Written by How to Fix iPhone Overheating While Charging – (Easy & Safe Tips) 2026. iPhone overheating while charging is a common problem faced by many users. If your iPhone feels unusually hot when plugged in, it can be worrying—not only for comfort but also for battery health and device safety. The good news is that most overheating issues are easy to fix once you understand the causes.
How to Fix iPhone Overheating While Charging (Easy & Safe Tips)
In this detailed guide, you’ll learn why your iPhone overheats while charging, easy and safe fixes, and long-term prevention tips to keep your iPhone cool and healthy.
Why Does an iPhone Overheat While Charging?
Before fixing the problem, it’s important to understand what causes overheating. An iPhone naturally warms up during charging, but excessive heat usually points to an issue.
Common Reasons for iPhone Overheating
- Using a low-quality or fake charger
- Charging while using heavy apps (games, video streaming)
- Hot room temperature or direct sunlight
- Background apps consuming power
- iOS software bugs
- Battery health degradation
- Charging with a thick phone case
- Using the phone while fast charging
Understanding the root cause helps you apply the correct solution instead of guessing.
Is iPhone Overheating While Charging Dangerous?
Occasional warmth is normal, but frequent overheating is not.
Potential Risks of Overheating
- Faster battery degradation
- Reduced charging speed
- Automatic charging pause
- Performance throttling
- Shortened device lifespan
Apple includes safety systems that stop charging if temperatures get too high, but relying on these protections repeatedly is not ideal.
How to Fix iPhone Overheating While Charging (Easy & Safe Tips)
1. Use Only Original or Certified Chargers
One of the most common causes of overheating is using cheap or non-certified charging accessories.
What to Do:
- Use Apple original chargers or MFi-certified cables
- Avoid damaged or frayed charging cables
- Replace old chargers that heat up during use
Low-quality chargers can send unstable power, forcing the battery to work harder and generate excess heat.

2. Remove the Phone Case While Charging
Some phone cases trap heat, especially thick or rugged cases.
Why This Helps:
- Improves heat dissipation
- Prevents heat buildup around the battery
- Allows faster and safer charging
Tip: If your iPhone feels hot, remove the case and place it on a cool surface while charging.
3. Stop Using the iPhone While Charging
Using your iPhone during charging—especially for gaming or streaming—forces the device to charge and discharge at the same time.
Apps That Increase Heat:
- Games with high graphics
- Video streaming apps
- GPS and navigation apps
- Video calls
Best Practice: Let your iPhone charge without active use for faster and cooler charging.
4. Turn On Airplane Mode While Charging
Airplane Mode reduces power consumption by disabling wireless connections.
Benefits:
- Reduces CPU workload
- Limits background data usage
- Speeds up charging
- Lowers heat generation
You don’t need to keep it on all the time, but it’s helpful if your iPhone heats up often while charging.
5. Avoid Charging in Hot Environments
Environmental temperature plays a major role in overheating.
Avoid:
- Charging in direct sunlight
- Leaving your phone on a bed, pillow, or sofa
- Charging inside a hot car
Ideal Charging Conditions:
- Cool, well-ventilated room
- Flat surface like a table or desk
Apple recommends operating temperatures between 0° and 35°C (32° to 95°F).
6. Close Background Apps
Apps running in the background can cause unnecessary CPU usage.
How to Close Apps:
- Swipe up from the bottom (or double-press Home button)
- Swipe away unused apps
- Focus on charging with minimal activity
This reduces internal processing and keeps the device cooler.

7. Update iOS to the Latest Version
Software bugs can cause overheating, especially after major updates.
Why Updates Matter:
- Bug fixes
- Improved power management
- Battery optimization
How to Update:
- Go to Settings > General > Software Update
- Install the latest stable iOS version
If overheating started after an update, Apple often fixes it in the next patch.
8. Disable Fast Charging (When Possible)
Fast charging generates more heat than standard charging.
Tips:
- Use a lower-watt charger if overheating is frequent
- Charge slowly overnight
- Avoid fast charging when the phone is already warm
While fast charging is safe, frequent overheating can impact long-term battery health.
9. Check Battery Health
An aging battery can overheat more easily.
How to Check Battery Health:
- Go to Settings > Battery > Battery Health & Charging
- Look at Maximum Capacity
If capacity is below 80%, overheating may occur more often, and battery replacement could help.
10. Reset iPhone Settings (If Needed)
If nothing works, system settings might be causing the issue.
Safe Reset Option:
- Go to Settings > General > Transfer or Reset iPhone
- Tap Reset > Reset All Settings
This won’t delete your data but resets Wi-Fi, display, and system preferences.
What NOT to Do When iPhone Overheats
Avoid these mistakes:
- ❌ Putting the phone in a fridge or freezer
- ❌ Using third-party cooling accessories
- ❌ Charging with damaged cables
- ❌ Ignoring frequent overheating
Sudden temperature changes can damage internal components.
How to Prevent iPhone Overheating in the Future
Best Long-Term Practices
- Use original charging accessories
- Avoid full gaming sessions while charging
- Keep iOS updated
- Maintain good battery health
- Charge in cool environments
- Remove case during long charging sessions
Consistent habits can significantly reduce overheating problems.
When Should You Contact Apple Support?
You should seek professional help if:
- iPhone overheats even when not charging
- Device shuts down frequently due to heat
- Battery health drops rapidly
- You see temperature warning messages often
This may indicate a hardware or battery issue that needs repair.
