A Metal Plate for a Magnetic Car Phone Holder is a simple yet essential accessory that allows any smartphone—including older iPhones and Androids—to snap onto a magnetic mount.
While modern iPhones (12 and newer) have built-in magnets (MagSafe), they often still require these metal plates if your car mount is a traditional non-MagSafe magnet, or if you are using a thick case that weakens the internal magnetic pull.
🛠️ Types of Metal Plates
| Type | Best For | Description |
| Round Plate | Small/Standard Phones | Compact and discrete; ideal for minimalists. |
| Rectangular Plate | Large/Pro Max Phones | Provides a larger surface area to prevent the phone from "sliding" or rotating on bumpy roads. |
| MagSafe Ring | iPhone 12+ / Wireless Charging | A hollow ring shape that allows magnets to grab while letting wireless charging signals pass through the center. |
📍 Where to Stick the Plate
You have three main options for installation, depending on how you want your phone to look:
-
Directly on the Phone: Stick the plate to the back of the phone.
-
Tip: Use the "clear protective film" (usually included) first so the adhesive doesn't leave a permanent residue on your glass.
-
-
Inside the Case: Place the plate between your phone and the case.
-
Pros: Invisible.
-
Cons: If your case is very thick (like an Otterbox), the magnetic pull may be too weak to hold the phone securely.
-
-
Outside the Case: Stick the plate to the exterior of your case.
-
Pros: The strongest possible magnetic hold.
-
Cons: You will feel the metal plate when holding the phone.

⚡ Important: The Wireless Charging "Conflict"
Metal blocks wireless charging. If you use a standard solid metal plate, your phone will not charge on a wireless pad, and the plate may get dangerously hot.
-
The Fix: If you use wireless charging, place the plate at the very bottom of the phone, away from the center "coil" area.
-
The Better Fix: Use a MagSafe-compatible metal ring sticker instead of a solid plate.
💡 Pro-Tips for a Secure Mount
-
Clean the Surface: Use an alcohol wipe to clean the back of your phone/case before sticking. Any oil from your fingers will cause the plate to peel off within days.
-
The "Wait" Period: After sticking the plate, wait 1 hour before mounting it to the car magnet. This allows the 3M adhesive to fully cure.
-
Multiple Plates: If you have a very heavy phone, some users use two round plates (one at the top, one at the bottom) for maximum stability.
