Why the OnePlus 13 Deserves Great Protection
The OnePlus 13 launched in January 2025 with Snapdragon 8 Elite, a 6.82-inch LTPO 2K display, Hasselblad-tuned triple camera with 50 MP periscope telephoto, 6,000 mAh battery, and 100W wired charging. It is one of the most capable Android flagships of its generation at a significantly lower price than Samsung Galaxy S Ultra or iPhone 17 Pro Max. The OnePlus 13 builds on OnePlus's OxygenOS experience with lean software and fast Android updates.
OnePlus flagship owners often have excellent taste in hardware but less choice in quality cases. The Gorilla Cases OnePlus 13 slim case fills the gap — precision cutouts for the Hasselblad camera module, alert slider, and USB-C port, all within a MIL-STD-810G certified package. This is the case the OnePlus 13 deserves from a brand that takes case engineering as seriously as OnePlus takes performance engineering.
Alert Slider: The OnePlus Signature Feature
The alert slider on the OnePlus 13 right edge is one of the most distinctive hardware features in Android — a three-position physical switch for silent, do-not-disturb, and ring modes. Designing a case cutout for the alert slider requires accounting for the full travel of the switch in all three positions while maintaining a case wall that does not flex during slider operation. The Gorilla Cases OnePlus 13 slim case cutout is 0.8 mm wider than the alert slider on all sides and includes a recessed channel for finger purchase — users can operate the alert slider without removing the case or repositioning their grip.
Hasselblad Camera Module Engineering
The OnePlus 13 Hasselblad camera module protrudes 4.2 mm from the device back. The circular camera array contains the 50 MP main, 50 MP ultrawide, and 50 MP periscope telephoto. The Gorilla Cases slim case raises the camera ring cutout 1.5 mm above the case back surface — protecting all three lenses from direct surface contact during horizontal placement. The cutout circle matches the Hasselblad module outer diameter with 0.5 mm clearance to account for manufacturing tolerance without creating an oversized gap that would accumulate debris.
100W Fast Charging and Wireless Charging Access
The OnePlus 13 supports 100W wired fast charging via USB-C — enough to charge from zero to 100 percent in approximately 36 minutes. The Gorilla Cases slim case USB-C cutout is machined to accept USB-C cables including aftermarket 100W charging cables with up to 11 mm plug housing diameter. No cable removal is required during the charge cycle. The OnePlus 13 also supports 50W wireless charging — the Gorilla Cases slim case polycarbonate back does not attenuate the wireless charging coil and maintains full 50W wireless charging speed through the case.
Customer Story: The Android Enthusiast
Marcus Rodriguez, 29, a software developer in Austin, Texas, chose the OnePlus 13 over a Galaxy S25 Ultra because of OxygenOS's clean interface and the 100W charging speed that fits his always-on development schedule. He needed a slim case that did not add weight — he carries the phone in a single back pocket with his wallet and keys. The Gorilla Cases OnePlus 13 slim case at 22 grams added less than his wallet card to the total carry weight. He has dropped the phone once from a standing desk at 1.1 m onto hard concrete floor — corner impact — with zero damage to the phone or case. Use code 10OFF at gorillacasestore.com.

Protection Tips from Gorilla Gearheads
The OnePlus 13 alert slider uses a physical detent mechanism — do not force the slider through the case cutout using tools. If the slider feels stiff through the case, remove the case and inspect the cutout for debris. Pocket lint is the most common cause of stiff alert slider operation through case cutouts — a compressed air can or a dry toothbrush clears the cutout in seconds. Check the case seating at the alert slider position every 30 days — this is a high-mechanical-stress area of the case due to repeated slider actuation.
Available Colors
The Gorilla Cases OnePlus 13 slim case is available in matte black, frost clear, and slate gray.
