How does the battery life of the Galaxy Watch 7 change with the always-on display enabled

Battery Life Overview with AOD Enabled

1. General Battery Performance: The Galaxy Watch 7 can last between 30 to 33 hours on a single charge with regular use, which includes sleep tracking and the AOD enabled. This is an improvement over its predecessor, the Galaxy Watch 6[6].

2. Impact of Always-On Display:
- Enabling AOD contributes to battery drain because it requires the display to remain active, lighting up pixels continuously. While it does not cause an extreme reduction in battery life, it is enough to affect overall performance[1][4].
- Some users have reported drastic reductions in battery life when AOD is active, with instances of the watch draining to zero in as little as 10 to 12 hours under certain conditions[5].

3. User Experiences: Many users express dissatisfaction with the battery life when AOD is enabled, often needing to recharge their watches daily instead of achieving the expected multi-day usage[5][6].

4. Power Saving Options: To extend battery life, users can disable AOD or switch to power-saving modes. For example, turning off AOD can significantly improve battery longevity, allowing for better performance over a longer period without charging[1][4].

In summary, while the Galaxy Watch 7 offers advanced features and improved battery performance compared to previous models, enabling the Always-On Display can lead to noticeable decreases in battery life, prompting many users to seek alternatives for longer usage times.
