Why Your Phone Says “Charging Stopped Because It’s Overheating”: Causes & Fixes

Table of Contents

Introduction

Modern smartphones are designed to protect themselves from damage, and one common warning message users encounter is “Charging stopped because it’s overheating”. This alert indicates your device’s internal temperature has risen to unsafe levels, prompting the system to halt charging to prevent hardware failure. While frustrating, this safety mechanism is critical for preserving battery health and avoiding risks like explosions or permanent component damage. In this guide, we’ll explore the root causes of overheating during charging, actionable solutions, and preventive strategies to keep your device running smoothly.

Why Do Phones Overheat While Charging?

1. Fast Charging Technology

Fast chargers deliver power at higher voltages (e.g., 18W, 30W, or 65W) to reduce charging times. While convenient, this process generates significant heat. Older or low-quality batteries may struggle to dissipate this heat efficiently, leading to overheating warnings.

2. Background App Activity

Apps running in the background—especially resource-heavy ones like gaming, video streaming, or GPS navigation—increase CPU usage. When combined with charging, this dual strain can push the device’s temperature beyond safe limits.

3. Poor Ventilation

Using your phone while it’s charging under a pillow, in a case, or on a soft surface blocks airflow. Without proper cooling, heat accumulates rapidly.

4. Faulty Charging Equipment

Damaged cables, non-certified chargers, or loose ports can cause irregular power flow, leading to erratic heating.

5. Outdated Software

Bugs in outdated OS versions may mismanage power delivery, causing the device to overheat during charging.

How to Fix “Charging Stopped Due to Overheating”

1. Remove the Case While Charging

Phone cases, especially rubber or thick ones, trap heat. Charging your device without a case allows for better heat dissipation.

2. Use Original or Certified Chargers

Counterfeit chargers often lack safety mechanisms to regulate power output. Always use MFi-certified (for iPhones) or OEM chargers for Android devices.

3. Close Unnecessary Apps

Double-tap the home screen (iOS) or use the app switcher (Android) to close background apps. This reduces CPU/GPU load and lowers internal temperature.

4. Avoid Extreme Temperatures

Never charge your phone in direct sunlight, near heaters, or in hot cars. Ambient heat exacerbates overheating issues.

5. Update Your Software

Manufacturers frequently release updates with thermal management improvements. Check for OS updates in Settings.

6. Enable Battery Saver Mode

This mode limits background activity and reduces screen brightness, easing the strain on your device during charging.

When to Worry: Hardware vs. Software Issues

Software Fixes to Try First

Reset Battery Stats (Android):
Go to Settings > Battery > Battery Usage > More Options > Reset Battery Stats.
Calibrate the Battery (iOS):
Drain your battery to 0%, charge it to 100% uninterrupted, then restart the device.

Hardware Red Flags

If overheating persists despite software fixes, your device may have:

A swollen or degraded lithium-ion battery.
A damaged charging port (e.g., bent pins, corrosion).
A faulty power management IC (PMIC).

Solution: Contact a certified repair technician. DIY repairs can void warranties or cause further damage.

Preventative Measures for Long-Term Health

1. Optimize Charging Habits

Charge your phone between 20%–80% to reduce battery stress.
Avoid overnight charging, which keeps the battery at 100% for extended periods.

2. Invest in a Cooling Pad

Gaming accessories like cooling pads (with fans or heat sinks) can mitigate heat during intensive use.

3. Monitor Battery Health

iOS: Settings > Battery > Battery Health & Charging.
Android: Use apps like AccuBattery to track temperature and capacity.

4. Replace Aging Batteries

Most smartphone batteries last 2–3 years before capacity drops below 80%. Replace them promptly to avoid overheating.

Conclusion

The “charging stopped because it’s overheating” warning is a safeguard, not a nuisance. By addressing underlying causes like fast charging, background apps, and poor ventilation, you can resolve most issues. For persistent problems, professional diagnostics are essential. Prioritizing safe charging habits will extend your device’s lifespan and prevent costly repairs.
