The Garmin Fenix 8 Solar model indeed has a better battery life compared to the AMOLED model.
Battery Life Comparison
- Fenix 8 Solar:
- Up to 30 days in smartwatch mode.
- Up to 48 days with solar charging, assuming ample sunlight exposure.
- Fenix 8 (AMOLED):
- Up to 29 days in smartwatch mode.
- The AMOLED model's battery life is slightly less, with around 10 days when using the always-on display feature[1][3][4].
Additional Insights
The Fenix 8 Solar features a memory-in-pixel (MIP) display, which is less power-intensive than the AMOLED display used in the Fenix 8. This difference in display technology contributes to the longer battery life of the Solar version. Furthermore, both models have various power-saving modes, but the inherent efficiency of the Solar model allows it to outperform the AMOLED version in terms of overall battery longevity[2][3][4].
In summary, if battery life is a critical factor for your usage, the Fenix 8 Solar model is the superior choice.
