Try erobot v13.4 + Ultimate Kernel 63.08 new Wolfson Extended + L Speed 1.3.3.4 Tyrant from PlayStore, I'm not sure if this works to cure your battery drain.

Next time try charging it using non fast charger - lately with my stock SGN4 battery having this issue but mine starts at 10% - it will slide down to 0% in no time - after i charged my battery using normal charger (in my case i used Aukey usb port fast charger which have 5+1 fast charge port but i choosed the non fast port) so far so weird things as this one happened.

both also stable - it depends how OCD is to anybody to accept the mini downside of both rom.
v.14 - micro stutter,battery vampire but on the good side it is fast,smooth,many² fonts,stable.
v14.04 - no micro stutter,battery friendly,stable but doesn't include font.
why must you choose super full wipe in aroma?
I choosed full wipe is good enough and my internal storage content is still there.

screen off memo

that's the a7 keyboard

i don't like the implementation of a7 stuff, it breaks things

But why ?

dirty flash will do

awesome! thanks! and all this while I had to manual dl for like what... 7+ hours >.<

So after all this while, do you still come across the problem anymore? Or is it solved permanently?

Mine always drop from 20% to 0%. Running on Android 5.1.1. No root. When I leave the phone to charge overnight, it will go normal till 15%, then the drain will speed up till 7% and the phone will shut off.

Any ideas?
