Android system is draining battery

[Galaxy s7 edge]

I got my s7 edge 1 week ago and 2 days ago it started draining battery after an update

Restart in recovery mode (from power off - Volume up+home+power until the phone starts) and clear the cache. (You won't lose any data.)

A new update will drain more battery, because some of the changes were made after the update was written, so it's downloading a lot of data.

I have done this multiple times and the update was done about 2 days ago

I'm getting Really poor battery life for a £640 phone. I have cleared the cache many times still i never see the difference. Is there any other way I could get better battery?

Yes it's got worse after the update but before that it was also not so good

My battery life on the S7 Edge is still amazing.

I'm not sure what you guys are doing differently with your phones

Maybe a factor reset after and update should solve the problem

Just performed a factor reset I let you know if it fixed the issue

I"m getting a ton of battery drain from the OS as well. I used to end my 10h shifts in the ER around 60% on all my previous phones (N7 included). was in the 50's with the 7E and now finish the day in the low 40's. OS drain was 34% today. Not sure what it should be.

I've also done the factory reset many times it still doesn't seem to change anything

Mine was like that. Sometimes 50% or more battery was android system. Always the top of the list and at least 40% usage. Turning off "keep wifi on during sleep" dropped it down to 15%-ish consistently for the past several months.

After a factor reset and some tweaking

To everyone experiencing Android System Battery Drain I have some questions:
Are you using Package Disabler (PD) with Admin rights?
What have you disabled with Package Disabler?

I ask all this as I used PD for a day in my S7 Edge and Disabled all Gear VR services, and that had my Android System up and draining a bit of battery, it even caused some instability, at some point the phone didn't want to Wake Up and I had to force reboot the phone, I then reenabled the stuff I'd ticked in PD and uninstalled PD and my phone went back to normal.

I use PD and remove all bloat

I get the feeling PD is causing problems. Remember that the 'Bloat' is part of Samsung's entire system, it seems that when we 'force Disable' it with PD it causes a ripple effect, and messes with other processes.

I may be wrong though, but I am staying clear of PD for now.
