Problem 1: iPhone 7 stops charging, won’t turn on

Hi. So I had an iPhone 6S and I went to plug it in after it died and I got a black screen, no red battery or anything. I took it to a phone repair company and they told me it was a little chip inside the phone. It was an old phone and an old battery. I’m away at college so I had to upgrade in order (to iPhone 7) to contact my family and tell them what was going on. I just got back home from class and my phone was dead so I plug it in and the red battery was there. I waited for it to turn back on and it didn’t so I check it again and the red battery was gone. I tried restarting it, moving outlets everything. This phone is less than 8 hours old and I’m using the new cord and everything. I don’t understand what’s going on. — Krr0003

Solution: Hi Krr0003. There are a few reasons that we can think of that may have caused the problem in both of your iPhone 6 and iPhone 7.

Replacement phone is defective

If your iPhone 7 is not brand new, there’s a chance that you may have received a defective device. Consider returning it to the store where you got it from instead of fixing it. Unless you’re extremely unlucky, we don’t think this issue happen by chance. The best thing that you can do is to simply bring it back and save yourself from hassle.

Power outlets are defective/provides unstable voltage

If you have a brand new iPhone 7 and it suffered the same exact symptom as the previous phone after charging it, there’s a big chance that the problem is being caused by something outside the phone. For example, you may be using a bad power outlet when charging and that damaged the power management IC of both devices. Be sure to use a known working outlet when charging. Try charging in a different house or building and see if your phone turns back on.

Bad content in both phones

Another possible reason for your problem can be a bad app. If you restored your old backup to your iPhone 7, there’s a chance that you may have added a bad app from your old phone to the current one, causing the same exact problem. The thing is, you need to turn the phone on in order to check this. Unless you can power the phone back on, there’s very little to nothing that you can do.

Same software bug migration

Just as bad apps can be carried over to your new phone, restoring from old backup can also bring a possible operating system bug. To check, you must first find a way to turn the phone back on, or at least charge it so you can attempt a DFU mode update. If you haven’t tried it yet, connect your iPhone to a laptop or computer and see if it charges it. Alternatively, try to charge it in a different location using a known working charging cable and adapter. If it starts to show signs that it’s charging like red charging light, let it charge for at least 30 minutes. After that, do the following steps:

  1. In your computer, close all active apps.
  2. Open iTunes.
  3. Turn off your iPhone. If you can’t turn it off normally, let the battery drain to 0% so the phone powers down on its own. Charge the phone for at least an hour without attempting to turn it on.
  4. Connect your iPhone to the computer via USB cable.
  5. Press and hold the Power button for at least 3 seconds.
  6. Press and hold the Volume Down button on the left side of the iPhone while continuing to hold the Power button. Be sure to hold both Power and Volume Down keys for 10 seconds. If Apple logo appears at this time, repeat steps 5 and 6. Apple logo should not show at all.
  7. Continue to hold Volume Down key for another 5 seconds. If the Plug into iTunes screen is displayed, repeat steps 5-7. Plug into iTunes screen should not show up.
  8. You’ll know that your phone is in DFU mode if the screen remains black. Your computer should then tell you that iTunes has detected an iPhone.
  9. Follow the on-screen steps in your computer to do a full recovery.

Bring the phone back to the store or contact Apple for support

If the phone remains unresponsive, won’t charge at all, or fails to power back on after attempting a DFU mode update, your first choice, as mentioned above, is to bring it back to the store. If possible, you can also contact Apple so you can schedule a repair.

Problem 2: iPhone 7 Plus won’t respond, screen is frozen

I had my screen on my iPhone 7 Plus replaced because it was cracked. This is the third time I’ve done this, over the time of me having the phone. now after about a week of having it work fine it’s like the screen is Frozen. The phone comes on but when it ask for my password I can’t press anything because the whole phone is frozen. I just was wondering what I should do. All my photos of my son and my recently deceased husband are in my phone so I’m freaking out. Thank you. — Michelle L Avila

Solution: Hi Michelle. Smartphones like an iPhone 7 freezes or becomes unresponsive from time to time. This usually happens if the device has been running for a long time without stop. Sometimes, lack of or insufficient memory can temporarily cause an iPhone to become unresponsive. As long as they occur sparingly and the phone was never physically damaged, you should be able to do a soft reset to fix it. Soft reset (turning the phone on and off) is like the restart option in your computer. Here’s how to do it:

  1. Press and hold the Power button (located on the top right edge) until “slide to power off” appears then release.
  2. Slide the Power switch right. Allow several seconds for the device to power off.
  3. With the device powered off, press and hold the Power button until the Apple logo appears then release.

If the usual soft reset won’t work at all, you can then try the following steps:

  1. Press and hold the Power button.
  2. Continue to hold the Power button and press and hold the Volume down button located on the left side of your iPhone.
  3. Hold both buttons as the iPhone powers off and back on; release both buttons when the Apple logo appears on the screen.

If the phone still remains unresponsive, you should then try the DFU Mode update. Steps are provided above.

Keep in mind that you can only recover any files from the phone if it boots normally. Unless your iPhone turns on normally, your photos in that device are good as gone.

Problem 3: iPhone 7 turns on but screen stays black

I dropped my phone on a hard tiled surface this morning. I picked it up and was thankful to see no cracks but a completely black screen. I plugged it into my Mac in an attempt to restart it after pressing home/lock buttons did nothing. My Mac got me to restore the phone entirely to a new update. Even after the new update, the phone was unresponsive with no sounds and nothing on the screen. It’s been a few hours and still no response from the phone regarding sounds/display despite how many times I try to hold the home/lock buttons to restart. — Hayley Wren

Solution: Hi Hayley. You can’t fix physical damage by doing software solutions. Tweaking some software settings won’t do any good. Your phone has obviously suffered a serious hardware damage and the screen may have gone bad for good. The lack of cracks does not necessarily mean the screen is okay. A thorough hardware check is needed to assess the hardware damage. Only then can you know if the phone can still work normally or not. We suggest that you contact Apple so their technician can perform the necessary assessment. If you’re lucky and the issue is only isolated to the screen, replacing it should be a relatively easy fix. If more components were damaged, a more expensive motherboard replacement may be necessary.

Problem 4: iPhone 7 cracked screen turns to black

I bought a second hand iPhone 7 plus with someone cracked screen. I ordered a LCD replacement from a company called Puls, they are professional technicians who can fix iphones. I did the replacement in September 21, 2017. My phone was working completely fine. Up until 2 days ago, I dropped it twice and after my phone just randomly went black on the screen, it was still working because I could hear my messages notifications and feel the the vibration of the phone. I just wasn’t able to see the screen. I restarted my phone, and it was doing fine for the night. The next day ito continued to do the same thing, and I repeated the same thing I did, the previous night and it was working fine, today which is the third day, it has been getting out of control, the screen not only goes black, it also flickers, it turns on and goes black uncontrollably. I try pressing around the camera and flashlight and that’s exactly what’s making the phone go black. Whenever I press around that area, the phone goes black and it flickers. I was wondering if you can please help me resolve the issue. — Johanna Quintanilla

Solution: Hi Johanna. We don’t know what exactly you’re expecting from us. If you haven’t noticed, our blog is here to provide software solutions. Your case is obviously caused by a bad hardware so the least that you can do is to attempt another screen replacement. Before you reassemble everything, be sure also check the other components for obvious signs of damage. You should replace them as necessary. If a new screen replacement won’t work, let a professional run a detailed hardware diagnostics so other components can be checked.
