    Recently my battery on my Samsung S3 mini is draining really fast. For example I would charge it to 100% around 9 and by 1 it would need to be charged again. This only seems to have happened in the last two weeks. What ever new apps I had downloaded I uninstalled them but it hasn't helped. I have the phone about 16 months now.
    Anyone have any ideas what I could do?

    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).


    Also, a corrupt file on an SD card can cause significant battery drain. Try unmounting the card (in Settings>Storage​), removing it, then rebooting.
