Android System drains battery

I've had an LG G4, model H815 at Android 5.1 for the past two months. So far extremely satisfied, but it's been acting up for the past few days - battery drains for over 20% while I sleep for ~7 hours, and apparently Android System (specifically the GPS) keeps it awake and drains over 60% of the battery.

I keep GPS on high accuracy and I use the smart settings the phone has, but up until a week ago or so it didn't do any harm and it only lost about 2-5% every night - Same goes (more or less) for my previous phone. LG's subsidiary in my country just pushed an update a few days ago, so it may be relevant, but I don't recall if it happened before it or not (sorry).

I'm attaching a few pictures to this post, if there's any app you want me to run and post its output just let me know.

Sudden battery drains

Any idea why my watch suddenly updates so many apps at once that causes a huge battery drain? It's the second day it happened already. The watch runs fine through most of the day till somewhere in the evening, as shown in the battery stat picture, when the battery just comes crashing down. I've never had this issue before until yesterday and today has seen the same results. I require some assistance please.

New Huawei g play mini phone drains battery very quickly

Here is a screenshot of my battery drain

Is it normal , or should I go to service center ? My previous phone had much less sloppier curve . When I bought the phone I charged it upto 100% and then started using it , though at the shop they told me to charge for 3 hours. Is it because of this ?
