To find out what’s inside the new Apple Watch Ultra, you could smash it with a hammer. Or you could do what iFixit did, which is carefully disassemble the new wearable.
Among the items found is a battery that dwarfs the one in Apple Watch Series 8.
Apple Watch Ultra battery is huge
With its 49mm display, Apple Watch Ultra is the biggest wearable to ever come out of Cupertino. It offers plenty of features for outdoor enthusiasts, but even city dwellers are intrigued by the promise of multi-day battery life.
Apple accomplished this the old fashioned way: it put in a hefty battery. An iFixit teardown of the wearable shows that it has a 2.1 Wh battery. That’s 76% larger than the 1.19 Wh one in Series 8.
Early reviews of the Ultra say that Apple’s estimate of 36 hours on a single charge is conservative. The device can go for two full days.
It’s easy/hard to repair
The Apple Watch Ultra opens from the front and the back, but that doesn’t necessarily make it easy to repair. Even the iFixit repair expert broke the screen while removing it. And just opening the case damaged a gasket designed to make the device waterproof.
On the other hand, the interior components are held together with screws, not glued in. That makes the Watch easier to work on. Just be prepared for dozens of screws.
