The Garmin Enduro 3 features a significantly improved solar charging system that provides more than double the solar power of the previous Enduro 2 model[1]. This allows the Enduro 3 to achieve an impressive battery life of up to 320 hours in GPS mode with solar charging[1][8].
Here are the key improvements to the solar technology in the Enduro 3:
Larger and More Efficient Solar Ring
- The solar ring around the display has been enlarged and redesigned to be more efficient[1][2].- The ring is now black in color, making it less noticeable[2].
- This larger, more efficient ring allows Garmin to remove the semi-transparent solar panel that previously covered part of the screen, improving visibility[1][2].
Increased Solar Charging Capacity
- The new solar technology provides more than double the solar power of the previous Enduro 2 model[1].- In ideal conditions of 50,000 lux for 3 hours per day, the Enduro 3 can achieve up to 320 hours of battery life in GPS mode and up to 90 days in smartwatch mode[1][4].
- However, achieving the full 320 hours of GPS battery life may require the watch to be in 50,000 lux conditions for the entire activity, which is an idealized scenario[2].
Real-World Solar Charging Effectiveness
- In a real-world test of a 9-hour summer hike, the Enduro 3 gained around 1% of battery per hour in 50,000 lux conditions[6].- The solar charging is effective at keeping the battery level in smartwatch and expedition modes, but may not be able to fully recharge a depleted battery[3].
Overall, the new solar technology in the Enduro 3 is a significant improvement that provides industry-leading battery life, especially when combined with the watch's efficient power management[1][4]. However, the full 320-hour GPS battery life claim may be an idealized scenario, and real-world charging effectiveness will depend on the amount of sunlight exposure[2][6].
