Your battery is at 3%. You plug it in. Nothing happens.
When your iPhone is not charging, it can feel urgent, especially if you’re about to head out or expecting an important call. Before assuming your battery is dead or your phone is broken, know this: most charging issues are caused by simple, fixable problems.
If you're thinking, “My iPhone won’t charge, and I don’t know what’s wrong,” this guide will walk you through the real reasons it happens, and what each one actually means.

iPhone Is Not Charging Even When Plugged In? Start With the Basics
If your iPhone is not charging when plugged in, always check accessories first. They fail more often than the phone itself.
1. Test the Cable First (Most Common Cause)
Charging cables bend, twist, and get pulled daily. Over time, the wires inside weaken, even if the outside looks fine.
Why this matters: A damaged cable may show the charging symbol but deliver inconsistent power. That’s why the percentage sometimes doesn’t increase.
What to do:
- Try a different Apple-certified cable
- Avoid very cheap or unverified brands
- Check for fraying near the connector
This quick test often solves the issue in minutes.
2. Check the Power Adapter and Outlet
Not all outlets deliver steady power. Some USB ports (like those built into lamps or laptops) don’t provide enough current.
Why this matters: Your phone might appear to charge but actually drain slowly because it’s receiving too little power.
What to do:
- Plug directly into a wall outlet
- Try a different adapter
- Avoid USB hubs or extension splitters
If switching outlets fixes it, the phone was never the problem.
3. Check Battery Health Before Assuming It’s Dead
To check battery health, go to: Settings → Battery → Battery Health
If maximum capacity is under 80%, your battery has significantly aged.
Signs of battery wear:
- Rapid drain
- Sudden shutdowns
- Percentage jumps
Why this matters: A degraded battery can struggle to accept or hold charge efficiently. In many cases, replacing the battery restores normal performance without needing a new phone.
Quick Troubleshooting Order (Start Here)
If your iPhone is not charging, follow this order:
- Test a different cable
- Test a different adapter
- Try another outlet
- Clean the charging port
- Force restart
- Check battery health
- Disable optimized charging temporarily
This step-by-step approach prevents unnecessary repair costs.
iPhone is Not Charging? Here are Some Common Scenarios
If the basic troubleshooting steps above don’t work, check the scenarios below that best fit your situation.
1. Port Might Be Blocked
If the cable feels loose or only charges at certain angles, you may be dealing with an iphone charging port not working properly.
Pocket lint is one of the biggest hidden causes of charging failure.
Why this matters: Even a thin layer of compressed dust can stop the cable from clicking in fully, preventing a stable connection.
What to do:
- Use a wooden toothpick (never metal)
- Gently remove debris
- Do not pour liquid inside
If cleaning restores charging, the issue wasn’t internal damage, just buildup.
2. iPhone Says It’s Charging But the Battery Isn’t Increasing
This is frustrating: you see the lightning icon, but the percentage stays the same or even drops.
When this happens and you think, “my iPhone won’t charge properly,” it’s often software-related.
-
Force Restart (Fixes Many Glitches): After updates, charging bugs can occur. A force restart resets the power system without deleting data.
- For iPhone 8 or later:
-
-
- Press and release Volume Up
- Press and release Volume Down
- Hold the Side button until the Apple logo appears
-
Why this matters: If a restart fixes it, the issue was software, not battery damage. That’s an important distinction before considering repairs.
3. Why is My iPhone Won’t Charge Past 80%? It May Be Intentional
If your iPhone is not charging beyond 80%, it may actually be protecting your battery.
Apple includes features that pause charging to reduce long-term battery wear.
- Optimized Battery Charging: Your phone learns your routine and delays charging past 80% until you’re likely to unplug it. To check, go to Settings → Battery → Battery Health & Charging
Why this matters: This is not a malfunction. It extends battery lifespan. You can temporarily disable it to test, but it’s usually better to leave it on.
4. iPhone Not Charging Past 50% or Draining While Plugged In
If your phone stays at 50% overnight or loses charge while plugged in, something is interfering with stable power delivery.
Likely causes:
- Weak charger output
- Software glitch
- Battery degradation
- Overheating
Why this matters: If the charger is underpowered, your phone may use energy faster than it receives it, especially during background updates or app activity.
Try:
- A 20W or higher adapter
- Force restart
- Checking battery health
5. Overheating Can Pause Charging
If your phone feels warm, charging may slow or stop automatically.
Why this matters: This is a safety feature. Charging a hot battery can shorten its lifespan.
Common triggers:
- Gaming while charging
- Charging in direct sunlight
- Thick phone cases trapping heat
Move it to a cooler area and remove the case temporarily.
6. My iPhone Won’t Charge After an Update
Some users notice charging issues immediately after installing a new iOS version.
Why this happens:
- Temporary software instability
- Power management bugs
- Background reindexing after update
Try:
- Force restart
- Install latest patch update
- Reset all settings (this does not delete personal data)
If charging works after restarting but fails later, it’s likely a software bug rather than hardware damage.
When It Might Be Hardware Damage
If your iPhone is not charging when plugged in even after testing cables, cleaning the port, and restarting, internal damage becomes more likely.
Warning signs:
- No charging icon at all
- Visible port damage
- Phone overheats abnormally
- Wireless charging also fails
Why this matters: Continuing to force the cable into a damaged port can worsen internal connectors. At this point, professional inspection is the safer step.
Frequently Asked Questions
Why does my iPhone say it’s charging but not plugged in?
When a charging symbol appears without being connected, it may be caused by a temporary system error or a sensor misreading. Moisture detection components inside the port can sometimes trigger falsely. Restarting the device often clears this behavior. If the issue repeats frequently, a software update or inspection may be needed.
What are signs of a failing iPhone battery?
A weakening battery may drain much faster than it used to, even with light use. The phone could shut down unexpectedly or heat up more than usual. You might also notice inconsistent percentage readings. Checking the Battery Health section in settings provides a clearer indication of overall battery condition.
Is it worth replacing an iPhone battery?
If the device still performs well otherwise, replacing the battery can significantly improve daily use. A new battery restores longer usage time and more stable charging behavior. It is often more affordable than purchasing a new phone. Checking warranty coverage first can also reduce replacement costs.
Final Thoughts: Keep Your iPhone Charging Smoothly
Most iPhone charging issues are simple to fix once you know the causes. By checking accessories, keeping the port clean, and following smart charging habits, you can avoid frustration and protect your battery.
Quick Takeaways:
- Check cables and adapters – damaged or non-certified accessories often cause charging issues.
- Clean the charging port – lint or debris can block a proper connection.
- Restart your iPhone – resolves most software-related charging glitches.
- Watch battery health – replace when capacity drops below 80% for reliable performance.
- Avoid heat – keep your iPhone cool while charging to protect battery lifespan.
- Use optimized charging features – Apple’s safeguards help extend long-term battery life.
Follow these simple steps, and your iPhone should charge reliably, lasting longer between replacements.
