How does the GPS battery life of the Series 10 compare to other smartwatches

For comparison:

- The Apple Watch Ultra 2 has a rated battery life of up to 36 hours, double that of the Series 10[3].

- Garmin watches are known for their excellent battery life, with some models lasting over 2 weeks on a single charge[4]. The Garmin Venu 2 Plus can last multiple days even with GPS usage.

- Samsung Galaxy Watch models also tend to have better battery life than the Apple Watch, though the battery life decreased when Samsung switched to Wear OS[4].

The Series 10's battery life is a limitation, especially for fitness enthusiasts who rely heavily on GPS tracking during workouts. While it can last through a day of moderate use, heavy usage like GPS-tracked workouts will drain the battery more quickly[1][2]. The Series 10 does charge faster than previous models, reaching 80% in 30 minutes, but it still requires daily charging for most users[2].

How does the battery performance of the Series 10 change with continuous GPS use

The Apple Watch Series 10 has a rated battery life of up to 18 hours, which is the same as previous models[1][2]. However, battery life can vary significantly depending on usage, especially with GPS tracking.

GPS Battery Life

- During a 30-minute GPS workout with notifications mirrored from the phone, the Series 10 used about 10% of the battery[3].

- For longer runs, the battery drain is more significant. One user reported their Series 5 used half the battery in 2 hours with GPS and music playback to Bluetooth headphones[3].

- Another user was able to track a 6 hour 50k ultramarathon on a Series 3 GPS-only watch, finishing with about 30% battery remaining. They used their phone for music playback which helped conserve the watch's battery[3].

- Enabling Low Power Mode during workouts can help extend battery life by reducing heart rate sensor frequency[3].

So in summary, the Series 10 should be able to track GPS workouts for 3-5 hours before needing a charge, depending on usage. Streaming music, using LTE, and frequent heart rate readings will drain the battery faster. Bringing an external battery pack or your phone for longer runs is recommended to avoid running out of juice.

The Series 10 does charge faster than previous models, reaching 80% in 30 minutes with the included fast charger[2]. But daily charging is still required for most users.
