What are the key features to look for in a waterproof case for the S23 Ultra

Key Features of a Waterproof Case

1. Water Resistance Rating:
- Look for cases with at least an IP68 rating, which indicates the case can withstand submersion in water beyond 1.5 meters for at least 30 minutes. Some cases can handle deeper water, such as up to 10 meters or more, which is ideal for diving or underwater photography[3][7].

2. Drop Protection:
- Ensure the case offers substantial drop protection, ideally rated for drops of at least 6 to 12 feet. This is crucial for safeguarding against accidental drops in various environments[1][4].

3. Built-in Screen Protector:
- A good waterproof case should include a built-in screen protector to prevent scratches and damage while maintaining touch sensitivity. This feature is particularly important for maintaining the functionality of the S23 Ultra's advanced display[1][3].

4. Camera Lens Protection:
- Look for cases that provide a raised camera lens cover or built-in lens protectors to avoid scratches and ensure high-quality photos, especially when taking pictures underwater[1][3].

5. Accessibility Features:
- The case should allow access to all ports and buttons without compromising its waterproof capabilities. Features like flexible rubber seals around ports and easy access to the S-Pen are beneficial[1][4].

6. Durability and Material Quality:
- Choose cases made from high-quality materials that are both rugged and lightweight, such as a combination of TPU (thermoplastic polyurethane) and hard plastic or metal. This ensures durability against impacts without adding excessive bulk[3][4].

7. Compatibility with Wireless Charging:
- Ensure that the case is compatible with wireless charging and supports features like reverse charging, which allows you to charge other devices using your phone[1][4].

8. User Reviews and Brand Reputation:
- Consider feedback from other users regarding real-world performance, especially concerning waterproof capabilities and durability over time. Brands known for reliable waterproof cases, such as Ghostek and Humixx, often have favorable reviews[5][6].

9. Warranty and Customer Support:
- A warranty can provide peace of mind regarding the product's longevity and manufacturer support in case of defects or issues[1][3].

By focusing on these features, you can select a waterproof case that not only protects your Samsung Galaxy S23 Ultra from water damage but also enhances its usability in various conditions.
