Guys... Guys ..... Take it easy ......
I'm still on iOS 6 4s ( expecting 5 soon that's why I've been following this forum since th 23rd September ). My 4s has been draining battery wayyyyyyy more than before the iOS 6 ( updated on 20th September ). It's been a week now since its battery is back the way it was.
Please go back as of page 8 of this thread and look for posts by Griffin800 and Jeremy Roberts ( thank you both for the valuable tips ).. A direct cause for my 4s battery back to normal.
Much more help has been offered in this thread Jeff2006makeuniqe a few pages back, when he posted a part of the iPhone manual concerning battery life. Please Excuse me for reposting, but its quite valuable.
Jeff2006makeunique posted the following ( part of the post, not all of it ) :
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.
End of part of the post ( thanks Jeff2006makeunique ).
I would also like to add the following ( PROVEN WELL FOR MY 4S and the 3 other iPhone 4 and 2 iPads )
Go to Settings > Mail, Contacts, Calendars > Fetch New Data, and set to Manually.
Then swipe down to Advanced and set the iCloud and mail to Manual..
Don't worry now you can recieve your updated mail when you tap Mail icon in home screen.
I've been iPhone addict for 3 years now and I'll never consider any other brand.
The above mentioned REALLY helped in my 4s battery back to normal ( may be even better ).
I hope this would be helpful and I apologize if its a long one.
Regards to all.
Less Apple kool-aid Shahd.....
If my 3GS, 4, and 4s had better battery life with all mail apps set to push, all notifications 'on'......there's a serious problem with my 5 or iOS 6. Period.
I don't want a phone that has to have all the features non functional to make it function past 18 hours of battery life....even if it does have an apple logo on it.
There's no arguing against that Andy - 22%/hour is completely off scale. But didn't you try more than one phone and did they all not have similar battery profiles? That seems like such a low probability occurence that it makes me wonder if there is some other, so far undiscovered, problem. But you did resolve that by deleting icloud so maybe the icloud is corrupted. Perhaps we are all clutching at straws here and in denial of the fact that the iPhone 5 is just crap and not befitting an Apple product. Mine hasnt been too bad so far so I am willing to give it a second chance. After all products based on new technologies are never free of problems but it is a real pity that you have had more than your fair share of them unfortunately. I was in the Apple store this afternoon and got a week extension on the return date so that I can test the phone a little longer. In all this talk about the battery, we haven't considered some of the other problems like the purple haze that appear in some photos taken with the camera. So this phone is sub-optimal to be honest.
Perhaps an alternative would be to rely more on the ipad and use a simpler phone with a longer battery life, For that matter, why do you need a 5 and not just stick with the 4 till the problem is resolved?
Hey I'm sorry Yuniverse, didn't mean to upset you or anyone else. I know you didn't take personally.
It worked for me, so I just wanted to share. So far there are 64797 views to this, if my personal experience helped a few of those, then that's the point.
Sorry if anyone was offended ( cause they tried it all ).
Yep, i'm sure (as i'm a software engineer, so used to debugging stuff) that the problem can be found, minimised and even removed given time. But, i get paid to do that kind of thing, so I can afford only so much charity when debugging my phone. Plus, my wife's phone is connected to the same iCloud account and has no issues, nor did my stolen 4S. But, i agree with u - the signs are that it's likely a corruption somewhere in iCloud data, or a lack of compatibility with the 5. If Apple dive out of their skins to deal with this for me, i'll happily stick around and let them fix it. That i'll be happy with. But, if not and i'm left trying to devise strategys, i'll walk away.
Like u say, this is all because we bought a 5 too early. I've never bought an Apple product so soon after release before, so it's kind of my fault, although i didn't have much choice.
I'll consider a 4, but that costs money too, so that seems like a waste.
I have never been an early adopter myself, this was the first time ever that I bought an iPhone on launch day. Previous years have always been after the phone had bedded itself with users and after any hiccups had been sorted.
Didn't realise your 4S was stolen - I am still holding on to my 4 and haven't even upgrade to iOS 6 and although the battery life is not very good anymore, better the devil you know I say. And it has Google Maps! So I have no problems in returning the 5 if the next few days don't give me a much more sense of comfort with the phone.
Btw, you might be able to pick up a 4 or 4S on Gumtree for a reasonable price. There are many people who have upgraded and looking to sell off their old phones. And then slot in your SIM and wait for that Apple update!
Will keep an eye out for your iCloud update. All the best.
I wasn't going to post here anymore because my iphone5 that was having a problem is now fixed by changing the SIM card. After 24 hours and 1 hour of usage, I am at 88% battery. That seems OK to me. I have three other iphone 5s and they are also fine.
No one should act as if iphone 5s are all bad or IOS 6 is bad because it is factually untrue.
I you want to have the least amount of hastle and fix your problem as fast as possible here is what I would try knowing what I know now after two weeks of fooling around.
1) I would first try airplane mode. If the phone has too much battery drain in airpane mode then I would ask if I could get a new phone.
2) If the phone is good in airplane mode, then I would delete everything reload the software to original condition and not add any apps or sinc it with itunes. I would setup the phone with the bare bones no icloud, no suri, etc. Turn off all notifications, location services, bluetooth, wifi etc. Just leave cellular on. If the phone is bad after this you probably have a bad iphone 5 or SIM card. If everything is ok then add one thing at a time until you identify the offending item. Location services, icloud, specific apps etc.
3) You can also test with wifi on and cellular turned off.
4) If you have exchcanaged the phone serveral times and used the same SIM card and tested the phone with a basic setup then you probably have a bad SIM card.
5) If none of this works then you probably have a problem with the telephone company. If it's even possible, cellular accounts could be bad or you spend alot of time in a strange location. After changing the SIM card and Phone several times this is all that is left. The chances are 1 in a million that the phone or software is bad. So would go to the cell company for help.
You have no idea whether or not iOS 6 is bad or not yourself, no one has established that 'fact'. What we all DO know is....that people visiting this post aren't here for an ice cream social. They are here because their iPhone 5 or other device running iOS 6 has poor battery life...enough so that they are highly unhappy.
You believe you 'solved' your battery issue. Great. I just met someone tonight with an iPhone 5 who thought the phone was in his words 'just excellent!'. I asked I could see his phone settings, he was at 24% battery life with 3 hours and 10 minutes of use with 8 hours of standby.....LOL....ignorance is bliss.
