I bought a new iPhone 5 and ever since I got it when I use 3G (or cellular data at all for that matter) the battery life is incredibly bad.  Yesterday my phone only lasted for about 4 hours.  I used up 20% of battery on a 15 minute bus ride.  The battery % display is more like a countdown timer.  The battery life isn't great even with cellular data disabled (with or without WiFi) but it is absolutely attrocious with any kind of cellular data.  I feel like the battery life on my heavily used iPhone 4 was better all around but this new phone is pretty much whenever cellular data is activated.  With my iPhone 4 I could always get through at least 1 day without recharging, with the iPhone 5 I never can.  With cellular data activated I'll have to recharge more than once a day.


What's going on here?  Can anyone help?

iPhone 5, iOS 6

    what's going on here is some minor flaws in the iOS 6, also battery % depends on signal strength while using 3G(data/LTE) it's 1:1, signal : battery life. So if your signal was bouncing bars or anything could have cause excess drain also.

     

    Supposedly they "are working on a update iOS 6.0.1 as we speak" so hopefully all you guys who have upgraded iOS 6 get your problems fixed up!

    you can't do anything until iOS 6.0.1 simple.

    i use an app called, System status, you can DL that and use it to check and see if you're running high @ idle

     

    shows how much % of CPU is being used/  and a battery % shows. helpful. might want to try it.

    shows whats using the memory and all those whistles.

    I just DL'ed a one called "mydata manager" read alot of reviews seems like a good app for data usage reports, and the System status app i think the battery % is close, because when iphone % shows 100% the manager is @ 100% still charging for another 25 mins then hits the green Charged mark, my phone last like 2-3 hours @ 100% battery.

    I also have a iPhone 4S tho... not a 5, Oh, well try that use the app for System status and try charging your phone until it hits the Green charged circle in the App. (your phone will show full charged, keep going till the App says done tho) which is usually like 20-30 mins extra for me after it shows "100%" on the phone.

     

    On another note, I have been recently using that Data app and seems to be pretty good to calculate your usage.

     

    Edit: to post above, 100% for 2-3 hours is with min useage with data usage "on"

     

    we'll find out whats up with yours.
