5.0.1 update--even worse battery life

Hard reset means wipe the phone and reinstall everything

In addition to the problems noted by everyone above, I am also having a problem with charging just stopping. I use a Mophie Juice pack. Before 5.0.1, absolutely no power problems. After the update, my phone charges to 92% and stops. Then the Mophie Juice pack stops charging.

I also have problems with the phone "connecting" and "disconnecting" from the charger as evidenced by the sound normally heard when plugging the phone into the charger.

Sometimes I can get the iPhone 4 to charge to 100%, but then the Mophie stops charging. As everyone else has said, this must be a software problem.

I did this, Im running what just comes on the phone out of the box, minus adding email. I also went so far as to get into the iTunes folder under App Data and delete and re-download the ipsw file from Apple. I Restored as new and it did nothing. I have 1 page of icons and I have my MobileMe email pushed, everything else is off. Notification center and iCloud are both off. 40% drainage in 7 hours with 2 hours 23 minutes of use. And I can guarantee that I havent used it that much. I have been in class all night. I have 45 minutes on it, if that. Something is staying on and draining the battery. The only thing I have onthe phone is email and contacts. no music or app store apps whatsoever.

Same here I did my phone last night and regretting it as now my battery life is going down very fast. I have used my phone for about a 30 mins but yet it says I have used 1hr and 30 mins.

I was experiencing a very very short battery life ( few hours) and the 4s became hot to the touch. I started turning off photo streaming and I cloud features. Eventually I turned off all I cloud features and the problem resolved. Something also burned through my data plan in a couple of days. This was AT&T's mid sized plan that I had never exceeded. Incidentally I also turned off the auto time zone as it was not working correctly. Whatever it was the heating problem ceased and the battery life is now comparable to my 4 which is acceptable. The heating issue was so severe I could not keep the phone in my pocket and that too is now resolved. Just updated to the new software release with no issues but have left I cloud off so far.

Wiped phone, and restored everything from my computer on iTunes. Took a while but I have had absolutely no issues with battery. Maybe I'm just lucky. I don't live on my iPhone like some, but I use it enough. I only use about 40% of usable space on phone, less than 90 apps, 2 e-mail accounts and a lot of texting. Battery life on my 4 is far superior to that of my old 3G.

Siri Always has the answer.

That sounds *alot* like my use... only I probably do more email and less texting. I get a solid day out of my phone, but it seems like I should be getting closer to ~2 days. I'll give your method a try. Thanks for the details!

5.0.1 IOS has installed night with my full battery and this morning I went to bed I realize that the battery is at 45% aver if apple instead of improving enpeorar hopefully going to take an early

I too get worse battery, but seemingly its to to with 3G.

This morning I know I used the phone for 60 seconds and safari for about 3 minutes. Yet usage showed 45 minutes. Now I've switched 3G off it seems to be more improved.

With 3G and wifi off I'm getting a drop of 2% per hour. With 3G on I'm getting a drop of 1% ever 5-10 minutes.

I've also noticed that system services in location services have grey arrows next to compass calibration, diagnostics and mobile services. I wonder of that's an issue?

BTW have 4s 64gb

The gray means its off. When it turns purple it's active. Those are services that use your location.

My O2 signal got worst since I switched from Sony Ericcson to iphone 4s. Last night I upgraded to ios 5.0.1 and it has been constantly Searching for signal and when it got it, it is only 1 or 2 bars of reception. I turned on Aeroplane mode overnight and battery was ok. But when I switched off Aeroplane mode, the battery drained much faster than ios 5.0. So Apple, pls do soething about it. I am not able to make receive calls and losing my battery life.

I upgraded to 5.0.1, my battery shows no improvement. Tech specs say 200 hrs of standby time, i am losing 30-35% in 8hrs with 3g,wi-fi, time zone and icloud turned off, that means it just wont last a day just on standby. On general usage, i am charging it twice a day or thrice some times, i have to thInk before making long calls. went to the genius bar, diagnosed my battery to be good(on which planet). It's high time apple figured out that a few of the batteries are faulty coz my mates 4s seems to be fine.

Agile's "hallmark" is writing a lot of dumb **** on a project blog so often you hardly have time to actually work.

It's great for everyone but the Engineers, the ones responsible for actually doing the work.

They who should be left alone to actually Get it Done.

Today at 8 am I had a battery charge of 100%. On the train, I surfed for 20minutes, listened to 3 songs, and rang two people with each call lasting 4 minutes. By 3.45 pm, my battery life was down to 8%. The update has infected my iphone4s with a battery issue i Previously never had. I could at least make it through to the next day without recharging with considerably heavier use pre-update. The tech support people advised me that the issue is resolved, I advised them to read this thread! Absolute joke!
