Apple Watch Series 11 vs Samsung Galaxy Watch Ultra

Apple Watch Series 11

The headlining upgrade: 24-hour battery finally makes all-day + sleep tracking viable.

• 24-hour battery life up from 18 hours — a 33% improvement that changes the daily experience
• Fast charging preserved — 0 to 80% in about 45 minutes
• Still requires daily charging unlike Garmin multi-day watches

Samsung Galaxy Watch Ultra

Best battery life in Samsung's smartwatch lineup, though still behind Garmin.

• I consistently got 2.5-3 days of normal use — a huge improvement over the Galaxy Watch 6 series.
• The power-saving mode stretching to 60 hours is useful for multi-day hikes, but you lose most smart features.
