How to Fix Galaxy S25 Overheating While Charging After Update

Galaxy S25 Overheating While Charging After Update usually means fast charging is generating too much heat, a charger or cable is unstable, background tasks are keeping the phone busy, or a recent software update changed battery management behavior. The fixes below focus on restoring safer charging temperatures and normal power behavior on the Galaxy S25 lineup.

Fix #1: Stop charging and let the phone cool first

Heat protection can slow or pause charging, so it is best to bring the temperature down before testing anything else.

Unplug the Galaxy S25 from the charger.
Remove the case if it traps heat.
Place the phone in a cool, shaded room for several minutes.
Do not put it in a fridge or freezer.

Fix #2: Switch to a known-good charger, cable, and power adapter

A weak or unstable charger can create extra heat while charging slowly or inconsistently.

Use an official Samsung charger or a trusted USB-C PD charger.
Try a different USB-C cable.
Avoid cheap adapters, hubs, or damaged accessories.
Test charging from a wall outlet instead of a laptop port.

Fix #3: Turn off Fast Charging temporarily and test again

If the issue started after the update, reducing charging speed can confirm whether the heat comes from fast-charge behavior.

Go to Settings > Battery.
Open Charging settings.
Turn off Fast charging for testing.
Charge again and watch the phone temperature.

Fix #4: Close heavy apps and restart the phone

Background apps, syncing, and media tasks can keep the processor hot during charging.

Close gaming, video, camera, and navigation apps.
Restart the Galaxy S25.
Charge the phone with the screen off.
Check whether overheating returns.

Fix #5: Install pending system and app updates

Samsung often ships quick fixes for charging and thermal bugs after major updates.

Go to Settings > Software update and install any available patch.
Update apps from the Play Store and Galaxy Store.
Restart the phone after updates finish.
Test charging again under normal conditions.

Fix #6: Reset settings if the heat started immediately after the update

A settings reset can clear corrupted power and charging preferences without deleting your files.

Go to Settings > General management > Reset.
Tap Reset all settings.
Re-enable only the settings you need.
If overheating still happens with multiple chargers, contact Samsung support.
