Didto kog APM yesterday after reading the thread. They're asking you to pay 1,800 for the replacement and installation. I went to Ayala istore and asked about battery replacement. They informed me that apple does not replace the battery what they can do is trade in the unit and top up an amount for the new phone and maski pila nana ka gig given na Philippines jud imong iphone nakuha and not from any other country.
