Frequent questions about the screen diagonal: debunking myths
There are many misconceptions about the size of smartphone screens, and we'll look at some of the most common ones.
- "The more inches, the better." Not always. For small hands, 6.67 inches can be uncomfortable, and for video viewing, the difference between 6.5 and 6.7 inches is almost imperceptible.
- "AMOLED better IPS The Redmi Note 9 Pro has a IPS-matrix that loses AMOLED in contrast, but wins in natural color reproduction and the absence of the effect of "burnout".
- "Full HD+ resolution is enough for any screen." At diagonals over 6.5 inches, you can see pixels on close inspection, but at a standard distance (25-30 cm), this is not critical.
Another popular question is, "Why does the battery go down faster in big-screen games?" The fact is that a 6.67-inch matrix requires more power to illuminate, especially at high brightness. In the Redmi Note 9 Pro, this is partially offset by a capacious 5,020 mAh battery, but when used intensively, the difference is noticeable.
