A fresh report from Sammobile suggests Samsung plans to significantly upgrade the battery capacity in its upcoming Galaxy Watch Ultra 2. The rumored device would feature a rated battery of 784mAh, which the company might market as approximately 800mAh. This represents roughly a 35 percent increase over the original Ultra model that shipped with a 590mAh cell.
Rumors point to a significantly larger battery and more efficient processor for the upcoming smartwatch.
The upgraded power capacity arrives alongside a switch to Qualcomm's Snapdragon Wear Elite chipset. The new processor replaces older silicon in Samsung's premium smartwatch line and introduces a dedicated low-power neural processing unit for improved efficiency. The new design is expected to lower energy consumption without compromising the device's ability to handle health monitoring and wireless connections effectively.
Spec comparison
| Spec | Galaxy Watch Ultra 2 (Rumored) | Original Galaxy Watch Ultra |
|---|---|---|
| Battery Capacity | 784mAh (marketed ~800mAh) | 590mAh |
| Processor | Snapdragon Wear Elite chipset | Previous generation chip |
Samsung's rumored Galaxy Watch 9 series also receives battery bumps across its standard sizes. The smaller 40mm variant reportedly gets a 382mAh cell, which the company may market around 400mAh. The larger 44mm version is expected to house a 435mAh unit.
Sammobile's analysis indicates that the combined battery and chipset upgrades should deliver noticeably longer endurance compared to previous generations. The report emphasizes that the Snapdragon Wear Elite chip offers better power management through its smarter architecture and dedicated neural processing capabilities. These efficiency gains complement the raw capacity increase to extend daily usage between charges.
The Galaxy Watch Ultra 2 and Galaxy Watch 9 series currently sit in a pre-release phase with no official launch date or pricing from Samsung. Sammobile places the expected release window later in 2026, though this timeline remains unconfirmed by the manufacturer.
Samsung has not yet verified these specifications or release windows for its upcoming smartwatch lineup. The reported figures rely entirely on third-party analysis and industry speculation regarding component availability and product roadmaps.
