Apple Watch Ultra 2 vs Garmin Fenix 8 AMOLED

Apple Watch Ultra 2

The Ultra 2 offers 36 hours of normal use and up to 72 hours in low-power mode, making it the only Apple Watch suitable for multi-day adventures.

• 36 hours normal use is transformative — finally an Apple Watch that lasts more than a day
• 72 hours in low-power mode makes multi-day hikes feasible without a charger
• Still can't match Garmin's weeks-long battery life for ultramarathon events

Garmin Fenix 8 AMOLED

Up to 29 days AMOLED, 48 days Solar MIP — in a league of its own.

• AMOLED model: up to 29 days in smartwatch mode — outlasts all Apple/Samsung watches by 10x+
• Solar MIP model: up to 48 days with always-on display
• 25% improved solar efficiency over Fenix 7 Solar
