Samsung Galaxy Watch Ultra Battery Life, Energy Score, Sleep & AGE Index
Science & Technology
Introduction
Initial Impressions on Battery Life
I've been using the Samsung Galaxy Watch Ultra for four days, and I wanted to share my initial impressions on its battery life. It's essential to note that Samsung devices, including their watches, adapt to your usage patterns over a few days. During this "calibration" phase, the device learns how you use it to optimize battery performance.
Samsung claims the Galaxy Watch Ultra can achieve up to 48 hours in Power Saving Exercise Mode and 100 hours in Power Saving Mode. After calibration, I'm getting about 24-26 hours of battery life, which is disappointing given the high expectations set by Samsung.
Current Settings and Usage
Even with moderate usage and various health tracking settings enabled, including SPo2 (blood oxygen) monitoring and skin temperature measurements during sleep, the battery life still falls short of expectations.
I previously used Garmin and Huawei smartwatches, which required charging every 5-10 days. For the Galaxy Watch Ultra, without always-on display and other battery-saving options, the battery depletes faster. For instance, listening to two songs on Spotify drained 4% of the battery.
Sleep Tracking and Health Features
Despite short battery life, the sleep tracking and health features are impressive. The Samsung Health app provides detailed information on sleep scores, cycles, and recovery metrics. The new Energy Score feature combines sleep and activity data to give a comprehensive view of your overall health.
Sleep Tracking Breakdown
- Sleep Score: For instance, I had a sleep score of 97, indicating excellent sleep.
- Sleep Stages: Displays REM, light, and deep sleep stages.
- Sleep Factors: Analyzes sleep time, physical and mental recovery, restfulness, etc.
Energy Score and AGE Index
The Energy Score is a new addition, taking various factors like sleep time and activity to provide an overall energy metric. The AGE Index measures advanced glycation end-products (AGEs), providing insights into your metabolic health influenced by diet and lifestyle.
Battery Life Optimization Prospects
Currently, the battery performance is underwhelming. Even with reduced settings like turning off Always-On Display and manual stress measurement, it lasts about 24-25 hours. Using Power Saving modes might extend battery life, but it limits many features, making the watch less functional.
Future updates and further calibration might improve battery efficiency, especially considering the 3 nm processor's energy-efficient design. But as of now, the battery life still needs improvement to meet user expectations fully.
Conclusion
For now, the Galaxy Watch Ultra offers a rich set of health and sleep tracking features but falls short in terms of battery performance. Once the battery life improves, it could become a strong contender among premium smartwatches.
