1. Navigate to Settings.

2. Select Battery & device care.

Disable features like 5G, Bluetooth, and location services when not in use to minimize power usage.

Some apps consume excessive resources even when running in the background, building up heat. Poorly optimized or outdated apps can also cause the processor to work harder than necessary.

To prevent this, regularly check battery usage:

1. Navigate to Settings.

2. Go to Battery and identify apps that drain power excessively.

3. Update or uninstall problematic apps.

4. Enable Adaptive Battery to restrict background activity for power-hungry applications.

If overheating persists despite optimization, residual data from past updates or device migration tools like Smart Switch may be interfering with system performance.

A factory reset can resolve deep-seated software issues by providing a fresh start. To do this:

1. Go to Settings.

2. Head to General management > Reset > Factory data reset.

3. After resetting, manually reinstall essential apps instead of restoring from a backup to prevent potential software conflicts.

Using your phone in extreme temperatures or direct sunlight can significantly contribute to overheating. Heat from the surroundings, combined with the device’s internal temperature, can cause performance throttling or even automatic shutdowns.

Avoid using your phone under direct sunlight for extended periods. If you’re outdoors, keep it in a shaded area. Additionally, remove thick or insulating cases when performing high-performance tasks to allow better heat dissipation.

Charging generates heat, and improper charging habits can worsen overheating issues. Using the phone while charging, especially for gaming or streaming, increases battery temperature significantly.

To prevent this, always use Samsung-approved chargers and cables for optimal charging efficiency. Avoid using your phone while it’s plugged in, and charge in a cool, well-ventilated area. Wireless charging also generates more heat, so opt for wired charging when possible.

Software updates often include performance optimizations and bug fixes that help manage power consumption and overheating. If your phone is heating up more than usual, it could be due to a firmware or app-related issue.

Check for updates regularly. To do this:
