Hi all,

Please could someone take a look at these battery usage images:



The Android OS/Android System seems high. Does this look normal?

Here's the list I get when I look at the Android System item:



I haven't yet upgraded to Oreo as seems there are some issues. Thanks.

I saw this somewhere as I was looking for battery drain issues on the S7. https://www.androidcentral.com/how-enable-developer-mode-galaxy-s7

After that's done go to settings >developer options > running services and look for apps that have a high number. In my case it was an app for a wake up alarm. I uninstalled it. Battery drain issue, gone. Freaky.

Oh, please don't uninstall necessary apps like settings, google this or samsung that.

Google Play services has 12 services the rest just 1 or 2. I presume Google play is fine tho?
