Why Won't My iPhone Charge? (Quick Answer)
The most common reasons your iPhone won’t charge are a damaged cable, a dirty charging port, a bad outlet, or a small software glitch. Less often, it’s a failing battery or a broken charging port. Work through the fixes below in order. Most people solve it in the first three steps, so don’t panic if the first thing you try doesn’t work right away, and don’t assume the worst before you’ve gone through the full list.
8 Fixes to Try Right Now
1. Try a different cable
Cables wear out. Bending, twisting, and daily use can damage the wire inside even if it looks fine on the outside. A cable that gets wrapped tightly around a charger or stuffed into a bag every day is especially prone to this kind of hidden damage. Swap in another certified cable and see if that fixes it.
2. Try a different outlet or adapter
Plug straight into a wall outlet instead of a power strip or a computer USB port. Weak power strips or old surge protectors sometimes can’t deliver enough power to charge properly, especially if several devices are plugged into the same strip at once.
3. Clean the charging port
Lint and dust build up in your pocket or bag over time. This is one of the single biggest causes of charging failure that we see on the bench. We’ll cover exactly how to do this safely below, so don’t skip ahead and grab a random sharp object just yet.
4. Restart your iPhone
A simple restart clears small software glitches that can stop your phone from recognizing that it’s plugged in. It sounds almost too simple, but it genuinely resolves a good number of charging complaints on its own.
5. Check for software updates
Go to Settings, then General, then Software Update. An outdated iOS version can occasionally interfere with charging, particularly if you’ve been putting off an update notification for a while.
6. Remove your case
If your phone charges wirelessly but not with a cable, try taking off the case first. Thick cases or metal attachments can interfere with the connection, and some magnetic accessories can also cause interference with wireless charging pads.
7. Check for corrosion
Shine a flashlight into the port. Look for anything gray, brown, or crusty. That could be corrosion, often from earlier water exposure you might not even remember, like a splash at the sink or a rainy walk. Don’t try to dig it out yourself, this one needs a professional.
8. Test wireless charging
If your iPhone supports wireless charging, place it on a Qi-certified charger. If it charges wirelessly but not with a cable, the problem is almost certainly the port or the cable, not the battery, which helps narrow things down quickly.
How to Safely Clean Your Charging Port
Here’s how to do this the right way, step by step, without risking further damage to your phone.
- Turn off your iPhone completely before you start.
- Shine a flashlight into the port to look for lint or debris packed inside.
- Use a wooden or plastic pick, or a soft, dry, anti-static brush, to gently loosen debris from the edges.
- Gently tap the phone, port facing down, to let loose debris fall out on its own.
- A can of compressed air can help dislodge stubborn bits. Use short bursts rather than one long blast.
- Try charging again with a cable you know works well.
What not to use: metal tools of any kind, needles, paperclips, or toothpicks with metal tips. These can scratch the pins inside the port or bend them, turning a simple cleaning job into an expensive repair. Also avoid pushing anything too far into the port, since the connector pins sit close to the opening and can be bent with too much pressure.
Why Cables and Ports Fail So Often
It helps to understand why these two things cause so many charging headaches in the first place. Lightning and USB-C cables are built with thin wires bundled inside a flexible outer coating. Every time you bend the cable sharply near the connector, especially right where it plugs into your phone, you stress those internal wires a tiny bit. Do that hundreds of times over months of daily use, and eventually one of those wires can crack or separate, even though the outside of the cable looks perfectly normal.
This is why a cable that charges fine at one angle but not another is often more damaged than it looks. If you find yourself needing to hold the cable at a certain angle for it to work, that’s a clear sign it’s time to replace it rather than keep working around it.
Charging ports fail for a different reason. They’re small, open slots on the bottom of your phone, which means they’re constantly exposed to whatever is in your pocket or bag, lint, sand, crumbs, and general daily grime. Over months, that debris packs down tightly inside the port. Even a small amount can be enough to stop the cable’s connector from making full contact with the pins inside.
Is It an MFi-Certified Cable?
If you’re using a cheap or off-brand cable, that could be your whole problem. Apple’s MFi certification, which stands for Made for iPhone, means a cable has been tested to work safely and reliably with your device. Non-certified cables can be actively rejected by iOS, and you might see a message like “This accessory may not be supported,” even if the cable physically fits and seems to charge slowly.
Look for an MFi badge or a “Works with Apple” label on the packaging. If you bought your cable from a dollar store, a gas station, or an unfamiliar online seller, there’s a real chance it isn’t certified, even if it was sold as one. Genuine Apple cables and well-known third-party brands are safer bets, and they tend to last longer too.
Software or Hardware? How to Tell
Here’s the quickest way to figure out what you’re dealing with before deciding your next move.
What Happens | Likely Cause |
Wireless charging works, cable charging doesn’t | Charging port or cable |
Neither wireless nor cable charging works | Battery or software |
Phone charges only at certain cable angles | Charging port |
“Accessory not supported” message | Cable not certified, or port debris |
Battery drains fast even when it seems to charge | Battery health issue |
Charges fine after a restart | Software glitch, not hardware |
If wireless charging works but wired charging doesn’t, that’s a strong sign the port itself has a problem, not the battery. This single test can save you a lot of guesswork, since it isolates the issue to one specific part of the phone right away.
When the Port or Battery Needs Repair
A few signs point to something you can’t fix at home, no matter how many cables or outlets you try.
- The cable feels loose or wobbly in the port, even with a good, known-working cable
- You see corrosion inside the port when you shine a light in
- The phone shows a “Liquid Detected” alert repeatedly, even after drying it out
- Battery Health, found under Settings, then Battery, then Battery Health and Charging, shows Maximum Capacity below 80 percent
- Nothing works, wired or wireless, after trying every fix listed above
If you see a “Liquid Detected” message, unplug the cable right away, gently tap the phone with the port facing down, and leave it in a dry spot for a few hours before trying again. Don’t use a hairdryer or any external heat source, and don’t insert anything into the port to try to speed up drying, since that can push moisture further inside rather than out.
How to Prevent Future Charging Problems
A few simple habits can save you from dealing with this all over again in a few months.
- Buy MFi-certified cables. Stick to Apple originals or well-reviewed certified brands, even if they cost a little more upfront. Cheap cables tend to fail faster and can occasionally cause charging or software issues down the line.
- Avoid sharp bends. Try not to wrap your cable tightly around your charger or bend it at a hard angle right where it meets the connector. This is the single most common way cables get damaged internally.
- Check your pockets. If you regularly carry your phone loose in a pocket with change, lint, or sand, your port is going to collect debris faster. A slim case with a port cover, or simply being mindful of where you store your phone, helps a lot.
- Update iOS regularly. Software updates occasionally include fixes for charging-related bugs, so don’t ignore that notification for too long.
- Check battery health every few months. This takes 10 seconds and can catch a declining battery early, before it turns into a bigger problem or a phone that won’t hold a charge at all.
Following these steps won’t guarantee you’ll never have a charging issue again, but it does cut down on the most common causes significantly, and it means fewer surprise trips to a repair shop.
