Problem #1: iPhone 8 Plus won’t charge to 100%, screen showing lines at the bottom

Good day. I’m using an iPhone 8 Plus. Last night my phone turned 20% so i had to charge it. When it’s already in 88% the battery did not charge already, it is plugged in but the battery status is not increasing. My charging materials are fine. So i tried to hard restart the phone twice. On its first restart, I saw a horizontal line at the bottom of the screen and on its 2nd restart, I saw another line but half of the first horizontal line (that I saw on my first restart). — Sndar_13

Solution: Hi Sndar_13. Was your iPhone dropped, got wet, or exposed to elements before you noticed the screen and charging issues? If the answer is yes, then stop wasting your time looking for software solutions (which are the only ones you can do). Contact Apple and arrange a repair. There’s no software fix for bad hardware.

If your iPhone was never dropped nor exposed to water or elements (no physical damage that might damage the hardware), then follow our suggestions below.

Force restart your iPhone 8

The phone may have become unresponsive or has frozen for some reason. To reboot it, you need to do these steps:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Then, press and hold the Side button until you see the Apple logo.

Use another set of charging accessories

A defective charging cable or adapter can lead to problems or even damage a device. To check if you have an issue with the current set of charging materials, try using another known charging set. You can borrow your friend’s charging cable and adapter, charge using a computer, or go to a nearby Apple store and charge your iPhone there. If that won’t work or fix the problem, proceed to the next step.

Recalibrate the battery and iOS

Sometimes, your iPhone’s operating system may no longer be able to track the actual battery levels. This can sometimes happen if the device has been running for a long time, or if there’s something wrong with the battery. In some cases, recalibrating the operating system and the battery may help so be sure not to skip it. Here’s how to do it:

  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.

Factory reset your iPhone

There’s a chance your iPhone has a software problem. To check, you want to wipe it and restore its software to its defaults. This is most straightforward way to determining whether or not software has a hand in this trouble.

Factory reset will wipe your data (photos, videos, documents, etc) so be sure to back them up ahead of time. Once you’re ready, follow these steps to wipe your iPhone:

  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.

Problem #2: How much iPhone 8 screen repair with Apple?

My iPhone 8 screen was dropped, and it cracked and skidded. However, i was playing music at the time and it continued to play, and the phone vibrated when i got a call, so the phone itself works. However, when i try to turn it on, the screen only lights up to a dark navy and is unresponsive to touch screen. What is wrong with it and how much do you think it will cost at Apple to repair it? Is it just a cracked screen replacement? — Olivia

Solution: Hi Olivia. The symptoms you mention here are consistent with a broken screen so the best route to take is repair. Unresponsive touchscreen often occurs when the digitizer, a thin layer of sensor on top that captures your touches, is broken is disconnected. It’s very likely that the damage goes beyond the digitizer and may have affected the entire display assembly. To fix that, Apple will most probably use a new screen assembly instead of fixing each component piecemeal. If you have AppleCare+ on this device, Apple only charges 29 US dollars for a screen repair. If your phone has other damages, you’ll have to shell out 99 US dollars. If you don’t have AppleCare+, screen repair the usual screen repair fee for iPhone 8 is 149 US dollars and 349 US dollars with other damage. Other damage can be anything, including scratches, broken buttons, etc.

Problem #3: iPhone 8 keeps restarting, apps keep crashing, photos won’t show

Last August my phone kept messing up. Shutting off apps. Phone restarting. I’d click on pictures and they’re completely gone, then I wait a minute and it says restoring, and they come back. All of this several times a day. Then one day in September it fully took the pictures away. And continued the shutting down of apps. I called Apple who told me to update my phone. I had version 10.2.1 so I tried but it kept saying couldn’t be done. I connected it to three different internet sources, but couldn’t be done. I called Apple again who said to bring my phone into the store. The closest store is an hour away and I have been battling neurological issues with my son so there’s no way I have the time to drive that distance to get it looked at. So I factory reset my phone. Which killed me as I had photos of my child’s birth, and photos of my aunt who had passed away just a few months before. I reset it, tried updating again… and same message. However the apps were no longer clearing out and my pictures were staying. That lasted about 3 months and it’s doing it again. — Mary Lewis

Solution: Hi Mary. If the issue occurs randomly, it’s most likely caused by a software or an app bug. That the issue fade away after you factory reset your iPhone is another clear indicator that your device either has developed an operating system (iOS) problem for some reason, or one of your apps is problematic. Try to remember what you did before that might be the reason for the problem. For example, if you recently installed an app and the issue appeared to coincide with it, delete that app and see what happens.

You can also try to reset all settings to see if there’s some incorrect settings that might have caused the problem. Here’s how:

  1. From the Home screen, go to Settings>General>Reset.
  2. Tap Reset All Settings.
  3. If presented, enter the passcode.
  4. Tap Reset All Settings to confirm.

It may take some moments for the reset to complete so just let the phone finish the job.

If you reset all the settings, you are basically just forcing the phone to delete customizations that happen after it was unboxed. This process won’t delete your personal data such as photos, videos, etc. so it can be done safely. We still recommend that you back everything up though before doing it. After the phone has reset all settings to their defaults, check for the issue again.

If the problem stays, go ahead and do another round of factory reset.

Problem #4: iPhone 8 keeps freezing and refuses to work after accidental drop

I have a iPhone 8. I dropped my phone couple of months ago and the screen cracked. It was working fine first of all but then it started to freeze me & cant do nothing with it properly! I can’t ring nobody because it freezes for about 5 minutes. and I can’t hear nothing. I took it to apple who done a full diagnosis on the phone and reset it back to factory settings. It worked fine for 5 minutes & then went back to freezing and not working. Could it be because the screen or broke or is it a actual fault with the phone itself. — Katie

Solution: Hi Katie. Most probably the phone’s motherboard was damaged after that drop. Signs of damage need not be visible. Even if only the screen was expectedly cracked, it’s still possible that other components in the board suffered permanent damage too because of the trauma. We suggest that you talk to Apple so they can give you options. If they’ll discover that the phone is beyond economic repair, they’ll most likely give you a replacement. Depending on your phone’s warranty status, the repair fee may vary for you.
