The Pixel Fold, known internally by the codename Felix is susposed to challenge Samsung's market-leading foldable phone business and will have the "most durable hinge on a foldable" phone.

While that is all well and good, this durable hinge makes the phone cost $1,700.  While this is cheaper than Samsung's $1,799 Galaxy Z Fold 4 it is no where near close to getting consumer friendly.

Google plans to market the Pixel Fold as water-resistant and pocket-sized, with an outside screen that measures 5.8 inches across, according to the documents.

Photos viewed by CNBC show that the phone will open like a book to reveal a small tablet-sized 7.6-inch screen, the same size as the display on Samsung's competitor. It weighs 10oz, slightly heavier than the Samsung Galaxy Z Fold 4, but it has a larger battery that Google says will last for 24 hours, or up to 72 hours in a low power mode.

The Pixel Fold is powered by Google's Tensor G2 chip. That's the same processor that launched in the Pixel 7 and Pixel 7 Pro phones last year.
