Your iPhone usually won’t charge because of a dirty port, a damaged or uncertified cable, a weak power source, or a temporary safety pause for liquid or temperature. Try a different cable and wall adapter, clean the port gently with a wooden toothpick, then force restart. If nothing works after 30 minutes on a known-good charger, book service.

The 2-Minute Checks That Fix Most iPhones

Work through these in order. Apple’s own advice is to try again after each step, and to let the phone charge for about half an hour before judging the result. Apple suggests plugging into a computer, a power accessory, or a wall outlet, restarting the phone, inspecting the cable and adapter for damage, and trying a different outlet. 

• Switch power sources. Try a wall outlet you know works. A weak source can stall a charge. Older laptops can have low-powered USB ports that won’t charge an iPhone effectively. 
• Inspect the cable and adapter. Look for fraying, bent prongs, or scorch marks. Don’t use damaged accessories.
• Look into the port. Shine a flashlight inside. Lint is the most common culprit (cleaning steps are below).
• Restart your iPhone. A normal restart clears many small glitches.
• Wait 30 minutes. A very drained phone can take a little while to show signs of life. One guide notes the charging symbol can take a few minutes to appear on a fully drained iPhone. 
• Force restart. If the screen is black or shows only a battery icon, do this next.

How to Force Restart Any iPhone

For iPhone 8 and newer (which covers every iPhone that supports iOS 27), press and release Volume Up, press and release Volume Down, then hold the side button until the Apple logo appears. A force restart doesn’t erase anything. 

For older models: on iPhone 7 and 7 Plus, hold the side button and Volume Down together. On iPhone 6s and earlier, hold the side (or top) button and the Home button together.

After the Apple logo appears, give the phone another half hour on the charger. 

Cable, Charger, or iPhone? The Swap-One Test

Here’s the mistake most people make: they change three things at once, so they never learn which one was broken. Use the Swap-One Test instead. Change one thing at a time and watch the result.

Step	Swap this	If it now charges, the problem is…
1	The cable (use one you know works on another device)	The old cable
2	The wall adapter (keep the new cable)	The old adapter
3	The outlet or power source	The outlet, power strip, or computer port
4	Test your cable and adapter on another phone	If they work there but not on yours, it’s your iPhone

Why it works: each swap rules out exactly one suspect. If every accessory is proven good and your phone still won’t take a charge, you’ve narrowed it to the port, the battery, or the software. That’s valuable information if you do end up at a repair counter.

One more quick test: try wireless charging. If your iPhone charges wirelessly but not by cable, the port may be damaged. 

USB-C or Lightning: What Does Your iPhone Need?

Not every guide tells you which port you have, and it matters when you’re buying a replacement.

iPhone model	Port
iPhone 15 and newer (including iPhone 16, 17 and iPhone Air)	USB-C
iPhone 14 and older, and iPhone SE (3rd generation)	Lightning

Three practical rules:

• Match the cable to the port. A USB-C cable won’t fit a Lightning iPhone, and vice versa.
• Buy certified. Anker’s guide warns that iOS won’t draw power from damaged or uncertified gear. Look for “MFi” (Made for iPhone) on Lightning accessories, and buy USB-C cables and adapters from reputable brands. 
• Use a wall adapter when in doubt. It’s the most reliable power source for a stubborn phone.

Why Does My iPhone Say “Liquid Detected”?

This alert means your iPhone sensed moisture and stopped charging on purpose to protect itself. Apple says the alert can come from liquid in the Lightning or USB-C connector, or on the cable or accessory. The exact wording varies by model. 

Here’s what to do:

• Unplug everything. Don’t keep trying.
• Dry the phone. Apple suggests gently tapping the iPhone against your hand with the connector facing down. 
• Wait. One guide says to let the port dry naturally for at least 30 minutes, with no heat or compressed air. If the alert persists, some guides advise allowing up to 24 hours. 
• Try wireless charging. Apple notes you can still charge with a wireless charger. 
• Only in a real emergency, use the override. If you reconnect the cable, you’ll get an option to override the detection and charge anyway. Charging a wet port is risky, and it can corrode the connector pins. 

Seeing the alert when nothing is wet? Apple says that if it happens with one particular cable, that cable may be damaged. If it happens with every Apple cable, you may need service. 

Why Won’t My iPhone Charge in the Cold?

If you live in Canada, this one is for you. Your iPhone has a comfort zone, and a January commute can leave it.

Apple says iPhones are designed for ambient temperatures between 0 and 35 degrees Celsius. Outside that range, a phone that gets too cold may not charge or could stop charging. You may see a Charging On Hold message on the Lock Screen. Apple explains that charging resumes once the device returns to a normal temperature. 

What to do:

• Warm it up gradually. Put it in an inner pocket or bring it indoors. Don’t blast it with a heater or hair dryer.
• Give it time. Apple says battery behaviour returns to normal when you bring the device back to warmer surroundings. 
• Don’t leave it in a cold car. A cold-soaked phone on a car charger is a common winter “mystery.”

The same rule works in reverse. When an iPhone gets too hot, charging, including wireless charging, can slow or stop. 

iPhone 17 or iPhone Air Won’t Charge From a Dead Battery?

This is a 2026-specific problem, and almost no guide covers it yet.

In April, users of the iPhone 17 lineup and iPhone Air began reporting that their phones wouldn’t respond to charging after the battery died completely. Some people saw no charging indicator after plugging in a USB-C cable, and found a MagSafe charger brought the phone back after 10 to 15 minutes. 

Apple fixed it in a small software update. iOS 26.5.1 addresses an issue for a small number of users that may prevent wired charging on iPhone Air and iPhone 17 models when the battery is nearly drained. 

What to do if it’s your phone:

• Use a wireless or MagSafe charger and leave it for 15 minutes or more.
• Once it boots, update iOS (Settings > General > Software Update).
• Still stuck after updating? Run the Swap-One Test, then book service.

Why Does My iPhone Stop at 80%?

Usually, nothing is broken. Your iPhone is doing this on purpose.

• Optimized Battery Charging. Apple says it uses on-device learning to understand your routine, then waits to finish charging past 80 percent until you need the phone. 
• Heat. If the battery gets too warm, software can limit charging above 80 percent until it cools. Move the phone somewhere cooler. 
• A charge limit. iPhone 15 models and later may have a charge limit that stops charging at a level you set. 

To charge fully, go to Settings > Battery > Battery Health & Charging and turn off Optimized Battery Charging and any 80% limit. Labels shift slightly between iOS versions, so look under the Battery settings if you don’t see those exact names. 

Slow Charging vs. Not Charging at All

Slow charging is a different problem with a different list of suspects:

• A low-power adapter or port. Switch to a proper wall adapter.
• Heat. A warm phone charges more slowly.
• A dirty port. A partial connection can mean a weak charge.
• An aging battery. Asurion’s guidance is to try a certified fast charger, close background apps, clean the port, and consider a battery replacement if it’s still slow. 

Wireless or MagSafe Not Working

Wireless charging is a handy diagnostic tool, but it has its own failure modes:

• Alignment. With standard Qi chargers the phone has to sit just right, and even slight misalignment can stop charging. 
• Your case. Thick cases, especially metal ones, can weaken or block the connection. Take the case off and try again. 
• Use magnets. Certified MagSafe or Qi2 chargers snap the phone into position. 

Wireless charging works on iPhone 8 and newer. If wireless works and wired doesn’t, suspect the port or cable. If the reverse is true, suspect alignment or your case.

Charging Stopped After an iOS Update?

iOS 27 is now rolling out to iPhone 11 models and newer. Two different things can happen after a big update, and it helps to tell them apart. 

1. “It charges, but my battery seems to drain.” That’s usually normal. Apple says a major update can temporarily affect battery life and thermal performance. The extra work typically shows up in the first 24 to 48 hours and can last two or three days. Leaving the phone plugged in overnight on Wi-Fi helps it finish. 

2. “It won’t charge at all.” Try this order:

• Force restart. In Apple’s community forums, one user reported that a force restart got a phone charging again after an iOS 26.2 update. That’s one person’s experience, not a guarantee, but it costs nothing to try. 
• Check for a newer update in Settings > General > Software Update.
• Run the Swap-One Test to rule out a coincidence with a failing cable.

How to Clean the Port Safely

Dust and pocket lint pack into the port over time and block the connection. Cleaning it is the single most common fix for the “wiggle the cable” symptom.

Do	Don’t
Turn the phone off first	Use metal pins, paperclips or needles
Use a wooden toothpick or soft, dry brush	Use liquids
Work gently and shine a light inside	Blast it with compressed air
Plug the cable in firmly afterward	Force anything in

On compressed air, here’s the honest picture. Anker’s guide acknowledges that Apple advises against it, but notes many people use it anyway. Given the risk to internal parts, skip it. A toothpick is cheaper and safer. 

Is It the Battery? Check Battery Health

A worn battery can make charging erratic. To check, go to Settings > Battery > Battery Health & Charging and look at Maximum Capacity. One guide says a figure below 80% may mean the battery needs replacing. 

How to tell battery from port:

• Port or cable problem: the phone charges when you wiggle the cable, or other cables behave the same way.
• Battery problem: the phone charges, but the percentage drops fast or it shuts off unexpectedly.

If you have an AppleCare plan, Apple’s Canadian page says battery service is at no extra charge if capacity falls below 80%.

Software Last Resorts: Reset, Then Restore

If hardware tests out fine, software is the remaining suspect. Go from gentle to drastic:

• Reset All Settings. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This won’t erase your data but restores default settings. 
• Back up your iPhone.
• Restore from a computer. Connect your iPhone to a Mac or a Windows PC and use the update or restore option. Choose Update first, since it keeps your data. Restoring erases the phone, so only use it with a backup. Follow Apple’s own on-screen steps for your computer.

If a restore doesn’t help, it’s almost certainly hardware.

“Accessory Not Supported” and Fake Cables

This message means your iPhone doesn’t trust what’s plugged in. Apple lists three typical reasons: a dirty or damaged port, a damaged accessory, or a USB charger not designed for charging devices. 

Apple’s fix list:

• Connect directly to the charger, with no adapters or extras in between.
• Clear debris from the port.
• Restart.
• Try a different cable or charger.
• Update iOS.

A very cheap, no-name cable is a prime suspect. Apple also publishes guidance on spotting counterfeit and uncertified accessories.

Repair Options in Canada

You’ve run the checks and your phone still won’t charge. Here’s the Canadian landscape.

Before you go, note that these are signs you need a pro: the phone charges only at certain angles, the port looks damaged, there are signs of water damage, or the battery drains unusually fast. 

Option	Good for	Notes
Apple Store / Apple Canada support	Diagnostics, genuine parts, warranty	Apple guarantees its service and parts for 90 days or the remaining Apple warranty, whichever is longer.
Apple Authorized Service Provider	Apple-certified repair closer to home	Authorized providers set their own fees, though AppleCare-covered fees are the same everywhere.
Independent repair shop	Speed and sometimes price	Ask what parts they use and what warranty they give
Apple Self Service Repair	Confident DIYers	It launched in Canada on August 19, 2025, with manuals, genuine parts and toolkit rental.

What does it cost? Apple’s Canadian pricing page didn’t load for me, so check Apple’s live page for your model. For a rough battery benchmark, one Vancouver repair shop’s guide puts Apple’s battery service at about $119 to $165 and independent shops at $99 to $233, depending on the model. That’s one source and batteries only, so treat it as a ballpark. Always get a written quote that includes the diagnostic fee, if any. 

For contact, Apple’s Canadian support line has been reported by users as 1-800-263-3394, but confirm it on Apple’s official contact page before calling.

What We See Most Often at WeFixAll

At WeFixAll, common iPhone charging issues can often be traced to faulty cables, unsuitable adapters, cold temperatures, or lint inside the charging port. For example, replacing a damaged cable with a working one may restore charging immediately. Similarly, an iPhone exposed to cold weather may need time to return to a normal temperature before charging resumes. If the charging cable only works at an angle, debris or damage inside the port could be responsible. Identifying these common causes can help determine whether a simple fix or professional iPhone repair is needed.

Conclusion

If your iPhone won’t charge, start by testing another cable, adapter, and power outlet. Check the charging port for visible debris, restart your device, and allow it to return to a safe temperature if a temperature alert appears. Avoid inserting sharp objects or using liquids to clean the port. If your iPhone still won’t charge after these checks, WeFixAll can help diagnose the issue and recommend a suitable repair. Request a repair estimate before proceeding with the service.

FAQs

Why is my iPhone not charging when plugged in?

The most common causes are a damaged or uncertified cable or adapter, a dirty port, or a weak power source. Less often it’s a software glitch, a liquid or temperature pause, or a worn battery. Run the Swap-One Test to find which one.

How do I clean my iPhone charging port safely?

Turn the phone off, shine a light inside, and gently remove lint with a wooden toothpick or soft dry brush. Never use metal, liquids, or compressed air.

Can a bad battery stop my iPhone from charging?

Yes. Asurion says a failing battery can make an iPhone refuse to charge or lose power quickly. Check Battery Health, and consider service if capacity is below 80%. 

Why does my iPhone stop charging at 80%?

It’s usually Optimized Battery Charging, a charge limit on iPhone 15 and newer, or heat. It isn’t a fault. You can change the settings under Battery.

What should I do if my iPhone says “Liquid Detected”?

Unplug it, dry the connector by gently tapping it, and wait. Use wireless charging if you need power, and only use the emergency override when you truly must. If the alert keeps appearing with an Apple cable, get it serviced.

Why won’t my iPhone charge after an iOS update?

Start with a force restart, then check for a newer update. If it charges but drains faster, that’s usually temporary background work after a big update.

How much does it cost to fix an iPhone that won’t charge in Canada?

It depends on the model and the cause. A cable swap costs little, while a battery or port repair costs more. Check Apple Canada’s live pricing and get a written quote from any shop.
