Q: 5.0.1 update--even worse battery life

So sorry to hear that. I was lucky - my iPhone 4 had to be charged twice a day after the 5.0 update, but now the battery lasts *far* longer after the 5.0.1 update than it did before the 5.0 update. I'm obviously one of the lucky ones - it's been an amazing update for me. I didn't have any battery life issues with my new 4S, so the update didn't change anything about that device.

Apple has already admitted that this update didn't completely fix all battery life issues, so I'd expect another update in the near future. It *****, though.

so i update to IOS 5.1 around 6:45 pm EST...hoping that it would fix the bug....then around 7 pm my battery was 100% charged...then since i cam back from work and was tired i slep till 10 pm...when i work up found out my batter percentage is 75%...it was not like that before the update...i didnt even use the phone it was on stand by...its so dissapointing that i am thinking of going with android...i have had Iphone 3, 3GS, 4 and now 4S...Apple is just dissapointing me....lets hope they fix the problem soon...or we switch to something else

I have a Iphone 3GS after I install the 5.0.1 yesterday evening I notice the battery was draining alot more then usual so i did a hard restart seem to have corrected the probem I have lost 4% of my battery life in about 2 hours with my normal use but would like to a update to correct this issue

I am having more of a problem now with the update...It seems to drain even faster!

My battery used to drain fast until I installed 5.0.1 last night. 10 hours later, it is still at 90% despite having everything turned on. I'm quite happy with the performance of my 4s now.

My iphone 4 (not 4s) never lost more than 50% of it's charge in a day's use until downgrading to 5.0.1.  It's a downgrade because after only one 2 minute phone call, maybe 4 minutes of wifi based internet usage and about 2 minutes playing a game, my phone just died after about 12 hours of almost no usage.  I even turned off bluetooth and wifi for most of the day.

This is very upsetting and makes the phone essentially useless.

We need better tools for determining which processes are using up the most battery power.  Android can do that!

Like Chappsnet noted, my iPhone 4 S is working much better after the 5.01 update, and I am experiencing No Problems Whatsoever. What am I doing RIGHT?

Same here.  Noticed that the battery lasts longer on my 4S even with all the factory settings on.

I have a iphone 4. After the establishment of 5.0.1. battery was diluted with twice as fast ((

Same here. I hope the next fixes the issue. I hope they don't rush out anything that doesn't fix our issue. Let's get it done apple. This is the reason I dumped my previous device.

My iPad battery started to drain really fast when I updated.

Really strange

I would like to chime in and say I'm having the same problems as a lot of you. Worse battery life, and the upgrade was a pain. I have the 3GS and I've been waiting for the 4S hype to die down before upgrading phones, but I'm now seriously thinking about going over to Android now. This is pathetic!

how it can work for someones not for others, if I think like thath Windows' updates doesn't work for everibody,

I do not want to compare them. However

I want my iphone working in a cool way.

I never had problems with Windows...KKKKKKKKKKKKKKK

I just got my first iPhone (4s), so I didn't really know what to expect regarding battery life. But I can definitely say that after updating to 5.0.1 the battery is draining exponentially faster than it was with 5.0. After only 4 hours of my iPhone just sitting in my pocket, the battery drained from 70% to 26%. That is CRAZY bad! I feel like a fool for updating.

Don't feel like a fool, we are all in the same boat. My iPhone 4S was the best phone I had ever had until last night.

I wish I would have not updated until reading these nightmare experiences. It's sad to say but between last year's iPhone 4, Lion and now this battery issue fiascos, Apple is slowly turning into Microsoft.

I am returning my phone and going back to the 3GS or maybe getting the Galaxy SII.
