The Mi 8 Pro is the top model of 2018, still considered one of the most stylish in Xiaomiโ€™s lineup, with a transparent rear panel underneath which the deviceโ€™s board is visible (although itโ€™s actually just a decorative element).

๐ŸŽฎ Xiaomi Black Shark: a gaming smartphone with active cooling

The Black Shark is Xiaomiโ€™s first gaming smartphone to be launched in partnership with Black Shark Technology, with a key feature of liquid cooling that prevents overheating during long gaming sessions, but thatโ€™s not the only benefit.

The device features the same Snapdragon 845 as the Mi 8 Pro, but with improved heat sink.The screen supports HDR technology and has an increased touch rate (240 Hz), which is important for dynamic games like PUBG Mobile or Call of Duty.

  • โœ… Pluses: ๐ŸŽฎ Optimized for games: no lags and slowdowns ๐Ÿ”‹ Large battery (4000 mAh) - enough for 6-8 hours of play ๐ŸŽง 3.5mm headphone jack (rare for flagships) ๐Ÿ–ฅ๏ธ Support for external gamepads

To test the performance of the Black Shark cooling system, run a heavy game (such as Genshin Impact) for 15-20 minutes. If the case is very hot (more than 45 ยฐ C), then the liquid cooling is not working properly.

๐Ÿ–ฅ๏ธ Xiaomi Mi Mix 2S: frameless

The Mi Mix 2S is a smartphone with minimal bezels (91.3% screen-to-body ratio) and a ceramic body that looks premium even today. Unlike the Mi 8 Pro, there is no neckline (" bangs"), and the front camera is hidden in the bottom frame.

The device runs on the Snapdragon 845 and has a dual camera with optical zoom, but its main advantage is the design. The ceramic case is scratch resistant, but it is slippery (use a case is recommended).

  • โœ… Pluses: ๐Ÿ–ฅ๏ธ Frameless design with minimal frames ๐Ÿ“ท Good camera (12+12 MP) 2ร— zoom ๐Ÿ›ก๏ธ Ceramic case (stronger than glass) ๐Ÿ”Š Stereo speakers with good sound

Who's right for? For those who value unique design and are willing to pay a premium for it. If you want a smartphone that stands out, the Mi Mix 2S is a great choice. But if autonomy or the camera is important, you better look at the Mi 8 Pro.

How to distinguish the original ceramic version from a fake?

๐Ÿ“ธ Xiaomi Mi A2: Pure Android and compactness

The Mi A2 is a unique model in Xiaomiโ€™s lineup, as it runs on pure Android One without a MIUI shell. This means that the device received updates directly from Google, and the interface is devoid of excess software.

The smartphone is equipped with a Snapdragon 660 processor, which still copes with everyday tasks (social networks, messengers, light games). The camera here is dual (12+20 MP), but without optical zoom. The main advantage is the compactness (weighing only 166 g) and a metal body.

  • โœ… Pluses: ๐Ÿค– Clean Android One without unnecessary apps ๐Ÿ“ Compact and lightweight (166g) ๐Ÿ“ท A good camera for your class. ๐Ÿ”‹ Quick Charge 3.0 Quick Charge

One of the problems with the Mi A2 is that it overheats when it's under a lot of pressure, and it's a metal body and a small battery, but in everyday use (calls, messengers, photos), it behaves consistently.

Who's good for? For those who are looking for a compact smartphone with pure Android and don't need high performance. If you want stable work without lags and unnecessary applications, the Mi A2 is great. But for games or photos, you better choose another model.

๐Ÿ’ฐ Xiaomi Redmi Note 5: the best budget 2018

The Redmi Note 5 is the most affordable smartphone in our review, but itโ€™s also one of the most balanced.It runs on a Snapdragon 636 processor that still pulls most everyday tasks, and a 4,000mAh battery provides two-day battery life.

The device has a metal case, fingerprint scanner and dual camera (12+5 MP).The main advantage is the price / quality ratio. On the secondary market, it can be found for 7-10 thousand rubles, making it an ideal choice for those who are looking for an inexpensive but reliable smartphone.

  • โœ… Pluses: ๐Ÿ’ฐ The lowest price among the 2018 models ๐Ÿ”‹ Large battery (4000 mAh) - lasts for 2 days ๐Ÿ“ Convenient size (5.99), but more compact than flagships) ๐Ÿ“ท A decent camera for its class

One of the common problems of Redmi Note 5 is the wear of the battery. After 6 years of operation, its capacity can fall to 60-70% of the original. However, replacing the battery will cost only 1-1.5 thousand rubles., which is disproportionate to the price of the smartphone itself.

โš ๏ธ Note: In the secondary market, Redmi Note 5 Pro (Indian version) is often sold under the guise of the usual Redmi Note 5. You can distinguish them by the processor: the Pro version is Snapdragon 636, and the usual Snapdragon 625.

For those looking for the most budget-friendly yet reliable smartphone for calls, social media and easy gaming. If you donโ€™t need top-end specs, but autonomy and price are important, the Redmi Note 5 is the best choice.

๐Ÿ’ฐ Should you buy Xiaomi 2018 in 2026?
It depends on your tasks: โœ… Worth it: if you need a budget smartphone for calls, social media, and easy gaming; if youโ€™re looking for a device to experiment with firmware; if you care about design (e.g. Mi Mix) 2S Mi 8 Pro). โŒ Donโ€™t: If you need top-end performance for modern games; if you need long-term update support; if you plan to use a smartphone for longer than 1-2 years.

๐Ÿ”ง Where to buy used Xiaomi: Avito, Yula or specialized forums?
Each option has pros and cons: Avito/Yula: a large choice, but high risk of running into fraudsters or a smartphone in poor condition.

Service centers: some SCs sell restored smartphones with a guarantee. Plus - you get the device in good condition, minus - the price is higher than the market. Our advice: if you buy a smartphone, only take a ticket after checking.
