Early yesterday afternoon, I downloaded the iOS 5.0.1 update on my iPhone 4s. After installing, I watched my battery drain 10% in 40 minutes while doing nothing on the phone. This update does absolutely nothing for battery life. I am beginning to wonder if this is a hardware issue. A recall on these phones would be bad for Apple. This morning, battery still dropping rapidly. My first iPhone. Very disappointed.

 

At first I thought my phone was defective. I took it back and got a new one. This one does the same exact thing. My wife, my boss and three co-workers are all having the same problem. All have done the iOS 5.0.1 update. It is useless.

    Jeff,

     

    Mine seems to be working a lot better now. I've managed this by the following steps:

     

    1) Download the update via iTunes

    2) Reset to Factory Settings

    3) Restore from backup

    4) Ensure that settings-> location services -> system services -> setting time zone is disabled

     

    So far with internet usage and listening to music I've lost 9% battery in 3 hours. Hope this helps

    Nice tip which I'll do, but does this disable the functionality of 'Find my iPhone'?

    I had the same problems as everyone else regarding loss of power in a dramatic (10-15% drop an hour) way on my iPhone 4s.  I was forced to turn off most of the functionality of the phone to conserve power, and still needed to charge at my office and on the drive home in addition to overnight charging.  I downloaded the 5.0.1 (9A405) update through ITunes yesterday and charged to 100% at about 4 P.M. yseterday EST.  I turned on location services, including camera, apple store, maps, siri, weather, and find my iPhone.  I turned on Compass calibration, cell network search, setting time zone (the big killer before) and traffic.  I turned on Siri raise to speak, and I have bluetooth and wifi running.  I turned on iCloud contacts, calendars and find my iphone.  I turned on iCloud backup.  I switched fetch new mail from manually to push (i'm using exchange to get my gmail, contacts and calendar).  I have turned on notifications for phone, messages, weather widget, calendar, mail, stock widget, facebook (I reloaded facebook because on some complaints it seemed to be a battery problem.). I did keep the iPhone from reporting diagnostics and usage though.  In short I turned almost everything on that was previously turned off.  I also turned on kypass which links updates to dropbox which also previously negatively effected battery usage.

     

    I am now (0740 EST) at 51% and this includes about 2 hours and 52 minutes of netflix, web use over wi-fi, emails, and music.  according to time since last fiull charge I have 2 hours, 53 minutes of usage, and standby of 14 Hours and 54 minutes.  All my contacts are still there in my phone directory, being synched with google contacts, as are all my calendar appointents, again through Google.

     

    Compared to before the update where my phone would have been dead in about 6 hours with minimal use and most everything turned off, this update really seems to have fixed the problem, allowing me to start using all the new features. 

     

    I am going to run the iPhone battery down all the way to 0, if it lets me, then do a full recharge and again watch the usage to see if the fix remains in place.  It should, but I want to make sure.  Hope this is an insight into other user experiences regarding the update.

    If the Locatin service is turned completely off, then yes it will disable the functionality of find my iphone. If you only turn off setting time zone off, then your find my iphone will continue to work.

    My Battery Life has seemed to worsen as well, with in one hour of full charge I was lost 10%. I have airplane mode activated and wifi is on.

     

    I remember before iOS5 getting 3-4 Hours before using 10%...

    Hello. I have one a full 0% recharge and am testing the battery today. I will update you guys here to see how everyones phone are doing. Mine seems to be doing veru well, since I have NOTHING turned off. Everything including updates to Apple is turned on, so my battery is doing fine. I will let everyone here know how everything is going.

     

    Everyone please be vigilant of your phones performance today since its the first real world test with the new update.

    I was getting OK battery life before on my iPhone 4S then upgraded to 5.01 and it seems to be draining faster than before.  I've got most push features disabled, location disabled... I haven't tried draining bat to 0 then recharge yet.  I'll try that!  Hope Apple is still working on this and not thinking the updated fixed all.

    Sorry that didn't help. My 4s is now at 24 % after 16 hours of a mixture of calls, music, Internet and standbye. So there is some hope that Apple will get this sorted for everyone.

    I did not have too bad battery life on my 4S before the update however now I find I have the problem.  The back of the phone now gets quite hot when I was reading a book on Kindle and I lost 1/4 charge in about 15 mins.

     

    I turned off location services and the back cooled down and the battery sort of stabilised.

     

    Not happy!!!

    My first iphone and i have to say i was dissapointed about the battery life.

    The update didn't change , so i finally tried Robs solution. I have to admit i didn't think it would work, but it did!

     

    Thanks a lot!
