probably there are apps running in the background

do something simple

charge it 100% > use it normally > once it reach 50%

settings > battery > take screenshots of

1) the graph

2) the list of items

3) tap on each item copy all the info and post it all here

if you have taskillers, antivirus, ram and battery apps UNINSTALL THEM

the problem begin when i installed the new SystemUI.apk and it happens only when i fully charge it and then it begin to lag so i switch it off then on and everything return to normal !!

it seems that you have the answer, repair your phone with SUS or PCC or re-flash and it should be back to normal

it might not be fully optimized and that's why it's draining so much battery.
