Some Galaxy S25 Ultra owners are reporting a noticeable surge in battery drain following the installation of Samsung’s latest One UI beta update. The complaints, which have surfaced across Samsung’s community forums and platforms like Reddit, suggest that the Samsung Galaxy S25 Ultra battery life has taken a significant hit after the update rolled out.
Multiple users report that their devices are losing charge at an unusually rapid pace during regular use. One user described their battery dropping from 60% to 45% in under an hour while doing nothing more than light browsing and messaging — a pattern they said was not present before the update. Reports of the Galaxy S25 Ultra battery drain issue point to consistent behavior across different usage scenarios, including standby.
The Galaxy S25 Ultra latest update problem does not appear to be isolated to a single device. Galaxy S25+ users are also chiming in with similar experiences, noting faster-than-normal discharge after applying the same beta software. The number of voices echoing the concern suggests this may be a broader One UI beta battery drain issue rather than a handful of isolated cases.
Many users are drawing a direct comparison between One UI Beta 7 and its predecessor. According to community posts, Beta 6 did not produce the same level of battery concern, and some users say performance — including app responsiveness and thermal behavior — also feels slightly degraded on Beta 7. The Samsung beta update battery drain appears to be the most common complaint, but it is often mentioned alongside general smoothness issues.
Samsung has not publicly acknowledged the Galaxy S25 Ultra battery issue or confirmed any findings related to the beta software issue at the time of writing.
Users experiencing the problem are encouraged to submit detailed feedback through the Samsung Members app, which remains the official channel for reporting bugs during beta testing. Samsung typically uses this data to address issues before a stable release. As with any beta software, some instability is expected, and it remains to be seen whether a fix will be included in a future update.
