How to Fix Samsung Galaxy S24 Overheating After a One UI Update
We understand how frustrating it can be when your Samsung Galaxy S24 starts running hot immediately after a system update. The One UI refresh brings new features, but sometimes it also introduces background processes or misconfigured settings that push the processor harder than necessary. Before you consider a trip to the service center, know that many of these thermal spikes are resolvable with a few targeted steps. Our support team has compiled the most effective, verified methods to bring your device back to a comfortable operating temperature.
The update may have reenabled high-resolution rendering, aggressive transition animations, or system services that keep the CPU active in the background. Whatever the root cause, the good news is that most cases can be fixed without a full device replacement.
- Symptoms: Device feels warm to the touch, battery drains faster than usual, performance throttling, or automatic shutdowns after the update.
- Primary Fix: Wipe the cache partition and boot into Safe Mode to isolate problematic apps or services.
Below, we walk you through the three most reliable solutions, ranked by how quickly they resolve the issue and how deeply they address the underlying cause.
Step-by-Step Solutions to Fix the Issue
- 1. Enter Recovery Mode: Power off the device completely. Press and hold the Volume Up and Power buttons simultaneously until the Samsung logo appears, then release the Power button briefly while continuing to hold Volume Up until the recovery menu loads.
- 2. Wipe Cache Partition: Use the volume keys to navigate to Wipe cache partition and confirm with the Power button. Wait for the process to complete, then select Reboot system now.
- 3. Boot into Safe Mode: Once the device restarts, press and hold the Power menu, tap and hold Power off on the screen until the Safe Mode prompt appears, then tap Safe Mode. Observe thermal behavior for at least one hour.
- 4. Identify and Remove Rogue Apps: If the device remains cool in Safe Mode, uninstall recently updated or unfamiliar applications. Reboot normally and monitor for any return of heat.
Adjust One UI animation and rendering settings. Open the Settings menu, navigate to Display and disable Motion smoothness or set it to Standard instead of High. Additionally, go to Accessibility and turn off Reduce motion. These changes lower the graphical load on the processor, which can significantly reduce heat generation during idle or light usage. Restart the device after making these adjustments and observe if thermal levels normalize.
Factory reset as a last resort. If the above steps fail to stabilize the temperature, a factory reset may be necessary to eliminate deeply embedded software conflicts. Ensure your data is backed up to Samsung Cloud or a trusted PC first. Power the device off, then access Recovery Mode as described previously. This time, select Wipe data factory reset and confirm. The device will erase all user data and reinstall a clean version of One UI. After the reset, do not immediately restore all apps; instead, set up the phone as new for a day and monitor thermals. If the overheating stops, gradually reintroduce your accounts and applications, keeping an eye on any that trigger the heat again.
In many cases, using a low-quality or degraded charging cable can contribute to uneven power delivery, which compounds overheating after a software shift. Pairing your device with a certified premium charger and cable ensures stable power flow and reduces unnecessary thermal stress.
