5.0.1 update--even worse battery life

I can confirm that resetting the iPhone's settings and during a full drain/charge has not resolved the battery issue. 5.0.2 can't come soon enough.

bump.

I also have markedly worse battery life on ios 5.0.1.

Iphone 4, with 5.0 was just fine with batterylife. Upgraded to 5.01 Monday and by noon each day after that my battery warning at 20%-left will pop up. Battery fully discharged by 4pm. No new apps, no phone or app use.except to answer one short phone call.

I will add to the list of disappointed customers here and confirm that the 5.0.1 update has negatively affected my 4s battery life. Trying the reset and battery drain fix now, but after reading many posts here I'm not very hopeful. My wife keeps saying it's not that big of a deal, but it is! Especially considering how much we paid for our phones plus AT&T's fees. We should at least get a battery that lasts more than a day before needing a charge, especially when it's barely even being used. I hope 5.0.2 fixes this problem or I may start looking into other phones.

Still have a 3GS here and have always been pleased with my battery life. When I upgraded to 5.0 I noticed the battery seemed to drain slightly faster. So, when I saw the 5.0.1 update that stated it would fix that bug, I of course went to upgrade immediately. What a mistake. Since upgrading to 5.0.1 I can almost watch my battery life melt away.

Since I haven't done anything different as far as settings or my typical usage, this was very curious to me and posted on Facebook to find out if any friends were having similar problems. I had a friend suggest turning off the percentage monitor on my battery. He said someone told him to do it and it helped.

I did this and it has totally made a difference!! That makes NO SENSE to me why that would effect the battery life ... But it really isn't draining like it was.

Perhaps it never really was and there is a bug in the % battery monitor itself ... I don't know, but at least I am not looking at my battery every 5 min now stressing about it!! (:

I have the same problem...

Its a smartphone people. Of course its goin have terrible battery life. TheUpdating will not improve anything.

Just being a smartphone doesnt automatically mean it is going to drain the battery. My i4 had great battery

life before OS5. So how is it that a software update turned my phone into a battery vampire?

Its not just limited to the 4S phone, its all apple phones running OS 5. Obviously OS 5 is a problem that's why it's been splashed all over the media. Not only does it kill battery life but also phone reception and a host of other problems. Another week and OS5.2 will be out. Hopefully that will solve the problem.

Yes, same happens to me. Have iPhone 4S. After Fix 5.0.1 battery life drops at a rate of 10% per hour without using the phone. Only open 3G without any activity.

Uh, no. My iPhone 4 worked well enough until the 5.01 update. It loses about 15 percent battery life when it's sitting overnight on my nightstand and not doing a thing.

I agree with you totally yesterday i upgraded my iphone 4 from ios 5.0 to 5.0.1 thinking that battery issues would be solved but after upgrading and charging my iphone to 100% i found out that its a usless upgrade as now my battery life is even shorter it drains even faster on standby mode ridiculous i should had updraded from ios 4.3.3 as i had no issues with 4.3.3 dam hope apple brings out a new update as fast as they can because i am frustrated with this battery drain problem and also a new problem is ios 5.0.1 eats lots of ram without having any app running in background, on ios 5.0 i had minimum 350 ram free but after upgrading i am left with only 250 ram free **** with this update hope apple soon solves this issue

My iPhone 4S seemed fine with iOS5, in fact it was getting better than advertised times. After doing a wifi delta update to 5.0.1 I noticed a slightly faster battery drain during standby and general usage than before. Standby drain was about several percentage points per hour compared to the advertised average of half a percentage point per hour. I'm not so sure what happened but after a system restore (setup as a new phone) and a battery cycle, things seem to be fine again. Standby drain is now about 0.4% per hour with moderate push use and about 0.1 - 0.2% with light push use. I have location services on for almost everything including timezone. Usage tests yielded about 8 hours of Netflix on wifi. My iPad went through similar changes too except the location status indicator is always on for some reason (time zone), but doesn't seem to be affecting battery life.

5.0.1 updtae seems to have done nothing to improve my battery life. I have iCloud, Time Zone and Bluetooth switched off. Occasionally turn on wi-fi, otherwise off.

Moderate use of push, location services and Siri.

I cannot fathom why the batter is so much poorer than my iPhone 4 (over a year old of constant usage).

I wish I could get my iphone 4 (16GB) back... The faster processor, enghanced camera and Siri all seem quite pointless when the battery is as awful as it is... and I am £600 out of pocket :-(

Also noticed that my iPad 2 is experiencing similar drains, battery used to last a whole week at work, now with similar usage it only lasts 3 days.

I AM NOT HAPPY!

Will consider waiting before rushing out and getting apple's latest kit with faults like this that are not even publicly acknowledged!

12 people I know have iPhone 4S upgraded from iPhone 4.... ALL have similar problems!

Poor Apple.... Poor!

Did an experiment last night. Charged my phone to 100% then put it in airplane mode. Usually i wake up to 25% of my battery drained, but today i woke up to 100%. Switched airplane mode off and within an hour my phone dropped 10%. Unreal.

I have never paid to much attention to this screen, but have started looking at it since my battery dies so quickly. I unplugged by phone at 6 am this morning. and by 7:18 this is what is showed. In a little over an hour, it has dropped 18%, and yes I even had it plugged in again at this point. Since the usage and standby time are the same, does the phone think there is something constantly running? In that hour I didn't even touch my phone, I made 0 phone calls, was not on the web, text, nothing. It just sat there while I took a shower and got ready for work, and then drove to work. I received about 7-10 emails in that time. Other than that, no usage.

Another hour later, and I am down another 14%

In the 10 mins it took to type this up, it dropped another 4%.

This is just nuts. How did an update to 5.0.1 do this to my phone? Is apple replacing these, since I can't undo the software update????
