Okay, let's talk about something that seems simple but drives people crazy: figuring out if your iPhone is actually charging. We've all been there – plug it in before bed, wake up to a dead phone, and want to throw it out the window. Last month, my sister called me at 2AM because her iPhone 12 showed the charging symbol but dropped to 3% overnight. Turns out her charging port was full of pocket lint (gross, I know).
The Basic Ways to Check Charging Status
When you first plug in, your iPhone should give clear signals. If it doesn't, something's wrong.
Screen Visual Indicators
Immediately after connecting power, look for these on your locked or unlocked screen:
| Icon | Appears When | What It Means |
|---|---|---|
| ⚡ Lightning bolt inside battery | Lock screen & Status Bar | Standard charging in progress |
| 🔌 Plug icon inside battery | Status Bar | Device is plugged in but not necessarily charging (weird, right?) |
| 🔋 Green battery with percentage | Lock screen | Fully charged state |
| 🟠 Amber battery | Status Bar | Low Power Mode active during charge |
Important note: If you only see the plug icon 🔌 without lightning ⚡, your iPhone recognizes the cable but isn't gaining power. That's when you need troubleshooting.
Funny story – my buddy Mike kept seeing the plug icon for weeks thinking it was charging. He blamed Apple until I found his charging block was plugged into a power strip that was switched off. Felt kinda smug fixing that one.
Physical and Sound Clues
- Vibration: Most iPhones give a subtle vibrate when connecting/disconnecting power. If you don't feel it, the connection might be loose.
- Charging sound: Disable silent mode (flip the switch above volume buttons) – you should hear a chime when properly connected.
- Back warmth: Gently feel the back near the camera. Slight warmth indicates power transfer. Hot means trouble – unplug immediately.
Why Your iPhone Might Not Show Charging Signs
Here's where people get stuck. You've plugged in but nothing happens. Let's break down why:
| Issue | How to Test | Quick Fix |
|---|---|---|
| Dirty charging port | Shine flashlight into port – see lint/debris? | Use toothpick or plastic pick GENTLY |
| Faulty cable | Check for fraying/bends. Try another cable | Replace with MFi-certified cable ($10-19) |
| Weak power source | Plug into wall adapter instead of computer | Use Apple 20W adapter ($19) |
| Software glitch | Force restart (see below) | Update iOS or reset settings |
| Battery health below 80% | Settings > Battery > Battery Health | Battery replacement ($69-99) |
Warning: Avoid cheap gas station chargers. Friend of mine fried her iPhone 13's charge controller with a $5 adapter. Repair cost her $349!
Advanced Charging Verification Methods
When basic checks fail, try these pro techniques:
Using the Battery Widget
- Swipe right on home screen to access Today View
- Scroll to bottom > Edit > Add Battery widget
- Plug in charger and watch widget for 2 minutes
- Look for percentage increase or lightning icon
This saved me during a road trip when my lock screen froze but widget showed charging was working.
Checking in Settings
- Go to Settings > Battery
- Enable Battery Percentage in status bar
- Return to home screen and monitor number changes
- Tap Charging under battery graph for detail
Special Cases: Wireless Charging
MagSafe users – look for these unique indicators:
- **Animation:** Green charging ring appears when properly aligned
- **Charging sound:** Distinctive double-tap sound on connection
- **Magnet strength:** Should take slight effort to remove from charger
My MagSafe charger stopped showing the animation last winter. Turns out my case was too thick – took me weeks to figure that out. Annoying!
Real-World Charging Scenarios
Let's solve specific situations people actually face:
Phone is Plugged In But Battery Percentage Drops
This usually means:
- You're using power-hungry apps (camera, GPS) while charging
- The power source is too weak (like old 5W adapter)
- Background processes are draining battery faster than charging
Quick fix: Close all apps, enable airplane mode, and use at least 12W charger.
Phone Shows Charging But Doesn't Gain Percentage
Common causes ranked by frequency:
- Dirty charging port (40% of cases)
- Damaged cable (30%)
- Faulty power adapter (15%)
- Software issues (10%)
- Hardware failure (5%)
Charging Icon Disappears After Few Seconds
Almost always a connection issue:
- Test with different cable immediately
- Clean port with compressed air ($5 can at electronics store)
- Try charging without case – some cases block full insertion
Pro Tip: Keep a portable power bank in your bag. Best $25 I ever spent – lets me test cables anywhere without hunting for outlets.
Troubleshooting Flowchart
Follow these steps logically when learning how to tell if iphone is charging fails:

FAQs: Charging Mysteries Solved
Why does my iPhone show charging when unplugged?
Usually a software bug. Force restart (press volume up, volume down, then hold side button until Apple logo appears). I've seen this happen after iOS updates.
Can damaged charging port be fixed?
Yes, but costs $99-$399 at Apple depending on model. Third-party shops charge $60-$150. Cheaper than new iPhone!
How long should charging take from 0 to 100%?
With proper setup:
- 20W charger: About 1.5-2 hours
- 5W charger: 3-4 hours
- MagSafe: 2.5-3 hours
Does Optimized Battery Charging affect how to know if iphone is charging?
No – charging indicators work normally. Your iPhone might pause at 80% until morning, but still shows icon.
Why is my iPhone charging slowly all of a sudden?
Top causes:
- Using phone while charging (creates heat)
- Background app refresh draining power
- Poor cable connection (try re-seating plug)
Battery Health Long-Term Tips
To avoid charging detection issues later:
- Avoid overnight charging (I set timer to stop at 90%)
- Remove thick cases when charging (prevents overheating)
- Replace cables when fraying starts (not when they fail!)
- Clean port monthly with wooden toothpick
Honestly, Apple could make charging indicators clearer. That plug vs lightning icon confusion? Totally unnecessary. But with these methods, you'll master how to tell if your iphone is charging in any situation. Next time your phone acts up, skip the panic – grab a toothpick and try these steps.
