4 reasons foldable phones are actually stronger than you think

I’m not going to mince words — foldable phones are still more vulnerable than conventional ones at the moment. Their designs revolve around hinges, which create an entry point for liquids and dust that phone makers have to get creative about protecting. Conversely, many regular smartphones now have an IP68 rating, meaning they’re effectively dust- and waterproof in most scenarios. A few of them, like the OnePlus 13, have an even tougher IP69 certification — you can even spray them down if you drop them in mud.
