If there’s a downside to the Apple Watch’s slim profile and wearable design, it’s the fact that you still need to charge it. While battery life has improved steadily over the years, an Apple Watch will still only last a day or so of full usage. But Apple may have an idea to fix that.
Basically, a portable Apple Watch battery that could be embedded in a watch band. To give your Apple Watch a bit of extra juice, you can attach one part of the strap to its rear, giving it some additional power via indicative charging. It may not give you days worth of battery life, but it could be a great source of additional power on the go.
