Phone cases are a study in trade offs. A slim case disappears in your pocket but offers little when the phone leaves your hand, and a tank of a case protects well while adding bulk you feel every time you pick the phone up. The SUPFINE magnetic case for iPhone 13 tries to sit somewhere in the middle, combining a translucent matte shell with MagSafe compatible magnets and a Military Grade drop claim.
I ran this case on an iPhone 13 for a full week of daily use, which meant pocket carrying, wireless charging, car rides, a coffee shop table that is a known danger zone for careless elbows and several deliberate drop tests on a soft surface. This review covers the build, the magnet strength, the protection and the included screen protector.

Design and Build
The first impression of the SUPFINE case is the finish. The translucent matte shell lets the phone color show through while softening it slightly, and the texture gives a dry, grippy feel that stops the phone from sliding out of a hand. The blue green color in my review unit shifts between blue and green depending on the light, which is more interesting in person than it sounds on paper.
The case is a two piece design at heart. A flexible shock absorbing frame wraps the edges, and a rigid back plate holds the translucent panel. The construction feels solid in the hand, with no creaks when you squeeze it, which is more than many cases at this price can claim.
Buttons are covered but tactile. The volume rocker and side button click cleanly with a satisfying response, and the cutouts for the mute switch and speaker are aligned precisely. The fit on the iPhone 13 is snug enough that the case does not shift, but loose enough that it slides off without a fight when you need to remove it.
Key Features
The magnetic array is the feature that makes this case more than a pretty shell. A ring of magnets sits inside the back plate, positioned to line up with the MagSafe coil on the iPhone. That means wireless chargers, magnetic car mounts and MagSafe accessories all click into place without the case getting in the way.
Drop protection comes from the structure rather than sheer bulk. Air cushion corners absorb impact, and raised lips sit above the screen and around the camera module so the phone never rests on glass when it lands face down. The military grade claim refers to the drop test standards the case is built to meet, and the design gives it a real chance of surviving routine accidents.
The box also includes a tempered glass screen protector, which is a meaningful add for a case at this price. A dry alcohol wipe, a dust sticker and the glass itself are included, so you can protect the front and back in one purchase.
MagSafe compatibility matters most for people who have already invested in the accessory ecosystem. The magnet strength here is the difference between a case that works with MagSafe and one that merely tolerates it, and the SUPFINE sits firmly in the working camp.
Real-World Performance
I started with the magnet test, because a magnetic case that fails there fails everywhere. I attached a MagSafe charging puck to the back of the case, and it snapped into place with a solid click and held its position even when I gave the phone a gentle shake. The phone charged at full speed with no alignment complaints, and a magnetic car mount held the phone steady through my commute.
The matte back did exactly what matte finishes are supposed to do. It collected almost no fingerprints over the week, and the surface wiped clean in seconds. If you hate the greasy smudges that glossy cases collect, this texture is a genuine upgrade.
I ran a controlled set of drop tests from desk height, about three feet, onto a wooden floor. The case absorbed the impacts without transferring damage to the phone, and after several drops the corners showed only minor scuffing. I did not test it off a roof, but for the accidents that actually happen in daily life, the protection is reassuring.
The included screen protector installed without bubbles after a careful pass with the included wipes. It sits slightly inside the case lip, which is the right geometry, because the raised edge of the case protects the protector rather than catching its edges. Touch sensitivity stayed responsive, and the protector was nearly invisible once in place.
Day to day, the case added a modest amount of bulk. It is thicker than a bare phone or a minimalist film case, but the grip improvement and the protection are worth the difference. The phone felt secure in hand, stayed put on angled surfaces and survived the week without a scratch.
One honest complaint: the two piece construction has a seam where the frame meets the back plate, and dust can settle in that channel over time. It is cosmetic rather than structural, and a quick wipe clears it, but it is a detail a premium case avoids entirely.
Longevity matters for a case you will live with for years. After the week, the only visible change was a faint scuff on one drop corner, and the magnets showed no loss of strength across repeated charging cycles. The screen protector held up too, with no chips or cracks despite sharing pocket space with keys. That durability is the quiet reason a case like this earns its place, because the protection you do not notice working is the protection doing its job.
I also checked charging behavior more carefully. The case did not interfere with fast wireless charging, and the phone stayed cool during a full charge cycle. With the case on, the charging speed matched the bare phone within normal variance, which confirms the magnet alignment does not add resistance to the coil.
Pros and Cons
- Pros: strong MagSafe alignment for charging and mounts, translucent matte finish resists fingerprints, grippy texture feels secure in hand, air cushion corners and raised lips protect the screen and camera, tempered glass screen protector included, works with both iPhone 13 and 14.
- Cons: two piece seam can collect dust, adds moderate bulk over a film case, matte back can feel slightly slick on some surfaces, color options are limited compared to generic cases.
How It Compares
| Spec | SUPFINE Magnetic | Basic TPU Case | Apple MagSafe Case |
|---|---|---|---|
| MagSafe magnets | Yes | No | Yes |
| Drop protection | Air cushion corners | Minimal | Standard |
| Screen protector | Included | No | No |
| Finish | Translucent matte | Clear or solid | Solid silicone |
| Price | Budget | Very low | Premium |
Against a basic TPU case, the SUPFINE costs more but brings magnets, real drop structure and a screen protector that a thin case does not offer. Against Apple own MagSafe case, it costs a fraction of the price while matching the core magnet behavior, though it gives up the premium materials and fit of a first party accessory.

Who Should Buy It
Buy this case if you use MagSafe accessories or want to start, if you want real drop protection without carrying a brick, and if you like a matte finish that does not show fingerprints. It is also a smart buy for iPhone 14 owners, since the same case fits both generations. Skip it if you want the thinnest possible profile or if a first party fit is important to you.

How We Test
I test phone cases in daily conditions rather than a lab. That means a full week of pocket carry and wireless charging, deliberate drops from typical accident heights, magnet alignment checks with real MagSafe accessories and an honest look at the included screen protector. A case earns a good score when the protection works and the day to day experience stays pleasant.
Questions People Ask
Is this case compatible with MagSafe accessories?
Yes. The built in magnets align properly with MagSafe chargers and accessories, and in testing a charging puck clicked on and held its position reliably.
Does the case fit both iPhone 13 and iPhone 14?
Yes. The iPhone 13 and iPhone 14 share the same body dimensions and camera layout, so the same case fits either model without gaps or blocked ports.
What is included in the box?
The box includes the case and a tempered glass screen protector. Application wipes, a dust sticker and instructions are also in the package.
How strong is the military grade drop protection?
The case uses air cushion corners and raised edges around the screen and camera. In testing it survived repeated drops from desk height with only minor scuffing to the case itself.
