Your iPhone won't charge — and these 7 fixes are ranked by how often they actually solve it
An iPhone that refuses to charge is almost always caused by one of seven things: a blocked port, a dead cable, a faulty adapter, a rogue app, a software glitch, a drained battery, or a hardware fault. Most of those are fixable in under five minutes without spending a single euro. This list is for expats and locals on the Costa Blanca who are sick of staring at a dead screen — and not interested in paying Mediamarkt prices to find out it was just pocket fluff.
We've ranked these causes from most common to least common, based on what actually walks through our door at Campoverde Repair. Start at number one, work your way down, and stop when your phone starts charging again. Simple.
The 7 Most Common Reasons Your iPhone Won't Charge — and What to Do
1. Blocked Charging Port — The Culprit 60% of the Time
Pocket lint, sand (hello, Costa Blanca beaches), and dust compact over time into a solid plug inside your Lightning or USB-C port. Your cable appears to connect, but the pins never make proper contact. Grab a wooden toothpick — not a metal pin — and gently scrape debris out. You'll be stunned how much rubbish comes out of there.
2. Dead or Damaged Charging Cable — The Second Most Common Killer
That cable that's been bent around a bedpost, run over by a chair, or chewed by a dog is not your friend. Apple's Lightning cables are famously fragile near the connector end — the insulation cracks, the internal wires break, and you lose charge delivery entirely. Swap in a known-good cable first before you do anything else. If borrowing a neighbour's cable fixes it immediately, you've found your problem.
3. Faulty or Underpowered Adapter — Not All Plugs Are Equal
That €4 no-brand charger from the Chinese bazaar on the N-332 might be killing your phone slowly — or simply not delivering enough wattage to charge it at all. iPhones need a minimum of 5W to charge; anything labelled "fast charge" should be at least 20W and Apple MFi-certified. Try a different, quality adapter and you may find that's all it takes. Cheap adapters also pose a real fire risk — just saying.
4. Software Glitch or iOS Bug — When the Phone Lies to You
Sometimes iOS just gets confused. The battery percentage freezes, the charging icon never appears, or the phone insists it's not charging even when it is. A force restart clears this instantly: on iPhone 8 and later, press and quickly release Volume Up, press and quickly release Volume Down, then press and hold the Side button until the Apple logo appears. Takes 10 seconds. Fixes more than you'd think.
5. Outdated iOS Version — A Known Bug Nobody Tells You About
Apple has shipped several iOS updates that specifically fixed charging-related bugs — including versions that caused iPhones to stop charging past a certain percentage or to drain faster than they could charge. Go to Settings → General → Software Update and install anything pending. Yes, updates can feel like a gamble, but running a known-buggy iOS version is worse.
6. Battery Too Drained to Show a Response — The "Dead Battery" Panic
If your battery hit absolute zero — we're talking left in a hot car for a week or forgotten for months — it can take up to 30 minutes of being plugged in before the screen shows any sign of life. Don't assume the phone is dead. Plug it in with a confirmed working cable and adapter, leave it alone for half an hour, and then check. Lithium batteries need a trickle charge to "wake up" when they're critically discharged.
7. Hardware Fault — The One You Can't Fix With a Toothpick
If you've worked through every step above and your iPhone still won't charge, the charging port itself may be physically damaged — bent pins, corrosion from moisture, or a broken solder joint on the board. This is especially common after a drop or water exposure (yes, even on "water-resistant" models — IP ratings are not a guarantee). At this point, you need a repair technician, not a YouTube video. The port replacement itself is straightforward if you know what you're doing; charging IC chip damage on the logic board is a different story entirely.
How We Ranked These — and How to Work Through Them
These aren't sorted by complexity or cost — they're sorted by frequency. In our experience at Campoverde Repair, a blocked port or knackered cable accounts for roughly two-thirds of all "iPhone not charging" complaints that come through the door. Hardware faults are real, but they're the minority. That's why we put the free fixes first.
Here's how to work through the list efficiently:
- Do the free stuff first: Clean the port, swap the cable, try a different adapter. This costs nothing and solves most cases.
- Force restart before you panic: It's non-destructive and takes 10 seconds. Do it earlier than you think you need to.
- Check iOS version before blaming hardware: A software bug masquerading as a hardware fault has wasted many people's repair money.
- If water was involved, stop charging immediately: Charging a wet phone can cause a short. Let it dry completely — 24-48 hours — before trying again.
- Don't let a "friend who's good with computers" poke around the port with a metal object: We've seen the results. Bent pins, scratched contacts, and one truly memorable fork incident.
If you've reached step 7 and nothing works, the next move is a professional diagnostic — not a new phone. A port replacement typically costs a fraction of what Apple or a chain store will quote you for a device swap, and you keep your data intact.
Key Takeaways
- A blocked port is the single most common reason an iPhone stops charging — clean it with a wooden toothpick before anything else.
- Always test with a known-good cable and adapter before assuming the phone itself is faulty.
- A force restart fixes charging display bugs on iPhone 8 and later in about 10 seconds, for free.
- A critically drained battery can take 30 minutes to show any screen activity — don't panic, just wait.
- If hardware is the issue, a port repair is almost always cheaper than a replacement device — get a professional diagnosis first.
The bottom line: For the overwhelming majority of iPhones that suddenly stop charging, the answer is a dirty port or a dead cable — both fixable in minutes, both completely free. If that doesn't solve it, bring it to us at Campoverde Repair before you start shopping for a new phone.
Frequently asked questions
Why is my iPhone plugged in but not charging?
The most common reason is a blocked charging port — lint and dust compact inside and prevent the cable from making proper contact. Clean the port gently with a wooden toothpick, then test with a different cable and adapter before assuming anything more serious is wrong.
How do I fix an iPhone that won't charge without taking it to a repair shop?
Work through these steps in order: clean the charging port, swap to a known-good cable, try a different power adapter, and perform a force restart (Volume Up, Volume Down, then hold Side button). These four steps alone resolve the majority of iPhone charging problems at zero cost.
Can a software update fix iPhone charging problems?
Yes — Apple has released multiple iOS updates specifically addressing charging bugs, including issues where phones stop charging past a certain percentage. Go to Settings → General → Software Update and install any pending updates before concluding you have a hardware fault.
How long does a dead iPhone take to turn on after being plugged in?
A critically discharged iPhone can take up to 30 minutes before showing any sign of life on the screen. Plug it into a working charger and leave it untouched for at least half an hour — the battery needs a trickle charge to recover from deep discharge before the phone can boot.
How much does it cost to replace an iPhone charging port?
A charging port replacement at an independent repair shop like Campoverde Repair is significantly cheaper than a device swap or Apple Store out-of-warranty replacement. Exact pricing depends on the iPhone model, but in most cases the repair preserves all your data and costs a fraction of a new device.
