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!
Thank you, TnD1W! About 15 months after buying an iPhone 5, my Apple cable started to be intermittent. I bought two new cables on eBay from two different sellers, but neither new one worked at all. After seeing your post, I dug around inside the connector with a toothpick and pulled out a bunch of lint, then blew it out with compressed air. Suddenly all three cables started working flawlessly! Since there is no Apple store on the island I live on, I wasn't sure what I was going to do. Thanks again!
Thank you so much TnD1w
I also had this problem with all of my lightning cables, but did not realized it was simply dust in my iPhone port. I used a paper twist tie to remove gently the dust, and voilà, the port works fine now.
