Photos: Cracking open the iPhone
July 9th, 2007 by Staff
After removing the several small screws that secure it in place and disconnecting the two antenna wires, I gently removed the battery and main PCBs as one unit. The iPhone's battery is soldered to the main PCBs. Since I wanted the unit to work when I put it back together, I decided against removing the solder.
If you need to replace the battery on an out-of-warranty phone, be prepared to send the unit back to Apple and pay US$85.95 (AU$100.20). According to Apple's Web site, the process takes three business days and you will lose all data on the phone.
Because of the time involved in actually replacing these batteries, I wouldn't be surprised if Apple just sent each customer a refurbished phone instead of replacing the battery.
Oh this is a good one I have been looking into how to play flac
