lenovo vibe shot baterry problem

hello,
I recently bought this phone, but baterry cant last even 6-7 hours. even at night, when i sleep and dont use phone, baterry drains around 30% !!!. most of that is CPU usage:confused:.
Does anyone knows or had simillar problem, and how to fix it, is it software or something else.....
Also, device heats up very fast, after 15-20 min od moderate usage, his back is very very hot.
Thanks.

Note 4 rooted weird baterry problem

Hi

So I'm coming to you with a seriuos battery problem with my note 4 n910c

So I bought it of from my friend two months ago and it worked just fine then agter a month or so the battery life went bye bye.

So i take my phone off of charger about 5am and by 10-11AM my phone's battery is dead.

I was a heavy user ao i thought that it's me. So i reflashed wannam stock 3.2 which was the best for me and installed only viber and whatsapp. And the time changed only for 30mina or so.
As my phone is rooted I tried every rom here and tried different combinations of kernels and what not.

NOTHING WORKED.

So next thing normally I thought BATTERY.

And went out and bought a new original battery. And guess what.

The same thing happens with a brand new battery and yes i did calibrate the **** out of both and so on....



So besides telling me go to samsung service center which because of root i will have to pay for any other suggestions.

Thx XDA 4 Ever
