Samsung’s latest One UI 7 update, based on Android 15, rolled out earlier this year with the launch of the Galaxy S25 series. While the software update brings several new features and improvements, it hasn’t been a smooth ride for everyone. Many users are now reporting battery drain issues after installing One UI 7 on their devices—including both new and older Galaxy models.
Rollout
The One UI 7 update first arrived with the Galaxy S25 series during Samsung’s Galaxy Unpacked event in January. It later made its way to older devices, including the Galaxy S24 and Galaxy S23 series, starting from April 7. While most users were looking forward to improved performance and features, some are now facing unexpected battery problems.
Affected Devices
According to user reports on Reddit, Samsung’s community forums, and social media platform X (formerly Twitter), the battery drain issue seems to affect several Galaxy devices. These include:
- Galaxy S24 series
- Galaxy S23 series
- Galaxy Z Fold 6
- Even some Galaxy S25 series units
A Galaxy Z Fold 6 owner said their device now ends the day at 20–25 percent battery, compared to 45–50 percent before the update. A Galaxy S24 Ultra user mentioned they barely get six hours of screen-on time, a noticeable drop from what they were getting prior to installing One UI 7.
User Feedback
Most of the complaints suggest a steep decline in battery performance immediately after updating to One UI 7. However, it’s worth pointing out that this isn’t uncommon. After major Android updates, phones usually go through a phase of system optimisation, which can temporarily increase power consumption. Apps get reindexed, settings recalibrate, and background services settle into new routines.
Temporary Fixes
Until Samsung officially responds or rolls out a fix, some users have suggested a few workarounds that might help:
- Clear the cache partition via recovery mode
- Give the phone a few days to adapt post-update
- Turn off unnecessary background apps
- Reduce display refresh rate or brightness
- Perform a factory reset (as a last resort)
While these may not solve the issue completely, they can help reduce excessive battery drain temporarily.
Samsung’s Response
As of now, Samsung has not issued an official statement regarding the battery drain issue. However, the company is likely aware of the complaints and may address the problem in the upcoming May 2025 software patch. Given the number of users affected across various Galaxy models, a fix could be high on Samsung’s priority list.
Here’s a quick look at what’s been reported:
| Model Affected | User Complaints |
|---|---|
| Galaxy S24 Ultra | Reduced screen-on time to under 6 hours |
| Galaxy S23 Series | Faster battery drain after update |
| Galaxy Z Fold 6 | Battery drops below 25% by end of day |
| Galaxy S25 Series | Some users report similar issues post-update |
What’s Next?
Until an official update rolls out, the best course of action might be to let the system stabilise. Background optimisation processes can take a couple of days to complete. If the battery issues persist beyond that, trying a clean installation or visiting a Samsung service center might be necessary.
