You plug in your phone and nothing happens — no charging icon, no battery percentage climbing, maybe not even a flicker. Before you assume the worst and book a repair, work through this diagnosis checklist. Most "won't charge" problems come down to a cheap cable, a dirty port or a tired wall charger, all of which you can test and fix at home in minutes. This guide takes you from the easiest checks to the point where a real repair is needed. Start with the obvious (it usually is) Charging faults feel dramatic but are often trivial. Run these first, in order, because each rules out a common cause before you spend money. Try a different cable Cables are the single most common culprit. They flex thousands of times, fray internally near the connector, and a break in one tiny wire can stop charging while the cable still looks perfect. Swap in a known-good cable and try again. If it charges, you have your answer. This is exactly why keeping a spare quality cable around is worth it; our range of data and charging cables covers the common connector types so you always have a reliable backup on hand. Try a different charger and outlet The wall adaptor can fail too, and so can a power point. Australian mains runs at 230 to 240 volts, and a cheap or ageing adaptor can quietly degrade. Test with a different charger, ideally one you know works, and a different outlet or USB port. If the phone charges from a computer's USB port but not the wall plug, the adaptor is your problem. Browse tested wall units in our phone, tablet and laptop chargers collection if you need a replacement. Clean the charging port This is the fix people never think of and it solves a surprising number of cases. Phones live in pockets and bags, and lint compresses into the bottom of the charging port until the cable can no longer seat fully. If your cable feels loose, only charges at a certain angle, or clicks in without gripping, a blocked port is likely. How to clean it safely Power the phone off first. Use a wooden or plastic toothpick, never metal, to gently scrape the lint out. You will often be surprised how much compacted fluff comes out as a single plug. Finish with a short burst of compressed air to clear the rest. Avoid liquids and avoid poking hard at the small gold contacts, which can bend. Re-test with your cable. A firm, clicking connection that now charges means the port was simply blocked. Rule out software and heat Sometimes the hardware is fine and the phone has just frozen. A forced restart clears many temporary glitches — the button combination differs by model, so look up the sequence for your phone. Leave it on the charger for fifteen minutes first, because a fully flat battery can take several minutes to show any sign of life before the charging icon appears. Australian heat is a real factor Phones deliberately slow or pause charging when they get too hot to protect the battery. In an Australian summer, a phone left in a car, on a sunny windowsill or in direct sun can hit that limit easily. If your phone is warm and charging has stalled, move it somewhere cool, take the case off to help it shed heat, and try again once it has cooled down. This is normal protective behaviour, not a fault. Test whether it's the battery or the port If a good cable, a good charger, a clean port and a restart all fail, the fault is likely inside the phone — usually a worn-out battery or a damaged charging port assembly. Some clues help you tell them apart. A battery that drains extremely fast, shuts down at 20 or 30 percent, or has swollen enough to push the screen or back panel points to the battery. A port that only charges at a certain angle after cleaning, or that physically wobbles, points to the port assembly. Both are common DIY repairs on many models. A replacement battery or charging-port flex is inexpensive, and if you are comfortable opening the phone you can fit one yourself; our DIY phone repair tools and kits guide covers the heat, suction and pry tools these jobs need. A swollen battery, though, should be handled with care and kept away from heat, as it is a safety risk. Check the charging speed, not just whether it charges Sometimes the phone charges but painfully slowly, which points to a different set of causes. A cable that is not rated for fast charging, a low-wattage charger, or charging from a laptop USB port will all trickle power in slowly even when nothing is broken. So before assuming a hardware fault, confirm you are using a fast-charge-capable cable and an adequate wall charger rather than an old, underpowered adaptor. Background apps and a hot phone also throttle charging speed, so a slow charge on a warm summer day may simply be the phone protecting itself. Wireless charging as a clue If your phone supports wireless charging, it is a handy diagnostic tool. Place it on a wireless charger: if it charges wirelessly but not by cable, the battery is fine and the fault is almost certainly the charging port or its flex cable. If it will not charge either way, the battery or a deeper board fault is more likely. This simple test can save you opening the phone to find out. When to stop and seek help Call in a professional if the phone shows no life at all after trying multiple known-good chargers, if the battery is visibly swollen, if there is any sign of liquid damage, or if the charging port is physically broken or corroded. Board-level charging faults, where the charging circuitry on the logic board itself has failed, are beyond home tools and need a technician with a microscope and soldering equipment. There is no shame in reaching this point — you have already ruled out every cheap, common cause, which is exactly what a good repairer would have wanted you to do first. Remember too that under Australian Consumer Law, a phone or accessory that fails to charge within a reasonable time of purchase may entitle you to a remedy, so keep receipts and raise it with the retailer. Frequently Asked Questions Why does my phone only charge when I hold the cable at an angle? That symptom almost always means either a worn cable or a charging port clogged with lint. Try a fresh cable first, and if the problem persists, gently clean the port with a wooden toothpick, as compacted fluff stops the connector seating fully. Can a bad cable really stop charging completely? Yes. Cables fail internally where they flex near the connector, and a single broken wire can cut charging even though the cable looks fine on the outside. Swapping in a known-good cable is the fastest way to rule this out. Is it safe to clean my charging port myself? It is, provided you power the phone off and use a wooden or plastic toothpick rather than anything metal. Scrape gently, finish with a burst of compressed air, and avoid poking hard at the small contacts inside so you do not bend them. Why does my phone stop charging when it's hot? Phones pause or slow charging to protect the battery when they overheat, which happens easily in Australian summer heat or direct sun. Move the phone somewhere cool, remove the case to help it lose heat, and charging should resume once the temperature drops. How do I know if it's the battery or the charging port? A battery that drains fast, shuts down early or looks swollen points to the battery, while a port that wobbles or only charges at certain angles after cleaning points to the port assembly. Both are common repairs, but a swollen battery should be handled carefully and kept away from heat. Need a reliable cable or charger to test with, or to replace a failed one?
