Why Does My Phone Overheat While Charging?

Before jumping into fixes, let’s understand why your phone overheats while charging. Knowing the cause helps you choose the right solution faster.

Common Causes of Phone Overheating While Charging:

Cheap or incompatible charger. Third-party chargers that don’t match your phone’s power specifications deliver irregular voltage, generating excess heat.
Phone case trapping heat. Thick cases act like insulation and prevent heat from escaping while your phone charges.
Using your phone while charging. Gaming, streaming, or video calling while plugged in forces the processor and battery to work double-time, causing your phone to get hot when charging.
Software bugs or outdated system. Glitches can make your processor run overtime in the background, making your phone heat up while charging unnecessarily.
Degraded or old battery. Batteries older than 2–3 years lose efficiency and produce more heat during every charge cycle.
Hot environment. Charging your phone on a sunny windowsill, car dashboard, or near a heat source raises the temperature quickly.
Background apps syncing. Multiple apps updating, downloading, or syncing data simultaneously overwork the processor.
Damaged charging port or cable. Physical damage creates electrical resistance, which turns into heat.

How to Fix Phone Overheating While Charging (10 Step-by-Step Methods)

Here are 10 proven methods to fix phone overheating while charging. Start from Fix 1 and work your way down.

Fix 1: Remove Your Phone Case While Charging

A phone case is one of the top reasons your phone gets hot while charging. Thick, rugged, and leather cases are the worst offenders.

Unplug your phone from the charger.
Remove the case completely.
Let the phone cool for 2–3 minutes.
Plug it back in without the case.
Monitor the temperature during charging.

If this solves the phone overheating while charging problem, switch to a thinner case or one with heat-ventilation cutouts.

Fix 2: Switch to the Original Charger and Cable

Using the wrong charger is a leading cause of phone overheating while charging.

Stop using any third-party, gas-station, or dollar-store chargers immediately.
Locate the original charger and USB cable that came with your phone.
Plug in using only these original accessories.
Check if your phone still heats up while charging.

Lost your original charger? Buy a certified replacement directly from Apple, Samsung, Google, or your phone’s manufacturer. Never compromise on charger quality.

Fix 3: Close All Background Apps Before Charging

Background apps keep your processor busy and contribute to phone overheating while charging.

On Android:

Tap the recent apps button (square icon or swipe up and hold).
Swipe away all open apps individually.
Tap “Close All” if available.

On iPhone:

Swipe up from the bottom and pause (or double-click the Home button).
Swipe up on every app preview to close it.

Now plug in your charger. This alone can stop phone from overheating while charging in many cases.

Fix 4: Stop Using Your Phone While It Charges

This is the simplest and most overlooked fix for phone overheating while charging. Using your phone while plugged in forces the battery to charge and discharge simultaneously, creating significant heat.

Plug in your phone.
Put it down. Walk away.
Don’t play games, watch videos, browse social media, or make video calls.
Let it charge undisturbed.

If you must use your phone, unplug it first, use it, then plug it back in.

Fix 5: Charge in a Cool, Ventilated Area

Your charging environment plays a major role in whether your phone overheats while charging.

Move your phone away from windows, radiators, stoves, and direct sunlight.
Place it on a hard, flat surface — a table, desk, or countertop.
Never charge on a bed, pillow, couch, or blanket.
Ensure air can circulate freely around the device.

Soft surfaces trap heat underneath the phone and make the phone overheating while charging problem significantly worse.

Fix 6: Update Your Phone’s Software

Outdated software causes inefficient processing, which makes your phone hot when charging.

On Android:

Open Settings.
Scroll to System → Software Update.
Tap Check for Updates.
Download and install any available updates.

On iPhone:

Open Settings.
Tap General → Software Update.
Install any pending update.

Restart your phone after updating, then charge and monitor the temperature.

Fix 7: Turn Off Your Phone While Charging

Want the most effective way to stop phone from overheating while charging? Power it off completely.

Shut down your phone.
Connect the charger.
Let it charge while completely powered off.

This eliminates all processor activity, reduces heat dramatically, and actually speeds up charging time.

Fix 8: Disable Fast Charging Temporarily

Fast charging pushes more power into your battery in less time. This naturally generates more heat and can cause phone overheating while charging.

Open Settings.
Navigate to Battery or Battery and Device Care.
Find the Fast Charging option.
Toggle it off.
Charge normally and check the temperature.

If the overheating stops with fast charging disabled, your phone may have a fast-charging compatibility issue with your current charger or cable.

Fix 9: Clean Your Charging Port

A dirty charging port creates poor electrical contact and resistance heat, contributing to your phone getting hot while charging.

Power off your phone.
Use a wooden toothpick or soft anti-static brush.
Gently remove dust, lint, and debris from the port.
Do not use metal objects or blow compressed air directly inside.
Plug your charger back in and test.

Fix 10: Factory Reset (Last Resort)

If your phone is still overheating while charging after trying every fix above, a deep software issue may be the cause.

Back up all your data first — photos, contacts, messages, and files.
Go to Settings → System → Reset → Factory Reset.
Follow the on-screen instructions.
Set up your phone as new and test charging before restoring apps.

If phone overheating while charging continues even after a factory reset, the problem is hardware-related. Visit an authorized service center for battery inspection or replacement.

Common Mistakes to Avoid

Many people unknowingly make phone overheating while charging worse. Avoid these mistakes:

Gaming or streaming while charging. This is the number one cause of extreme phone overheating while charging.
Charging under a pillow or blanket overnight. This is a genuine fire hazard. Always charge on an open, hard surface.
Buying the cheapest charger you can find. Uncertified chargers lack voltage regulation and proper safety features.
Skipping software updates. Updates frequently include thermal management improvements that help prevent your phone from overheating while charging.
Stacking items on your phone while it charges. Books, clothes, or other devices block heat from escaping.
Ignoring temperature warnings. If your phone displays a heat warning, unplug it immediately and let it cool down completely before charging again.

Additional Tips to Prevent Phone Overheating While Charging

Follow these smart habits to prevent phone overheating while charging long-term:

Enable optimized or adaptive charging in your battery settings. This regulates charging speed overnight to reduce heat buildup.
Lower screen brightness while your phone charges. A bright display generates extra heat.
Turn on Airplane Mode during charging if you don’t need calls or texts. This shuts down cellular and Wi-Fi radios, reducing heat.
Avoid wireless charging in hot weather. Wireless chargers naturally produce more heat than wired charging.
Replace your battery every 2–3 years if you’re a heavy user. Degraded batteries are a major reason for phone overheating while charging.
Monitor your battery health regularly:
- iPhone: Settings → Battery → Battery Health & Charging
- Samsung: Settings → Battery and Device Care → Battery → Battery Health
Don’t charge to 100% every time. Charging between 20%–80% generates less heat and extends battery life.
Restart your phone weekly. A simple reboot clears background processes that may be making your phone hot when charging.
