Another comparison is the 300 mAh Fossil Gen 6 which touts 0-80% in “ approximately half an hour.” It’s nowhere as fast as Apple’s current offering (Series 7), which touts 0-80% in about 45 minutes and 0–100% in 75 minutes over USB-C with a 20W adapter. Meanwhile, we’re learned that the Pixel Watch does not offer particularly fast charging via its magnetic to USB-C cable. Apple, meanwhile, only touts 18 hours for the Apple Watch when counting a one-hour workout, but most users see better endurance.
Only the larger 44mm Galaxy Watch 4 seems to hit Samsung’s 40-hour claim consistently. Samsung claims 40 hours, but our experience with the 40mm Galaxy Watch 4 and its 247 mAh battery is also around a day as well. In all, that battery life is pretty standard for Wear OS and matches what the Fossil Gen 6 touts.
Another question is whether Google incorporated sleep tracking into that number and if a full charge lets you use the watch all-day and then track slumber without needing to top-up until after you’ve woken up. We could not learn under what conditions - namely, if the always-on display (AOD) is enabled - the Pixel Watch was tested under. This is the estimate Google currently has at this stage in the pre-release life cycle, and might change before launch.
According to a source, the Pixel Watch is said to last up to a day on a single charge. Google’s upcoming device has an exact capacity of - as we’ve learned since our original report - just under 300 mAh.
We previously reported on key Pixel Watch specs like the chip and health sensors, and can now provide some details about the battery life of Google’s first wearable.
