What’s the most important feature of any smartphone–including iPhones? It’s not the screen, the processor, or the camera. It’s the battery.
Why? Because if your smartphone’s battery isn’t in good working order, you’re not going to be able to use all those amazing features your smartphone has. Want proof of this? Just think about how your panicked when you found out your iPhone wasn’t charging. Within hours, or maybe minutes, your device would be completely useless.
So what are some of the reasons your iPhone might not be charging? We break down the 3 most common causes.
#1) Your Lightning Port Is Clogged
The #1 cause of an iPhone not charging is usually a clogged Lightning port. The Lightning port is one of the few openings an iPhone has, so its the natural place for dirt, dust, and lint from your pockets to accumulate.
When this happens, the debris is compacted at the bottom of the port and when you plus your Lightning cable into your iPhone’s Lightning port, it may look like you have a firm connection, but in reality, the power couplings that transfer energy to your iPhone’s battery aren’t connected.
Yes, the feeling of waking up in the morning only to see your iPhone hasn’t charged above the 15% battery level it had when you plugged it in at bedtime is horrifying.
The good news is a clogged Lightning port is pretty easy to unclog and once you do your battery should be able to charge again when you plug your iPhone into power. Here’s How To Clean Your Smartphone’s Lightning and USB-C Ports.
#2) Your Cable Or Charger Is Bad
But what if you’ve cleaned your Lightning port and your iPhone still won’t charge? The next most-likely culprit is a bad Lightning cable or a bad USB charger. If either the Lightning cable or USB charger is bad, you can’t fix them. Your only option is to pitch them and go out and buy a new one.
To find out if you have a bad charger or Lightning cable, you’ll have to inspect each on individually–and you’ll need an extra Lightning cable and USB charger to do this.
Start by using a different Lightning cable with the same USB charger you normally use. If your iPhone charges with the new Lightning cable, the problem was your old cable.
But if your iPhone doesn’t charge with the new Lightning cable either, it’s time to try a different USB charger. Try both your original and new Lightning cables with a new USB charger. If your iPhone charges on either cable with the new USB charger the problem was your old USB charger.
#3) Your Battery Is Shot
If you’ve cleaned your Lightning port and swapped Lightning cables and chargers but your iPhone still isn’t charging, bad news: your battery is probably bad–or worse, there’s a problem with your iPhone’s logic board.
If this is the case you’re only option is to take your iPhone to an Apple Store or authorized repair center and have the battery replaced, or have the logic board inspected.
What To Do If Your iPhone Just Won’t Charge No Matter What
Take it to an Apple Store or authorized repair center. This is especially true if you’ve cleaned the iPhone’s port and made sure your cable and charger are working fine. The most likely scenario as to why your iPhone battery isn’t charging is a bad battery itself.
And bad batteries can be dangerous, so see an iPhone specialist at an Apple Store or authorized repair center ASAP.
