    Hello...I have had my S7 since launch on Tmobile. Overnight my Battery drops about 20% to 30% and I am not sure why. I went to Reno on vacation and the battery only dropped about %5 during the night.

    What would be making my battery drop so much at home? I have a full signal with the cell coverage and my WiFi. I have tried turning the Wifi off, but that doesnt make any difference.

    Over night, here are the Battery Usage stats:

    Andriod System: 32%
    Screen 22%
    Andriod OS 21%
    Cell Standby 6%

    Any help would be nice

    Thank you in advance

    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.
