Currently we use the Metrahit Energy, a professional single phase power quality and energy measurement digital multimeter, for our measurements. Compared with the Redmi 9A, the 9AT is supposed to have an additional microphone and consequently offer improved noise cancellation. However, the Redmi 9A gets about 3 hours more out of the 5,000 mAh battery with almost identical hardware.

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. The IPS panel is less bright and has a lower contrast, and the Redmi 9AT's battery life is also significantly lower than that of its counterpart. With security patches at the level of February 2021, the device is still quite up to date in this regard at the time of this review. The low 720p resolution results in a pixel density of only 269 ppi; consequently, content isn't very sharp. When it comes to the huge field of technology, I'm currently also interested in specializing in Java programming.Read more about the condition New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is applicable).

If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.Like the other Redmi 9 smartphones, the Redmi 9AT features a microSD card slot, dual-SIM functionality, and a 3. Although the AT model, in contrast to the Redmi 9A, is supposed to have three instead of only two microphones installed, the case is identical as far as we can see.

I immediately found their reviews to be very comprehensive, and luckily, I've even had the chance of translating them since 2019. After accounting for the operating system's space, the user is left with approximately 23 GB of available storage. The decrease in brightness is pronounced when looking at the LC panel from the sides, and viewing angles are relatively unstable.The Helio SoC has eight processor cores divided into two clusters: Four Cortex-A53 cores with a clock rate of up to 2 GHz and four Cortex-A53 cores running at up to 1. A similar behavior in terms of heat development under sustained load ensured stable frame rates in the 9A sibling model when running the GFXBench app's battery test. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . However, the scores are below the entry-level competition, which is also considerably more expensive though. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting).

The maximum brightness of the IPS display is at a solid entry level with an average of 345 cd/m², but the 9A sibling model is about 20% brighter. The deviations from the sRGB color space are relatively low, and the color temperature of the display is well calibrated too. Moreover, video content from video streaming services can't be viewed in HD quality due to the device being limited to Widevine DRM Level 3.If you find a better deal with us, or elsewhere, between now and 4th December, we will refund you the difference! The Xiaomi phone shows very good battery life in our Wi-Fi test under realistic conditions (display brightness at 150 cd/m²). If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether. 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.
