From what 5 owners of the Amazfit Balance Ultra reported between July and August 2026. Earlier generations are not counted.
Very few owners have posted about the Balance Ultra yet, so this is a handful of people, early adopters coming from Balance 2 or Balance 3. The owner who compared it directly with Balance 3 liked the Ultra more than they expected: it sat better on the wrist, the crown stopped digging in, and the titanium looked less flashy.
The complaints are specific rather than general. One owner saw a weaker GPS track in forest, another says treadmill pace runs backwards as speed goes up, and a third has a cadence assistant that never makes a sound, on two separate watches. A torn strap within a month and buttons that lock along with the screen round it out.
It makes sense for someone who already likes the Balance line and wants the longest battery and a titanium case. Anyone who runs mostly in woods or does treadmill speed work should check how those two hold up before relying on it, since those are the areas owners have flagged.
