One UI 7 Update Reportedly Causing Battery Drain on Samsung Galaxy Devices

Samsung’s long-awaited One UI 7 update is finally rolling out widely across Galaxy smartphones, including the latest Galaxy S24 series. However, users are now voicing concerns over increased battery drain following the update, particularly on flagship devices like the Galaxy Z Fold 6.

Galaxy Users Report Noticeable Drop in Battery Life

Multiple posts across Samsung Community forums, Reddit, and Android Police have highlighted that battery life on some devices has worsened since installing One UI 7. One Galaxy Z Fold 6 user claimed their end-of-day battery percentage dropped from around 45% to just 20%, indicating a significant change in power consumption.

Similar feedback has been echoed by users of other models in the Galaxy S24 and S23 lineups, although not all users are affected equally.

What’s Causing the Battery Drain?

While Samsung has not issued an official response, the potential cause remains uncertain. The large size of the One UI 7 update, which introduces new features and under-the-hood changes, may be taxing system resources. Interestingly, Samsung previously delayed the update, though the reasons were not disclosed—prompting speculation that power management issues might have been a factor.

Experts suggest that such behavior may stabilize in the days following the update, as the system recalibrates and background processes complete post-update optimizations.

Samsung Yet to Acknowledge the Issue

Despite the growing chatter, Samsung has not confirmed widespread battery issues, and the reports remain anecdotal. Given that One UI 7 has already reached millions of Galaxy users, the scale of the problem may be limited. Some users even reported better battery performance post-update, particularly on Galaxy S23 models.

Users experiencing battery drain are advised to:

• Monitor battery usage in settings to identify problematic apps

• Clear cache and perform a soft reset

• Wait for upcoming patches, as Samsung often addresses such bugs in monthly updates

What’s Next?

As the update continues its global rollout, Samsung is expected to issue a May security patch soon, which may include optimizations for power efficiency. Meanwhile, users should keep an eye on performance and report any unusual behavior through Samsung Members or official support channels.
