|Sources: Amazon, ManufacturerSamsung Galaxy Watch Ultra vs Apple Watch Series 11
If battery life is your top priority, the Samsung Galaxy Watch Ultra crushes the Apple Watch Series 11 with a jaw-dropping 100 hours in power saving mode. That's enough to last through an entire weekend trip without needing a charge. In real-world usage, the Ultra's 3000 nits display brightness makes it easier to see outdoors, while the Apple Watch Series 11 offers a more compact build at just 1.07oz. The trade-off? You'll get a lighter watch, but it sacrifices battery longevity and display brilliance in exchange.
