Battery insanely bad
Hi.

Why is the battery after the 2nd week as bad as no other?

Sony the worst battery, but the phone is not good!

Kind regards

Akku wahnsinnig schlecht

Hallo. 

Warum ist der Akku nach der 2. Woche so schlecht wie kein anderer???

Sony das absolut schlechteste Akku, aber das Handy auch nicht gut! 

Mfg
