I put it back on. The battery life is amazing. I guess there was something wrong with my mail app and I didn't even realize it.
I assume that when that solution works to resolve this battery issue, it's because the email app is constantly checking the email server for new mail regardless of its settings. Whether its on push or to fetch at a set interval, it just constantly checks non stop. So by deleting the accounts altogether and then reinstalling them, the email app gets a fresh command on when you want it to check for mail, thus fixing the problem! Too bad this isn't the only cause for the constant battery drain. Otherwise it would be such an easy fix! Unfortunately I know many people have gotten a replacement phone because the standby time equals use time. It's a bummer because I know that problem existed in ios4 too. Hopefully apple will fix it permanently someday.
Do u keep it on fetch or push?I'm trying to see why mine still does it
it was my mail. overnight it was perfect. i just added back my exchange email
then again i should have gone a day without the icloud exchange email to see if the problem came back. oh well to late. i'll try it next time
How is your usage doing? I put mine back immediately, checked usage and standby and they were different.
right now i deleted my account i'm gonna play with it for a bit then just let it sit....if the usage doesn't go up, then i'll add my icloud account back. if it then starts to go up, i'll committ suicide
okay usage is at 4min and standby is at 12...in a few mins im gonna readd my icloud account, if it remains working, i will then add my .me push email. i had the .me push email but it seems like something nice to have if i don't wanna give out my gmail address to websites where i end up getting spam and ads
and to be honest idk how much i use icloud. i like to back up my contacts on occasion just in case of an emergency....but i'm OCD and that's the main reason i'm so irked about this. THE SERVICE SHOULD JUST WORK PROPERLY lol
with my phone locked the usage is still going up. i just deleted my icloud/icloud exchange account then did a hard reset and now will see if the usage time still goes up even when lock
also someone mentioned the FB app...do you use that?
i also heard push email can. even if u turn it to fetch some glitch makes it constantly looking to 'push'I and my husband bought our 4s the same day and installed the same apps at the beginning. A few days later my husband installed two more apps and then thr problem started: usage time=standby time, battery draining very quickly. We had exactly the same settings in our iphones (including icloud backup and push) and my phone was fine and my husband's not. So he removed one of the apps, deleted it - and the problem was solved immedietely. A friend had the same app installed and the same problem. Solved after removing the app.
I think there may be several apps which can cause it - i.e. hang in background due to some error - even if you switch them off and log out.
Our faulty app was "Map my ride" (for cyclists) but it can be more apps like that.
So start from removing apps one by one - and checking the results.
I deleted both email accounts and now it works, usage and standby time are not the same. Thanks for this fix.
