Samsung’s next rugged smartwatch could be getting one of the biggest battery upgrades we’ve seen on a Wear OS device.
According to a new report, the Galaxy Watch Ultra 2 will feature a battery with a rated capacity of 784mAh. This would likely be marketed as an 800mAh cell when the watch launches. If accurate, that would represent a jump of more than 30% over the current Galaxy Watch Ultra’s already sizeable 590mAh battery.
Battery life has become one of the biggest battlegrounds for smartwatch makers. This is especially true in the Wear OS world, where many devices still struggle to make it comfortably through multiple days of use. That’s what makes this rumoured upgrade stand out.
For comparison, reports suggest Samsung will equip the upcoming 40mm Galaxy Watch 9 with a 382mAh battery. Meanwhile, Google’s latest Pixel Watch 4 models pack 325mAh and 455mAh cells, depending on size. On paper at least, the Galaxy Watch Ultra 2 would offer almost double the battery capacity of many mainstream Wear OS watches.
Of course, battery size doesn’t automatically translate into battery life. Factors such as display efficiency, software optimisation and processor performance all play a major role. However, the original Galaxy Watch Ultra already ranks among the better-performing Wear OS watches for endurance. As a result, a larger battery could make its successor even more appealing for users who prioritise longevity over slim designs.
The report also suggests Samsung will pair the new watch with Qualcomm’s Snapdragon Wear Elite platform. This platform will power several upcoming flagship smartwatches. If the chip delivers meaningful efficiency gains alongside the larger battery, Samsung could be looking at a substantial real-world improvement.
It’s also shaping up to be the first major refresh of the Ultra line since the original model launched. While last year’s update focused largely on refinements, the Galaxy Watch Ultra 2 is beginning to look like a more significant upgrade. This could be especially true if battery life becomes its headline feature.
Samsung is widely expected to unveil the Galaxy Watch Ultra 2 in July alongside the Galaxy Z Fold 8.
