Reserve Strap wants to charge your Apple Watch using its hidden diagnostics port

Apple's first Apple Watch still has a lot to evolve, and its battery life is certainly one of the main things people would like to see extended. Something the Reserve Strap wished to fix sooner rather than later.

Hidden beneath one of Apple Watch's strap slots is a small 6-pin diagnostics port. A port Reserve Strap says can be used to charge the smartwatch, and perhaps even allow further smart straps with enhanced capabilities in the future.

But for now, the Reserve Strap will simply add some extra juice using curved and flexible batteries, greatly simplifying its initial and bulkier design that was using a magnetic induction charger - using the same principle as Apple's own original charger. By connecting directly to the pins, the battery charging  efficiency will also be improved, providing even more battery life and not having to worry about the wireless charging efficiency.

The only issue is that, until Apple makes it official that it's ok to use this diagnostics port, investing in any accessory that uses it is a high risk gamble not everyone will be willing to make. We need only look back at what happened with the first non-official lightning cables, that suddenly stopped working when Apple updated it's iOS. And I wouldn't be surprised to see them do the same sort of thing again.
