Battery drop after restart topic

Hi. My problem starts few month ago. When i do a restart i got a huge battery drop. I got the juice so my phone wont turn off just false battery level :S i'm using purity with hells kernel, i try lots of kernels but no effect. I tried battery calobration app buz no effect. When i use my phone normally and didnt restart it, everything normal. Someone got a solution to this?Attachment 2596718
