iPhone 4S 5.0.1 Update Improves Battery w/ Settings Reset

After installing the update make sure you reset all setttings. I have done a few updates now and have had much better sucess after settings reset all. Standby drain has been virtually eliminated from 2-4% hr before update. It is located in settings/reset//reset all settings. You loose some wifi and desktop settings, but data, apps, etc remain intact.

Hey the new iPad just came out, along with the new iOS 5.1 update and it says that it "Addresses bugs affecting battery life" and I hope it works this time, because it didn't work for me with the reset settings.

Well I'll update it tomorrow (its available OTA) (its 11 pm

In switzerland now) and I'll let you know if it works for me


Regards

Updated to 5.1 and my battery seemed to have gotten better at first but I'm not so sure now. I charged it last night to 100% after letting it fully die (meaning phone shut off). Turned on airplane mode and when I woke up it had about 8 hrs standby still at 100%. Turned 3G and wifi on and it stood at 100% for another 2 hrs before going to 99%. So all in all it was on standby for 9 hrs with 30 mins of usage.


But now I am having some overheating issues and my battery has started to drain really really fast. Right now my stats are:


Standby: 16 hrs 39 mins

Usage: 3 hrs 49 mins


Wifi is on and 3G is on.

Hello David,


Months ago, I tried your procedure to improve battery life on my iPhone and it worked very well. Now that 5.1 is out, would appreciate your thoughts. From the last experience, I'm somewhat reluctant to upgrade without confirming that battery life isn't going to be an issue again.


Do you have any thoughts on whether battery life is an issue with 5.1?


Regards

Sanjay

My battery life went down noticeably after I updated to IOS 5.1 also.

Here what worked for me:


After reading other users suggestions in this Thread and others, I decided to do the easiest first.

I went into >Settings >General >Reset >ResetNetwork Settings


I had to reconnect my Wifi but other than that it was simple and so far battery life has improved.

If that had not work I would have tried the Reset All Setting next as mention earlier in this Thread.


As standard practice I always let my battery drain down once to about 10% each month and fully recharge.
