Galaxy A02s vs Xiaomi Mi 9: Specs & Scores

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 Xiaomi Mi 9 is 2.9 inches (74.7 mm) tall, 6.2 inches (157.5 mm) wide, and 0.3 inches (7.6 mm) thick.

The device weight will effect how quickly you tire from holding it, and how much stress is put on your wrist. The lighter it is, the longer you can hold it without feeling tired. Also, less stress on your wrist will make using it easier and more pleasant. Unless the weight is right for you, it might put too much strain on your body and make using it more stressful.

Screen size influences how well you can control your device, as well as how clear the display is. With a large screen, the text and buttons in apps will display large enough so you'll be less likely to accidentally tap the button next to the one you were aiming for. Plus, you'll be able to enjoy more high-impact visuals for games and movies.

The screen size on the Galaxy A02s is 6.5 inch, and 6.39 inch on the Xiaomi Mi 9. The screens of the Galaxy A02s and Xiaomi Mi 9 are roughly the same size, and so the ease of pressing app buttons are the same on both devices. Because of this, it is better to compare them based on other aspects of performance and function.

Pixel density influences how nice your device's screen looks, with high pixel densities making screens look more beautiful, and letting you get more out of your games and movies. Plus, the nicer you screen looks, the less strain you'll be putting on your eyes, so you'll tend to be able to use your device for longer before your eyes get tired.

If you want to choose a smartphone that is gentle on your eyes with a display that shows text and images clearly, we recommend that you buy the Xiaomi Mi 9 rather than the Galaxy A02s.

Battery performance has a big effect on the battery life of your device. However, a high battery capacity doesn't necessarily mean a long battery life. Rather, the rate of power consumption needs to be taken into consideration as well. The larger the screen and the higher the CPU performance, the higher the rate of power consumption on your battery.

Your CPU's speed will influence the processing power of the applications you run, and together with the number of cores in the CPU, as well as its clock frequency, will determine the processing power available for apps. The higher these performance factors, the smoother your games and apps will run. Conversely, if these factors are too low, your apps and games will be sluggish and struggle to run.

Storage capacity determines the amount of data you'll be able to save on your device. The more storage you have, the more photos you can take and the more apps you can install. Plus, if your smartphone is compatible with SD cards, then you can increase the amount of available storage. However, SD cards have a slower writespeed, making them less desirable in terms of performance, and users should be aware that it won't be possible to transfer all kinds of data to the card.
