| Pros | Cons |
|---|---|
| Excellent grip | Flexible |
| Lightweight and slim profile | Squishy, integrated buttons |
| Great screen access and low edge design | Below-average overall drop protection |
| Budget friendly | Uncomfortable pinky rest from port cutout |
| Comfortable matte texture |
The Ringke Onyx takes the familiar shape of the Ringke Fusion but trades clear plastic for a grippy matte finish that actually feels great in the hand. It’s lightweight, sleek, and surprisingly comfortable thanks to the textured edges and smooth top corners. But here’s the thing, just because it looks tough doesn’t mean it performs like it. Despite having oversized corners and solid MagSafe strength, its soft TPU build makes it one of the floppier cases we’ve tested. It’s a case that grips well but protects less, offering solid day-to-day handling but average impact resistance when things go sideways.
How We Test
30+ drops per case | 6+ metrics recorded per impact | 100% independently tested
Our goal is to find out what cases are actually best for your iPhone. We don’t base our reviews on any of the marketing a company wants you to believe. We’re reviewers, not influencers.
Our case testing procedure for the iPhone 17’s:
- Buy the case ourselves
- Measure all the physical dimensions of the case:
- Weight
- Size
- Back rigidity
- Corner/Back Thickness
- Corner compression
- Rank the handling and access of the iPhone in the case
- Perform magnetic strength tests using a force meter
- Perform audio tests (if needed using a DB meter)
- Perform 30 corner, face and camera lump drop tests. This data is collected from the iPhone’s accelerometer and gyroscope. We’ve built custom drop rigs to ensure every drop almost identical. To gauge the iPhone’s protective abilities, we measure:
- Average peak deceleration
- Average decay rate
- Average impulse
- Average max rotation
- Average angular displacement
- Average settling time
- After we collect all the data, we then run it through or scoring formula to figure out how well the case ranks.
We’ve got a few more ideas to implement for the next round of iPhone’s including more data collection during drops as well as high speed camera photos of the initial impacts.
Design
| Metric | Value | Average |
|---|---|---|
| Weight | 42 g | 45 g |
| Added Case Thickness | 42% | 51% |
| Added Overlook Bulk | 51% | 66% |
The Ringke Onyx might look like the non-clear version of the Fusion, but it’s not just a color swap. It’s a fairly thin TPU case that adds about 51% more bulk to your iPhone while staying light at only 42g which is one of the lightest cases in our 2025 test batch. The finish is what stands out most: a matte, slightly abrasive texture on the back paired with dotted grip strips along the edges. The top and bottom corners are smooth, giving it a nice contrast in hand. It’s minimalist, practical, and looks clean without screaming for attention.
Accessibility & Handling
| Metric | Value | Average |
|---|---|---|
| Grip | Abrasive matte back; dotted side texture with excellent hold | – |
| Buttons | Integrated; slightly squishy but better than Fusion version | – |
| MagSafe Strength | Pull 9.3 N / Push 11.8 N | 10.1 N |
Grip is where the Onyx shines. The mix of textures around the frame makes it easy to hold, even with sweaty hands, and honestly gives a false sense of security considering how flexible it is. The buttons are integrated and work better than Ringke’s clear version, but still feel a bit soft and squishy. The camera button isn’t covered, which helps responsiveness, and the larger port cutout is functional. However, the port cutout is not the most comfortable if you tend to rest your pinky there. On the bright side, screen access is excellent thanks to the low edge profile.
For MagSafe accessories, it takes 9.3 N to pull and 11.8 N to push, which is about 7% stronger than the test group average. So, no issues with slipping accessories here.
Protection
| Metric | Value | Average |
|---|---|---|
| Back Thickness | 2.2 mm | 2.4 mm |
| Corner Thickness | 2.2 mm | 2.9 mm |
| Air Pockets | Present | 10.1 N |
| Rigidity | 6.5 N | 29 N |
| Initial Impact | 11.858 G | 10.3 G |
| Rotation Rate | 167.44°/s | 300°/s |
| Time to Settle | 0.430 s | 0.53 s |
| Settling Rate | 0.080 s⁻¹ | 0.24 s⁻¹ |
| Total Force | 1.232 Ns | 1.5 Ns |
Despite its “tough” look, the Onyx doesn’t live up to its name in durability tests. The corners and back measure 2.2 mm thick and include 0.6 mm air pockets, but the TPU material is highly flexible. It only takes 6.5 N to bend it 8 mm, making it 77% floppier than the average case. That flexibility plays a big role in how it performs in drop tests.
In corner drops, it spiked at 11.9 G but spun less during descent, leading to a 40% better rotation rate. However, once it hit the ground, the phone kept wobbling longer, performing 65% worse in settling rate and 16% below average in total force absorption. Basically, it protects decently on first impact but struggles to control motion after the hit.
In face-first drops, those large corners help absorbed impact which is 30% better than average. Unfortunately, the settling rate was again poor (42% worse), bringing total protection back down to just average. Camera-lump drops were similar: 6% worse on initial impact, 20% worse decay rate, and 9% better total force. The pattern? Solid first impact, weak follow-through.
Compared to the Ringke Fusion, the Onyx is noticeably worse. Both share a TPU frame, but the Fusion’s polycarbonate back helped distribute energy better. The Onyx’s all-TPU build just doesn’t hold up as well under repeated drops.
Value
At its price point, the Ringke Onyx is a tempting pick for casual users. You’re getting a lightweight, well-textured, grippy case that looks clean and feels great to hold. But that comfort comes at the cost of real protection. It’s fine for everyday bumps, but not something we’d trust for repeated or serious drops.
If you’re someone who barely drops their phone or just needs something slim for a night out in tight jeans, it does the job. But if you want a true “tough case,” this isn’t it.
Verdict
Would we use it personally? Sure, but only for light days. The Ringke Onyx nails comfort and grip, but its soft structure and underwhelming protection hold it back. It’s a stylish budget case that looks tougher than it is. Great for minimalists but not for clumsy hands. In our ongoing 2025 drop tests, it ranks below average in total force protection, despite above-average grip and handling scores.
