A report from Nikkei business Publication show us that battery on iPhone G3 is not replacable. It was a Li-polymer secondary battery, like the one equipped in “iPhone 2G”. The battery supply voltage of +3.7V, but the volume of the battery, etc were not printed on it.
The main board was removed from the lower part of the chassis. A Li-polymer secondary battery, which covers a large area of the chassis, appeared. It seemed to be made in China. Looking carefully at the battery, we found that it was connected to the main board by using a dedicated terminal, like the batteries in Japanese mobile phones. In the iPhone 2G, its main board and Li-polymer secondary battery were soldered.
“Probably, Apple used the dedicated terminal to improve the workability,” said one of the engineers.
The Li-polymer secondary battery was connected to the main board by using a dedicated terminal.
At this moment, unexpected words came from another engineer who was examining the Li-polymer secondary battery.
“The battery does not come off the chassis.”
The Li-polymer secondary battery was so firmly attached to the chassis that it did not seem to be easy to remove the battery.
“The secondary battery is placed in the innermost part of the chassis,” engineers said. “Is it possible to replace the battery?”
The Li-polymer secondary battery was firmly attached to the chassis.
