Apple Watch Ultra 2 vs Google Pixel Watch 3

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

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.
