The battery life comparison between GPS Only mode and GPS + GLONASS mode on Garmin devices shows notable differences in performance:
Battery Life Comparison
1. GPS Only Mode:
- Typically provides longer battery life. For example, some Garmin models can last up to 33 to 42 hours in GPS Only mode, depending on the specific device and settings used[1][4].
2. GPS + GLONASS Mode:
- While this mode enhances accuracy by utilizing additional satellite systems, it generally consumes more battery power than GPS Only mode. As a result, battery life is reduced, often lasting around 19 to 20 hours during active use[2][5].
Summary of Key Points
- GPS Only Mode is more battery-efficient, making it suitable for longer activities where extended tracking is necessary.
- GPS + GLONASS Mode improves accuracy, especially in challenging environments, but at the cost of shorter battery life.
In conclusion, if maximizing battery life is a priority for long activities, using GPS Only mode is recommended. However, for improved accuracy in complex environments, GPS + GLONASS can be beneficial, albeit with reduced battery performance.
