The iPhone features a unique function that temporarily halts charging if the device's temperature is not suitable for safe charging. You'll notice a notification on your screen saying “Charging on Hold – Charging will resume when iPhone returns to normal temperature.” This alert typically appears when the iPhone is too hot, such as when left charging in a warm car on a sunny day, or just before or after the temperature warning shows up. However, you might also see this message when the iPhone is too cold, for example, in sub-zero conditions at a ski resort or if it has been stored in a freezer for a long time.

As indicated by the notification, the iPhone will not charge while this alert is displayed. Here are some tips to resolve this issue and get your iPhone charging again.

Resolving the iPhone “Charging on Hold” Temperature Notification

If you encounter the temperature warning that charging is paused until the iPhone reaches a normal operating temperature, you can usually resolve the issue quickly by following a few steps.

Before you start troubleshooting, remember that the iPhone employs passive cooling technology, meaning heat from intense processor usage dissipates through the device's frame and enclosure. This knowledge can help you avoid situations where your iPhone might overheat due to being covered or exposed to extreme temperatures.

1: Move iPhone Away from Extreme Temperatures & Sunlight

The first step is to remove the iPhone from any extreme temperature conditions. This involves relocating it from overly warm or cold environments to a more moderate temperature setting.

Also, ensure the iPhone is not in direct sunlight, as the dark screen and the glass and metal casing can become very hot under the sun's rays.

Apple suggests keeping the iPhone in environments with ambient temperatures between 60° F and 72° F, which are quite moderate and perhaps typical for the Apple Cupertino campus. However, temperatures in other parts of the world can be much hotter or colder, so be aware of extreme temperature situations.

After moving the iPhone to a more temperate environment, allow it to cool down (or warm up if it was too cold), and then attempt to charge it again.

2: Close Apps That Are Heavily Using the CPU

To help the iPhone cool down and resume charging, close any apps that are heavily taxing the CPU. Many apps, especially social media platforms like TikTok, Instagram, FaceBook, Twitter/X, Snapchat, and YouTube, consume a lot of CPU power, even when not actively used. Apps that stream a lot of video content or frequently use GPS and location services, even when idle, are particularly demanding. Some games can also be resource-intensive, though most do not run aggressively in the background.

Swipe up from the bottom of the iPhone screen to access the app switcher, and swipe up on the apps you wish to close, focusing on those that are heavy users of CPU resources.

Closing these apps will reduce the load on the device's processor, helping it to cool down.

3: Lock the Screen & Take a Break from Using the iPhone

After moving the iPhone away from extreme temperatures and direct sunlight, and closing high-CPU apps, lock the screen and refrain from using the iPhone for a while. This will help regulate the temperature, allowing charging to resume shortly.

Be patient; once the iPhone detects safe temperature conditions, it will start charging again.

4: Remove Any Items Covering the iPhone, Including the Case

If your iPhone frequently overheats, it might be due to being covered by clothing or a case in temperatures where it would normally function fine.

If the iPhone is in a case and overheating, try removing the case. If it's wrapped in thick clothing or blankets, place it somewhere with better air circulation.

iPhone Constantly Pausing Charging? The Battery Might Need Service or Be Failing

It's possible that the “Charging On Hold” message appears because the battery requires servicing or is failing.

Check your iPhone battery's condition by navigating to Settings > Battery > Battery Health.

If you see a message like “Your battery’s health is significantly degraded,” it's time to replace the battery.

Sometimes, a failing battery can overheat more easily, causing charging to pause or the iPhone to malfunction. Replacing the iPhone battery can resolve this issue.
