the battery life of the Garmin Venu 3 appears to be inconsistent and may not live up to Garmin's advertised 14-day estimate in real-world usage:
- Some users report getting only 3-4 days of battery life, even without using the always-on display. One user saw a 20% drain per day with just one activity and some notifications.
- In controlled testing, one user got 8 days of battery life with 2 hours of GPS use, sleep tracking, and notifications. But this is still well below the 14-day claim.
- The battery life can vary significantly based on usage - enabling features like the always-on display, continuous heart rate monitoring, and PulseOx sensor can reduce battery life by 50% or more.
In comparison, the Garmin Forerunner 265 appears to have better battery life. According to the Tom's Guide review, the Forerunner 265 can last up to 15 days, which is longer than the Venu 3's 14-day estimate in ideal conditions.
The Venu 3 seems to struggle to reach the 14-day battery life claim, with many users reporting only 3-8 days of real-world usage. Unstable Bluetooth connections and firmware bugs may also be exacerbating the battery life issues for some Venu 3 owners. So the Forerunner 265 appears to have a more consistent and longer-lasting battery compared to the Venu 3 based on the available information.
