    My iPhone 7 Plus Is Not Charging

    You plugged your iPhone 7 Plus into your computer or wall charger, but it is not charging. Your iPhone 7 Plus’s charging process involves four components: the software, charging port on the iPhone 7 Plus, charging cable, and charger. In this article, I’ll show you how to determine why your iPhone 7 Plus is not charging and walk you step-by-step through how to fix your iPhone 7 Plus, for good.

    Do I Need To Replace My iPhone Battery?

    No! In fact, replacing the the battery of your iPhone 7 Plus will almost certainly have no effect. More often than not, charging problems occur because of a software issue. The software, not the hardware, of your iPhone 7 Plus controls whether or not your it will charge when you plug it into a charger. In fact, your charging port is not even connected directly to the battery inside your iPhone.

    Why Would My iPhone's Software Stop It From Charging?

    Remember, the software of your iPhone 7 Plus starts the charging process when it detects that it is connected to a power source. Your iPhone 7 Plus may just look like it’s not charging because the software may have crashed while the screen was off. The charging process can’t begin if your software isn’t working correctly.

    Right now, we can’t be sure whether or not you have a software or hardware issue. We’ve assembled a step-by-step guide that will help you diagnose and fix  your problem, starting with a simple software and hardware fixes as well as a few repair options if your iPhone 7 is not charging.

    Troubleshooting Steps When An iPhone 7 Plus Is Not Charging


    1. Hard Reset Your iPhone

    A hard reset forces your iPhone to turn off abruptly and turn back on immediately. It’s kind of like turning a desktop computer off by pulling the cord out of the wall.

    Even though it’s not always a good idea to do, a hard reset is a go-to move for Apple technicians, especially when an iPhone is unresponsive. It’s the iPhone equivalent of the tried and true repair method of “unplug it and plug it back in.”

    Why Should I Hard Reset My iPhone?

    A hard reset is usually a temporary solution to a software problem. It doesn’t change anything at all — it just forces your iPhone to start from scratch, and often times the problem comes back.

    How Do I Hard Reset My iPhone?

    Press and hold the power button and the volume down button together until the screen goes blank and the Apple logo appears on the screen.
    When the Apple logo reappears, let go of both buttons.
    When your iPhone turns back on, the hard reset is complete.

    Pro Tips

    • Don’t give up too soon if nothing happens! Hold both buttons down for at least 20 seconds before you give up. A few extra seconds here could save you a trip to the Apple Store.
    • You should only do a hard reset when absolutely necessary, because software corruption problems can occur when a hard reset occurs while the iPhone is doing something important, like saving a file.
    • In Apple jargon, the power button is also know as the Sleep / Wake button.
    • Make sure you’re holding the volume down button — holding the volume up button won’t hard reset your iPhone!

    2. Inspect Your iPhone's Charging Port (Lightning Port)

    You should frequently inspect your Lightning port, also known as the charging port, to make sure it is clean. Lint, gunk, and other debris can prevent your Lightning port from making a solid connection with your Lightning cable.

    How Do I Inspect My iPhone's Charging Port (Lightning Port)?

    Use a flashlight to see if there is lint, gunk, or any other debris in your iPhone’s Lightning port.
    If you find debris in your iPhone’s Lightning port, gently brush it out with a new toothbrush or anti-static brush.

    Pro Tips

    • Do not brush out your device with anything that will conduct an electric charge or damage the electronics in the bottom of your device.
    • The Lightning cable has nine connectors. If any one of those connectors is blocked by debris, your device may not charge at all.
    • Often times, a dirty charging port will cause your iPhone to get stuck in headphones mode. Read our guide to more about this problem and how to clean your charging port.

    3. Inspect Your iPhone Cable (Lightning Cable)

    Just to clear up any confusion before we begin, Apple’s name for the iPhone charging cable is a Lightning cable. On one end, the Lightning cable has a Lightning connector that connects to the Lightning port on iPhones, iPads, iPods, and the AirPods Charging Case. On the other end is a USB connector that plugs into wall chargers, computers, and car chargers to charge Apple devices and sync them devices with computers.

    Why Should I Inspect My iPhone Cable (Lightning Cable)?

    Damaged Lightning cables are a common reason for iPhone problems, especially related to charging and transferring data between iPhones and computers.

    Lightning cables can be tricky to diagnose because when they start to go, they usually don’t break all at once. Sometimes an iPhone will continue to charge but won’t sync data properly, or vice versa, because of the construction of the cable. Make sure to take a close look while you’re troubleshooting!

    How Do I Inspect My iPhone Cable (Lightning Cable)?

    1. Use a flashlight and look closely at both ends of your Lightning cable. These cables can become worn and tend to fray, especially at the end with the Lightning connector.
    2. If you see no visible signs of damage, try charging your device using both a USB port on a computer and the wall adapter which came with your iPhone. If your Lightning cable works with one, but not the other, then your cable is not the problem.
    3. Try charging your device with a friend’s or family member’s Lightning cable. If their cable works while yours doesn’t, then you’ve identified that the problem is your Lightning cable.

    Pro Tips

    • If your iPhone or other Apple device is still under warranty, your Lightning cable is too! You can make an appointment at the Genius Bar or set up an online repair for a Lightning cable, just like you can with your iPhone.
    • Be very careful about buying low-quality third-party iPhone charging cables, like the ones you find in the gas station. Apple has a special MFi certification that you should look for before you purchase any non-Apple cable.
    • Now that you’ve been warned about low-quality cables, there are high-quality alternatives to Apple cables. One of my favorites (and the one I use in bed) is this 6-foot AmazonBasics Lightning Cable that is less than half the price of Apple’s. It’s MFi-certified so you know it’s high-quality, and it’s backed by Amazon’s 1 year warranty.

    4. Inspect Your iPhone Charger

    There are many different ways to charge your iPhone — plugging it into your laptop, wall adapter, car charger, and more. As a precautionary measure, the software of your iPhone will prevent charging if it detects fluctuations from the power source.

    How Do I Inspect My iPhone Charger?

    1. Charge your iPhone with multiple different power sources. If you normally use your wall charger, try using a USB port on your laptop, and vice versa.
    2. If your iPhone charges with one power source but not the other, then you know that the charger is causing your problem.

    Pro Tips

    • If you’re attempting to charge your iPhone using a USB hub or Apple keyboard, plug your iPhone directly into the USB port on your computer. USB hubs and keyboards only have certain amount of power which has to distributed between any of the devices connected to them. If the other devices connected to your USB hub or keyboard are using up too much power, then there may not be enough left to charge your iPhone.

    5. DFU Restore Your iPhone

    A DFU (Device Firmware Update) restore is most in-depth reset you can do to an iPhone. A DFU restore uses your computer to erase and reload all the code that controls both the software and hardware on your iPhone.

    Why Should I DFU Restore My iPhone?

    A DFU restore has the potential to fix software problems by completely erasing the code which may be causing your problem. The code is rewritten as if  your iPhone is brand new, so the software problem may get solved.

    Think of it like a house that has cracks in the foundation. Rather than try and fix the cracks, we are building an entirely new foundation.

    How Do I DFU Restore My iPhone?


    1. Using a Lightning cable, plug your iPhone into a USB port on your computer.
    2. Open iTunes. It doesn’t matter if your iPhone is on or off.
    3. On an iPhone 7 or newer, press and hold the power and volume down button.  
    4. After 8 seconds, release the Power Button, but continue to hold the volume down button
    5. Let go of the volume down button when iTunes says “iTunes has detected an iPhone in recovery mode.”
    6. Your iPhone’s display will be completely black if you’ve successfully entered DFU mode. If it’s not, try again from the beginning.
    7. Restore your iPhone using iTunes.

    Pro Tips

    • If you can, back up your iPhone before completing a DFU restore. Any time you do a restore, it erases everything from your iPhone. However, after the restore is completed, you restore all your backed up data back onto your iPhone.
    • Learn more about DFU restores in our article: How To Put An iPhone Into DFU Mode, The Apple Way.
    • A damaged component can prevent your iPhone from fully completing the DFU restore. If your iPhone is damaged in any way, a DFU may break your iPhone.
    • In Apple jargon, the power button is also known as the Sleep / Wake Button.

    6. Repair Your iPhone With Apple

    Apple repairs iPhones at the Genius Bar in Apple Stores and through their online mail-in repair service. Apple repairs are high-quality, but out-of-warranty repairs can be much more expensive than third-party solutions. If you’re looking to save some money you’re not covered by Apple’s warranty, you may want to check out our other recommendations.

    How To Repair Your iPhone With Apple’s Mail-In Service

    1. Visit Apple’s support website to begin the online mail-in repair process.
    2. Alternatively, call 1-800-MY-APPLE (1-800-692-7753) to set up a repair.

    How To Repair Your iPhone At The Genius Bar Inside Your Local Apple Store

    1. Visit Apple’s website to make a Genius Bar appointment before you go into the store. Apple Stores are extremely busy, and if you don’t have an appointment, you may have to wait for hours or end up being turned away. (Editor’s note: I’m a former Apple tech and we’re not exaggerating — please, do yourself a favor and make an appointment first!)
    2. When you arrive, go to the Genius Bar to check in for your appointment.
    3. Genius Bar appointments always include free diagnosis. If you’re under warranty, many repairs can be done on the spot, but it all depends upon which parts are in stock. If you’re not under warranty, the Genius will give you a quote for the cost of a repair.

    Pro Tips

    • If you’re not sure whether your iPhone is still under warranty, you can find out on Apple’s website.
    • Apple repairs are covered by a 90-day AppleCare warranty.
    • If you’ve ever used a 3rd-party service to repair your iPhone, or if you’ve ever replaced a part of your iPhone with a non-Apple part, then the Apple Store may not repair your iPhone.
    • In some cases, Apple will not repair devices that are older than five years old. These devices are classified as vintage or legacy.
