My iPhone refuses to charge properly, even though I plug it in to computer or power source using a standard charger, and that spells trouble.
Before entering into a full-blown panic mode, you first need to check three components involved with charging your iPhone:
- USB cable (depending on which iPhone you own)
- wall adapter
- charging port.
So, does this mean it’s time to get a new battery? Probably not! You may find it hard to believe but, when your iPhone won’t charge, most of the time it’s not the hardware but your iPhone’s software iOS at fault.
You’re not hooking your iPhone directly to a battery when you plug your iPhone into a power source – You’re actually hooking it up to a lightning or 30-pin dock connector port, and even that’s not connected directly to the battery! It’s the logic board together with your iPhone’s software that determines whether or not your battery will charge after power enters your iPhone.
Your iPhone device is a really complex piece of hardware, and although this may seem counter-intuitive, it’s the iPhone’s software and firmware that determine whether the battery will or won’t charge.
Replacing the battery will probably have no effect if your iPhone is not charging. If it is, in fact, a hardware problem that’s preventing your iPhone battery from charging, it’s highly likely that the problem lies with your charging port – not the iPhone battery itself.
iPhone Charging Port
There’s a very simple cause for one of the main reasons why an iPhone won’t charge; The iPhone’s port is probably clogged with debris, pocket lint, dust, or some other obstruction. The first thing you need to do is check your iPhone’s charging port and look for any build-up of dust or dirt, because it only needs to be something quite small to prevent a charging cable from fitting correctly into the iPhone.
Use a flashlight and take a closer look inside the bottom of your iPhone. If there’s any dust or dirt in there it could well be preventing the lightning or dock connector cable from making an accurate connection to your iPhone. There are many small pins in there and it only needs one obscured pin to prevent your iPhone from charging.
So, you need to brush out any lint, dust or other debris from the charging port of your iPhone. Here’s how we do it: Gently brush out the charging port of your iPhone by using a soft, new toothbrush.
Reboot Your iPhone
This is usually not required, but a reboot can sometimes resolve a software issue that, for whatever reason, refuses to acknowledge that the device is charging. Even though this is very rare, it can happen. If your iPhone battery is still not charging and you’ve tried all the above tips, force your iPhone to reboot by holding down both the Power and Home buttons until you see the Apple logo: it just may help.
Inspect USB Cable
Have a good look at the cable you’re using to charge your iPhone. Hint: Your iPhone uses Apple’s lightning cable for charging if your phone is an iPhone 5, or newer. Your iPhone uses the 30-pin dock connector cable to charge if you have an iPhone 4S or older.
If your iPhone is a recent purchase, remember that the USB cable that came with your iPhone is covered by your iPhone’s warranty, so Apple will probably replace your cable for free if your iPhone is still under warranty.
Low-quality third-party iPhone charger cables are another very common cause of iPhone charger problems. It’s true that Apple cables are expensive to purchase, but the cheap ones you buy at gas stations are just not the same high quality.
If you can’t visibly see any damage to the USB cable, try plugging into your computer’s USB port instead of the wall adapter that came with your iPhone. Perhaps you already use your computer to charge your iPhone, so try using the wall adapter instead. Obviously your cable is not the issue if it works in one place and not the other.
Alternatively, you might try using a friend’s cable to charge your iPhone. If you find that your iPhone is suddenly back in action after you’ve plugged it in, then you know that a faulty cable is the culprit: it’s the reason why your iPhone wouldn’t charge.
Try Changing the USB Port or Wall Outlet
Another reason why an iPhone won’t charge is due to where it’s actually plugged into. It can happen that the light switch is turned off or the wall outlet itself isn’t working, so change the outlet if you’re using a wall charger.
If you’re trying to charge your iPhone from a USB cable connected to your computer, it could well be that the USB port on the computer itself is the problem. Try again using another USB port on the computer and this will often fix the issue: it doesn’t matter whether it’s a PC or Mac.
