looks like i have got to do a full reset too.

You may if you have the time to do.

Btw, a quick feedback here after all the hectic tasks performed. I got like a 3% drain over the night (on full data mode, from 1130PM - 7AM this morning). Looks good to me.

Usually I'll do a wipe cache after each update installation band usually do the trick
Was from OP, AOSP based rom previous so every single update I did was clean flash.

Still not use with OTA type of upgrade, kinda dirty flash to me.

redownloading all apps and backup will be really pain.
You actually can use HiSuite to back all your stuffs in your phone before perform a clean wipe then restore it back again once the format is done. HiSuite works just like iTunes backup / Xiaomi PC Suite. It helps alot tho, of cause it cant compare with Titanium backup la.
