iOS 6 iPhone 4s battery drain

Did an OTA update to iOS 6, and my iPhone 4s is draining quite quickly almost a percent every three minutes


Only apps running are Settings, Messages, Phone, and Mail, and Location Servces are on for Google, Maps, Nearby, Reminders, Safari, Siri, weather, and YP Mobile (sames as before the iOS 6 update) All apps are up to date, and restarted the phone twice. On local WiFi, with AT&T cellular service, four bars.


Phone would get warm at times as well.


Maybe it's an anomaly, else, lets see if this post grows...

Sounds like a classic case that you need to calibrate your battery. Let it run until it totally cuts itself off (spinning star) Then charge it for at least 1.5 hrs past when it shows 100% unattended. Dont stop when it shows 100% its not finished yet. iPhone has 3 stages of charging and it takes a bit after it shows 100% to complete.

Thanks for your suggestions! But now I can't even try them because my iphone won't charge at all anymore. This morning it was at 1% battery again when I woke up and I decided to try resetting it, but it took me to the battery screen. So it's been charging for the last 3 hours and it still just shows the big battery symbol with a sliver of red and a the lightning bolt symbol underneath. I've tried to force it into recovery mode but it will not budge. I have no idea what to do at this point 😟


Would I be able to calibrate it from the battery screen that it's on now? If I just unplug it and leave it, will it eventually just die?

There are several options. I assume you are using exchange email and its set up for push? There is a known issue with exchange activesync getting hung sometimes. Remove the email account,reboot the device and add it back typically will solve it. Some have better results with exchange set to push but others work better with fetch. Manual is most likely the best for battery saving because it only checks when you open the mail app. Thats fine in a lot of cases because if you are not going to actually read the main the instant it comes in there is no point in the phone constantly checking for new email. However in that case you wont be notified that you have new mail.

My company did an e-mail change over the weekend and although I am receiving e-mails fine, I can't keep the battery charged and the phone is heating up quite a bit.


I'm currently running on iOS 6.1.


Help!!!!


So some things to try after you do remove it if that doesnt help. Set it to push if you are set to fetch currently or vice versa. Set to manual if you dont care to be notified for each email that arrives.

Just wanted to say, after the most recent update, my phone was dying so quickly, in complete standby (diabled EVERYTHING for testing purposes). Never considered the mail thing. Just changed my mail from push to fetch and instantly noticed a result!! So maybe exchange is the culprit...I don't have any idea. This does seem to have helped and I am going to leave it like that and see. So thanks guys!! You all rock!

The problem with Exchange is not on the server side. It is on the APPLE side of the house. Here is what I have done, so far, to try and isolate / solve this problem.


1) Removed ALL Exchange accounts on my phone (4S), including Gmail.

2) Let the phone sit and battery drain.

3) Added back my company Exchange account...settings are FETCH @ 15 minute intervals.


Within 5 minutes, my phone was back to overheating and draining battery life faster than a sailor can drink beer!


Apple is sitting silently by...losing my respect. I have MAJOR SWAY on what happens in my company. If I dump my iPhone, there will be at least 20 other people follow me. Additionally, my family has four additional iPhones.


And I will make a BIG racket on the internet!


So...Apple...step up to the plate and get this problem resolved! Your customers shouldn't have to put up with this kind of crap!

Is this good for an Ipod Touch 4th generation:

65%,Usage: 4Hours,57Minutes,Standby: 1Day,1Hour


Is that good?

There's no way for a stranger to easily answer this question. It all depends on the amount of resources the apps consumed during usage. Example: streaming music or video, playing games, or using GPS will consume far more energy (battery) than simply talking on the phone or text messaging. Also a cellular connection verses a Wi-Fi connection will lead to a difference in battery life.


It sound good theoretically, but only you can determin if 65% is good or not. Ask yourself if this usage was normal for you or was it higher or lower than your average usage? Figure this out for yourself. 🙂


The people here discussing this OP's issue do notice a dramatic difference in battery life because they know what their battery life was like before updating to iOS 6 based off their typical usage patterns and behaviors and remaining battery life with their device(s) using iOS 5.x.
