Q: 5.0.1 update--even worse battery life

Ok, I have 3GS, 4 and 4s iphones. All of them updated to 5.01.

3GS and 4 running Vodafone as carrier.

4S running TIM as carrier.

Only 4S, after upgrading to 5.01, shows battery draining problem (at an incredible rate, believe me!)

Both 3GS and 4  show really acceptable battery usage.

Hope it helps Apple engineers investigating the problem and get a fix asap. Erase all content and settings (and setup like a new iphone) did not solve the problem.

I have to recharge 4S at least twice a day to be able to go home at night with 15% battery!

It's a really ugly situation. I suggest giving it the maximum priority!

Thanks for the 5.0.1 update guys I am now confident you use all of us a beta testers and I am tired of all this. It’s thesame story with the 4.3 update when my battery would drain from full to not in lessthan 4 hours. Since I've updated to iOS 5.0 and yesterday to 5.0.1 I can barelyhave more than 5 - 6 hours of battery life at stand-by. If I go and make a callor browse the net for 10 - 20 min a day the battery would drain in less than 4hours. This is just wrong. I am happy with my iPhone when it works and this iswhy I have placed an order for the new iPhone 4S but if it’s going to beplagued by the battery life I think you will lose yet another customer.

At least I'm not alone, or imagining, that I thought my battery life was worse after the update! I used an app for about 20 minutes shortly after the update, and watched my batter go from 98% to 72%. I thought, well maybe its just recalculating this initial post-update charge. But then the 2 days following the update, I've noticed the same thing! Hard to believe their fix actually made things worse.

Interesting.  I have a 4, my husband has a 3G.  We did the updates through the Settings (I just found out you could do that! lol).

My husband's 3G is worse since the update. 

Mine is a little better, but still not like it was before the original update.  I'm still not happy with it.

Doesn't matter if we're on wi-fi or not.  Seems like it's okay for doing a little of this or that.  But once you really start using it, the battery begins going down fairly quickly.

I also have a iPhone 4 (not S) which seems to drain more battery than before under 5.0.0.

It also feels slower (like accessing some input, starting up the camera, ...).

Without using the phone much (no phonecalls, just checking some mail) it is now after less then 12h

down to 50%, I would say before I would have had 60-70 percent left.

Is there any menu or tool showing the battery consumption per application?

Thats quite handy on my Android phone.

Btw, the UI of my my iPad2 feels faster with 5.0.1, did not really notice a battery life difference there.

I have worse battery life also.  Didn't really notice it with 5.0 on my iPhone 4s but after upgrading to 5.0.1 and starting at 100% around10:30 am this last sunday, to approx 6:45 PM I had about 4% remaining before I charged again with fairly lite data use, brightness turned way down, bluetooth off and wifi off.  Normally it would last quite a bit longer.

I did notice that after I ran my battery completly dead and then charged up that it has gotten better then the first day I had ios 5.0.1 but its still not what it was on ios 5.  3g calling and data REALLY seem to be draining the phone, and wifi web searching and texting are draining it more then before but not as much as the 3g.  3g is really killing it.  I used maps to find a place on gps and maybe 10 minutes worth and it drained 10% of my battery.  Thats really bad. Ive made 2 calls today totalling 5 minutes on 3g and it ate 3%.  To me thats far too much.

They're doing something. I had a call from an Apple rep who'd read a post I made in this thread. Unfortunately, I lost signal before I could answer all her questions, but she asked me all about my usage etc. I told her that my two year old 3GS was holding a better charge than my 4s.

At least they're still looking into it. Maybe another update soon? She said they were sure it was a software and not a hardware problem though.

Of course its software, my iphone 4 on the last ios 4 was never this bad.  It wasnt this bad on the first ios5.  My hardware didnt change, only the software did. 

OK, just fully charged my phone and within an hour it droped 25%. This is complete BS I havent even used it, maybe one or 2 text and looked at my email thats it. Issue a fix ASAP.

I have a 1 year old 3GS and I had this problem of battery draining out. Yesterday by evening the battery was totally dead, the only thing I did yesterday was about 10 mins of data usage. Now this morning i get a notification that there is an update for 5.0 and the first item was it fixes the battery life problem, I was happy and gladly did the update. But the problem persists, and I think it is even worse. Battery life dropped from 100% in the morning to about 26% by afternoon, without any use.I did hard restart, looks like that din't fix the problem.

I also got a call from Apple, but I've yet to respond since I turn my phone off to retain battery life. 

In case it is useful information to anyone reading,  when I do not put my phone into airplane mode and I am in an area without service, my 4S gets hot and uses about 5% battery per hour when it does nothing but sit in my pocket.  In airport mode this type of drain doesn't occur.  Of course, this is anectdotal.  I read that perhaps a bug regarding Exchange access was causing some sort of loop, in turn causing battery drain... since I did have such a profile enabled for Google calendar access, I turned that off. No change in battery life.

Battery life has been at least as bad with the 5.0.1 update for me. I make sure I shut all apps down when I am done using the phone. I did a full chage when I got to work this morning and nine hours later the battery is less then 10% with no apps running.

Time since last full charge:

- Usage (3 Hours, 24 Minutes)

- Standby (5 hours, 45 Minutes)

And this was with not using the phone. Other then receiving 1 text message which I made sure all apps were killed immediately after.

Strike 2 on iOS 5.

FYI this was with a 3GS.

Same me, on my iPhone 4S iOS5 was pretty good, but after update to 5.0.1 is f***ing ****!!! 5 hours battery life when iphone is on stand by?!?!? ***??? APPLE COME ON!!!

I did the upgrade to 5.0.1 and I was using in NYC and the battery went from 100% to dead in less than 3hrs. My 4S didnt have any issues when it was in 5.0. Apple - believe us.. battery life is getting worse and worse and stop blaming on some software bug and accept the truth and move on .. whatever the truth you (Apple) are trying to throw it under the rug.!!!!
