How to Fix iPhone Won't Charge or Charging Slowly Problem?

After you are sure that your iPhone is really not charging or has a charging problem, you can fix it by taking a good look at the four components that are involved: USB cable, charger, charging port and iPhone itself. If the hardware goes well, the charging problems might be attributed to your iPhone system issues.

1. Check if USB cable is working or not

This is pretty obvious. Whether your are using lightning cables or 30-pin dock connector cable, check the cable and see if it is frayed or worn. If the cable looks fine, use other cable and and see if your iPhone is charging. If it is, then you need to change a new cable.

In fact, USB cable is covered under the iPhone' s warranty. Therefore, for those users whose iPhones are still under warranty, you can go to local Apple Store with the old cable and get a free new lightning cable.

However, in most cases, the lightning cable that comes with your iPhone is very durable and  gets damaged after the warranty is expired. Some users may replace the lightning cable with 3rd-party cable that costs less than lightning cable. It is okay to use non-Apple cable but always pick Apple certified cables, which are marked with "Made for" label like this:

Some cheap and low-quality cables that are not authorized by Apple might be unable to use to charge your iPhone. The error "This cable is not certified and may not work reliably"may appear and prevent the cable from charging iPhone.

2. Try Another Charger

Charger can also be the reason why your iPhone won't charge. There are many power sources that you can connect your iPhone to: wall charger, computer USB port, car charger, portable charger. Try to charge your iPhone with other sources. For example, if you were using a wall charger, connect your iPhone to a laptop USB port. If it works, then you would know that the charger is broken.

3. iPhone Charging Port Not Working

But what if your phone won't charge and it's not the charger? For this case, you should check the iPhone charging port. Sometimes, iPhone charging port can be clogged with dust, debris, lint, or some other small object, which also prevent iPhone from charging. Now, let's see how to clean iPhone charging port below:

4. Take your charging iPhone to a cooler place

You should notice that the software of your phone would limit charging above 80 percent when your iPhone gets too warm. The battery itself will give out the heat. In addition, the high air temperature can even make thing worse. So you can move your iPhone to another location that is cooler to give it a shot and then check if the problem is solved or not.          

5. System Issues Troubleshooting

Charging involves not only the accessories but also iPhone itself. It is the software that recognizes the power source and starts the charging process. So if there is something going wrong with the software, your iPhone won't charge properly. To solve the problem, you can try to reboot or restore iPhone.

Firstly, you can follow the below instruction to restart your iPhone.

For iPhone X/8 Plus/8, you need to press and quickly release the Volume Up button. Then press and quickly release the Volume Down button. After that, just keep pressing the Side button until you see the Apple logo.

For iPhone 6s and earlier, you need to press and hold both the Home and Top (or Side) buttons until you see the Apple logo.
