Reserve Strap Testing with Apple Watch Performing “Better Than Expected”

Reserve Strap, the band with a built-in battery that aims to give your Apple Watch an extra 30 hours of battery, has just put out a video in which they’ve field tested the smart strap. In the video, Co-founder John Arrow says that the strap is performing “better than expected.”

To come to this conclusion, various activities were done including camping, sailing, long distance running, biking and even sleep tracking. The tests showed that the Apple Watch was able to last substantially longer while the reserve strap was being used, as much as 2.7x according to Reserve.

The band is still available fore pre-order for $250 with a goal of shipping November 3, 2015.
