How does the IPX8 rating of the Galaxy Z Fold 5 enhance its water resistance compared to its predecessor

Understanding IPX8 Rating

IPX8 means that the device has been tested for water resistance but not for dust resistance (indicated by the "X"). Specifically, an IPX8 rating indicates that the device can withstand submersion in fresh water at a depth of up to 1.5 meters for 30 minutes[1][3]. This level of protection allows users to use the phone in wet conditions, such as during rain or near a pool, without significant concern for water damage.

Comparison with Galaxy Z Fold 4

While both the Galaxy Z Fold 4 and Z Fold 5 have an IPX8 rating, the Z Fold 5 introduces improvements in design that may enhance overall durability:

- Design Improvements: The Galaxy Z Fold 5 features a gapless design, which helps prevent dust accumulation—an issue that was more pronounced in previous models. This design change aims to improve the overall durability of the device, although it still does not provide any official dust ingress protection due to its IPX8 rating[2][4].

- Hydrophobic Coating: Both devices utilize a hydrophobic coating that helps repel water. However, advancements in materials and manufacturing techniques in the Z Fold 5 may offer better performance under similar conditions[1][3].

Conclusion

In summary, while both the Galaxy Z Fold 4 and Z Fold 5 share the same IPX8 water resistance rating, the latter benefits from design enhancements that could lead to better durability and user experience in wet conditions. The focus on minimizing dust ingress through improved design is a significant step forward, even though both models remain vulnerable to dust due to their lack of a dust protection rating.
