Motorola's Razr reboot is undoubtedly a nostalgia-inducing wonder to behold. It has the same form factor as that of the iconic 2004 Razr, but features modern-day smartphone tech such as a foldable display.

By now, everybody knows that it won't be cheap, that it won't be a high-end phone but instead have midrange specs, and that it's different from the original Razr in many ways (including the hinge). Despite all the available information about the device, though, some things remain unknown at the moment.

Here are some details about the 2019 Razr foldable that remain unknown or unconfirmed at the moment, as per CNet:

Display durability

The new Razr uses a plastic OLED display with a hard coating on top. It doesn't use glass, making it more vulnerable to damage. Those who have no idea how vulnerable a folding plastic screen is should look back to the time when Samsung's Galaxy Fold made its first outing and went back home in embarrassment, and when the redesigned Galaxy Fold still failed.

That said, it's unclear as to how durable the Razr's display will be. Will it be able to withstand daily use and stay safe from scratches and other possible damages?

Battery life

The new Razr has a measly 2,510 mAh battery. Motorola claims it's enough to last for a day, but will it really? The small battery has to power two screens: a small screen when the device is folded, and a larger screen when it's open. Can the battery sustain that?

Splash-proof

Motorola said the new Razr has a splash-proof display, but hasn't revealed any IP rating for water resistance. It has nanocoating alright, but will that be enough to protect the Razr from accidental splashes?

Stress Test details and Durability

Motorola hasn't specified the number of times it folded and unfolded the Razr in a stress test. It only said it unveiled the device because the handset was “ready” and that “it will last for the average lifespan of a smartphone.” Those promises won't mean anything if it breaks during daily folding and unfolding, though. It costs twice the price of a regular smartphone – it better last that long.

Colors

The original Razr came in a variety of colors, including pink. Will the Razr reboot come in a selection of colors not limited to “noir black”?

Is it worth the cost?

Lastly, and more importantly, will the features, promised durability, and apparent nostalgia-inducing beauty be enough to get people to part with $1,500? Will it be durable and comfortable enough for use as a primary phone everyday?
