There are a variety of reasons your battery might not be lasting a full day. Most common reasons include:
- Low/poor cellular coverage (this causes the watch to have to work harder searching for signal and drains battery twice as fast),
- High usage of features like games, music, or above average time calling/texting, etc.
- High usage of Active Tracking (real time) or background location settings frequent updates on background location updates
- Screen brightness or always-on display settings
