What is happening and why it is annoying
You put your iPhone on charge overnight, and in the morning it is at 3%. Or the lightning icon flashes, but the charge doesn't increase. Or nothing happens at all. This can happen with any model — from a 6 to a 15. There are usually three reasons: the cable, the adapter, or the port on the phone itself. Less often, it is a software glitch or something inside the board. Let's figure it out step by step, from simple to complex.
The cable — culprit number one
Honestly, in most cases that are brought to us, the problem turns out to be the cable. They die quickly. Especially if the phone lies on a bedside table and the cable is constantly bent near the connector — the insulation cracks, and the wires inside break. It might look fine on the outside, but it won't work anymore.
It is easy to check: take another cable. Preferably an original Apple one or an MFi-certified one. Often, an iPhone won't even see cheap cables without this certification — it will simply refuse to charge and show a warning about an incompatible accessory.
The adapter — check this next
If nothing has changed with a different cable, look at the adapter. Plug it into a different outlet. It sounds trivial, but we had a case: a man brought in an iPhone 12, fully convinced that the problem was the port. It turned out that the extension cord on his desk was overloaded, and there simply wasn't enough power. He plugged it into the wall, and everything worked.
Try charging the phone from another adapter or from a computer via USB. If it charges from the computer but not from the adapter, the adapter is dead. If it doesn't charge from anything, we look for the problem further.
The port — look at this last
The Lightning or USB-C connector on an iPhone is small, and all sorts of things get packed in there. Pocket dust, lint from a bag, crumbs — all this gets compressed and literally prevents the cable from fully entering the connector. The contact is lost.
Take a flashlight and look inside the connector. If you see gray lint or fibers, carefully clean it with a wooden toothpick. Do not use metal, or you will scratch the contacts. A can of compressed air also helps.
We often get iPhone 13s brought in with complaints that charging only works if you hold the cable at an angle. You look under a magnifying glass, and the port is so clogged that the cable physically cannot go all the way in. We cleaned it right in front of the client, and it charged without any issues.
What you can do yourself — step by step
- Try another cable — original or MFi-certified.
- Change the adapter and plug it into a different outlet.
- Charge from a computer via USB to rule out the adapter.
- Inspect the port with a flashlight, clean it with a toothpick if necessary.
- Restart your iPhone — sometimes it helps with software charging freezes.
If after all this the phone still doesn't charge, the issue is definitely not the cable or dirt.
When you definitely need a technician
There are situations where you can't do anything yourself. If the phone has been in water — even if it dried out and is working — the port could have oxidized. Oxidation kills contacts slowly, sometimes a week after getting wet. If the iPhone was dropped and stopped charging after that, most likely something shifted inside or a contact on the board came loose. A toothpick won't fix that.
It also happens that you've checked everything, replaced everything, and there is still no charge. Then the problem might be in the power management chip on the board — this is a repair at the microchip level, and you can't do it without special equipment.
