Samsung S7 Battery Draining Overnight

[jliuser]

Last night, at 1 am, I put my phone down, and went to sleep. The phone was around 60% (Screenshot of battery's "Past and predicted usage" from settings in the picture linked below).

When I woke up this morning, it was dead. This happened to my phone once before, almost a week ago.
I have screenshots of the percent of battery that each application uses below. I use Snapchat throughout the day, so that shouldn't be the issue. Does anyone know of any common issue with battery drain from Pushbullet, Android System, or Android OS?

If anyone has any insight to the problem, it would be greatly appreciated. Thanks!

It's kind of tough to tell from this information. Do you live/sleep where your phone might try to have to search for service? Did you get a ton of notifications last night? There are a lot of things that could be the cause, and it's not necessarily those apps, though it could be.

One thing you might do is try to replicate this a couple of times, and then force stopping different apps before you go to bed to see if you can isolate an app. Obviously you won't do Android System or Android OS... but maybe something else?

Also, maybe try signing out of facebook or uninstalling the app overnight and see what sort of impact that has on the battery life.

I have decently good service where I live, and I didn't get any notifications from last night. I think it might be pushbullet. It hasn't used up any battery at all throughout the day, but clearly, when I checked this morning, it was doing something last night. Thanks for the input! I'll try disabling Pushbullet and see if that solves the issue.

I had crap battery life for a bit. Read lotsa stuff graciously supplied by Mr Internet. Found a post which said to turn off wifi calling. Did so. Battery now not superb like some breathless reviews of the GS7 but respectable.
