Garmin Fenix 8 AMOLED vs Google Pixel Watch 3

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

Google Pixel Watch 3

Improved but still not multi-day — expect daily charging.

• I averaged about 26-28 hours on a charge with always-on display — better than Pixel Watch 2 but you're still charging nightly.
• Fast charging is a lifesaver — 30 minutes gets you back to 50%, which is enough for a full day.
