    iTunes. But if you are on 5.1.1 may want to stay there for a bit longer until 6 x is finally stable for others. I have no issue myself on 6.1.2 but..........

    I have a 4S and updated to 6.1.2 and my talk time is 2:15 with 13 hours 21 minutes Standby. 

     

    I'm not sure how much time I should have, but it seems an improvement over the last 2 updates.

    Was that a model-specific release?

     

    Cause mine came with 6.0 in the box, 6.1 popped up the upgrade path shortly thereafter and now 6.1.2. And even this release came out first and specifically for the i4S about a week before it went general for all.

    nope. mine is iphone 4 which didn't come with ios 6.0 out of the box. it was upgraded. i m now checking the users' comments whether 6.1.2 update is worthy or not.

    So here is where you stand:

     

    13.35/200=.07 {7%) used for stdby  2.25/8=.28 (28%) user talk time  100%- (7%+28%)= 65% remaining. You dodnt post your remaining battery percentage but based on what you did post your display should have been 65% . This is based on Apples spec of 200hr stdby and 8hr talk time. Add and wifi or whatever in the formula for more accuate results.  Per Apple:

     

    • Talk time: Up to 8 hours on 3G, up to 14 hours on 2G (GSM)
    • Standby time: Up to 200 hours
    • Internet use: Up to 6 hours on 3G, up to 9 hours on Wi-Fi
    • Video playback: Up to 10 hours
    • Audio playback: Up to 40 hours

    Hello.

     

    I updated my iPhone 4 to iOS 6.1 through iTunes with a full restore through DFU mode, and left it connected for a long time. And I have terrible batterytime when I have 3G and Mobile Data on, approx. 4 hours in standby. With them off, and Wifi on it lasts for at least a day with heavy usage.

     

    I really want to have this fixed since on my working days I have about 2 hours walk to work and I have mail and other stuff on the internet that I'm obliged to keep updated on. And then I have the same walk home from work.

    So if I have 3G and data on, half of my battery is drained when I arrive at work, and it has happend a couple of times that my phone has died while at work. NOT good.

     

    And since this started I've done numerous full restores through iTunes and nothing has solved this.

     

    Any ideas, and should I update to 6.1.2 or is that a bad move?

     

    Regards

    Izaac

    One fairly solid method of resolving issues with any Apple product is to start clean. In the case of the iPhone that would be a full restore from the latest iOS version and then starting as a new phone. Not importing anything from your previous user backup.

     

    It is a pain to re-setup the apps and non-Apple email and calendars, but iCloud can re-sync contacts.

     

    Worth a try as a last resort.

    Well, if you didn't notice that, I mentioned in my post that I've done full restores through iTunes multiple times with no success, and NO restoring of any type of backup.

    I've had the same problem.  I get between 8 and 10 hours of standby battery life, with Wi-Fi turned off since the 6.1 and 6.1.2 updates.  The battery life might be slightly better with 6.1.2 than with 6.1, but they're both pretty bad.

    I tried: Go to -> Settings -> General -> Reset -> RESET ALL SETTINGS

     

    It didn't seem to help much, and individually finding and returning my settings to their previous values has been annoying.

     

    I'm surprised that Apple doesn't just release a simple app to perform this, and that their Q/C has slipped so much.

    What would Steve Jobs say about this?

    I still wonder what kind of CPU usage those having poor battery times see?

     

    My iPhone 5 (iOS 6.0-6.1.2) can go up to 3 days with one charge with light use. 2 days with moderate use. 1 day with heavy use.

     

    When idling (no GPS, Wi-Fi tethering, active background apps etc), there is about 95-95% idle CPU time (in iPhone 4S it is about the same).

     

    What kind of CPU usage do you see? (I use System & Monitoring Tools -- I wish it could be possible to see a more fine-grained CPU usage map, though).

    I've actually tried by jailbraking my iPhone 4 and installed top (I think it was called that) and MobileTerminal and I couldn't find anything that drew much CPU or network usage.

     

    Read about it in another thread here a few days ago, don't remember which one though. That person found out that an app with Mail in it's name drew a lot of CPU and network.
