Samsung's Galaxy Watch battery drains after update as One UI 9 beta for S25 appears

Users of Samsung Galaxy Watch models—including Watch6, Watch7 and Watch8—have reported rapid battery loss after a recent software update. Battery levels can drop from around 40 % to single‑digit percentages within minutes, prompting speculation that a software bug, possibly linked to a July security patch, is responsible. Affected owners have tried clearing the watch cache and, in some cases, performing factory resets, but results vary.

Separately, Samsung has placed a test build of One UI 9, based on Android 17, on a South Korean server for the upcoming Galaxy S25 series. The build, which includes features such as My FanCam, Horizontal Lock, and updated Bixby capabilities, suggests a public beta could be released in the next few days, initially in South Korea before expanding to other markets. Samsung has not confirmed the rollout schedule for other countries, including Slovakia.

Both stories illustrate Samsung's ongoing software development cycle, with one highlighting a consumer‑facing issue and the other previewing the next major UI update for its flagship phones.
