Comparison review
The Sony Xperia 1 III has a general score of 93.3, which is better than the Xiaomi Redmi Note 9S's 79 score. Both of these phones come with the same Android 11 OS (operating system), so you shouldn't notice any difference in that aspect. The Sony Xperia 1 III construction is newer, just a little thinner and somewhat lighter than Xiaomi Redmi Note 9S.
The Xperia 1 III counts with a better display than Xiaomi Redmi Note 9S, because although it has a quite smaller display, it also counts with a lot better 1644 x 3840 resolution and a lot better display density. Xperia 1 III counts with just a little better processing power than Xiaomi Redmi Note 9S, and although they both have the same number of cores, the Xperia 1 III also has 8 GB more RAM.
The Xperia 1 III has a way bigger memory to install games and applications than Xiaomi Redmi Note 9S, because it has a SD memory card expansion slot that supports up to 1 TB and 192 GB more internal memory. Xiaomi Redmi Note 9S features just a bit better battery lifetime than Sony Xperia 1 III, because it has a 12 percent greater battery capacity.
Xiaomi Redmi Note 9S shoots clearer photographs and videos than Xperia 1 III, because although it has a tinier camera sensor taking worse quality videos and photographs, lower 30 fps video frame rates and a smaller aperture which is not good for capturing pictures and video in low light environments, and they both have the same (4K) video quality, the Xiaomi Redmi Note 9S also counts with a much better resolution camera.
Although Sony Xperia 1 III is a better device, it is a lot more expensive than Xiaomi Redmi Note 9S, and it doesn't have such a good quality/price relation as Xiaomi Redmi Note 9S. If you want to save some dollars, you can buy Xiaomi Redmi Note 9S, giving up a couple features and specs, but you'll get the most out of your money.
