According to 9to5google, according to its sources, the Pixel Watch lasts up to a day on a single charge. This is the estimate Google currently has at this point in the pre-release lifecycle, and may change prior to launch. This means that its capacity will be less than 300 mAh.
And 9to5google says it couldn’t tell if Always On Display (AOD) was enabled – the Pixel Watch was tested under it. Another question is whether Google has included sleep tracking in this number and whether a full charge allows you to use the watch all day and then track sleep without having to top up until after you wake up.
Overall, that battery life is pretty standard for Wear OS and matches what Fossil Gen 6 is touting. Samsung claims 40 hours, but our experience with the Galaxy Watch 4’s 40mm and 247mAh battery is also close to today. The larger Galaxy Watch 4 at just 44mm in diameter appears to have fulfilled Samsung’s 40-hour claim consistently. Meanwhile, Apple only touts the 18-hour Apple Watch when 1 hour of workout counts, but most users see better endurance.
Additionally, the site says the Pixel Watch doesn’t offer particularly fast charging via a magnetic to USB-C cable.
