Double the battery life of your Xperia Z1 with the new Mugen Power case
The phone's own battery has the same 3000 mAh capacity, so you can effectively double the arguably ho-hum endurance of your Z1, plus Mugen's product will serve as a protective case for it, so you shoot two birds with one pricey stone.

I like how it complements the Z1s design.

Update to Android 4.3 fixed my battery issue but if you are a heavy user get and external battery.
