Sony Z1 Battery replacement

[Rickster]

My friends Z1 is doing some weird stuff, phone shutting off at 80% and then entering a 1 hour boot loop (trying to switch on then dying).

Does anyone know how much sony will charge for a battery replacement?

Worst case scenario we have to take it to a repair shop to get it fixed, also any prices?


Thanks.

has he done a hard reset.

a pin or paperclip(or similar) will be required.

He did a factory reset 3 times, is that the same thing?
