Why Is Your iPhone 12 Not Charging?

Apple stopped providing chargers in the box of the iPhone 12 and later devices. So, most people use their older 5W adapter or third-party Android chargers to charge. I was doing the same when I ordered the iPhone 12 Pro.

The power output of Android chargers is not appropriate for the iPhone 12 power rating. That’s why many iPhone 12 users are facing charging problems.

If you’re using an Android fast charger or any third-party adapter to charge your iPhone, stop using it. This could be a reason why your iPhone is not charging.

Apple always recommends using Apple’s original 20W adapter to charge your iPhones. If you already ordered from an online e-commerce website, ensure it’s original.

Many fake Apple 20W adapters are listed on eBay and other online platforms. You can try a different charger to check whether your iPhone is charging. If it’s charging with another Apple adapter, it means your one is fake or faulty.

Always buy an Apple 20W adapter from a trusted seller or Amazon or directly order from Apple’s official website or local Apple store.

If you have never cleaned your iPhone charging port, then you may damage your charging port. I have published a detailed guide on charging port cleaning and safety majors. Please read it before proceeding to clean your charging port.

Sometimes MagSafe case also creates interference in wireless charging. If your phone has any protective case installed, take off the case and place your iPhone on the wireless charger.

The wireless charging problem often occurs due to a thick plastic or armored case installed on the smartphone. My friend’s iPhone 12 Pro was also not charging wirelessly because of the armored case.

4. Place At The Center

A copper coil on the back of your iPhone generates electromagnetic flux that receives power from the wireless charging pad.

If your phone is not placed at the center of the charging pad, it may disturb the magnetic flux, and your iPhone won’t charge wirelessly.

So, always place your iPhone in the center of the wireless charger to receive the induction energy; hence the battery recharges properly.

5. Update iOS

If your iOS is outdated, you might face a wireless charging problem. So, first, update the iOS software from iPhone Settings and restart your phone to apply the updates.

How To Fix iPhone 12 Won’t Charge Past 80?

Everyone prefers to recharge their smartphone battery to 100%, which will put extra stress on lithium-ion batteries, ultimately reducing the battery lifespan.

Apple recommends keeping your iPhone battery recharged between 20% to 80% for maximum lifespan.

1. Disable Optimised Battery Charging

If you overcharge your lithium-ion battery, it will lose its power-holding capacity because of overheating.

To extend the battery lifespan, Apple introduced Optimised Battery Charging feature on iPhones and MacBooks.

This feature reads your charging patterns and pushes the charging once the battery percentage reaches 80%. That’s why your iPhone 12 is charging on hold at 80.

You can easily bypass this by disabling Optimised Battery charging from your iPhone settings. Go to Settings > scroll and tap on Battery > tap on Battery Health > disable Optimised Battery Charging.

2. Cool Down Your iPhone

Higher temperature is bad for lithium-ion batteries, and Apple protects battery health by determining the iPhone’s temperature.

If you are playing games for a prolonged, your iPhone might be overheating. The Apple Bionic chip will stop the charging activity for an extended battery lifespan, and your iPhone will not charge fully.

Leave your iPhone for a few minutes to cool down. Once it reaches the normal temperature, insert the charger, and it will start charging again.

How To Fix iPhone 12 Charging Slowly?

If you use a 5W adapter, your iPhone 12 will charge slowly. To increase the charging speed, try Apple’s 20W power adapter. Click the buy[MFi Certified] iPhone Charger

How To Fix iPhone 12 Not Charging After Water/Moisture Detected in Charging Port?

iPhone Liquid Warning

Have you accidentally dropped your iPhone 12 in your bucket or swimming pool? Don’t worry; the iPhone 12 is IP68 rated, which means it can withstand up to 6-meter depth for 30 minutes.

But you may get a warning when you connect the lightning cable. If you get a moisture/liquid detection alert in the lightning port, try the following methods to charge your iPhone-

1. Dry Out Charging Port

The step is to dry out the lighting connector so that the iPhone liquid detection alert goes away and it starts charging. For drying out, hold your iPhone in the standing position so that the charging port faces down.

Now, give a few gentle taps on the top of your iPhone so that any moisture or liquid comes out from the lighting port. Do not use an air blower, as the liquid may go inside and damage the motherboard.

Now wipe out all the moisture of the lightning port with the help of a Q-tip. After wiping all the visible moisture, play a heavy game so that your iPhone heats up and vaporizes the moisture.

Once it’s dried completely, connect the lighting cable, and your iPhone will start charging.

2. Use Wireless Charger

If you insert the charger into the iPhone charging port and it still says, “Charging is not available because liquid has been detected in the lightning connector,” you can skip the wired charging until moisture completely vaporizes.

Use a wireless charger to charge your iPhone. After a few hours, liquid vaporizes from the port, and you’ll be able to charge it again.

3. Emergency Override

If you have to take some important call and your iPhone gives a moisture detection alert, you can override it. Insert a lightning cable in the charging port and tap on Emergency Override when a liquid detection alert pops up.

How To Fix iPhone Stops Charging After a Few Seconds?

If your iPhone starts to charge and then stops after a few seconds, it means there are issues with the output current.

When you insert the lightning cable, a small amount of power goes to your iPhone, and the processor shows the charging icon.

But, this power input is not sufficient to charge your iPhone battery. So, first, inspect the charging cable and see if it’s frayed, torn, or broken. If the cable is faulty, replace it immediately.

If you’re charging your iPhone from a computer USB hub, it may also create this problem because the current output is low on the laptop and computer’s USB hub.

So, try a new adapter that supplies rated output power to your iPhone and battery recharges. You can try your family members’ charger to verify that your charger and cable isn’t faulty.

Also, inspect the charging port on the bottom and remove any debris from the charging port. If that doesn’t help, take your iPhone to the nearest Apple care to fix the issue.
