Battery draining on LG G2 big research


There is two months I try to solve a problem with my LG G2, I have tried a lots of ROMS and kernels with no success.
So I come here because I see a lots of person know the hardware parts.
I loose 7-10% per hours without doing anything, with all roms, on 4.2.2, 5.0.1, 5.1.1, dorimanx kernel and others…

I tried 3 batteries, and the lcd+touchscreen have been changed.
If you have somes solutions, I’m ready to try a lots of things, from the software to the harware.

Thank you very much.
