Although using One X+ battery bad battery life

view story

http://forum.xda-developers.com – Hi, i recently changed my battery to the one x+ one and hoped that I got a better battery life with this. It is better indeed but never the less the battery doesn't last a whole day. What I found very confusing: Gsam Battery monitor always shows me an app usage percentage of about 90%. I thought the display should be the one with really high percentage? I don't play games, I use the phone a lot but the absolute max I got for screen on is nearly 3 hours. With the old battery I never got more than 2. I also installed wakelock detector but the results make no sense for me. Internet, maps, (HowTos)
