    My phone is a model SM-G 900T Starting from a 100% charge I get an unreasonable drop in the usage of the battery according to the indicator at the top of the screen. The the amount of battery left shows a much slower rate of decline after an hour of use. The use I am referring to is consistent nonstop Web surfing over a very strong wifi signal with 2-3 hours nonstop.

    I think I need to recalibrate the battery meter. How can I do that?

    Recalibration is usually achieved by charging up to 100%, then using it normally until it shuts off from low battery, then charging back up to 100% again. Repeating the cycle 2 or 3 times might be helpful.

    If the pattern persists, it would be helpful 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).

    Thank you.
    I will try running down to turn off.
