Why Your Smartphone Overheats & 10 Easy Ways to Fix It (2025)
Does your phone suddenly get hot even when you’re not using it heavily? In 2025, smartphone overheating remains a common problem for users in Nigeria and beyond. Whether you're using an Android device like Tecno, Infinix, Samsung or even an iPhone, overheating can slow down your phone, damage your battery, or cause it to shut down unexpectedly.
This article explains why your phone heats up and offers 10 smart solutions to fix it fast. Most of these fixes are free and can protect your phone’s lifespan.
What Causes Phone Overheating?
Phones are built to operate within a safe temperature range. When that range is exceeded, your device may lag, freeze, or overheat. Common causes include:
- Too many background apps
- Heavy gaming or video streaming
- Charging with fake or poor-quality chargers
- Exposure to direct heat or sun
- Malware or outdated software
- Faulty battery or processor
10 Easy Ways to Fix Phone Overheating
1. Close Background Apps
Apps running silently can use RAM and CPU, causing heat. Clear them manually or use tools like Phone Master or Device Care.
2. Don’t Use While Charging
Charging alone heats up the battery. Using the phone at the same time doubles the stress. Let it charge undisturbed.
3. Use Original Chargers Only
Fake chargers can ruin your battery and generate unsafe heat. Learn how to detect fake chargers.
4. Reduce Screen Brightness
High brightness increases heat. Lower it manually or enable auto-brightness to conserve power and keep the phone cooler.
5. Activate Battery Saver Mode
Battery Saver restricts background usage and lowers performance load. On Android: Settings > Battery > Battery Saver.
6. Remove Your Phone Case
Some phone cases trap heat. Remove it temporarily when charging or playing games to improve ventilation.

7. Keep Your Apps Updated
Outdated apps may contain bugs that cause heat buildup. Update apps and system firmware regularly to ensure efficiency.
8. Restart Your Phone Regularly
A fresh restart clears memory and stops overheating apps. Try restarting your phone every 2–3 days.
9. Avoid Direct Sunlight
Phones exposed to heat sources or sunlight heat up quickly. Keep your device in shade or a bag when outdoors.
10. Avoid Too Much Multitasking
Running camera, music, browser, and games all at once causes overheating. Use apps one at a time, especially on low-RAM phones.
Bonus Tip: Install a Cooling App
Apps like Cooler Master or Device Cooler monitor temperature and close heat-generating apps. Just avoid apps that flood your screen with ads.
Why You Shouldn’t Ignore Overheating
If your phone keeps overheating, here’s what can happen:
- Battery drains faster
- Lagging apps and poor performance
- Permanent battery or chip damage
- Random shutdowns or reboots
Most heat damage builds up over time — until your phone dies or the battery swells.
