The phone dock can appeal to a larger audience.

The phone dock will be universal, meaning the design has to be generalised, meaning less attention can be put into making the dock work well with specific brands.

Phones come in many different sizes, making a bigger dock to support larger phones will exclude people with smaller ones.

For this idea to work, the product still needs to apply to as many people as possible. Picking a popular brand such as Apple or Samsung means that more people can make use of the product.

For a compromise to work, the device would need to be as big as the biggest phone supported, while still being able to support the smallest.

The smallest and the biggest phone can't be too far apart in size

For example, a phone dock could support the regular sized iPhone 13, as well as the iPhone 13 Pro Max as there is only a small size increase.
