Foldable phones are shocking, and not just because they introduce a completely new design. With prices that double or even more than double the cost of today's $1,000 4G flagship designs, these bendable devices are shooting the price of phone ownership into the stratosphere. In 2016, Samsung's most expensive Note phone cost $850, while the price of Apple's most expensive iPhone soared from $769 in 2016 to $1,099 in 2018, a 43 percent increase.  

The possibility of cheaper Huawei foldable phones was one new Mate X detail that trickled out at a small group session for journalists after Huawei's press conference here in Barcelona. Another was an insight into why the phone is so expensive in the first place, surpassing even the price of Samsung's new Galaxy Fold, which will sell for $1,980. While a foldable design and high-end specs do inflate the price, the key might lie in the Mate X's shape.
