If you are looking for accessories or designing hardware for Apple’s magnetic system, you might have a question. Which MagSafe chargers work well with phones? In short, iPhone 12 and newer have native MagSafe; many Android models can join the party using Qi2 or MagSafe-style magnet rings/cases. CORT MAGNET explains what “MagSafe compatible” means. It also shows how to check your device. Plus, learn how to upgrade older phones with magnet rings and shields.
TL;DR: iPhone 12+ works out of the box. Android can work like MagSafe using Qi2 or a magnet ring case. However, charging speed and reliability depend on alignment, coil position, and shielding quality

What does “MagSafe compatible” mean?
MagSafe is Apple’s magnetic alignment system layered on top of Qi wireless charging. True compatibility requires:
- Qi or Qi2 wireless charging in the phone.
- A precise magnet array around the charging coil (ring + alignment/anti-rotation magnet).
- Magnetic shielding to prevent interference with antennas, sensors, and compasses.
- Tuned power/thermal management so the device negotiates stable wattage without overheating.
Native vs Accessory-Enabled Compatibility
| Feature | Native (iPhone 12+) | Accessory-Enabled (Android/older iPhone) |
|---|---|---|
| Magnet Array | Built into phone | Added via ring sticker or MagSafe-case |
| Alignment Accuracy | Very high, factory-tuned | Varies by brand/build |
| Typical Charging Speed | Up to 15W on Apple MagSafe | 7.5–10W typical; Qi2 can reach 15W where supported |
| Accessory Fit | Full ecosystem (mounts, wallets) | Works if magnet pattern matches; some limits |
| Shielding | Built-in | Depends on case/ring design |
For accessory designers and OEMs, CORT MAGNET manufactures NdFeB (neodymium) magnet rings, keeper plates, and custom arrays to hit Apple-like alignment tolerances while minimizing stray fields. Explore our capabilities:
How do I check if my iPhone is MagSafe compatible?
All iPhones from the iPhone 12 series and newer (12, 13, 14, 15,16,17) have a magnet ring. They also have a charging coil for MagSafe. You can verify by:
- Opening Settings ▸ About to confirm your model, then checking Apple’s tech specs page for your device.
- Looking for the MagSafe badge on Apple-made cases and chargers.

What’s the difference between MagSafe and normal wireless charging?
Normal Qi relies on your eyeballing the placement; any misalignment slows or stops charging. MagSafe uses a magnet ring to auto-align coil-to-coil, improving:
- Efficiency (less heat for the same wattage),
- Consistency (fewer drop-outs during use),
- Convenience (snap-on mounts, stands, wallets).
Qi2 is the new Qi standard. It adds a Magnetic Power Profile like Apple’s. This feature allows Android phones and accessories to align easily, just like iPhones
Are Android phones MagSafe compatible?
Out of the box: most Android phones do not include Apple’s MagSafe ring, but many support Qi. Three ways Android can work with MagSafe-style chargers:
- Qi2-certified phones/accessories (native magnets + alignment; up to 15W where supported).
- MagSafe-compatible cases with a built-in ring that matches the iPhone magnet pattern.
- Stick-on magnet rings applied to the phone or case (budget-friendly, accuracy varies).Pro tip from CORT: ring positioning matters. Even a 1–2 mm offset between the ring center and coil center can cut effective power. Use alignment jigs and high-temp adhesives.
Need rings or arrays? Please discuss N48–N52 NdFeB rings. These rings can have Ni-Cu-Ni or epoxy coatings. You can also add mu-metal or steel keepers to shape the magnetic field
How to make my older phone “MagSafe-ready”
You can retrofit in minutes:
- MagSafe Ring Sticker: ultra-thin NdFeB ring + alignment bar.
- MagSafe-Compatible Case: pre-installed ring with better centering and shielding.
- Qi Receiver Patch (for phones lacking Qi): a thin coil + USB-C/Lightning tail, plus a magnet ring (adds bulk; speeds vary).
Retrofit Options Compared
| Method | Install Effort | Look/Feel | Alignment Quality | Notes |
|---|---|---|---|---|
| Ring Sticker | 5 minutes | Thinnest | Good if centered | Use jig; clean surface; high-temp adhesive |
| MagSafe Case | Snap on | Slightly thicker | Very good | Often adds shielding for compass stability |
| Qi Receiver + Ring | 10–15 minutes | Thickest | Fair | For phones without Qi; slower speeds |
CORT MAGNET supplies custom ring kits (diameters, magnet grades, plating, and adhesive specs) for case brands and enterprise fleets. Start a spec with our team:
What materials and specs make a good ring?
- Magnet grade: N48–N52 NdFeB for strong hold in a thin form factor.
- Plating: Ni-Cu-Ni (durable), epoxy (better corrosion resistance), Au (special electronics use).
- Keeper/Shield: thin steel or mu-metal plate to reduce stray fields and protect compasses/NFC.
- Adhesive: high-temperature acrylic (≥90 °C) with surface primer for cases with coatings.
- Dimensional control: OD/ID runout ≤0.1 mm; concentricity to coil center is critical.
Will magnets damage my phone?
- Quality magnets, correctly placed and properly shielded, do not damage phones. Risks arise from:
- Over-strong arrays near sensors (compass drift),
- Poor shielding near NFC or UWB antennas,
- Cheap adhesives that creep under heat and shift alignment.
CORT MAGNET validates ring pull force, field mapping, and thermal cycling to prevent these issues. Learn about our process on the About Us page.
Charging speed realities (and expectations)
- iPhone 12+ with Apple-certified MagSafe: up to 15W under ideal conditions.
- Android + MagSafe-style case: often 7.5–10W on standard Qi; Qi2 combos can hit 15W where both sides support it.
- Heat & throttling: any misalignment or thick case inserts reduce power; alignment magnets help mitigate this by centering the coils.
How to verify your setup is actually aligned
- Feel the snap: a clean, centered “lock” with minimal sliding.
- Thermal check: back of phone warm, not hot; hot spots signal misalignment.
- Wattage apps/meters: observe stable power (varies by OS/accessory).
- Compass test: open a compass app; if the heading drifts while attached, you need better shielding or a different case.
Buyer’s checklist for MagSafe accessories
- Ring geometry: OD/ID matches iPhone pattern; include anti-rotation bar.
- Magnet material: NdFeB N48–N52, thickness matched to case wall.
- Keeper plate: present and sized to reduce stray fields while maintaining pull.
- Adhesive: high-temp tape with primer; peel strength spec’d.
- Coil clearance: do not obstruct NFC/antenna paths.
- Certifications: look for Qi/Qi2 marks; Apple MFi where applicable.

FAQ: “MagSafe charger compatible phones”
Q1: Which phones are natively compatible?
iPhone 17 and newer. These include the built-in magnet array and tuned charging control.
Q2: Can Android get the same snap and charge?
Yes—via Qi2 hardware or a MagSafe-compatible case/ring. Charging speed and reliability depend on alignment and coil design.
Q3: Do magnets affect credit cards or key fobs?
Modern wallets use shielding, but avoid direct contact between bare magnets and magnetic stripes. Use certified MagSafe wallets.
Q4: What if my phone heats up?
Heat usually means misalignment or thick materials between coils. Re-center, switch to a thinner case, or choose a Qi2 charger/phone pair.
Q5: Where can I buy quality rings or arrays?
For OEMs, integrators, and brands, CORT MAGNET produces precision neodymium rings and assemblies with tight tolerances and coatings suited to consumer electronics. Start here: Neodymium Magnets • Customized Service • Contact
