Battery Life Comparison: Multi-Day vs Daily Charging
Battery life is where Garmin and Apple Watch differ most dramatically, and it's often the deciding factor for many buyers.
Garmin Battery Life
Garmin watches are legendary for their battery longevity:
| Garmin Model | Smartwatch Mode | GPS Mode |
|---|---|---|
| Fenix 8 Solar | 29+ days | 48+ hours |
| Forerunner 970 | 14 days | 32 hours |
| Instinct 3 Solar | 24+ days | 26+ hours |
| Venu 3 | 14 days | 26 hours |
| Forerunner 165 | 11 days | 19 hours |
Solar models can extend battery life indefinitely with sufficient sun exposure. For multi-day adventures, ultra-marathons, or simply hating chargers, Garmin wins decisively.
Apple Watch Battery Life
Apple Watch requires daily charging regardless of model:
| Apple Watch Model | Battery Life | Fast Charge |
