Last night I updated my iPhone 4S to a iOS 6.1.3 and now it drains my battery in extremely fast manner. As I started signing in to write this question from my iPhone I already lost 13% of my battery. I never had a problem with a battery and ive been using iphones since the first one. i miss my morning class because of it because my alarm clock didn't because my phone was dead. Please fix it or have no choice but buy Samsung GS4
iPhone 4S, iOS 6.1.3
all i know for battery life, constantly closing my apps properly keeps life, also not always having location services on and keeping it on silent with no vibrate helps. obvious they are though
screen brightness and also since i experienced this issue with 6.1.3 i did the following and it worked for me (listed this on page 3 but ill re list of people havent looked through the post)
go to settings - mail, contacts, calendars
go into icloud mail and turn each switch off one by one making sure you select the save to iphone option not delete
then repeat this on each email account folder
once all are at off ensure all apps are closed and hard reset phone (home and power) this will restart the phone after a few seconds
let it start up and then go back into the same settings and turn each switch back to on
im not sure if it will work for everyone but it worked for me so if youve not tried it, its worth a go, and seems less complicated than deleting all your apps and having wifi and 3g off etc
hope it works for you
I have seen about 25-30% improvement in battery life after installing iOS7 on my iphone 5

Could you please check your 'processes' list on SYS Activity Manager and let me know what apps are listed as 'running' after you have closed every app manually (from double clicking home and closing all your apps)? I just purchased the $0.99 version of the App and have noticed that after closing all apps it still shows: SYS Manager, Camera, Mail, Phone and App Store all as running ???
The only ones that should be running are Sys Manager and the Phone (since it's monitoring the cell network for calls). Note that I have my mail set to check Manually with no auto check / push notifications and I don't know why the App store and camera should be running either. I even tried resetting the phone after closing all apps manually but the same list of running Apps appears....
I guess it makes sense to compare our total number of running processes (below 'running applications'). After closing all apps and resetting I show 49 total processes running. It first showed 60+ running after reset and took a few minutes beore the number droppeddown to 49.
By the way my phone seems to lasting less today, it's at 48% versus 71% yesterday with approximately the same usage. As far as i know no settings have changed.
