Water resistance
The next factor is water resistance. Many flagship Android phones now have an IP rating for certified water resistance. The OnePlus 6 notably did not have an IP rating, even though it was splash resistant. According to Mr. Lau, the OnePlus 6T is more water resistant than any of its predecessors, and it can survive an accidental drop in the sink or a splash during a rainstorm. However, it won’t have an IP rating because the cost to go through official IP certification is not worth it for OnePlus.
Mr. Lau stated that apart from few users, most users don’t use their phone in contexts like swimming. Asking other consumers to pay $30 more as an example for the sake of an IP rating to accommodate the few is unreasonable, according to him.
