Short answer
A thin case with built-in MagSafe barely gets in the way. Thick cases, metal cases and battery cases are the ones that slow charging down or stop it, and Apple itself says to take those off.
Why the case matters
Wireless charging works between two coils, one in the charger and one in the phone. The closer and better lined up they are, the better it works. A case sits right between them.

Case types Apple says to remove if charging is slow
Apple says that if your iPhone isn't charging, or charges slowly, and it has a thick case, a metal case or a battery case, you should try taking the case off (Apple).
A thin case adds very little distance, so the coils still meet. With built-in MagSafe, the magnets also pull the phone into the right spot every time.
Which cases cause problems
| Charging through it | Why | |
|---|---|---|
| Thin case with built-in MagSafe | Works well | Little distance, and the magnets line up the coils |
| Thin case without magnets | Usually works | The phone can slide off-centre on the charger |
| Thick or rugged case | Can be slow or stop | Too much distance between the coils |
| Metal case | Can be blocked | Metal gets in the way of charging |
| Battery case | Take it off | It has its own charging system |
| Card holder on the back | Take it off | Cards end up between the phone and charger |
Cards are worth a special mention. Apple says not to put credit cards, security badges, passports or key fobs between your iPhone and a MagSafe charger, because it might damage their magnetic strips or RFID chips (Apple). Take the card holder off before you charge.
How to charge at full speed
| What to do | |
|---|---|
| Centre the phone | Off-centre coils charge slower. MagSafe magnets do this for you. |
| Clear the back | Remove card holders, grips and anything else between phone and charger. |
| Keep it cool | Phones slow down charging when they get warm. Avoid charging in direct sun. |
| Use a strong adapter | A weak power adapter limits how fast any charger can go. |
Good to know. Some wireless charging stands have a small charging area. A case with MagSafe magnets keeps the phone in the right spot even when the stand is upright.

FAQ
Does a case slow down wireless charging?
A thin case with built-in MagSafe barely does. Thick, metal and battery cases can slow charging down or stop it.
Can I charge with a MagSafe card holder attached?
No. Take it off first. Apple says cards between the iPhone and a MagSafe charger may be damaged.
Why does my phone stop charging on the stand?
Usually it has slid off-centre, or it got warm and slowed down. A case with MagSafe magnets keeps it in place.
Does the RD Case V4 work with Qi2 chargers?
Yes. It has strong built-in MagSafe, so both MagSafe and Qi2 chargers line up and charge through the case.
