Problem 1: iPhone 7 draining battery fast, charges very slowly

My iPhone’s battery has been draining pretty fast, and it’s been happening since last Saturday (September 30). That Saturday, I charged to 90% before I left to go to an event that afternoon, and after it was over I turned to check my phone, and the battery dropped by 15% . When I came home that night, I charged my phone to 98% and then the next morning (Sunday, October 1st) , the battery was 25%. So I charged it again before I went to church, and I didn’t bring my phone with me. For the past 3 days, I have been trying to improve my battery life, by shutting off my phone or rebooting it.

Also when I reboot my phone, the side where the power button is gets really warm for some reason and I don’t understand why. Shutting off my phone and then turning it back on helps a little bit, and it gets warm when I normally use it. I’m assuming the problem has to do with the internal software on my phone, but I’m not quite sure. Is there any way to fix this problem? — Bethany

Solution: Hi Bethany. An issue like yours can be caused by either a software glitch, content (app) bug, or hardware malfunction such as a damaged battery or unknown motherboard problem. To see if it’s a software or hardware problem, you can do some troubleshooting steps.

Recalibrate the battery

The first troubleshooting step that you want to do is to see if the software is not reading the true battery level. This can happen if the device has been operating for a long time without stop. To do this troubleshooting step, kindly do the following steps:

  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 iPhone 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 Apple logo appears.
  5. Use your iPhone until it completely ran out of power again.
  6. Repeat steps 1-5.

Do a factory reset

Should the phone continues its erratic behavior, the next logical troubleshooting step is by wiping the device and restoring all software settings back to their defaults. This is done by restoring your phone as a new device. Make sure not to restore from backup as that might re-introduce the same bug that possibly causes the problem.

  1. Create a backup of your files. You can do that in a number of ways but the fastest and most effective way is by using iTunes in your PC or Mac. If you don’t want to create a backup at all, you can simply erase everything on the phone by following the steps in this link.
  2. Connect your iPhone to your computer with the cable that came with your phone.
  3. We assume you remember your phone’s passcode so simply enter it when you’re prompted for it.
  4. Select your iPhone once iTunes asks you for the specific device.
  5. Once you’re in the Summary panel or screen, select the option that will restore your device (Restore).
  6. Confirm by clicking on Restore button.
  7. Wait for a few moments while iTunes restores your device to its factory settings. It may also take some time if iTunes will need to install an updated operating system version.
  8. After this factory reset, all software settings should be restored to their defaults.
  9. Observe how the phone works when there are no apps installed.

Use another USB charging cable and adapter

In case the issue has to do with the accessories you’re using, make sure to use another known working charging set. If you have another iOS device with its own USB cable and adapter, use them to charge your iPhone 7 and see if it will make any difference.

Contact Apple

Should the issue continues after doing all the steps above, you can assume there must be a hardware malfunction behind it. You should send the phone in so Apple can repair or replace it.

Problem 2: iPhone 7 error 9 when trying to restore, won’t recover after accidental drop

I have an iPhone 7. It’s detected by itunes and only has the restore option and SN is not detected. It will not recover. The phone was dropped and the bottom of the case was bent. The phone did continue to work and only had a problem where it will not detect the SIM card because of the bent bottom case assembly. I tried to pull out the sim and the screen went black. I put in a new bottom case and it’s started the error 9 issue when trying to restore. I like to recover the data on the phone. (photos; contacts; notepad) and fix if. Let me know how much it will cost to do this? There is a slight dent on the motherboard but it did work without a problem after it was dropped. — Ray

Solution: Hi Ray. We don’t do hardware repair so we can’t provide an accurate cost for repair. Repair fees vary by shops so the best thing that you can do is to gather information yourself by contacting nearby shops in your area. Keep in mind though that data recovery depends on the damage on your phone and whether or not it still functions well enough to allow a computer to access its memory. If the microUSB port was damaged badly and a computer can’t access the memory at all, you’re out of luck. There’s no magic trick that will help you get those data from the phone. To know if the phone can still be fixed, have a professional take a look at the hardware.

Problem 3: iPhone 7 stuck in Apple logo screen

Hello. My husband’s phone has been stuck on the Apple logo for hours now after he was trying to update an app. It hasn’t been able to go past the Apple logo screen since. We have tried a hard reset, we tried taking it to the Verizon store and they said that there was nothing that could be done other than switching the SIM cards between the phones and trying to restore it through the computer and that didn’t work. The phone still stayed on the Apple logo screen.

We tried restoring it through iCloud and iTunes but that wasn’t successful either. Any other help or advice will be greatly appreciated because we really don’t want to buy a new phone but will if that is our only option. This is our last resort. Thank you. — Alikat993

Solution: Hi Alikat993. Looks like you have a really serious hardware malfunction here. Consider doing a complete recovery procedure via DFU mode and see if it helps. If it doesn’t, we’re afraid you’ll have to let the phone go and just buy a new one.

Recovery via DFU mode requires a computer with the latest iTunes program installed. If you already have that, here are the steps on what you need to do:

  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.

Problem 4: iPhone 7 plus won’t restore, keeps showing error 9 during recovery

New iPhone 7 Plus. Just switched 5 days ago from the same phone from Sprint (lousy) to T-Mobile (awesome, except this phone doesn’t work). Restored and it worked for an hour. Crashed. Apple logo came up, stayed on Apple logo indefinitely. Restored it from iCloud backup again (that’s what I did the first time). Worked an hour or so, crashed again, same thing: goes to Apple logo, never goes beyond that screen. So, I restored to factory settings…. worked for 24 to 48 hours. Crashed a little while ago. Now I can’t even restore to factory settings. I get an error 9 in iTunes on MacBook Pro running 10.12.6 and iTunes The phone is in restore mode (line of code at the top of the screen: “support.apple.com/iphone/restore” and the logo with the lightning cable pointed up at the iTunes app logo is on the screen) and it goes through: Extracting software; Preparing iPhone for restore; waiting for iPhone; verifying iPhone restore with apple; verifying iPhone restore; (Serial number: n/a) then I get the error message: “The iPhone “iPhone” could not be restored. An unknown error occurred. (9) I’ve used several cables. None of them apple-certified. If I could get my hands on an apple certified cable right now, I would. Help would be awesome. — Frank

Solution: Hi Frank. Error 9 during an update or restore is an indication that iOS can’t get further command from iTunes to continue with the procedure. This can occur if the phone is physically detached from the computer, or if there’s something that causes iTunes to lose sync with the phone. To see if the issue can be fixed at your level, try the following:

  1. Disconnect the phone from your computer.
  2. Press and hold both the Side and Volume Down buttons for at least 10 seconds, until you see the Apple logo.
  3. After that, connect the device to your computer again.
  4. When iTunes asks you to update or restore, click Update (not Restore) to reinstall iOS and keep your personal data.

If the issue continues, you can do these:

  1. Try to restore your device using another USB cable.
  2. Try to restore your device on another computer.
