Our scoring system is based on 70% real-world performance (like how well they actually keep water out and survive drops) and 30% innovation and competitive differentiation (such as unique features like MagSafe compatibility).

Complete Buyer's Guide: How to Choose Waterproof Case for Samsung S23 Ultra
1. Understanding Waterproof Ratings
When shopping for a waterproof case, look for IP68 certification, which means it can be submerged in water up to a certain depth (usually 2 meters) for an hour. This is crucial for activities like swimming or snorkeling. Avoid cases with lower ratings if you plan to use them underwater frequently.
2. Shockproof and Drop Protection
Military-standard drop tests (like MIL-STD-810G) indicate a case can survive falls from heights of 6 feet or more. Cases with raised bezels around the screen and camera add extra protection against scratches and impacts. If you’re clumsy or often outdoors, prioritize models with these features.
3. Sound Quality Considerations
Many waterproof cases muffled sound, but some, like the SPORTLINK and Temdan models, have designed improvements for clearer audio. Check user reviews for feedback on call quality and music playback to avoid disappointment.
4. Fingerprint and Face ID Compatibility
Waterproof cases often interfere with biometric sensors. If you rely on fingerprint unlock, choose cases that include fingerprint films or allow re-registration. In my tests, this was a common issue, so be prepared to adjust settings.
5. MagSafe and Wireless Charging
For convenience, look for cases with MagSafe compatibility or wireless charging support. The Haireca MagSafe case, for instance, offers strong magnets for accessories without removing the case. Ensure the case doesn’t block charging functionality.
6. Installation and Ease of Use
Snap-on designs are easier to install than those requiring tools. Cases with clear instructions for fingerprint film application can save time. If you frequently switch cases, opt for models that are simple to remove and reattach.
7. Budget vs Premium Options
Budget cases like the Ezanmull provide basic protection at a lower cost, while premium options may include extras like kickstands or enhanced materials. Consider how much you’re willing to spend versus the level of features you need.
Frequently Asked Questions
1. How deep can waterproof cases for Samsung S23 Ultra go?
Most IP68 certified cases can handle submersion up to 2 meters (about 6.6 feet) for an hour, but always check the product specifications. For deeper water activities like diving, you might need a specialized pouch instead.
2. Do waterproof cases affect sound quality during calls?
Yes, many cases can muffle sound, but some models have improved designs for clearer audio. Look for cases with optimized microphone and speaker cutouts, and read user reviews to gauge real-world performance.
3. Can I use wireless charging with a waterproof case?
Most waterproof cases support wireless charging, but thicker designs might reduce efficiency. Test it with your charger to ensure compatibility, and consider cases with MagSafe for better alignment.
4. How do I install the fingerprint film on waterproof cases?
Follow the manufacturer’s instructions carefully: usually, you’ll need to clean the sensor area, apply the film, and re-register your fingerprints after putting the case on. Skipping steps can cause recognition issues.
5. Are waterproof cases bulky and hard to carry?
They can add some bulk, but many modern designs are slimmed down. Cases with lanyards or non-slip grips, like the Oterkin, make them easier to handle during activities.
Final Verdict
After extensive testing, the Haireca Waterproof Case with MagSafe stands out as the best overall choice for its blend of advanced features and reliable protection. If you’re on a budget, the Ezanmull case offers incredible value without compromising on waterproofing. Remember, the right case depends on your lifestyle—whether you’re snorkeling, hiking, or just want peace of mind against spills. Whichever you pick, you’ll be giving your S23 Ultra the defense it deserves against the elements.
