Well it looks like there is a chance that future phones will be required to have removable batteries is the new law is passed this will include iPhones. Personally I think this is excellent. Yes I know phones will be a bit thicker but small price to pay to be able to just swap out failing batteries and recycle them.
Wondering if Teracube might consider this for their future phones. Maybe use a phone battery style that is already abundant?
