Wireless Charging Not Working on iPhone? Every Fix Explained

You place your iPhone on the wireless charger, wait for the familiar chime — and nothing happens. No charging animation, no vibration, just silence. Wireless charging not working on your iPhone is frustrating precisely because there's no obvious point of failure. With wired charging you can inspect the cable, the port, the adapter. With wireless, it's invisible.

The good news is that wireless charging failures have a relatively short list of causes, and most of them are fixable at home. This guide walks through every possibility systematically — from the simplest fixes you can try in seconds to the hardware faults that need professional attention.

Quick check: Before diving in, confirm your iPhone supports wireless charging. Wireless charging was introduced with the iPhone 8 in 2017. If you have an iPhone 7 or earlier, wireless charging isn't a feature — you'll need wired charging exclusively. MagSafe was introduced with the iPhone 12 in 2020.

Understanding Qi vs MagSafe Charging

Before troubleshooting, it helps to understand the two wireless charging standards your iPhone may use:

Qi Wireless Charging

Qi (pronounced "chee") is the universal wireless charging standard. Every iPhone from the iPhone 8 onwards supports it. Qi chargers are the flat pads, stands, and mats from brands like Anker, Belkin, Samsung, and IKEA. They deliver up to 7.5W to iPhones (compared to 15W for Samsung and other Android devices — Apple limits third-party Qi to 7.5W for thermal management).

MagSafe Charging

MagSafe is Apple's proprietary system available on iPhone 12 and later. It uses a ring of magnets to align the charger precisely and delivers up to 15W — double the speed of standard Qi. If you're having MagSafe-specific issues, our dedicated MagSafe troubleshooting guide covers those in depth.

Qi2

Qi2 is the newer standard that incorporates MagSafe-style magnetic alignment into the universal Qi specification. iPhone 16 and later support Qi2 natively. Qi2 chargers deliver 15W to compatible iPhones without needing to be Apple-branded.

Quick Fixes to Try First (2 Minutes)

Start here. These solve the majority of wireless charging failures and take almost no time:

1. Remove Your Case

This is the number one cause of wireless charging failure that we see. Not all cases are created equal when it comes to wireless charging compatibility:

• Thick cases (over 3mm) can push the phone too far from the charging coil
• Metal cases or cases with metal plates (magnetic car mount plates, credit card holders) block the electromagnetic field entirely
• Wallet cases with cards — bank cards, Oyster cards, and similar RFID/NFC cards can interfere with wireless charging
• PopSocket or ring holder mounts — these create an air gap that prevents proper contact

Remove your case entirely and place the iPhone directly on the charger. If it charges, your case is the problem. Switch to a wireless-charging-compatible case (most modern silicone and thin TPU cases work fine).

2. Check Alignment

Wireless charging requires the phone's internal coil to align with the charger's coil. On standard Qi pads, the sweet spot is typically dead centre. If your phone is even slightly off-centre, charging may not initiate.

Try placing the phone in different positions on the pad. Many chargers have an LED indicator that changes colour or blinks when a device is detected versus actively charging — watch for this feedback as you adjust position.

3. Force Restart Your iPhone

A software glitch can prevent the wireless charging system from activating. Force restart your iPhone:

• 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
• This doesn't erase any data — it's just a hard reboot

4. Check for iOS Updates

Apple occasionally pushes updates that fix wireless charging bugs. Go to Settings > General > Software Update and install any pending updates. There have been notable instances — iOS 17.1 and 17.3 both addressed wireless charging reliability issues.

Case and Accessory Interference (The Most Common Cause)

It's worth spending extra time on this because it accounts for roughly 40% of the wireless charging complaints we see at celltech. Modern iPhone cases are generally designed to be wireless-charging friendly, but there are important exceptions:

Metal Interference

Any metal between the charger and the phone will block wireless charging. This includes:

• Aluminium or stainless steel case frames
• Metal plates for magnetic car mounts (the flat disc you stick to the back of the phone or inside a case)
• Metal credit card holders or card slots in wallet cases
• Decorative metal rings, badges, or brand plates on cases

Even small pieces of metal can disrupt the charging field enough to prevent charging from starting.

Thickness Issues

Qi charging operates over a very short range — typically under 8mm. Most phone cases add 1-3mm of thickness, which is fine. But rugged cases (OtterBox Defender, UAG Monarch, etc.) can add 4-5mm, which pushes the coils too far apart.

If you need a thick protective case, look for models that specifically advertise wireless charging compatibility. Alternatively, a MagSafe charger with strong magnets can pull through thicker cases more reliably than a flat Qi pad.

Screen Protectors

Standard tempered glass screen protectors do not affect wireless charging — the charging coils are on the back of the phone. However, privacy screen protectors with metallic privacy layers and some full-body wraps can occasionally cause issues if they extend to the back of the device.

Charger and Power Source Problems

If removing your case doesn't help, the issue may be with the charger itself:

Test With a Different Charger

If you only have one wireless charger, this is hard to verify at home. But if possible, try a friend's charger, a hotel charger, or a wireless charging spot in a coffee shop. If your phone charges on other pads but not yours, replace your charger.

Check the Power Adapter

Wireless chargers are only as good as the adapter powering them. Many cheap wireless chargers come with a cable but no adapter, and if you use an underpowered adapter (5V/1A), the charger may not deliver enough power to charge your phone.

• For Qi charging at 7.5W, you need at least a 5V/2A (10W) adapter
• For MagSafe at 15W, Apple recommends a 20W USB-C adapter minimum
• For Qi2 at 15W, a 20W+ adapter is required

Inspect the Charging Surface

Wireless charger surfaces can degrade over time. Look for cracks, peeling, or warping on the charging pad. Debris on the charger surface (crumbs, dust, spilt liquid residue) can also create enough of a gap to prevent charging.

Software and Settings to Check

Several iPhone settings can affect wireless charging behaviour:

Optimised Battery Charging

Apple's Optimised Battery Charging (Settings > Battery > Battery Health & Charging) learns your daily charging routine and may deliberately slow or pause charging at 80% to preserve battery longevity. This isn't a fault — it's a feature. But if your iPhone appears to "stop" wireless charging at 80%, this is likely why.

You can disable it temporarily to confirm, but we recommend leaving it enabled for long-term battery health.

Low Power Mode

Low Power Mode does not disable wireless charging, but it does reduce background activity that might make you think charging is slower. Wireless charging in Low Power Mode works normally.

Do Not Disturb / Focus Modes

Some Focus modes suppress the charging sound and vibration. Your phone may actually be charging even though you didn't hear the chime. Check the battery icon in the status bar — a lightning bolt or green fill indicates charging is active.

Reset All Settings

If software seems to be the culprit, try Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This preserves your data but resets all system settings to defaults. It's resolved wireless charging issues for many users when nothing else worked.

Hardware Faults That Prevent Wireless Charging

If you've exhausted all the software and accessory checks, the problem may be hardware-related:

Damaged Wireless Charging Coil

The wireless charging coil sits on the back of the phone beneath the rear glass. If the back glass is cracked, the coil itself may be damaged. Even hairline cracks in the rear glass can disrupt the coil's ability to receive power. A rear glass replacement is usually needed — and for iPhones, this is one of the more involved repairs.

Water or Liquid Damage

While modern iPhones are water-resistant (IP68), they're not waterproof. Liquid ingress — especially from saltwater, chlorinated water, or sugary drinks — can corrode the wireless charging coil connections. If your iPhone was recently exposed to liquid and wireless charging has since stopped, water damage is the likely cause.

Battery Health

A severely degraded battery can affect charging behaviour in unexpected ways. If your battery health is below 80%, the battery management system may limit or prevent wireless charging to protect the cell from stress. Check Settings > Battery > Battery Health & Charging.

Logic Board Fault

In rare cases, the wireless charging IC (integrated circuit) on the logic board can fail. This is the component that manages power reception from the coil and directs it to the battery. Logic board faults require microsoldering — a specialist repair that most high-street shops can't perform.

At celltech, we have full microsoldering capability for component-level logic board repairs. Our 120-day warranty covers all board-level work.

Which iPhones Support Which Wireless Standards?

Frequently Asked Questions

Can a cracked back glass stop wireless charging?

Yes. The wireless charging coil is attached to the underside of the rear glass. Significant cracks, especially around the centre of the back panel, can damage the coil or its connections. Minor cosmetic cracks near the edges are less likely to affect charging, but it's worth testing if wireless charging stops after dropping your phone.

Why does my iPhone get hot during wireless charging?

Some warmth is completely normal — wireless charging is inherently less efficient than wired charging, and the energy lost in the transfer becomes heat. However, if your phone gets uncomfortably hot (too warm to hold), stop charging immediately. Excessive heat can indicate a faulty charger, damaged coil, or battery issue. See our guide on iPhone not charging for more on heat-related charging problems.

Why does wireless charging stop at 80%?

This is almost always Apple's Optimised Battery Charging feature working as designed. It learns your routine and pauses charging at 80% until shortly before you typically unplug, to reduce time spent at full charge (which degrades lithium-ion batteries faster). You can disable it in Settings > Battery > Battery Health & Charging, but we recommend leaving it on.

Can I use my phone while it's wirelessly charging?

Yes, but it's not ideal. Picking up the phone may break alignment with the charging pad, and active use generates heat that compounds the heat from wireless charging. If you need to use your phone while charging, wired charging is more practical and efficient.

Is wireless charging slower than wired?

Yes, significantly. Standard Qi delivers 7.5W to iPhones, MagSafe delivers 15W, and Qi2 delivers 15W. By comparison, a 20W wired charger is faster than all wireless options, and a 30W wired charger is roughly twice as fast as MagSafe. For a deeper look, see our iPhone charging slowly guide.

Do I need an Apple-brand wireless charger?

No. Any Qi-certified charger will work with iPhone 8 and later. However, only Apple-certified MagSafe chargers deliver the full 15W — third-party Qi chargers are limited to 7.5W on iPhones (unless they're Qi2-certified, which delivers 15W to iPhone 16 and later). Quality third-party chargers from brands like Anker, Belkin, and Mophie are perfectly reliable.
