Why is Android OS all of a sudden using 41% of my battery?

[AC Question]

I've factory reset my phone, location is off, bluetooth is off, sync is off for everything, all the apps I don't use are disabled yet it's still happening. It randomly started happening all of a sudden. Please help!

maybe this happens because bad battery calibration or damaged battery,however I recommend to re-calibrate your battery.

Welcome to Android Central! Are you actually seeing worse battery life overall? Did this happen during a period of inactivity, or were you actively using the phone?

Inactivity. It was during school so it wasn't switched off, just in my bag and I wasn't using it and it drained so badly without WiFi or data on.

The problem with the Android OS listing is that various apps might be utilizing components of the OS, so it's hard to pinpoint what was the main cause. See if it happens in Safe Mode, which can help narrow things down to something you installed vs something preinstalled.
