Hellow I'm a happy owner of the xperia z for 10 days, but I'm facing fast battery drain when using the phone. When Im just browsing the phone, battery goes down 1% percent every 3~4 minutes... When gaming battery drops 2-3 % every 5 minutes. I need some help, I didnt charge the phone the first time for 8 hours, but i read it is not necessary. I'm rooted, 4.3 jb, doom kernel v21. I have deleted some of the bloatware and i don't have WiFi and data on all the time. Also media server sometimes goes up to 21% in battery usage.
That battery drainage seems normal to me. Playing games needs alot of battery. Battery usage depends on several things, how high is the screen brightness etc.. To your media server: are you listening to music with your phone? Or watching videos? All this is done by media server.
