========================================
As many posted on the forum. I and everyone have similar issue. (This is already upgraded for whole night and a full charge)
CPU also peak at 2.84/2.96 as from Armoury Crate even didn't do anything
Temperature goes high
Battery drain quickly
"Android System" also taking all battery usage from Battery page
What I observed:
From running processes, "Google Play Service" always show up, which not the case in old firmware
What I've tried to fix:
Wipe data (all data not just cache) for Google Play service and Armoury Crate. After cleaned, seems the CPU back to 826Hz, but after I restart the device, it go back to 2.84/2.96 all the time
There may be something wrong on this?

This is the cause... Force closing this would return it back to 8xx mhz 👍 I tried clearing the storage, hopefully it won't return.

Thanks for spotting this. Yes, seemed to be a factor. When I force closed it, the CPU speed returned to 8xx Mb from 2.97Gb and the battery performance seems to return to normal. However, I have now seen that the phone has gone back to 2.97Gb, so will try and kill FOTA again... Done it and cleared storage and cache from the FOTA app, but the CPU speed and temperature not reducing this time....

I just solved this by switching off all app monitoring systems like:
Opti-Flex
Battery Draining Detection
App auto-start prevention

It helped me..

I hope this helps you guys.

Finally... @Anders_ASUS @Gustav_ASUS I think this issue has been solved for me.
Firstly, the new update .47 solved dropping of refresh rate (UI bug )
And Second, heating and draining of batery is solved atleast now for me by Disabling of Opti flex. This issue is not because of Google play store or services, but actually due to bugs in new update.
