Amazfit Balance Ultra vs Balance 3 specs comparison
The Balance Ultra is less of a completely different watch and more of a higher-end version of the Balance 3. Both offer the same 1.5-inch sapphire AMOLED display, 10 ATM rating, extensive mapping and Zepp OS 6, but the Ultra stretches typical battery life from 21 to 30 days, adds a fifth button and pushes GPS runtime to 50 hours. Balance 3 offers most of the experience for less; Ultra is for those who want maximum endurance and the higher-end finish.
