Hello everyone, I'm new xperia z2 owner and I juste found something interesting .
I was playing with my new owned babe, and I went to the "test service" secret menu to the "battery health test" and what a suprise!! I found that my xperia z2 has a 3392mAh battery!!! I know that sony rated the battery has a 3200mAh MINIMAL capacity, but what a pleasure to see that some model had an even higher capacity.
Go check yours by taping in the phone pad *#*#7378423#*#* then go to services and then to battery health test.
