Overheating of iPhone or Charging Pad Causes Charging Issues

Picture this: your iPhone is about to die; you plug it in to charge, but then nothing. There is no comforting lightning bolt icon, no satisfying ‘beep’ – just a stubbornly low battery and an overheating phone.

This issue often arises when your iPhone or its charging pad gets too hot, causing the device to activate its built-in protections to prevent damage. This includes slowing or stopping the charging process, with a “Charging On Hold” notification popping up until the phone returns to a normal temperature.

So, how can you prevent your iPhone from overheating and ensure it charges when needed? Let’s dive in and find the answers together.

Understanding the Issue

All electronic devices, including iPhones, have an optimal operating temperature range. Apple Support says the ideal ambient temperature for iOS and iPadOS devices is between 0º and 35º C (32º to 95º F). Exposing your iPhone to temperatures outside this range can change the device’s behavior to regulate its temperature.

When an iPhone or its charging pad overheats, the device’s built-in protections are triggered to prevent damage. This includes slowing or stopping charging, dimming the display, disabling the camera flash, or reducing the performance of graphics-intensive apps. If your iPhone is too hot while charging, the system might display the “Charging On Hold” notification. Your iPhone will resume charging once it returns to its normal temperature.

Moreover, conditions like leaving your device in a car on a hot day, exposing it to direct sunlight for extended periods, or using certain features in hot conditions could cause the device to overheat. When the interior temperature exceeds the normal operating range, these changes occur to protect the device’s internal components.

How to Avoid and Address Overheating Issues

Our iPhones are powerful devices, but they’re also sensitive to temperature changes. Overheating can lead to serious issues, including charging problems. But don’t worry – in this section, we’ll explore some simple strategies to avoid and tackle overheating issues, ensuring your iPhone stays cool and charges efficiently.

Let’s dive in and learn how to keep your device at the optimal temperature.

  1. Avoid Extreme Temperatures: Try to use and charge your iPhone in environments where the temperature is within the recommended range. Avoid leaving your iPhone in your car, as temperatures can exceed this range quickly, especially on hot days.
  2. Keep Out of Direct Sunlight: Direct sunlight can cause your iPhone and the charging pad to overheat. When using or charging your iPhone, do so in a shaded area.
  3. Limit Intensive Usage While Charging: Using graphics-intensive or processor-intensive apps while charging can lead to overheating. If possible, limit such usage while your device is charging.
  4. Ensure Proper Ventilation: When charging your iPhone, especially on a charging pad, ensure adequate ventilation. This helps dissipate the heat generated during the charging process.
  5. Software Update: Always keep your iPhone’s software updated. Some updates contain improvements to the system’s ability to manage heat effectively.

If your iPhone overheats and displays a temperature warning, turn it off and move to a cooler environment. Allow it to cool down before attempting to use or charge it again.

Final thoughts

Understanding the role of temperature in your iPhone’s performance is crucial in maintaining its longevity and avoiding charging issues. By observing good practices, such as keeping the device at optimal temperatures and avoiding intense usage while charging, you can prevent overheating and ensure your iPhone stays powered up when needed.


Why does my iPhone stop charging when it gets too hot?

When an iPhone becomes too hot, it activates built-in protections to prevent damage to its internal components. This includes slowing or stopping the charging process until the device cools to a normal temperature.

What causes my iPhone to overheat while charging?

Several factors can cause your iPhone to overheat while charging. These include extreme ambient temperatures, exposure to direct sunlight, using processor-intensive apps while charging, and lack of proper ventilation.
