Big phones are increasingly predominant, in fact the latest models launched on the market by the big brands generally have screens larger than 6 inches. The size you choose will depend on how comfortable you are with a larger or smaller phone.
We must also take into account their technology: we can find LCD, AMOLED or Super AMOLED screens. The use of one technology or another will also influence the battery life and clarity. AMOLED and Super AMOLED screens have a higher sharpness and, in addition, they do not waste energy when reproducing the black colour, which allows you to save a lot of battery power – especially now that the dark mode has become so fashionable.
In terms of resolution, we usually get a Full HD screen resolution, which is 1920 x 1080 pixels. You can have 4K as well but it is excessive for such a small screen. A pixel is the smallest part that an image can be divided into. If we have large screens but with low resolution, the result is to see an image with poor quality. On the contrary, a smaller screen with a high resolution will offer an excellent image quality.
So, by now, AMOLED with Full HD.
