Is the Xiaomi Redmi 9AT smartphone a sham?

The Redmi 9AT is a very affordable smartphone for budget-conscious users.
The Redmi 9AT is a very affordable smartphone for budget-conscious users.
At a current price of about 89 Euros (~$106), it's almost impossible to find anything cheaper than the Redmi 9AT. However, Xiaomi cuts some corners in its entry-level phone in order to push the price below 100 Euros (~$119). Our review of the Redmi smartphone also reveals some unexpected differences compared with the Redmi 9A.

With the Redmi 9A, a very affordable Redmi smartphone passed through our test course last year. The "improved" version of the Xiaomi smartphone with the designation "Redmi 9AT" also convinces with long battery life and solid build quality in our review. This is an additional model in the Redmi 9 entry-level series. However, little information can be found about the AT model, especially regarding the differences to the Redmi 9A. Even Xiaomi doesn't list the low-budget phone on its European websites, and the Chinese online presence of the company from the Far East doesn't make mention of it either.

According to reports, the Redmi 9AT should have an additional microphone compared to the Redmi 9A and consequently offer improved noise cancellation. However, we can only see two cutouts for microphones on the Redmi 9AT. As far as we can tell, the cases of the two Redmi smartphones are identical.

Nevertheless, we can't say the same about the built-in IPS panels. The maximum display brightness of the 9AT is at a solid entry-level with an average of 345 cd/m², but the 9A sibling model is about 20% brighter and has a more homogeneous brightness distribution. With 375 cd/m², even the more realistic APL50 test, which simulates an even distribution of bright and dark areas on the LC display, doesn't improve the lower luminance. An IPS panel never achieves the perfect black level of an OLED panel due to its backlight, but the Redmi 9AT's black level of 0.45 cd/m² is visibly worse than that of the Redmi 9A, resulting in different contrast values for the panels as well.

Furthermore, we get very good runtimes with the Redmi 9AT in our Wi-Fi test under realistic conditions (display brightness at 150 cd/m²), but the Redmi 9A gets about 3 hours more out of the 5,000 mAh battery with (almost) identical hardware.

Would you like to get a detailed impression of the Redmi 9AT? If so, we recommend our review of the Xiaomi smartphone.

I have always been very passionately interested in mobile technologies, especially smartphones. Being a tech enthusiast means the half-life of my devices isn’t exactly long, and being the latest hardware is not enough to suffice as the manufacturer and operating system play a minor role – the most important aspect for me is that the device is state-of-the-art. After posting for Mobi Test I joined Notebookcheck in 2016, where I have been pursuing my enthusiasm for technology by reviewing the latest smartphone, tablet, and accessory trends.

I've been fascinated with technology ever since I got my very first Android smartphone, which was quite a while ago. The power packed into such a small footprint still amazes me. Learning to program made my understanding of technology deeper, and at the same time, it expanded my interest to the area of desktop computers and laptops. All this led me to enjoy reading and watching reviews of new devices, and that's how I stumbled upon Notebookcheck. I immediately found their reviews to be very comprehensive, and luckily, I've even had the chance of translating them since 2019. When it comes to the huge field of technology, I'm currently also interested in specializing in Java programming.
