LG G2 Android OS battery Drain

[James Skinner]

Got a D802
Battery Drains every 1% in 9 minutes when screen is off on HSPA (Good Signal aswell) on Wi-Fi it is every 50 minutes it goes down by 1%.

Also when I am on the Phone browsing the internet and Facebook it heats up to 38C, is this normal?

When I had Cyanogenmod it was a lot better, but it kept heating up to 45C doing the same thing (Facebook and Chrome)
Attached some Screenshots

Please help me

Welcome to the forums.
Have you received a new update recently? If so, have you tried a reset?

Thanks,
Had an KitKat update in May and since then I have done 4 factory resets.

Since you have done the factory reset, multiple times, I would try reimaging the phone with the factory KDZ/TOT files, there is too many odd things here... Android should not be holding the phone awake, mobile data radio should not be drawing that amount of power, heat should not build up that much with such simple tasks, etc. And since you were on CM, you have obviously flashed the phone, so I would return to a known, good, stock configuration and see what happens first.

Hi, Yes i have just done that last night and it worked battery drained 2% overnight and battery temp is at 26C idle and reaches about 35C when in use.
Android OS still uses 5Hrs but i have had 3hrs screen time max brightness and it is still on 27%.
I think that is good?
Thanks for help
