Rapid battery drain on standby

[rew335]

Hi,
Am new to Android. Have had the phone a few weeks now. When I first got it I had a problem with the camera crashing when I opened the camera. An automatic update appeared a few days ago, and having done that the camera problem appears to be resolved.
However, i now have a different problem - the battery is running down really fast (ie 80 to 17% overnight on standby)! The battery usage show Android OS at 70%. I never have GPS switched on. Any idea what's happening?

No particular service (GPS, Bluetooth, etc) should cause a rapid drain like that, so this isn't a typical "do [this] to save battery" kind of issue... Obviously something is running in the background that shouldn't be.

Does your phone have a decent data signal at the time when this is happening? A very weak signal *could* cause rapid battery drain, so best to eliminate that possibility first.

You could probably try different monitoring apps to figure out specifically what app is the primary culprit here, but honestly, if this were me, I'd just do a factory reset. I know that can be a real PITA, but that normally fixes a lot of problems similar to this, especially where battery drain is very high after an OS update.
