iPad Air 4 Not Charging

⚠️ First: USB-C Only

iPad Air 4 uses USB-C — not Lightning. If you have an older Lightning cable, it won't fit. This was the Air's first USB-C port, replacing Lightning that all previous Airs used.

🔍 Step 1: Diagnose the Problem

• No charging icon when plugged in: Cable or adapter failure, depleted battery, or dirty port
• "Not Charging" in status bar: Adapter wattage below screen-on draw — upgrade your charger
• Charges only when screen is off: Low-wattage adapter can't keep up with active display
• Slow charging (3-4% per hour): 5W phone charger — not adequate for iPad
• One cable works but another doesn't: Cable Power Delivery capability mismatch

⚡ Step 2: Charger Wattage

iPad Air 4 has a 28.65Wh battery (A14 Bionic). Low-wattage chargers cannot overcome screen-on power draw:

• 5W (old iPhone charger): Shows "Not Charging" with display active; trickle-charges with screen off
• 12W (older iPad charger): Barely keeps up; charges very slowly (4+ hours for full charge)
• 18W-20W USB-C PD: Proper charging speed — what Apple includes in the box
• 30W USB-C PD: Fast charge — best for quick top-ups

🔌 Step 3: USB-C Cable Quality

Not all USB-C cables support Power Delivery. A passive data cable may only allow 5-7.5W even with a 30W adapter:

1. Use the cable included with the iPad Air 4 — it supports full Power Delivery
2. Look for cables labeled USB-C PD or rated 30W+
3. Avoid ultra-thin USB-C cables — typically data-only with minimal current capacity
4. Inspect both ends for damage — USB-C cables fail internally at the connector bend

🧹 Step 4: Clean the USB-C Port

At 5+ years old, the USB-C port has had plenty of time to collect pocket lint:

1. Power off the iPad Air 4 completely
2. Use a wooden or plastic toothpick — never metal in USB-C
3. Shine a light in — look for debris at the back of the port
4. Gently scrape lint out toward the opening
5. Compressed air to clear remaining debris
6. Plug cable in — a clean port seats firmly with no wobble

⚙️ Step 5: Optimized Battery Charging

1. Settings → Battery → Battery Health → Optimized Battery Charging
2. If paused at 80%, this is working as designed — charging will complete based on your usage schedule
3. Disable temporarily if you need 100% right now

🔄 Step 6: Force Restart

iPad Air 4 (no Home button, Touch ID in power button):

1. Quickly press and release Volume Up
2. Quickly press and release Volume Down
3. Press and hold the Top button until Apple logo appears
4. Plug in charger after boot and check status bar for charging indicator

🔋 Battery Health

iPad Air 4 launched October 2020 — at 5+ years, battery wear is worth checking:

• Settings → Battery → Battery Health (iPadOS 17+)
• Below 80% capacity: battery replacement evaluation recommended
