Apple Watch is one of the best smartwatches in the world. They are very popular due to their wide range of features and attractive design. But there are also disadvantages to this device, the main one of which is a small battery life. Typically an Apple watch can last between 18 and 24 hours.
It looks like Apple is planning to fix this flaw. Apple patent applications for a strap with a built-in battery were found in the US Patent Office database. The idea is simple enough – the strap will have small holes for the batteries, which will be isolated from each other and easily replaced.
Only the silicone strap is described in the patent applications. But in principle, this technology can be implemented in a metal strap. However, it is far from certain that this strap will ever be released. This is the case with most a = patent applications.
