Amazfit Balance 2 vs Samsung Galaxy Watch Ultra
Size, specs & wrist fit compared
Which one fits you
Both need much the same wrist: neither overhangs from 17 cm (6.7 in) round, and both are in their sweet spot around 18–20 cm. Wrist size will not decide between these two.
What else differs
- Battery: 21 days for the Amazfit Balance 2 against 4 days for the Samsung Galaxy Watch Ultra in everyday use.
- Only the Samsung Galaxy Watch Ultra has an ECG app and an LTE version.
The Amazfit Balance 2 and Samsung Galaxy Watch Ultra share a near-identical 47.4mm case, so on the wrist the difference is thickness and weight.
Among the 60 smartwatches 47mm across that we hold thickness for, the Samsung Galaxy Watch Ultra is thinner than 87%, so it wears flatter than its width suggests.
The Amazfit Balance 2 is 0.2mm thicker and 17.5g lighter than the Samsung Galaxy Watch Ultra.
