[Battery Review] Amazfit Active 2 Premium: Detailed Consumption Tracking & Analysis
I have conducted a systematic monitoring of the Amazfit Active 2 Premium battery performance. Below is the analytical breakdown of the recorded data, including daily drain rates and aggregated metrics.
I have meticulously tracked the battery performance of my Amazfit Active 2 Premium over 6 complete discharge cycles (43 days total). My goal was to understand the impact of specific activities (GPS, Strength training, "Libero" sessions) and night-time drain.
Below is the raw data log and the subsequent analytical breakdown.

2. Statistical Analysis & Key Findings
Average Consumption Rates
- Overall Daily Average: ~12.1% per 24 hours.
- Idle Days (No recorded workouts): ~9.4% per 24 hours.
- Workout Days: ~14.8% per 24 hours.
Activity Impact
- Libero (Freestyle) Sessions: On average, a session of 70-90 minutes causes a specific drop of 7% to 12%.
- GPS Usage: A single 35-minute run (Day 4) resulted in a 7% drop, highlighting the significant impact of the GPS module compared to indoor activities.
- Strength Training: Approximately 7% drain for 60-65 minutes of active tracking.
Critical Observations
- Night-time Drain: Consistently accounts for 4% to 7% of the total daily consumption.
- Consistency: The device shows a very stable discharge pattern. Between Cycles 2 and 6, the final remaining battery consistently hit the 12% - 15% range after ~7 days of use.
- The "17% Spike": There is a recurring maximum drain of 17% specifically on Mondays (Days 6, 13, 20, 27, 34, 42).
3. Conclusion
The Amazfit Active 2 Premium provides approximately 7 to 8 days of autonomy under moderate-to-heavy usage. The most significant drain factors are GPS and baseline night-time consumption.
Additionally, I observed no significant impact from different watch faces. Note that I never used the Always-on Display (AOD), relying instead on the "raise to wake" gesture, and I configured the display to turn off automatically based on my sleep schedule.
I hope this monitoring proves useful to anyone trying to determine the real-world battery consumption of this watch under average use, including 2 to 4 weekly workouts.
Please apologize for any grammatical errors in this post; I used Google Gemini to translate my data and observations from Italian.
