Plug [HELP] Sudden Battery Drain

Hi, I've been usin hox+ for 1 month now but I have a huge problem. I'm using stock rooted rom 4.2.2 and with elitekernel.

When the phone battery is on the %90 or %80 or some times at %40 the phone shutsdown and when I try to turn on it becomes %0 or %10 at the battery.

So i thought it caues because of my old kernel ( Speedy ) and I've flashed a new one ( eliteKernel ) . I tried installing different rom and see what happens. Still no change...

Some times it never happens but it normally happens a lot. maybe twice a day.. ıf any one had this kind of issue please let me know and if you have a solution please share with us.
