Your iPhone 7 isn’t charging and you don’t know how to fix it. When you have a charging issue with your iPhone, there’s a problem with one of these four components: the charging port on your iPhone 7, the charger cable, the iPhone’s software, or the charger itself. In this article, I’ll show you why your iPhone 7 won’t charge and walk you step-by-step through how to fix the charging problem for good.
Does My iPhone 7 Need A New Battery?
No! The truth is that 99% of the time, the battery has nothing to do with the charging problem, and replacing the battery inside of your iPhone 7 would probably have zero effect. Here’s why:
Your iPhone 7 won’t charge because the software crashed or there’s a problem with your iPhone’s hardware. Usually, the problem is software-related and can be fixed with a simple hard reset. The software of your iPhone 7 is the ultimate decider of whether or not your battery will begin to charge when you plug it in.
Are You Sure Your iPhone 7 Won’t Charge? Or Is It This…
It’s possible that the software of your iPhone 7 crashed while your screen was off, which makes it look like your iPhone 7 won’t charge. The screen is black, and it stays black when you plug it into the wall. But consider this: What if your iPhone battery is fully charged and the iPhone software froze on a black screen? The result would be the same. We’ll talk about how to fix that problem in the first step of the troubleshooting section.
About The iPhone 7 Charging Process
The charging process begins when the software detects that your iPhone 7 has been plugged into a power source like the wall adapter, your computer, or your car. We’ll walk you through the troubleshooting process for both software and hardware problems, and if you still have a problem (we hope you won’t), we’ll recommend some repair options in addition to Apple Support that could save you a lot of money.
How To Fix An iPhone 7 That Won't Charge
Your iPhone 7 isn't charging because you need to hard reset your iPhone, inspect your iPhone cable (Lightning cable), inspect your iPhone's charging port (Lightning port), inspect your iPhone charger, DFU restore your iPhone, explore repair option 1: Apple, explore repair option 2: CellSavers, explore repair option 3: iResQ, to fix the problem.
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 Home 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.
- A hard reset is just like taking a screenshot, but instead of tapping the buttons, you hold them down.
- 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.
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)?
- 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.
- 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.
- 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.
- 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.
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.
- 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.
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?
- 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.
- If your iPhone charges with one power source but not the other, then you know that the charger is causing your problem.
- 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.
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?
- Using a Lightning cable, plug your iPhone into a USB port on your computer.
- Open iTunes. It doesn’t matter if your iPhone is on or off.
- Press and hold the Power and Home Button together for 8 seconds.
- After 8 seconds, release the Power Button, but continue to hold the Home Button until iTunes says “iTunes has detected an iPhone in recovery mode.”
- Let go of the Home Button.
- Your iPhone’s display will be completely black if you’ve successfully entered DFU mode. If it’s not, try again from the beginning.
- Restore your iPhone using iTunes.
- 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.
