You place your phone on the wireless charging pad and nothing happens — no charging animation, no sound, no indicator light, or the charging starts and immediately stops. Wireless charging failures are common and almost always caused by alignment, a case, a setting, or a charger issue rather than a broken phone. This guide walks through every cause and fix.
Check phone placement and alignment
Wireless charging requires the charging coil in your phone to align with the coil in the charger. Even a small misalignment can prevent charging:
The charging coil is in the center-back of most phones, but the exact position varies by model. Place the phone in the center of the charging pad and adjust it slightly in all directions until the charging indicator appears
On flat pads, the coil is usually in the center. On angled stands, the coil is at a specific height — make sure your phone is resting in the designed position, not slid up or down
MagSafe chargers (iPhone 12 and later) and Qi2 chargers use magnets to snap the phone into the correct position automatically. If you are using a MagSafe charger and it does not snap firmly, there may be a case or debris interfering with the magnets
Try charging with the phone in portrait orientation if you normally use landscape, or vice versa. Some phone and charger combinations align better in one orientation
Remove the phone case
Phone cases are the most common cause of wireless charging failure:
Thick cases: Wireless charging works through materials up to about 3 to 5 millimeters thick. Rugged cases, battery cases, and cases with built-in card holders or kickstands are often too thick for the charging signal to pass through
Metal cases or metal plates: Any metal between the phone and charger blocks wireless charging completely. This includes metal cases, metal ring holders, magnetic car mount plates stuck to the back of the phone, and cases with metal kickstands that fold flat against the back
Card holders: Credit cards and ID cards with magnetic strips or RFID chips can interfere with wireless charging. If your case has a card slot, remove the cards and try charging
Remove the case entirely and place the phone directly on the charger as a test. If it charges without the case, the case is the problem — switch to a thinner case or one specifically rated as wireless-charging compatible
Check the charger and power source
Power adapter: Wireless chargers require a power adapter that provides enough wattage. Many wireless chargers come without an adapter and the old 5W adapter from a previous phone may not provide enough power. Check the charger specifications — most require at least a 10W to 20W adapter. If the indicator light on the charger is not turning on at all, the power adapter or cable may be the issue
USB cable: Try a different USB cable between the power adapter and the wireless charger. Cables degrade over time and a failing cable may provide intermittent power
Power outlet: Plug the charger into a different outlet. A loose or partially working outlet can cause intermittent charging
Charger surface: Make sure the charging pad surface is clean and free of debris. Dust, coins, or small objects between the phone and charger can prevent proper contact or cause the charger to detect a foreign object and stop charging as a safety measure
Foreign Object Detection
Most wireless chargers have a safety feature that stops charging if they detect a metal object on the pad. This prevents the charger from heating metal objects (which could burn you or damage the phone):
Remove everything from the charging pad — no coins, keys, paper clips, or other items. Even a small piece of metal can trigger foreign object detection and stop charging
If the charger blinks orange or red (the exact behavior varies by brand), it is usually indicating a foreign object detection or an error. Clear the pad and try again
Some chargers are overly sensitive and may trigger foreign object detection from metallic phone accessories, certain case materials, or even metallic paint on the phone itself
Restart the phone
A simple restart clears any software glitches that may be preventing the phone from communicating with the charger. Wireless charging involves a handshake between the phone and charger — the phone tells the charger what power level to deliver. If this handshake fails, charging does not start
After restarting, place the phone on the charger again. This resolves intermittent wireless charging failures that come and go
Check phone settings
iPhone: There is no setting to disable wireless charging on iPhone directly. However, if Optimized Battery Charging is enabled (Settings, Battery, Battery Health and Charging), the phone may intentionally stop charging at 80 percent to reduce battery wear. This is normal behavior, not a failure
Samsung: Go to Settings, Battery and Device Care, Battery, More Battery Settings. Make sure Wireless Charging is toggled on. Also check Fast Wireless Charging — if it is off, the phone charges wirelessly but at a slower rate which may seem like it is not charging
Other Android phones: Check Settings, Battery for any wireless charging toggle. Some phones have a setting that limits wireless charging speed or disables it entirely
Battery Saver or Low Power Mode: Some phones disable or limit wireless charging when battery saver mode is active. Turn off battery saver and try again
Check for software updates
Wireless charging compatibility issues between specific phone software versions and charger firmware are occasionally reported. Update your phone to the latest OS version: Settings, General, Software Update (iPhone) or Settings, System, System Update (Android)
If wireless charging stopped working immediately after a software update, search online for the specific issue (for example, iOS 18 wireless charging not working) — known bugs are usually documented and fixed in the next update
Temperature issues
Wireless charging generates more heat than wired charging. Phones have built-in thermal protection that slows or stops charging when the temperature gets too high
If the phone or charger feels very warm and charging stops, let both cool down. Remove the phone case (cases trap heat), move the charger out of direct sunlight, and wait 10 to 15 minutes before trying again
Charging in a hot car, in direct sunlight, or on a surface that retains heat (soft fabric, pillow) causes temperature shutoffs. Use wireless chargers on hard, ventilated surfaces
If the phone shows a temperature warning when you place it on the wireless charger, the phone is already too warm to start charging. Let it cool first
Charger compatibility
Qi standard: Most modern phones use the Qi wireless charging standard. If your charger is Qi-compatible and your phone supports Qi, they should work together regardless of brand. Check both the charger and phone specifications for Qi support
Qi2 and MagSafe: Qi2 is the latest standard, based on Apple MagSafe. Qi2 chargers work with all Qi phones but deliver maximum speed only with Qi2-compatible phones (iPhone 12 and later with MagSafe, and newer Android phones with Qi2 support). Older Qi phones charge on Qi2 pads at standard Qi speeds
Proprietary chargers: Some Samsung and OnePlus fast wireless charging features require specific chargers from the same brand to achieve maximum speed. A generic Qi charger will still charge these phones, just not at the fastest rate
Very old chargers: Qi chargers from before 2018 may not support newer power profiles. If you have a very old wireless charger, it may only deliver 5W which charges extremely slowly — slow enough that using the phone while charging drains faster than it charges, making it seem like it is not working
Test with a different charger or phone
If you have access to another wireless charger, try your phone on it. If it charges on a different charger, your original charger is the problem
If you have another phone that supports wireless charging, try it on your charger. If the other phone charges, your phone may have a hardware issue
This cross-testing isolates whether the problem is the phone or the charger — an important distinction before spending money on a repair or replacement
When wireless charging needs repair
If wired charging works fine but wireless charging does not work on any charger, and you have ruled out cases, alignment, and settings, the wireless charging coil or its connection inside the phone may be damaged. Drops can disconnect the coil ribbon cable, and water exposure can corrode the coil contacts. Marion Phone Repair can test the wireless charging coil, check the internal connections, and determine whether the coil needs reseating or replacement.
