iOS 16: What is “iPhone charging in standby mode” and what to do if you see it

iOS 16 brings many new features to iPhone, such as the depth effect on the lock screen, personalized surround sound and live subtitles. However, one feature that took a while to figure out is how iOS 16 keeps the iPhone charging in standby mode when it reaches a certain temperature level. And if you’ve also encountered this error message, here’s exactly what’s going on and how you can deal with it.

Once you get this warning, your iPhone will stop accepting power. Even though it says that it will recover when the iPhone returns to normal temperature, there are ways you can prevent it from happening completely. Before we get into that, let’s understand the need and importance of this feature.

Standby charging due to iPhone temperature: A much needed feature

When Apple introduced the battery level indicator on the iPhone, it made us pay close attention to the rate at which it drained from a full 100%. Many users, including us, have started looking for and using features that ensure battery safety and health. And if there’s one thing we learned, it’s that high battery temperatures were a major cause of battery drain.

Apple used to issue a full-screen warning when your iPhone’s temperature exceeded acceptable levels, even while charging. However, with iOS 16, Apple has taken an extra step to keep the iPhone charged without manual intervention when the temperature level soars.

This is a much needed feature as it keeps the battery safe and prevents it from heating up further. It also prevents potential overheating from affecting other internal iPhone components.

But why is overheating bad for batteries? Let’s find out.

Lithium-ion batteries and overheating

Lithium-ion batteries are sensitive to heat. When they are exposed to high temperatures, the chemical reactions inside them are affected. The electrolyte in the battery facilitates the movement of ions through the anode and cathode.

However, the electrolyte is very sensitive to changes in heat, and when the temperature becomes high, it can crystallize and clog the anode and cathodes.

This prevents them from storing lithium ions. Simply put, excess heat prevents the battery from functioning properly. This can increase battery life and, if repeated, degrade battery performance over time.

So you have to be careful with it. In the next section of the article, we will learn how you can prevent your iPhone from overheating while charging and fix the “iPhone Charging Paused” message.

iPhone charging error message on hold: what to do

Here are some ways you can make sure your iPhone stays at ambient temperature and prevent iOS 16 from displaying the “iPhone Charging Suspended” warning.

1. Remove the iPhone case

If you’re using a thick back cover for your iPhone, chances are it can help trap heat. So, if you feel your device heating up, remove the case while charging. This will provide better ventilation for your iPhone and won’t trap heat.

2. Move to a less hot environment

Apple recommends using iPhone below 45°C (113°F). So, if you’re charging your device under the hot sun with a power bank, try going indoors and charging your iPhone. This can prevent the iPhone charging pause notification from appearing on iOS 16.

3. Avoid charging in the car

While it’s convenient to place your device on top of your car’s wireless charging pad, you need to be careful of the hot sun, which can easily heat up your car and, by extension, your iPhone. It can also heat up the battery. So, only charge your device in the car when absolutely necessary.

4. Turn off your iPhone

If you notice your iPhone heating up while charging, unplug it and let it cool down a bit. Turn it on again and check if the temperature is normal. If it heats up again quickly, you may need to verify the authenticity of the accessories or contact Apple Support.

5. Use only MFI certified accessories

Do you see an inexpensive iPhone power adapter and lightning cable? If you are tempted to buy one of these, we advise you to avoid them. It is necessary to check the presence of the MFI – Made for iPhone/iPad certification and only then make a purchase.

Here is a list of authorized MFI manufacturers on Apple’s list. (make sure you agree to the terms to view the listing). These manufacturers produce accessories that have passed all quality checks for your iPhone and will not harm or affect your device when you use the accessory.

6. Choose a slower charge

Fast charging accelerates chemical reactions and thus produces more heat. So, if your device heats up while charging, make sure to use a lower wattage power adapter for a while until it cools down. This will help you fix iPhone charging stopped message.

7. Turn off and wait for the iPhone to cool down

Finally, you can try turning off the device and waiting for the iPhone to cool down. You can restart as soon as the temperature returns to normal. Here’s how you can turn off your iPhone.

Step 1: First, you need to turn off the device.

  • On iPhone X and above: Press and hold the Volume Down button and the Side button.
  • On iPhone SE 2nd or 3rd generation, 7th and 8th series: Press and hold the side button.
  • On iPhone SE 1st generation, 5s, 5c, or 5: Hold the power button at the top.
Restart your iPhone

step 2: Drag the power slider to turn off the device.

step 3: When the iPhone cools down, turn on the device by pressing and holding the power button on the iPhone.
