10 Ways To Fix iPhone 12 mini Not Fast Charging Issue

Is your iPhone 12 mini charging slowly? Don’t panic! In this article, we’ll guide you step-by-step how to fix the iPhone 12 mini not fast charging problem!

A lot of people tend to complain of slow charging issues on their iPhone 12 mini. If you too are tired of keeping your phone plugged in all day, don’t worry, we’ve got your back. Here’s a simple guide on how you can fix the slow charging problem on your iPhone 12 mini.

Fast charging is the perfect feature for people who hate to wait for their phones to get powered up before leaving for an evening out with friends and family. After just a short charge time, you can use your phone for hours. Apple includes fast charging in the latest iPhone models including iPhone 12 mini.

Although it is a big selling point for Apple, it can also be problematic at times. Here are a few fixes you can try if fast charging isn’t working on your iPhone 12 mini.

Why does my iPhone 12 mini charge slowly?

If your iPhone 12 mini seems like it is charging slowly, there’s most likely a simple reason. The old 5-watt iPhone chargers will work with the iPhone 12 mini, but can only charge at a lower power throughput. However, a newer 20-watt charger and USB-C Lightning cable can charge your iPhone 12 mini at full speed. So if you have upgraded from an older iPhone, the chances are your power brick is outdated. In this article, I’ll explain why your iPhone 12 mini is charging slowly and show you how to fix the problem for good!

Fix iPhone 12 mini fast charging not working

If your iPhone 12 mini is charging slower than it should, here are some ways to fix it.

Note: the solutions discussed in this article applied to iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max

Without further ado, here are all the ways you can fast charge iPhone 12 mini.

1. Make sure your Charger Supports Fast Charging

For fast charging to work, your phone charger must support it. To fast charge an iPhone 12 mini, iPhone 12 Pro, or iPhone 12 Pro Max, you need to use a higher-wattage power adaptor. The iPhone 12 mini doesn’t come with charging adapter, so you may have to buy one separately. Apple recommends its 20 W USB-C charger, however any higher-rated USB-C adaptor will suffice. You can even get duo port chargers from third-party manufacturers that can fast charge two iPhones at a time.

If you have a newer-generation MacBook Air or MacBook Pro, you can also use that USB-C brick to fast charge your iPhone 12 mini as well. The iPhone 12 mini will only charge at about 20 watts of maximum throughput, but you can safely use higher-wattage USB-C chargers too. You just won’t see any additional speed.

A charger that doesn’t have a label that says Fast Charging, Adaptive Fast Charging, or something similar signifies that it isn’t compatible with fast charging. This will charge your iPhone 12 mini a lot more slowly.

2. Check your Cable

Of course, fast chargers also require a Lightning to USB-C cable. The older USB-A square Lightning cables do not support fast charging speeds. With a 20-watt brick and Lightning to USB-C cable, you can go from zero to 50% charged in half an hour, and fully charge an iPhone 12 mini in about two hours.

If your iPhone 12 mini charging speeds have dropped significantly in the last few days, the reason could be a damaged USB cable. Generally, these cables tend to lose their efficiency over time and may break down at any moment without even showing any signs of damage.

So, try replacing your cable and see if it was the real culprit. Also, while buying a new cable, always prefer the ones from good brands that have a higher gauge and are compatible with your charging adapter’s output ratings.

3. Clean the Charger Port

Another possible reason fast charging does not work on iPhone 12 mini is the accumulation of dirt or residue in the charging port. Your charger can’t operate at its full capacity or even at all if it has dirt or lint in it.

Using a toothpick or needle, remove any dirt, grime, or other residues. You can also use a cotton swab and rubbing alcohol inside the charging port in circular motions. Afterward, put it in a cool, dry place for at least an hour. Don’t worry about the liquid in the dock; it will naturally evaporate.

4. Avoid Using your iPhone While Charging

Using the phone while charging wastes a significant amount of juice on running up the display and other resources. This parallel power consumption reduces the current you’re battery is being charged at, thereby degrading the overall charging speed.

Similarly, the iPhone tend to heat up if you use them while charging. When the heat goes above a specific limit, the phone starts throttling the charging speed as well as performance in order to maintain the temperature.

Besides that, the excess heat from the display and processor can cause the iPhone battery to drain fast or suffer from severely reduced cycle life. Hence, it’s better to avoid using your iPhone during charging.

5. Avoid Charging from Laptop or PC

Ever wondered why your iPhone 12 mini charges so slow when plugged into a PC or Laptop? Well, it’s because those ports are primarily meant for data transfers and are not capable of supplying the amperage required for fast charging.

For instance, a computer’s USB 2.0 port can shell out a maximum of 0.5A while the USB 3.0 port can provide a peak charging rate of 0.9A, which is way lower than current charging standards. A dedicated wall charger, in comparison, is usually rated at 2A.

6. Change the Charging Outlet

There is also the possibility that a faulty outlet does not supply enough current to support fast charging. Your charger won’t be drawing the power at the required rate to fast-charge your iPhone 12 mini in the absence of sufficient power.

Try a different charging outlet to see if that makes a difference.

If you are using any other power source, like an external power bank, make sure it has enough wattage to support fast charging on your iPhone 12 mini.

7. Update Your iPhone

A recent software update may have altered your iPhone 12 mini charging speeds or battery performance. If so, then wait for a fix from Apple. Else, you can try downgrading the software to the previous version either manually or by taking your phone to your nearest Apple Store.

To check for an iOS update:

1. Open the Settings app on your iPhone.
2. Go to General > Software Update. Install the latest update.

8. Turn Off Cellular Data or Wi-Fi

Even when you aren’t using your iPhone, cellular data and Wi-Fi connections might still be drawing the power. Turning them off may speed up the charge time of your iPhone 12 mini.

To make things easier, always put your phone in Airplane mode before connecting your charger to speed up the process.

9. Fast charge iPhone 12 mini using wireless charging

Wired charging always beats outs wireless for speed and efficiency. However, using the Apple MagSafe charger, you can get reasonably fast inductive charging performance.

The MagSafe puck magnetically snaps to the back of the iPhone 12 mini, and that secure fit enables a faster charging speed than standard Qi. Using MagSafe, you can achieve up to 15-watt charging speeds. Using MagSafe, you can charge from zero to 50% in about 50 minutes, and attain 100% charge in about 2.5-3 hours.

In contrast, using a basic Qi charger, the iPhone will charge at a maximum of 7.5 watts. This is equivalent to about four-to-five hours charge time to reach 100%, depending on model. Although this is much slower than the above alternative methods, if you are just charging your iPhone at bedtime on a nightstand or similar, it’s probably fine and is otherwise the most convenient option.

10. Do a Factory Reset as the Last Option

In case none of the fixes work, you can try factory resetting the iPhone. As the name suggests, a factory reset returns your iPhone its to default settings.

This gives your phone a fresh start and may solve the problem of fast charging not working on iPhone 12 mini. Since the process deletes all of your data, backup your iPhone before you perform the reset.

To reset your iPhone:

1. Open settings.
2. Tap general.
3. Tap transfer or reset iPhone.
4. Tap erase all content and settings.

Start Fast Charging Your iPhone 12 mini Again
