Apple has continued to improve its smartwatch portfolio over the years, with the latest one – the Apple Watch Series 6 – adding the ability to measure blood oxygen saturation levels. However, one area where things haven’t improved much is battery life, as Apple’s latest-and-greatest usually lasts just over a full day of usage. However, the company might have a solution to fix the battery longevity on the Apple Watch by sacrificing the need for a dedicated haptic engine, or as Apple likes to call it, the Taptic Engine.
“The haptic device may include a battery element electrically coupled to the display, a magnetic element, and a coil assembly fixed with respect to the enclosure and configured to induce an oscillatory movement of the battery element parallel to the display to produce the haptic output,” says the patent description.
Apple’s patent describes a ‘haptic device that moves a battery element in order to produce a tactilely perceptible pulse or vibration along an exterior surface of the device.’
Apple’s idea is definitely clever and might prove to be a major step towards improving the battery life of its upcoming smartwatches. However, do keep in mind that this is a patent filing we’re talking about here, which means the idea might never be implemented and fails to appear on an Apple Watch in the future.
