Samsung Electronics is reportedly developing the Galaxy Watch Ultra 2 with a significantly larger battery to improve device endurance [1, 2].

This upgrade targets the most consistent criticism of Samsung's wearable line. By increasing power capacity, the company aims to close the gap with competitors and satisfy users who find current battery life insufficient [2, 3].

Leaks indicate the Galaxy Watch Ultra 2 will ship with a 500 mAh battery [3]. This represents a sizable jump from the 300 mAh cell found in the current Galaxy Watch Ultra [3]. Such an increase would address a long-standing hardware limitation that has hindered the brand's appeal among power users.

"The biggest gripe with Samsung’s wearables has always been battery life," James Trew of Trusted Reviews said [2].

There is conflicting information regarding the device's release schedule. Some reports expect the watch to launch at Samsung’s summer Unpacked event in 2024 [1, 2], while other sources suggest it could arrive in early 2025 [1, 3]. The announcement is expected to take place at a global Unpacked event streamed online [1, 2].

"The Ultra 2 could finally give the Apple Watch Ultra a run for its money on endurance," Andrew E. of Digital Trends said [3].

Samsung has not officially confirmed the specifications or the launch date. However, the focus on battery capacity suggests a strategic shift toward the high-end endurance market, a segment currently dominated by ruggedized alternatives from Apple and Garmin [2, 3].

"The biggest gripe with Samsung’s wearables has always been battery life."

The potential jump to a 500 mAh battery indicates that Samsung is prioritizing raw hardware capacity to solve a software and efficiency deficit. If the rumors are accurate, this shift moves the Galaxy Watch Ultra from a standard smartwatch into a true endurance category, directly challenging the Apple Watch Ultra's market share by removing the 'battery anxiety' that has historically plagued Samsung's Wear OS implementation.
