Since iOS 5.1.1 update the battery drains fast and the phone heats up

Basic troubleshooting steps clearly outlined in the User Guide are restart, reset, restore from backup, restore as new.

If you've gone through ALL the troubleshooting steps and you're still having the problem, then you most likely have a hardware issue and will need to bring your phone to Apple for evaluation.

I'm having the same issue. Phone started to degrade after update to 5.1.1 I have restarted, reset and restored from backup. I haven't tried to restore as new, as I'm not sure what the impact will be in my need to reset my corporate exchange e-mail, etc.

I see from many posts on other boards this is not isolated and is impacting many users. I'm using verizon as a the cell carrier.

My phone is warm and eating battery at a rate of 10% per half an hour in standby mode. No new apps or anything else of that nature.

I am having the same issue

I am having the same problem - the phone is left on the side and a few hours later 10% of the battery has dissapeared (and the phone has not been touched)

Same here. Upgraded to 5.1.1 yesterday evening. Phone was quite warm this morning when taken off of the USB which had never been the case in the 6 months I have owned my 4S. Then the battery depleted very quickly all day. No apps running. Didnt use my phone for anything other than checking the time (sad, I know) all day and after 14 hours of mostly standby the phone hit 20% before powering down. Plugged it into USB and could not turn back on for 5 minutes. In that 5 minutes or so, there was nothing on the screen or any recognition on my computer that my phone was plugged into it.

This *****. Sure hope this is addressed quickly!

Battery on Iphone 4GS worked fine until iOS 5.1.1 update (wireless update), now it drains superfast. 😟 Just a few hours without calling and all apps killed it drains completely empty. Phone is also hotter than usual.

Having the same problem with my Ipad 2 and Iphone 4 after upgrading to 5.1.1. REALLY faster battery drain, hope you have newer update IOS to solve this problem. It's like My Ipad is discharging 1% every 10 mins even in standby mode.

Yup. I should have stayed with ios 5.0.1 really. I have basically done everything you can do, turned off all things, restored network settings / all settings and in the end did a full-reset to see if any apps were bugged and draining battery. Nope, even after full-restore it was bad. But not as bad as some of you, over the night (8+ hours) i still had 100% but when going out and listening to music for 30-min and surfing some on train, it can drain 10%+ which is abnormal. I really wanna go back but since Apple is very restricted when it comes to this and I dont have any old backups I have no choice 😟.

Same here!!! Before upgrading to IOS 5.1.1 my iPhone 4 worked in a great way two days without recharging now battery lasts only 7 hours and even less depending how I use the phone. When I talk on the phone it warms and risk burn my ears! (the same happens when charging). I already reset, restore from back up and as a new but it didn't solve the problem I'm sure it's a problem caused by the new IOS 5.1.1!!!! It's a really big shame for Apple and a torment for us using their products! I'm very disapointed and frustrated even more because Apple doesn't allow us to downgrade to a previous IOS version to solve this! I'm wonder how long we'll have to wait for a new IOS upgrade to fix all of this battery issue and I hope it'll come out soon before ruining completely the battery because the increasing rechargings!

Add the NO WIFI (grayed out) to the issues.

I just bought my new phone last week and they push this out and it ruined my phone !

I am also experiencing the same phenomenon after updating to 5.1.1.....

I also tried restoring twice and it remains hot and battery drain is atrocious....

Does anybody have a rememdy to this already?

HELP!!!!

I have the same problem, switching off push messaging to fetch in email account makes it less worse. Fetch messaging *****, I know, but it's better than having an empty battery all the time.

I originally had the same problem after Upgrading to IOS 5.1.1 from IOS 5.1 as an Upgrade on my Brand New IPhone 4S, but after doing a Reinstall (by clicking Restore in ITunes 10.6.1) without Restoring From Backup, the problem is now gone! I currently have 97% Battery Power Remaining with 20 Minutes of Usage, and 1 Hour and 30 Minutes of Standby Time used up. Just FYI!

I was able to correct my problem!!!!!

Instead of doing what I did twice previously, connected the iP4s to iTunes and restored settings (which I did twice), I reset all settings, turned off and back on, voila! It is now back to normal......

What a relief!!! 🙂

Fixed mine eventually: https://discussions.apple.com/thread/3948892?answerId=18429139022#18429139022&ac_cid=tw123456#18429139

Ignore gdgmacguy, he appears everywhere on these forums - never offers any constructive help, just the same old message - 'no problems, just stupid users or isolated hardware failure'.
