    I have a Samsung galaxy S4 and just today my battery life has decreased so much. It usually never drains when not in use but now even when my phone isn't in use (like when im asleep) it drains very quickly. I installed an app to check what's draining my battery but it's nothing unusual that I just downloaded recently. It says i used 6% in only 10 mins!! My phone is sort of heated too for no reason. Not sure what caused this literally overnight and how to fix it. Help please!!! I want to fix this!

    Welcome to Android Central! 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).


    You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.

    How old is the battery? If it is over 14 months old it could be just old age! May be time to replace it!
