Apple Watch Strap with Built-in Battery
For Apple’s products, it is naturally easy to use, but one drawback that cannot be ignored is that the battery has not been durable, and Apple is naturally trying to find a way in this area. Recently, an Apple patent on the Apple Watch has been officially approved by the U.S. Patent and Trademark Office.
As you can see from the patent diagram, there is a small set of cylindrical batteries built into the strap joint of the Apple Watch, wrapped in the material of the watchband. If the patented product is finally completed, it will undoubtedly bring another part of performance improvement to Apple’s special watchband sales, because it can be done like replacing a battery, one watchband battery runs out, and then a new one can be replaced, which is a significant improvement inconvenience.
The Apple Watch sixth generation has been released, and although Apple has done its best to optimize it, the battery life is still no better than its predecessor. And due to the high power consumption of GPS, cellular network, and other wireless signals, as well as sensors such as blood oxygen and heart rate, the Apple Watch still can’t avoid the status quo of charging once every 1 or 2 days.
Apple Watch Strap with Built-in Battery, this solution contains a set of cylindrical batteries encased in rubberized material. Because of their small diameter, they have little impact on the comfort of the wearer. To secure the batteries and prevent the strap from stretching and interfering with wire contact, the patent provides for an internal frame to support the batteries. The inner frame is made of a non-stretchable, high-strength, flexible material, and the outside of the strap completely seals the frame as well as the battery components.
The patent image also shows a perspective view and a longitudinal cross-section of the strap. It can be seen that the battery is a coiled lithium-ion battery with several thin cords holding the battery together and conductive electrodes on both ends of the battery.
According to the design, the strap will contain six cylindrical batteries, and the two cylindrical components at the base of the strap, although similar in appearance, are not batteries and are expected to charge, identify, and protect the battery circuitry. The design, if applied, will allow the Apple Watch to last significantly longer without users having to worry about battery life when using power-hungry features such as cellular networks and GPS.
