    It's not unusual for Android OS to use a substantial amount of battery, since it's the operating system, and will almost always be active to a certain extent. What's more important right now is to determine how abnormal your overall battery life is. 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).
