is it just me (Battery problem)
I have had this z1 for about 2 month now and found this very weird problem with it.
a month ago my phone was shutting off at about 4 percent battery left,
now it's shutting off at 9 percent.
it looks like it might shut off at 13 percent next month, 20 percent in two month....
does anyone have same issue and fix for it? or i am just gonna send the phone in for repair
