Battery size reduced on XZ

[suarez1]

wwhen i first bought it and tested its battery, it was 2980mAh, but not after only more than 1 week, it was down to 2800mAh. IT can't loss capacity so fast, is there some problem with my XZ?

@suarez1121212 How did you test the battery? Did you use an app like antutu or cpu z?

[suarez1]

no,I used sony's testing code (*#*#7378423#*#*) => battery test

@suarez1121212 Best thing you can do is to have the phone examined by your Local support.

It seems there is a minimum mAh for a battery and an average. Usually, the average is advertised.

No at first my phone was 2980000mAh then it reduced to 2799. I can't believe it dropped so quick ly after only more than 1 week using.

You have to remove the motherboard to replace the battery too. I hate built in batteries! Nobody would worry about battery health or the number of charges if we could bung a new battery in every six months. These things are disposable items and only last as long as the £5 battery inside. It isn't like battery life is great out of the box and yet it's downhill fairly rapidly from the word go.

Why would you have to remove the motherboard to replace the battery? and no, Xperias are not disposable phones. I think you are over analyzing this, contact your Local support with your thoughts and/or concerns and/or questions
