    Hi I have an iPhone 4 and since putting iOS 5 on it the battery life has been really bad it drops at a ridiculous rate even when I'm not using it where as it would barely drop any charge when it was in standby. I've tried turning lots of thing off but it makes no difference. I've been looking around and alot of people seem to be reporting this.

    I can confirm this too.

    I had a perfect 3gs with 2 exchange accounts, 1 gmail, 1 hotmail, 1 yahoo and the battery used to work for 3 days with no issues. I dont receive normal amount of emails on any of the account.

    After I upgraded to ios5, every thing was okay, because I there was nothing configured.

    The moment I configured my exchange account, boom!

    Battery started going down.

    8 am it was at 74%

    9 am it was at 56%

    10 am it was at 32%

    and of course the moment i removed exchange,

    at 5 pm it was still at 31%

    So I can guarantee this is related to some bug in the mail or cloud or notifications.

    Even though I did not receive ANY email today.

    I even removed the association of my phone on my exchange server, rebooted my exchange front end server too (yes i am the admin for that server).

    Still the same.

    I am simply going to walk into the apple store and tell them that I want my old OS back.

    I finally solved this issue on my iphone 4.  I had tried everything in this discussion.  I also restored my phone back to factory condition (which interestingly enough leave ios 5 on the phone).  Nothing worked.  Last night, I turned off all notifications.  I tapped settings, notifications, and then turned off each app listed in the "In Notification Center" section.  I turned my phone off.  Today, I turned the phone on and in 3 hours, I still have 97% battery life.  I had been losing about 7% per hour since the upgrade.  I may try to turn notifications back on one at a time as I'd like to be to be able to use them for some things.

    Turning off notifications is kind of defeating the purpose of having a smartphone.  So is turning off GPS.


    There do seem to be ample #s of people who have been able to upgrade to iOS5 and have normal battery life *WITH* not just notifications turned on, but also GPS *and* all the new iCloud features.


    I haven't really seen any obvious pattern here.  Some people claim to have found an incompatibility between iCloud and some other service such as mobileme or microsoft exchange.  Since I have never had mobileme nor do I ever use my phone for email, I can't benefit from the changes they've made.


    The folks at the apple store seem to think the only solution is to turn off practically everything that makes the iphone a smartphone:  gps, notifications, etc.  Since most people don't have to do that *AND* have normal battery life, that strikes me as a lack of acknowledgement on Apple's part that a certain % of their phones have an issue with iOS5.


    Whether this is due to a hardware flaw in a % of the phones manufactured, or due to some "grunge" that has accumulated in the OS since the phone was first set up, is hard to know.  But asking some of us to turn off some of the most important features of the phone is NOT a reasonable solution.

    I suspect the pattern is the first day after upgrading with iCloud enabled, the phone does a lot of data xfers to establish initial sync.

    I was having the same problem and deleted my iCloud account - that did the trick. I haven't tried resetting network settings, but I'm concerned about turning on iCloud even if that fixes the problem - mainly because of data usage. My plan only gives me 500mb a month, so won't iCloud hog a lot of that? Sorry, bit off-topic, I guess.

    I was very surprised when an Apple tech called me on Saturday after seeing one of my posts related to this issue. No resolution yet, but Apple asked all kinds of questions and we agreed that I would test by shutting off iCloud first and then my e-mail accounts and they will call back in the week.


    After some more testing, it seems like when I have Mobile Iron / Corp e-mail on, my drain rate is an average of 16% per hour (at the high end, it was draining at 26% per hour)


    Without the corp e-mail, the drain rate is about 7% per hour.


    The major problem here is that this drain was never this high pre the upgrade to ios5, so I can not blame my corp mail account just yet, but this is realy frustrating as the phone is nothing more then a brick, I expect all things to work for at least a regular 8-10 hour business day.


    I am not a apple fan at all, but the fact that someboady from Apple called me based on my posts here on this forum has given me some hope, great to experience customer service and a real sense of care from them, cudo Apple.....

    @AdamC iCloud says it will only back up when iPhone is plugged in and connected to a wifi connection.

    And for info to others having drain problems, mine has been running with no issues at all since I deleted my mobile me settings.

    Did you by chance turn backup to iCloud on and then click backup now? That will drain the battery pretty fast as it could be a couple of gigs it has to backup.

    Same problem here... fix please soon!


    Why not try the fixes first. The update hasn't been out a week and every update gets these battery threads. This is not a problem with the update but a problem with what you have running on your phone.

    I don't know if this is the right solution but I seemed to be able to solve the battery issue.


    I deleted my mobileme account on my iphone 4.  Shut the phone down.  Clear the iCloud.  Add the iCloud back (with the mobileme account information that I have).  So far I had standby time of 5.5 hours with 71% battery life left.


    I think my mobileme account was trying to access the mobileme server while the iCloud account is also trying to access the same information or server...  Don't really know how to explain it.  But it worth a try!

    I have reset my network settings and nothing changed. I have been watching Cellular data usage every 5 mins and usage is increasing every 5 mins about 2-3 K.


    I have turned off cellular data and it's ok right now.

    Dear KC7GNM,

    I think that this is a bit of a "simple" answer?

    I believe that therea are enough different remarks here to see that the power consumption is an iOS5 upgrade issue! And has nothing to do with what is running on the phone.

    So please APPLE; find a real solution to this issue.

    best regards

    A happy iphone user.

    If you don't use the stock part of your phone you should remove all the tickers so it wont update im not sure how often it updates but it seemed to be alot after i deleted all the default stuff they had put back in it from upgrade to ios5 my net trafic from my idle phone dropped a bit. 


    Also the Find My Iphone although a really nice option can also wear on battery life


    that and disableing icloud bookmarks and photo stream is all I have had to do to get batterly life back to almost what it was like pre ios5

    How many people here have one or more Exchange accounts setup? All of my battery problems since iOS 4 have always been related to exchange, and I'm sure the drain I'm seeing on my 4S with 2 Exchange accounts is no exception.
