    hello guys this is about my iphone 5. i got it a week ago as it was a spare phone in my house but was still used NOT switched off. it came with ios 7.1.2 but i have issues with its battery life. at first charge the phone died at 20% while battery was draining quite rapidly. i checked the battery current capacity on ibackupbot and it was about 1050/1430. i did battery calibration by completely charging and discharging it and the battery life seems to be improved. but when i checked the current capacity it was now 1200/1430. since thn i am doing complete charge/discharge and i have also upgraded the phone to ios 8.3. sometimes my phone dies at 1% but other times it dies at around 10%. today the battery capacity has increased as well its now 1300/1430. whats the reason behind it. i am getting 16 hrs standby time and 6 hrs usage time on full discharge. why does my battery capacity fluctuates. P.s i have not played with hardware yet nor have i changed the battery.

    Either your battery needs calibration or your phones battery is broken. Apple has a warranty covering free iPhone 5 battery replacement.

    Go here:

    and check your eligibility.

    My experience with battery life on iOS 8.3 is no change.

    Not eligible. How can i check whether my battery is broken or not. In my opinion it's good because i am getting a better battery lifespan day by day.

    I know it is only anecdotal, but my friend had a similar issue where the phone died at about 20% consistently, and in his case the batter needed to be replaced.

    The battery life on my 6 running iOS 8.3 is pretty bad now. Did a fresh install too but no use.

    Used to be able to a full day with moderate usage but now don't even get half a day.

    I would say that if you keep having problems with your battery dying consistently at around 15-30%, you probably should look into getting the battery replaced. I don't think it costs very much if you're out of warranty/Applecare. My iPhone 5 had the same issues with dying prematurely and weird battery jumps (like from 80% to 65% in a second), and that phone WAS eligible for the battery replacement. I feel like this is a pretty common occurrence with the iPhone 5 batteries.

    8.3 has been the best one yet with battery life on my iphone 6. ive been able to squeeze and extra 1 hour of usage time out of it recently.
