I see a charging symbol, but the battery percentage is not increasing.

My iPhone 5 was working properly for more than 1.5 years. Now, I'm having a few problems with it. I will explain the problems one by one, after doing all the diagnosis I can on my end:

"The problem is definitely in the gas gauge line between the logic board and the battery.

This could be a failed battery—and if there were no prior repairs, this is most likely.

The most common cause if the phone has been opened, is a missing FL 11 on the logic board. The FL 11 is a tiny component that commonly gets knocked off when people connect or disconnect the battery.

There is also a chance that you could have a secondary defect in the U2 charging IC, which is sporadically charging the battery—but this is secondary to your gas gauge line defect. It's also possible that there's a secondary defect in the charge port itself.

Apple diagnostics won't help you—they will just show how many amps the phone is consuming while charging, which won't help you to narrow down between these possibilities.

Your troubleshooting process should look like this:

1.) Replace the battery.

2.) If the problem isn't solved, look for the FL 11 on the logic board and send the phone out for repair if it's missing.

3.) If this doesn't resolve the problem, replace the dock connector.

4.) If the problem still isn't solved, send the phone out for a U2 IC chip replacement on the logic board."

"It sounds like the problem is the FL11 module on the logic board. It's easy to damage this module while disconnecting the battery from the logic board. I've included a photo for reference.

Confirm that these modules are in place.

If they are missing, you must replace them. This job should be done by a professional, since the logic board is easily damaged.

Here is another thread referring to this issue:

Replace the lighting dock that's the problem

Nitin Sharma, the way to proceed would be a new battery first, if that does not work replace the lightning connector. If even that should fail, you are having problems with the coil on your logic board.

"I am sure that people posting in the thread above have already got their problem fixed one way or another, but just in case, I hope my solution helps anyone in future to try this before trying anything that causes money.

My charging problem started six months back, when my phone would only charge if I jammed the cable a little hard and very slowly keep it in that position. I bought a new cable and it seemed that the problems were solved. However this cable also started behaving like that after some time. Finally, since this morning it did not charge a single percent even if the icon was on. As I watched with horror the percentage going down with my mind not working also, I started looking for answers and bumped to this thread. I noticed few people have said that sometimes they managed to get the thing done by tinkering with the port and/or the battery.

I thought I would take a close look at the port myself without opening the mobile.

Just took a flashlight and a toothpick, and carefully scrubbed away the dirt, lint and shoot that was there. I could hardly believe the amount that was there (obviously living in the the world's most polluted city 'Delhi' does not help.) After eternal ten minutes I plug my jack in and simply connected so snugly. Instantaneously, the charging starts. To me, my procedure did either one of the following things or both

1. If there is continuous shoot buildup inside the female charging port of the phone, it does not allow the cable to fit properly and there may be an interlock in the battery management software of Apple that prevents the charging because of the loose connection.

2. For charging both the respective metal pins of the charging ports of the phone and the cable should make a proper connection. Now when there is dirt between them, it may create a short between the pins that are not supposed to be electrically connected. Again, there may be a software management that acts just like a safety fuse. So scrubbing the minuscule dirt from the pins and then blowing removes any chances of this short.

Hope it helps. If not you can always go for the battery, the ICs and the other things. It's not for no reason that microelectronics fabrication is done in ""clean-rooms"" that cause billions of dollars to build and maintain.

P.S. The first cable is now working perfectly as well."
