The Apple Watch is a wonderful tool that can keep you connected and help you get fit. It doesn’t last forever on battery though. The good news is you can pick up power straps such as Batfree to extend Apple Watch’s battery life by 27 hours.
The Batfree strap has a 600mAh battery. It is IP68 waterproof rated. It is compatible with Apple Watch Series 4/3/2.[where to get it]
