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!

Found and fixed the problem on my own then wondered: how often does this occur? Googled and sure-nuff! Could have saved some time if I Googled first. What a dirty little problem with that lint-compacting plunger of a lighting plug.


Clean the plug, dig the dirt out of the socket then clean with electronic cleaner. I'm a retired electronics tech and I went through cans of the stuff that fixed many radios. Never worried about shorting, or damage - its designed for electronics.


Clean the flat plug contacts with a clean eraser. The socket is harder to access and the raised contacts likely much more fragile than the plug. Just spray with electronic cleaner then insert the cleaned plug and move it around while wet with the cleaner.


Now I may blow the socket out before inserting, but moist breath may corrode...perhaps my bicycle pump? Syringe?

Same problem described in the first post, intermittent connections, and this morning I woke up to find my phone not charged. I used a toothpick and pulled a large amount of lint out of the lightning port. Connection works solid again.


Somebody should start selling a lightning port cap that stops lint getting in. Looking at what they charge for accessories they could probably sell it for like $15, sadly!

I advise against any metal probe because of possible damage, but the toothpick worked well. Depending on the type of toothpick, it may help to snip off the very tip on one end to provide a more blunt "scraper." Amazing how much lint and other crap was in there. I'd tried canned air but that stuff really gets packed in there And air alone didn't do much. Probably a good reason to not carry the iPhone in your pocket or to get a case with a port cover. Kind of reminds me of the early Mac days when you could fix many ailments with a paperclip.

I had exactly the same issue as bought an used iphone 5S from someone. I was about having it fixed for 50 bucks but the repair guy kept changed the appointment due to he is so busy. But after reading your message, I decided to do the same but i cleaned with a super small needle and took out a lot of fiber or black cotton. It worked nice after cleaning. I don't have to wiggle or hold the cable anymore. Thanks a lot

The problem is definitely due to a build up of dust and fluff in the charging port. I just cleaned it out with a very small brush. Actually quite astonished at how much had built up in there. I could see it all falling out. After a few minutes of brushing the cable connected perfectly. Easy! And to think I was going to take it into O2 for repair, which would have meant I would likely have been without my I phone for at least a week, if not longer!
