Isolate charger, phone, and case
| Test | What it tells you |
|---|---|
| Same charger with another compatible device | Whether the pad and power source are likely working. |
| iPhone Duo without the case | Whether alignment or case thickness is interfering. |
| Different wall adapter | Whether the power source is limiting the pad. |
| Wired USB-C charging | Whether the issue is wireless-specific or broader. |
Safe order
- Use compatible power
Start with the accessory maker’s supported adapter and cable, connected to a wall outlet.
- Remove variables
Take off a case or wallet attachment for one controlled check; do not place cards or metal objects between charger and phone.
- Check temperature
Charging behavior can change when the device or room is hot. Move it to a cool, dry surface rather than adding refrigeration or direct airflow.
- Compare wired
If wired charging works, document the wireless setup. If both fail, use [[guides/iphone-duo-wont-charge|the USB-C charging guide]].
Capability is not a speed guarantee
Apple lists MagSafe up to 25 W and Qi2 up to 25 W under specified accessory and adapter conditions. A lower result can reflect the charger, adapter, case, temperature, battery state, or negotiated power—not necessarily a defective phone.
Confirmed
- Apple’s specifications list MagSafe and Qi2 charging and their maximum listed power conditions.
- Apple lists wired USB-C fast charging separately from wireless charging.
Provisional
- Third-party pad, case, and adapter behavior requires accessory-specific evidence.
FAQ
Why does MagSafe work without my case but not with it?
The case may change alignment, thickness, or magnetic coupling. Use a compatible case or charger combination and check the accessory maker’s specifications.
Does Qi2 charge at 25 W for every pad?
No. Apple’s specification gives a maximum condition; the pad, adapter, phone temperature, and negotiated power determine the actual result.
