|Sources: Amazon, ManufacturerSamsung Galaxy Watch Ultra vs Amazfit Balance
Get the Samsung Galaxy Watch Ultra unless you want to save weight and money. With a whopping 100 hours of battery life in power-saving mode, it crushes the Amazfit Balance's 14-day typical use. However, if you're looking for a lightweight smartwatch, the Amazfit Balance at just 1.23oz is an easy choice for daily wear. In real-world use, the Galaxy Watch Ultra's robust design with 10ATM water resistance and LTE connectivity makes it ideal for outdoor activities and endurance sports. On the flip side, the Amazfit Balance's advanced wellness features, like body composition analysis, cater well to fitness enthusiasts who prioritize health metrics over ruggedness. The numbers say it all: 2.13oz vs 1.23oz means you’ll barely notice the Amazfit on your wrist, but the Samsung is built to withstand the elements.
