Why Does My iPhone 12 Mini Not Charge While It is On?

Many iPhone users have encountered the frustrating issue where their iPhone 12 Mini does not charge when the device is turned on. This problem can arise due to several reasons, including the use of an improperly powered charger, a dying battery, or software issues. Let's explore each of these potential causes in detail and provide solutions to help you resolve the problem.

Incorrect Charger Power Rating

One of the most common reasons why your iPhone 12 Mini does not charge while it is on is because you are using an AC adapter with a too low power rating. These adapters have enough power to charge your phone when it is switched off but may not supply sufficient power to charge your active device.

Additionally, you might be using an old AC adapter meant for an earlier model that drew less power. For the iPhone 12 Mini, which is a modern model, you need a charger that can deliver more power. A standard 5W charger, which was common for older iPhones, is often insufficient for newer models. You should consider upgrading to a charger with a power rating of 20-30W.

Battery Near End of Life

Your iPhone 12 Mini might also not charge while on due to a dying battery. As the battery ages, it can no longer hold a charge effectively and may not have the capacity to support both charging and sustaining the device's operation. When the battery reaches its end of life, a charger will struggle to provide the necessary power to keep your phone on while simultaneously charging it.

Due to the advanced battery capacity required to power a modern device like the iPhone 12 Mini, it's recommended to replace the battery if you suspect it is malfunctioning.

Software and App Issues

Sometimes, the issue might be related to software or apps on your iPhone. If your phone is using power faster than the charger can supply, it can cause charging issues. In such cases, you can try a few troubleshooting steps:

Try a different cable to charge with, as sometimes a faulty cable can cause charging problems. Boot your phone into safemode and see if it charges. If it charges in safe mode, then it could be an app causing the issue. If it doesn't charge in safe mode, perform a factory reset to eliminate the possibility of problematic apps or software causing the issue.

However, if these steps do not resolve the issue, it might indicate a hardware problem. In this case, it's best to take your iPhone to an authorized service center for further diagnosis and repair.

Professional Cleaning and Reliable Chargers

Another potential cause is a dirty charging port, which can lead to poor contact and charging issues. Have your charging port professionally cleaned to ensure reliable connectivity.

To avoid further issues in the future, invest in a reputable charger, preferably an Anker brand or an original Apple charger, to ensure that you have the necessary power to charge your iPhone 12 Mini properly. According to Apple, a 20-30W charger with a USB-C cable is recommended for the iPhone 12 Mini and other modern iPhones.

Remember, using a charger that is not certified or is of substandard quality can not only lead to charging issues but can also be potentially harmful to your device and even pose safety risks.

By taking appropriate steps to address the reasons for your iPhone 12 Mini not charging while on, you can help ensure that your device is working optimally and can continue to provide you with reliable service.
