iPhone 8 won’t charge properly, says connected but won’t charge to 100%

Hello and welcome to today’s #iPhone8 troubleshooting article. This short guide will tell you what you can do when your iPhone 8 stops charging, or when it charges but in an erratic manner. We hope you’ll find it useful.

Before we proceed let us remind you that you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

 

Problem 1: iPhone 8 won’t charge properly, says connected but doesn’t charge the battery to 100%

I am currently living in Bogota, Colombia and have had my iphone for less than a year. It’s never gotten wet, or been through any major trauma, but for the past several weeks I have had nothing but trouble when charging it.  It always says it is charging (with the lightning bolt), but sometimes it just doesn’t charge. For example, it just stayed on 23% for the past 45 minutes, even though it showed it was charging. Other times it charges quickly, sometimes it charges and then drops a charge. I’m not sure what to do. Again, the issue is not that I can’t get the power adapter connected. It’s that it is connected and SAYS it is connected and yet doesn’t charge. — Stefan K Schwartz

Solution: Hi Stefan. An issue like this may or may not have a hardware aspect as usual, you’ll have to do all relevant software troubleshooting steps. If none of them will fix the issue, then you can assume that it’s due to hardware malfunction. In that case, you’ll have to contact Apple support.

To start troubleshooting the issue, follow our suggestions below.

Use another charging cable and adapter

Sometimes, charging issues are fixed by simply using another set of lightning cable and adapter. Like all electrical and electronic components, these accessories can go bad. Even though the two of them look well, there may be damage inside that you can’t see at all. The lightning cable has fine wires that can get damaged by sudden power surge, or by stretching. The easiest way to check is by using another known working lightning cable and adapter.

Clean the charging port

Your iPhone 8’s charging port is exposed to dust, lint, and debris so there’s always a chance that it may accumulate any of these things. Try to examine the port using a magnifier to see if there’s something that may be blocking the charging cable. If you think there’s something in there that doesn’t belong, use a can of compressed air to dislodge it. Do not stick anything inside to avoid damaging the metal pins.

Recalibrate iOS and battery

The symptoms you mention are consistent with an operating system not getting accurate inputs from the battery. In order to remedy the situation, you want to recalibrate the system. Here’s how:

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Perform a warm restart by holding the Power and Home buttons simultaneously until the startup logo appears.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Reset all settings

If iOS and battery recalibration won’t fix the problem, the next troubleshooting step that you want to do is to reset all settings. While it’s not quite like factory reset, resetting an iPhone’s settings is the less drastic way to return all software settings to their defaults without actually wiping the device. Here’s how it’s done:

  1. Open Settings app.
  2. Tap General.
  3. Tap Reset.
  4. Tap Reset All Settings.
  5. If prompted, enter your passcode.
  6. Confirm the reset.

Factory reset

Should nothing come out positive after resetting all settings, you should not hesitate to wipe the device to return all settings to their factory state.  This procedure will delete your personal data so be sure to back them up first. You can use iTunes or iCloud to back them up.

  1. Open Settings app.
  2. Tap General.
  3. Tap Reset.
  4. Tap Erase All Content and Settings.
  5. If prompted, enter your passcode.
  6. Tap Erase iPhone.

Set your iPhone as new device or Restore

Once you’ve done the reset, the next thing that you want to do is to decide whether or not to set it as a new device, or to restore from an old backup. For troubleshooting purposes, we recommend that you do the former (set up as a new device) to avoid possibly reintroducing the same bug from the operating system image you saved.

Contact Apple support

As mentioned above, you should consider sending the device in if all troubleshooting mentioned above won’t work. Charging problems can sometimes be caused by a bad battery or malfunctioning power management IC. Only a technician can confirm whether your issue has bad hardware or not.

Problem 2: iPhone 8 stops charging after accidental drop, won’t turn on at all

Just dropped my iPhone 8, and the phone wont turn on or charge, it seems. The phone was at 2% and as I made my way to charge it, I accidentally dropped it (not a dramatic drop, screen didn’t break.) I proceeded to charge my phone, and I heard the tone the phone plays once it starts charging, and even though the screen is black, I know the phone is still on because I can still see the blue-light rays that the screen emits. After attempting to charge my phone (which took about five seconds), I wasn’t successful and I’m not sure if there is a problem with the battery or perhaps with the screen. — Alfred

Solution: Hi Alfred. If the only thing that happened on your iPhone before it started showing the issue was the accidental drop, then you have a bad hardware issue at hand. If your iPhone shows indications that it still charges, or if it is still making sound notifications from time to time, then the problem must have something to do with the screen. The drop may have damaged the board or the screen itself, rendering it useless at this time. It’s possible that there may also be a battery issue causing the trouble. In any of these scenarios, you need to let a professional check the device. There’s apparently nothing that you can do much if your phone won’t turn on at all.
