Q: 5.0.1 update--even worse battery life

guys,

have all you tried to "reset all settings" under settings -> general -> reset after the update and then condition the battery (i.e. fully discharge, then fully recharge) one time.  i installed and or assited over 10 users now successfully and it worked in every case except one (but the user had not had a chance to do the recharge process, yet).  it dramaticially improves standby performance from 2-4% drain per hr or more to 0.5% or less an hr.  i am on my third day now and the improvement is dramatic. check out process details, settings, etc of my thread here:

https://discussions.apple.com/thread/3484755?start=0&tstart=0

this clears out old and possibly corrupt settings that were creating the issue and also forces a recalibration of the battery.  after nearly 3 days now, my personal iPhone 4S is now performing as well if not better than any previous iPhone (original, 3GS).

This isn't the actual battery dropping. Just how the OS reads the battery meter. It's a fluke. A battery will not physically drop 20% and regain that 20% back 2 minutes later. It's something to do with how the meter is being read.

I have mentioned this before, and will again.  I have had a dramatic improvement once I did a hard reset, followed by a full recharge and full discharge cycle.  I went from dropping charge at a dramatic rate, to 24 hours plus without having to charge and I still have 36% remaining.  I probably won't have to charge until tomorrow sometime.

Apple could be a little more forthcoming with the information required to get the most out of the update, but I don't think there is anything for them to fix.  Just need to get the information out to the masses.

By the way, this same procedure has worked wonderfully on my wife's iPhone 3GS after upgrading from iOS 5.0 to 5.0.1

stoga,

this is my experience also.  once i reset all settings (same as hard reset) and recalibrated the battery (full discharge, full recharge), the battery improvement has been dramatic especially in standby.  after 3 days now, it is atleast on par if not better  than with my previous new iPhones.  what i don't understand is people keep doing restores from backup which merely carries over those currupt settings?

It seems most 90% of people are just installing the OS and not doing anything else. Each phone is different and some need to be power cycled or hard reset and not just the OS installed. It seemed like a pretty simple solution to me. Hard reset, restore as new run down to 0% and recharge. 100% improvement.

I've run it down to 0% and it is charging at the moment. The last 1% didn't last very long though…

More interestingly, I was at the Apple Store today. So I asked a friendly-looking Apple guy what he could tell me about the state of the battery issue. He said that it affects all iOS 5 devices equally, and that it's due to a bug in "one of the scripts." Apple's working on a fix due out in a week or two.

I did a hard reset, let battery go to 0% and shut off. charged to 100% and the last two days it ran out in 8 hours, 1 text message and two 1 minute calls yesterday, no calls today. EVERYTHING off.... wi-fi, location services, blue tooth, notification services....

i used to run a golf gps app on my 3GS for 5 hours and still only use 25% of my battery.  this phone is not useable as is....

When you have problems that bad. Thats when you take it to the Apple store. They have diagnostic equipment there to pinpoint the problem. If its hardware related, they just replace the phone. Does everyone know that the phones have a 1 year warranty unless you buy AppleCare or AppleCare+ then it's 2.

What is the deal? We spend money to have one of the best phones and my battery life drains without even using the phone even when you try to minimize localizations,turn off programs running in the background and have the brightness way down.

Indeed I feel disapointed with this iphone and since the update the battery is not the same , apple should have to do somenthing about this issue!!!!

Not only does the battery drain much faster with iOS5, the phone (iPhone 4) now overheats when I charge it for more than a few minutes (6 or 7 minutes).  It also overheats after maybe 10 minutes of use.  I've tried turning off settings, even reset the phone, it didn't do diddley.  At this rate the phone will be useless to me very soon.

i wanna downgrade to 4.3.3. the battery life is shocking me.

I don't want to install iOS 5.0.1 update for my iPhone 4 because I don't need it after reading your comments. I fully charge my iPhone 4 last night to 100% and unpluged my phone at 9am this morning and now is 3pm and I have 99% battery life. I am ok with iOS 5 and I don't need iOS 5.0.1 for now.

Better wait for next update.

My battery drain rate is 8% per hour, in locked mode, after installing 5.0.1.  I consider this unacceptable and regret my purchase.

Put me on the list of people who didn't have a Problem with 5.0, but after the 5.0.1 update my battery drains twice as fast.  Guess I shouldn't have updated.  All of my settings are exactly the same as far as I know.
