2. Overall Evaluation of the iPhone 12
- Design of the iPhone 12
The materials chosen to finish the iPhone 12 include an aluminum frame and a glossy glass back (a difference from the Pro version – frosted glass back).

Instead of curved edges, the iPhone 12 leans towards a more square design but still feels comfortable and doesn't cause discomfort when held, remaining comfortable and not sharp enough to cut the hand as some review sites claim.
In terms of colors, the iPhone 12 comes in 6 versions including black, white, red, green, blue, and purple. Among them, the red leans towards orange, the green is quite pale while the blue is very deep.
- Screen of the iPhone 12
The iPhone 12 features OLED screen technology, which improves display quality significantly. Compared to its predecessor, the iPhone 11's screen, the iPhone 12's screen no longer suffers from any visible flaws, resulting in a highly satisfying viewing experience.
Unfortunately, the iPhone 12's display only has a 60Hz refresh rate. Meanwhile, many Android smartphones, even at lower price points, are equipped with 120Hz screens. The difference between using a 60Hz and 120Hz display is like night and day – once you've experienced 120Hz, going back to 60Hz feels disappointing.
- Performance of the iPhone 12

There's no need for extensive debate or deep discussion; the Apple A14 Bionic chip in the iPhone 12 delivers incredibly smooth and satisfying performance. It provides ample power and energy for users to enjoy the best gaming experience. Therefore, in everyday tasks, the iPhone 12 also offers nimble processing capabilities.
- Battery of the iPhone 12
With a battery capacity of 2815 mAh, the iPhone 12 provides enough energy for a day of usage. Despite its 5G support, the iPhone 12's battery remains stable, mainly due to its 60Hz refresh rate screen. Currently, since the majority of Vietnamese users still use 4G connections, there are hardly any factors that could significantly drain the iPhone 12's battery.
- Camera of the iPhone 12
The iPhone 12 still features a dual-camera setup similar to the iPhone 11, meaning it still lacks a telephoto camera. However, in real-world photo-taking experiences, the iPhone 12's camera performs exceptionally well, producing even better results than the iPhone 11, especially in low-light conditions.

The improvement from the Apple A14 chip has enabled the iPhone 12 to capture photos faster, produce better bokeh effects, and record videos more smoothly and seamlessly.
