    I know there are 1billion threads about this, but I think that my example is slightly different from most. Basically my battery is terrible at the moment, today from full charge i got

    USAGE: 3 hours 49 mins
    STANDBY: 7hours 2 mins

    I had been noticing my battery being short lived a lot lately, so for this day I:

    bluetooth: OFF
    Wifi (all day): OFF
    autoupdates: OFF
    location services: OFF
    Email: Fetch manually
    Airdrop : OFF
    LTE: Don't have LTE contract
    Brightness : around 75%

    There are a few other things I turned off but i can't remember them!

    I am a developer so I had the BETA until the GM, I then updated 7.0.1 etc in the usual way, i.e not Betas. I've done semi restores a couple of times (not complete wipes because i hate losing save files etc).

    My question is: Does my battery Suck? Can I qualify for repair/replacement??

    EDIT: I also sometimes use my iPad charger instead of iPhone charger, and I've had the phone for 6 months

    High brightness is a major battery drainer. Do you really need it at 75% brightness? I keep my 5 turned down to about 20%. Outside I turn it up. But I don't use it much outside.

    A few other ones to check in relation to battery (and iOS 7): background app refresh set to off, reduce motion set to on, apple diagnostics set to not send them to apple.

    Try to be on the latest version (7.0.3) and see if you close off your applications yourself if that makes any difference.

    As far as battery, you can try iBackupBot app (on Mac or PC) and see what your battery is like, as mentioned at http://forums.macrumors.com/showthread.php?t=1665221

    You're not alone. I have been experiencing the same problem since the 7.0.3 update and it seems to be affecting the iPhone 5. I would get same the usage time now even though I'm using the same usage habit I always have! I also notice it would skip percentages and die before it gets past 10%!

    So I made the adjustments that you guys suggested and got for following battery

    USAGE: 4 hours 12 Mins
    Standby Time: 9 Hours 28 Mins

    So hardly any improvement, I had brightness at minimum, I also checked the battery health

    CycleCount: 302
    DesignCapacity: 1430
    FullChargeCapacity: 1199
    Status: Success
    BatteryCurrentCapacity: 2
    BatteryIsCharging: true
    ExternalChargeCapable: true
    ExternalConnected: true
    FullyCharged: false
    GasGaugeCapability: true

    So my battery is around 78% of the capacity it was 8months ago. This doesn't really seem to account for 4 hours of use. Should I try a complete restore before go in to the store?

    Your thread is just like many others on the forum. I can't see anything different ...

    What I found with my iPhone 5 is that battery drain is strongly related to signal strength.
    In my hometown, where signal strength is strong almost everywhere, I can reach 7-8 hrs, in the town where I live and work I barely reach 4-5 hrs.
    My battery according with iBackupBot is 84% of original capacity (8 months old iPhone 5).

    Switching off almost all the new features is just useless.
    Signal strength is what makes the difference for me.

    The reason I thought it was different was because I've gone through all the betas unto GM then onto public release without a clean install, As betas are generally unstable/power drain issues, I thought that it might of retained one of these when I went back onto public release.

    Thank you for the info about signal strength, i'll see what it is like at work tomorrow, i think it drifts in and out of 3G but strength is quite high, it is central London after all!

    My problem is that exactly: switching between 3G and edge ... It drains the battery very fast.

    I get the same exact case. I updated my iphone 5 and have done a complete restore as a new phone but still the battery life just lasts about 3-4 hours or so. When I was in ios 6, it still lasted me until 6-7 hours of usage but now it's just 3-4 hours. I use it the same exact amount of time. I wished there was a fix somehow for this. It kinda makes me want to have the new iphone 5s just because it lasts longer through the day than my iphone 5. Kinda sucks.

    I'm not sure a 5s would be any better ...

    So I finally restored my phone with a clean instal, and it has worked like a charm! About getting around 6-7hours with everything back on and brightness back up at 75%, if anyone else has been having troubles and ran betas on their devices, I would recommend doing a clean install/clean restore. It's given me an extra 2-3 hours usage!

    Thanks for posting your solution. I was going to suggest opening an xcode console to see if you had any looping processes. :)
