Compare Performance and Usability

Size comparison of "Samsung Galaxy M51 128GB" and "vivo V15 (2019) 128GB". Which one would you choose?

Your device's size has a huge influence on how easy it is to hold or to operate with one hand. The smaller your device's width, the easier it will be to hold, but you'll also need to take device thickness into account. And when the length and width are both smaller, you'll find that it's much easier for you to operate it one-handed, since your fingers will find it much easier to reach where you want them to. On the other hand, longer lengths and wider widths might lead to devices that are hard to carry in your pocket, bulky even when you keep them in your bag, and all around less portable.

The "vivo V15 (2019) 128GB" is 75.9mm tall, 161.2mm wide, and 8.5mm thick.
