrible battery life on. My sister decided to use her 2year upgrade on an iPhone and was content on a 16gb, and I decided I wanted to up to the 32gb, so she used her upgrade on a 32gb and I gave her my 16gb and paid the price difference. On the new 32gb, I did NOT experience the horrific battery life. Battery life was pretty good with wifi and bluetooth consistently on, icloud on, siri on, many location services on, etc..... but, after the update to 5.0.1 it ruined the great battery life. Now I'm back to my battery woes that I had with the 16gb 4S that I had. I noticed a 16% battery drop within 45 minutes (might be of note that my phone was trying to search for 3g signal in an area with full coverage).

This tells me that prior to the update there may have been bad batches of phones out there that experienced the issues and some that did not. And also... 5.0.1 made both an iPhone that was not experiencing any problems and one that was, worse in terms of battery life. I wish I could say that it has improved things (or at the least made no difference), but atleast for me and my sister... it has not. What's even more frustrating is that there's no way to even revert back to 5.0... which was working perfectly fine for me. =[

Device: iPhone 4S

iCloud: Yes

Wifi: Yes

Wifi Usage: always connected while at home, even if at times it's just on standby/locked. Home network, basic Thomson wireless router

Siri: On

Bluetooth: off mostly, only turn it on for driving.

Mail: I tried both really. Had it set to manual to see for battery life changes.

Location Serv: on

Charging method: Did both, direct charging mostly

OS: Win7 Ultimate, Dual core cpu (on laptop)

Calendar: all on (never touched actually)

Mail: Got 4 accounts: hotmail, gmail, work (MS exchange) and cloud

iMessage: no, i live in malta and don't know many with iPhones.

brightness: auto-on, slider to full

any apps are open mostly just for usage and then re-closed. Got FB, no twitter

Network: GO (check www.go.com.mt)

Never jailbroken. Received totally new and sealed from UK seller on eBay.

Just joining the discussion here.  My first Apple iPhone...as a Sprint loyalist, I waited for iPhone 4.  I just "upgraded" to iOS 5.0.1 and I'm having battery AND signal issues. Prior to the upgrade, my 4 (not 4S) was perfect, no battery or signal issues.  Subsequently, I just charged the phone overnight (for 8 hrs) and the phone shows 92% capacity.  Will not go over that amount. 

The bigger problem, however, is that instead of the 4 or 5 bars of signal that I'm used to, it won't connect to the Sprint network at random inconvenient time.  During these times, I can't text or make or receive calls.  The only way I've been able to reestablish signal is to turn to airplane mode and then turn it off...it will immediately connect, but only temporarily.  Since last night I've had to do this approximately 12 to 15 times. This is SO unacceptable!!!  Can anyone help me here??
