    I've been really watching the battery drain on my phone the last couple nights. For both nights it had almost no signal-0 or 1 bar out of 6-, no apps are left running.
    The first night lost 6% from 10-6:30
    Last night it lost 13% from 9:30 to 7

    Is this reasonable?

    Pretty much have the unwanted apps deleted. I'm thinking it may have more to do with the low cell service. Tonight I'll leave it in a spot with better service

    I'd say that ~10% loss over 8 hours whilst sleeping is quite reasonable. And just 6% is quite good.

    Is your WiFi automatically turning off during this period too and can you see how regularly the device wakes up over night?

    Tonight was 6% with 2 or 3 bats and WiFi stays on the whole time. Last night's/yesterday's battery chart. [​IMG]

    That looks normal to me. The only thing I can suggest (if you really need the extra juice) is switching the WiFi off when the device sleeps to save battery (although it will use extra mobile data instead). You should be able to find the setting under WiFi > Advanced, and then switch to "Only when plugged in".

    Alternatively, you could purchase the Tasker app, and use it to turn your WiFi, etc off during your usual sleeping hours. There's a guide here.

    Hi..it's really anoying to loose that much power overnight. I bought to my wife a DooGee 800 and I'm kind of jealous about its deep sleep...it drain from 0 to 1% overnight. Why can't we have that????
