Phone Not Charging? 8 Things to Check Before a Repair

If your phone won’t charge, the cause is often something simple: a worn cable, a weak adapter, lint packed into the charging port, or a phone that has paused charging because it’s too warm. Work through the checks below in order. Most take a minute or two, and they’ll tell you whether you need a repair at all.

1. Swap the cable, adapter and outlet

Cables take a beating. They get bent at the ends, stepped on and wound tightly into bags, and the damage is often inside where you can’t see it. Before anything else, try a different cable and a different power adapter that you know work with another device.

• Try another wall outlet. Power bars and outlets can fail too.
• Skip the laptop port for testing. Computer USB ports, older USB-A chargers and car chargers often supply much less power, so the phone may charge very slowly or just hold its level while you use it.
• Check the ends of the cable. Frayed jackets, bent connectors or discolouration are signs it’s time to replace it.
• Use certified gear. Very cheap, uncertified cables and adapters are a common cause of intermittent charging. For iPhone Lightning cables, look for MFi (Made for iPhone) certification.

If the phone charges normally with different accessories, you’ve found the problem. Our accessories page covers cables and chargers if you need a replacement.

2. Clean out the charging port (carefully)

Pockets and bags are full of lint, and it gets pressed into the charging port every time you plug in. Over months it packs into a solid layer at the back of the port, and the plug can no longer seat all the way. A telltale sign is a cable that feels loose or doesn’t click in firmly.

1. Turn the phone off.
2. Shine a flashlight into the port and look for lint, dust or sand.
3. If you see debris, gently loosen it with a wooden or plastic toothpick. Work lightly, and don’t scrape the pins or the small tongue in the centre of a USB-C port.
4. Never use metal objects such as pins, paper clips or SIM tools, and don’t blow into the port. Moisture from your breath doesn’t help.

If the debris is packed in hard, or you’re worried about damaging the connector, it’s safer to have the port cleaned professionally than to keep digging.

3. Check for heat or moisture warnings

Phones protect their batteries by pausing charging in certain conditions. That can look like a fault even though the phone is doing exactly what it was designed to do.

Too hot or too cold

If the phone gets hot, say while charging in direct sun, gaming while plugged in, or sitting on a wireless charger under a pillow, it may stop charging until it cools down. iPhones can show a message that charging is on hold. Unplug it, take off a thick case, let it come back to room temperature, then try again. A very cold phone, after a long winter walk for example, can also charge poorly until it warms up.

Liquid detected

Many iPhones and Samsung Galaxy phones detect moisture in the charging port and show a warning, and cable charging can stay blocked until the port is dry. After a Vancouver downpour this happens more often than you’d think. Unplug the cable, tap the phone gently with the port facing down, and let it air-dry. Wireless charging may still work in the meantime. Don’t use heat or compressed air to speed things along. Our guide on what to do when your phone gets wet walks through the rest.

4. Restart the phone, then update it

A software glitch can stop a phone from recognizing a charger, and a restart clears most of them.

• iPhone: for a force restart on recent models, press and release volume up, press and release volume down, then hold the side button until the Apple logo appears.
• Android: hold the power button (on many Samsung models, power and volume down together) and choose Restart. The exact buttons vary by model.

Once the phone is charging again, check for a system update in Settings. Updates sometimes include fixes for charging and battery behaviour.

On Android, if charging only misbehaves with certain apps running, restarting in safe mode can tell you whether a third-party app is involved. The steps differ between brands, so search your phone’s help pages for “safe mode”.

5. Look at your battery and charging settings

Some settings deliberately slow or stop charging to extend battery life, and they catch people off guard.

• iPhone: Optimized Battery Charging can hold the charge around 80% and finish later, based on your routine. Newer iPhones also offer a charge limit. Look under Settings > Battery.
• Samsung Galaxy: battery protection options can stop charging at a set level, such as 80 or 85%. Search Settings for “battery protection”.
• Other Android phones: many have adaptive or limited charging features. Search Settings for “adaptive charging” or just “charging”.

If your phone stops at the same percentage every single time, one of these settings is the likely reason, not a fault.

6. For wireless charging, check alignment and the case

Wireless charging is fussy about position. If the phone isn’t centred on the pad, it may charge very slowly or not at all.

• Remove thick cases, cases with metal plates, and wallet cases holding cards. Metal and cards can block or interfere with charging.
• Line the phone up with the centre of the pad, or use a magnetic charger if your phone supports one.
• Make sure the pad itself has enough power behind it. Many pads charge slowly when plugged into a weak adapter.

If wireless charging works but a cable doesn’t, the charging port is the more likely suspect, not the battery.

7. Give a completely dead phone some time

A fully drained battery may not show anything on screen right away. Plug the phone into a known-good charger and leave it alone for at least 30 minutes before you decide it’s dead. Then try a force restart while it’s still connected. If there’s still no sign of life after an hour on a charger you’ve confirmed works, a hardware fault is more likely.

8. Know the signs of a hardware problem

If you’ve worked through everything above, these symptoms point to a part that needs repair or replacement:

• It only charges when the cable is held at an angle, or when you press the plug in. That usually means a worn or damaged charging port.
• Charging connects and disconnects repeatedly with several different cables.
• The battery drains fast, shuts down at a random percentage, or the percentage jumps around. Those are common signs of a worn battery. See our list of signs your phone battery needs replacing.
• The phone was dropped or got wet and the charging trouble started soon afterwards.

Stop using and charging the phone if the screen is lifting, the back is bulging, or the phone gets unusually hot or smells odd. A swollen battery is a safety hazard. Keep it away from heat and have it looked at.
