A new rumor indicates that the Galaxy Watch Ultra 2, Samsung’s next premium smart watch model, will come with a significant increase in battery capacity, around 35%. The expectation is that, combined with a more efficient processor, the device will significantly improve charge duration, one of the main weaknesses of the line so far.
The information was published by the SamMobile website and reveals that the top-of-the-line smartwatch will have a battery with a nominal capacity of 784 mAh, a value that should be marketed as 800 mAh.
This change represents a growth of just over 35% compared to the Ultra models of 2024 and 2025, easily surpassing the 590 mAh of previous generations.
With the new Snapdragon Wear Elite processor already confirmed for the accessory, analysts believe that the chip’s greater energy efficiency combined with the larger energy tank could bring a relevant advance in usage time — with the possibility of surpassing the three-day autonomy mark.
SamMobile also remembers that previous rumors also indicate battery upgrades for the entry-level Galaxy Watch 9. The 40 mm version should come with 400 mAh, an increase of 23% compared to the 325 mAh of the Watch 8 in the same size. The 44 mm one would bring 435 mAh, a more discreet increase of 10 mAh.

In any case, the full announcement of the new family of smartwatches should not be long in coming. The trio, which should also include a Classic model, is scheduled to be presented at the end of July, along with the foldable Galaxy Z Flip 8 and Galaxy Z Fold 8. New leaks are expected until then.
