Hi. I'm curious after update zr to kitkat the android system use my battery 14~20%. I did the hard reset once but the battery usage still very bad. The Google service only use 6%. If I not mistaken during JB 4.3 the android system usage about 5%. Look like the android system killing my battery. Not the goggle service as many kit kat user faced. I'm root and location service disabled. Anyone having same issues?
