    does anyone know what I can do to fix this? battery is losing 30-40% overnight. I've tried killing all apps, put battery saver on too, even airplane mode and it's still happening

    Keep your device overnight for charging, do this for a day or two and all of your apps will get optimized. This will make them use much less cpu and they will load faster too.

    When you keep your device on charge overnight and not move it for a long time, it triggers dex2oat optimization. This will create files in the dalvik/art partition which will be used when apps are launched and in turn use less resources. It will take up some space tho, somewhere around 500mb to 1gb.

    Try this method and check if there is still overnight drain after this.

    My phone worked very well (like I loved it) until a few weeks ago it started having issues with chrome (it would freeze and I have to force close it) now the issues are all over the place. Overheating, battery drain, spotify will close after a few if it is not the active app, endomondo will "close unexpectedly" every time, waze will cause the phone to overtheat until I have the system message to close to cool down, even using the camera is a nightmare, the app freeze for 2-3 sec then ok for 1 sec, then freeze again, I have to take the picture on the right moment ... I don't understand why everything is a mess all of a sudden :(

    Turn off auto-sync for all Google items under your account.

    Nothing shows up as taking 30%. it's just normal stats without the 30% drop. this is with the phone WiFi and mobile data turned off too

    I can see that you charged 13 hrs ago...
    Do a full charge before you sleep...
    And then in the morning you'll be able to see what app or service used the battery...
