Stopping kernel WakeLocks, during mobile hotspot

[xyzqwerty500]

This shooting up of android os process battery usage is only after the root.

Google play services and other GAPPS have already been removed from the whitelist of power saving. I have been using my mobile hostpot for about 6 hours and 6 hours standby after it and this is the usage through Better Battery Stats app, from full charge to 39%.

Samsung smart manager shows android OS as the major culprit.


Also total computed power usage doesn't amount to the decrease in battery power. Total power usage is amounting ~ 1000 mAh but battery is of 2600 mAh, this is happening after root and I have fully drained and charged while switched off to full to calibrate the battery, but same.

Earlier real usage time was equal to what is now but estimated usage time was just double when all GAPPS and gms were running in background.

I am posting the screenshots. Can somebody let me know the reason for this and how can I disable the wakelock visible in the Better Battery Stats screenshot?

Does anybody have an idea of reducing Mobile Radio power reported by android OS process?
