Iphone 5 lightning port charging problem - SOLUTION!

Just wanted to share a solution to my charging problem. Very quickly my phone developed a problem where I couldn't get it to charge. The connector didn't feel sloppy, but if I twisted it to the side, I could get it to make a connection. However, if I let go or bumped the phone it would immediatly disconnect. Sometimes it would take a easy dozen tries to get the phone to establish a connection. Often I'd come back only to find that it had lost the connection and stopped charging. Took it to the Verizon store and it worked fine on their cords. Could be the cord, but I have multiple cords stashed in different locations and they all went bad at the same time. That suggests to me that it's the phone and not the cord. I tried to fish for some lint in the port and that definetly seems to be part of the problem. I used a bent paperclip with no ill effects, but I'd be more comfortable with a flat toothpick. Just stay away from the sides of the port as I don't know how fragile the connection wires are. In my case, I was going for the bottom of the port. Reach into the port and try to scrape out any packed in lint from the back of the port. I'm thinking the lint may prevent the plug from fully seating thus creating a poor connection. This helped a fair amount, but the connection still needed improvement. Last night I bought a can of electrical contact cleaner and thought I'd give it a try. I'd admit that I was a bit nervous to spray this into my phone, but I needed to try something. Using the included tube, I sprayed a tiny amount of cleaner into the port. The cleaner will get outside the port, but I don't see any signs of damage to the Belkin case, phone body, screen or disposable screen protector. While the port was still wet, I grabbed a cord and plugged it in several times hoping to agitate the solution and mechanically clean the connection. A mini q-tip would work even better. Instantly I found a signficantly improved connection. Plug it in and boom, good connection. First try every time. No wiggling necessary. I did this last night at home and I just plugged the phone in at work; again got a good connection. Now, I only tried this last night, but it certainly looks like the problem is dirt, grime and maybe a touch of corrosion that's causing the problem. Clean the port out to remove any debris and then apply a quick shot of contact cleaner and you should be good to go!

Scratch that, further amount of cleaning WAS needed. You really have to look in there with a torch and bend a tooth-pick into a bit of a hook - to scrape between the connector pins. Don't stop until it's spotless. Phew! I was going to get desperate and try bending the port next which would have busted it.

My experience: no lint, but on close inspection of the connector, I noticed pin 4 on both sides of the connector had a black build-up. This was apparently carbon, as after I'd cleaned it, the connector metal was pitted (indicating there had been some arcing between it and the phone contacts (😮!!!). This also indicates that there should be similar charring & pitting on the phone-side contact.


It took quite a bit of rubbing with a toothpick and 70% rubbing alcohol to clean the pin on the cable again. (I don't know if 90% alcohol would make it easier to clean or not, but next time I would try it.)


As far as cleaning the phone-side contact for connector pin #4, that's pretty dicey:

The contacts are raised, "springy" wires.

Issues to deal with, given the structure, small dimensions and lack of visibility on the phone-side:

  • You can rub only "in and out" -- not side to side -- on the contacts.
  • It's nearly impossible to access only 1 pin in the hole at a time.
  • You don't know what the conditions are on the pins.
  • You don't know when your cleaning effort is complete.

I turned the phone off, and used an alcohol-saturated toothpick in the connector hole. Afterwards, I let it dry for many minutes.

This technique seems to have worked.

The good news is that the contacts seem to be on the "back" side of the connector hole only.


Caveat emptor!

My phones charging cable started to not connect well. The cable sat loose in the charging port, and it was a struggle to make the phone charge. After doing some reading, I came to the conclusion cleaning it couldn't hurt. Power down the phone and get yourself a sturdy toothpick and a GUM cleaner for flossing in between your teeth. I have found the best application to start with the toothpick. This will help clean any gunk and loosen up the debris inside. Shine a flashlight inside and you will be able to see all the debris. Use the the toothpick a few times and blow it out with your breath. Finish up the cleaning with the GUM cleaner, you will be surprised the amount of dust/lint that will be removed. The small GUM brush also helps clean the contacts inside. Once done my phone connector made a solid connection once again and was no longer loose even the tiniest bit!


This is also a fantastic way to clean your head phone jack connector and speaker/mic ports!

Many thanks for posting this - worked a charm! I've had the same problem for a few weeks and despite having used a fine brush to clean out the charger socket - and despite not being able to see any dirt in there - I got a toothpick and started to gently scrape away. Genuinely amazed at how much lint I've managed to extract!!!! Just plugged in and got perfect contact again. Looked at other fixes which tended to suggest replacement part but so glad I found this solution. 🙂🙂

I must say I was a bit skeptical about this solution. My Iphone 5S was showing the same charging problems described here for several months. Very annoying, I had to leave it quite still for a complete charge, sometimes moving the plug left or right to start a charge. I did not believe it was a dirt problem, but what the hack, let´s give it a try... I got a small plastic toothpick, sharpened it a little to make it flat and thin and... an enormous amount of lint and dirt came out of the port! Cleaned after several minutes of delicate work, a bit of contact cleaner spray, all is well and working. The lightning port is redeemed to me!
