    I've had my Samsung Galaxy S3 for about a year and a half now and even replaced the old battery (with an OEM of course) because my phone would randomly lose its battery life really quickly and charge really quickly. For example, I would charge it to 100% only to have it go down to 70 if I unplug it. I even tried recallibrating my battery and when I restarted the phone from 100% it went to 32%. The phone would then slowly go up from 32% back to 90% before dropping again. Any help is appreciated.

    Welcome to Android Central! It would help to see some battery stats. Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

    1. The main Settings>Battery screen.
    2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
    3. The Screen category (to see total Screen On time).
    4. The Cell Standby category, if present (to see Time Without Signal).


    Two main culprits are poor cell signal and corrupt SD cards.
