The Apple Watch 2 may come with up to 35 percent more battery capacity, based on an alleged leaked component destined for the new device that is expected to be revealed this fall.

Photos of a 334mAh lithium-ion battery that will supposedly be used in the 42mm version of the Apple Watch 2 surfaced on the Chinese micro-blogging service Weibo over the weekend, showing why owners of the second-generation wearable might not have to charge their devices as often.

Since the first-generation Apple Watch has a 246maH battery, a 334mAh battery would be a huge upgrade to battery capacity. The Apple Watch 2 is expected to add GPS, so much of the extra juice could be going to support that feature.

Along with revealing the bigger battery, the Weibo user also claims the Apple Watch 2 will add a blood oxygen sensor to the device and a more powerful processor.

Previous rumors have claimed Apple Watch 2 won’t feature any major design changes. Apple is expected to unveil the upgraded device this fall along with the iPhone 7 and iPhone 7 Plus.
