    I'm seeing the same thing on 2 iphone 5 units. It's only lasting half of what we used to get with the iPhone 4. I'm with Arkanok, the usage stats on the phones are suspect. It appears that usage + standby > than the total time its been unplugged. How is this calculated exactly?

    Excellent test. This tells us something.

    Try doing Settings > General > Reset > Reset All Settings. I had an overheating, battery-draining iPhone 5 yesterday, and the reset seems to have fixed that. Battery life was reasonable today, and the back of the phone was no longer hot.

     

    A restore would probably also work, but a reset takes much less time.

     

    It seems to be similar to the bug that hit many people in the iOS 4 -> 5 update last year.

     

    This not only helped......It cured my problem.

    I could try this, however, I've already done a full restore once without using my backup file in iTunes, I completely went from scratch. To me, resetting all settings seems like it would accomplish the same thing as doing a restore and not restoring from a backup. Though, I suppose anyhting is worth a try at this point.

    Arkanok,

     

    Do you have iCloud and/or sync via wifi activated?    I believe that when you first set up the phone and get it configured, is does an awful lot of behind the scenes activity, syncing and backing up.   Seems that mine did this most of Friday and Saturday, then seems to have settled down since then.  

     

    There have also been a large number of app updates to deal with and I'm guessing that as you update them, the backup/syncing thing will kick in again, to keep everything current.   Don't panic and give it a few days.

     

    ALSO --- Remember that the 4s suffered from poorer battery life than did the 4.   The 5, with only a very slightly larger battery, will probably never live up to the battery life of the 4, but will HOPEFULLY, be slightly better than the 4s.   We'll see.

    In googling the issue I came across this tool: Carat http://amplab.cs.berkeley.edu/2012/06/14/carat-now-on-ios-and-android/

     

    It's supposed to capture stats to help diagnose battery issues.  I've just installed it and will run it for 24 hours.  I'll post the results here.  Would be helpful if others install and do the same - for analysis.

     

    Unfortunately though I've already tried and reset my settings. Hopefully I'll be able to replicate the issue.

    Guys, I did a reset of my Iphone and started using it at full charge.

     

    With LTE and Siri turned off, i basically used it to make calls n send messages using whatsapp n the native message app.

     

    It has been 6 hrs and I still have 90% battery life left, so that's excellent!

     

    It used to drain at least 40-50% even when left idling overnight with all programs turned off.

     

    Resetting might be te key to the battery life problem.

    Are the "resets" most are trying a full start fr scratch without a backup fresh copy of iOS 6, just for craps and giggles?

    I do have iCloud and sync via wifi activated, yes. To my knowlage though, sync via wifi shouldn't actually do much of any syncing unless I tell it too, and even still, 5 hours and 38 minutes of usage from being idle overnight is much too excessive. I don't have iCloud backups enabled though, my backups are still set to my computer.

     

    But, just for comparison reasons, with my iPhone 4, I've had all of the same things set, iCloud always on and sync over wifi.

     

    But, I've just done a reset of settings on the phone and I'll see how things fare in a short time.

    I hit 'reset all settings'.

     

    Battery life is sweet right after that.

    Sorry to hear that.

     

    The lady from Apple Support told me to do a full reset (complete wipe of all data) IF reset doesn't work.  If that fails, then grab your phone and head for the one for one exchange.

    I know we find this difficult, but I would suggest the following:

     

    Once you have dones the netowrk reset thing, LEAVE THE PHONE ALONE FOR A FEW DAYS.   Use it as normal, charge is as necessary, but stop fiddling with settings and let things settle out.   Mine was performing poorly for the first two days, but by Sunday, it seems that it has settled out nicely.
