Battery problem

[abd96]

It s been aweek since i bought my xperia z2. I have noticed that the battery estimated time is too low compared to another xperia z2

Can you elaborate......have you checked the battery usage percentages between both devices? Does the other Z2 have exactly the same apps/configurations etc......

I compared it with devices on youtube (no major differences wih apps)...
Now my battery percentage is 81% and the estimated battery time is 7 hours with stamina mode and without it
