battery drain 20% overnight

[jackal2001]

charged my phone last night before bed, usually i only get 1-4% drain overnight while sleeping. last night got 20% drain in 8 hours. wtf? nothing in battery stats other than android system at 8%.
Only app i installed was SD Maid and that isn't running. How do I find what is chewing up battery?
I used to use better battery stats on a rooted device, not sure how much it will help now.
any suggestions on apps to find out what is killing my battery now?

Gsam might be able to help a bit.

SD Maid isn't a huge battery user. (I always have it on my phones.)

Make sure you aren't set to automatically update apps - the phone could have spent most of the night updating, and that eats a lot of battery (any transmitter use does, and downloading requires acknowledgement by transmitter).

 

[jackal2001]

nope, i have the playstore to not update automatically.
i downloaded package disabler and disabled a bunch more stuff. I'm going to try it again tonight after making sure i kill all running processes and apps, charge to 100% and see what happens. Hopefully it will be ok again. If not, I guess I have to do a factory reset and start all over again. Don't know what caused it to happen.

Were all your radios switched on (WiFi, mobile, location)? Installing Gsam is a good call and will help you if the same drain happens again.

I can think of a couple of things. Maybe your network had problems and you had a weak signal for a while. Check the signal bar in the battery stats. Do you have any cloud storage app programed to sync/upload at night time? Maybe something went wrong with that or there were many media files to be uploaded.

 

[jackal2001]

wifi is set to turn off (most data usage) in sleep. GPS is always off. Bluetooth is always on. Location settings are always off.
No cloud services. Where is the signal bar in battery stats?

Tap on the graph in your battery stats. This way you can also check the awake time.

 

[jackal2001]

clicking on the graph doesn't do anything. it was plugged in though.

 

[Javier P]

Hummm. I just read that option isn't available in some S6 (maybe AT&T?). Let me check.

It is still there on my tmobile s6 Edge. When you go to "battery" click "battery usage" by the picture of the battery and the graph comes up.

Try downloading CPU Spy to see if your phone is going in to deep sleep? Did you get an update to the OS recently?

You might try booting in to recovery and clearing the cached partition as well.

Honestly, you should keep WiFi on while you sleep, especially if you have WiFi in your house (assuming you do). This will help with a bad network signal and take less power than running mobile data.

 

[jackal2001]

I've found in the past that keeping wifi turned on sucks more battery power. If you don't have apps that constantly hit the network there should be nothing to worry about.

 

[Kelly Kearns]

I keep my WiFi turned on but have it set to turn off when the phone is asleep.

Tested again last night. Had it charged to 100% at 10pm. Woke up at 6AM with battery still at 100%. I changed no settings on my phone. Just disabled more crap using package disabler and made sure all apps were closed. So last night over 8 hrs, I lost 0%.

 

[Javier P]

Pretty good then. Maybe it was a temporary glitch or some of those disabled apps were going wild. Let us know if you manage to pin the culprit.

Any update?

Would you mind sharing what apps you disabled with package disabler? I am mainly interested with which apps you disabler that came stock with the phone

I'll get that together tomorrow or at least try. If you look in the package disabled thread I put a link that tells you a lot of the bloat on these phones. Use it as a guide.
