Owners of the Samsung Galaxy S24 and Samsung Galaxy S25 are increasingly reporting serious battery drain issues following Samsung’s April 2026 security update. What was expected to be a routine software patch has instead triggered complaints about overheating, unusually fast power loss, and poor standby battery performance across multiple Galaxy devices.
The reports have spread rapidly across Reddit, Samsung community forums, and tech publications, raising concerns that the latest update may contain a software bug affecting battery optimization.
Galaxy S24 and S25 Owners Say Battery Life Has Become “Terrible”
Several Galaxy users claim their phones began losing power abnormally soon after installing the April update. According to user reports, some devices now struggle to last a full day under normal use, while others experience dramatic drops in battery percentage within hours.
One Galaxy S24 Ultra owner on Samsung’s community forum said their device started draining “incredibly fast” immediately after the update was installed.
Users have also complained about:
- Excessive device heating
- Battery drain while idle
- Slower charging speeds
- Increased background activity
- Apps consuming abnormal power
The issue appears to affect both Exynos and Snapdragon-powered variants of the Galaxy S24 and S25 lineup.
What Caused the Battery Drain?
Samsung has not officially confirmed the root cause of the issue, but multiple reports suggest the April 2026 security patch may be responsible.
Some tech analysts believe the problem could be linked to:
- Background system processes
- Poor app optimization after the update
- Samsung Keyboard services
- Microsoft app compatibility issues
- One UI software bugs
A separate report indicated that Samsung moderators identified Samsung Keyboard as a potential battery-draining component on some Galaxy phones, and the company has reportedly started working on fixes.
Meanwhile, another report noted that the April patch may also be causing problems with Microsoft apps on Samsung devices, which could contribute to abnormal battery behavior.
The Problem Appears Widespread
A recent Android Authority survey suggested that a large number of affected users are experiencing the same battery problems after updating their phones.
The growing number of complaints across Reddit and Samsung forums suggests the issue is not isolated to a few devices. Users from different regions and carriers have reported similar symptoms, including overheating and severe standby battery drain.
Some frustrated owners even claim their premium flagship phones now require multiple charges per day after the update.
Temporary Fixes Users Are Trying
Although Samsung has not yet released an official patch, some users are attempting temporary workarounds to reduce battery drain.
Common troubleshooting steps include:
- Restarting the device
- Clearing cache partition
- Using battery saver mode
- Disabling unused background apps
- Updating Samsung system apps
- Wiping app cache data
- Checking battery usage statistics
However, reports suggest these fixes only provide limited improvement in many cases.
Samsung Has Yet to Release an Official Response
As of now, Samsung has not issued a formal statement confirming the battery drain issue or announcing a permanent solution.
The company may eventually release a hotfix or updated security patch if the complaints continue to grow. Samsung has previously addressed software-related battery issues through follow-up updates in earlier One UI versions.
Users are therefore advised to:
- Keep their devices updated
- Monitor battery usage
- Install future patches once available
- Report issues through the Samsung Members app
Should Galaxy Users Be Concerned?
Battery drain after major updates is not uncommon in smartphones, especially when system optimization processes continue running in the background after installation. However, the scale and severity of the current complaints suggest this may be more than normal post-update behavior.
For users relying heavily on their Galaxy S24 or S25 devices for work, gaming, or travel, the issue can become a major inconvenience.
Samsung’s next software update will likely be closely watched to see whether it resolves the growing battery concerns affecting its flagship smartphones.
