The Redmi 9 gets added protection with corrosion proof ports, rubberized seals and 380V surge protection Enjoy more screen-time with reading mode 2.0 with a TÜV Rheinland certified display that protects your eyes from harmful blue light

Scan over the specs for the cameras and you'll see that some of the numbers are pretty different, but these systems have a lot in common. They both have a main camera paired with an ultra-wide camera and then a macro camera. A depth sensor sits in support on both. The Redmi Note 9 is an incremental step forward over the Redmi 9, which has slightly older hardware. The CPU on both these devices is essentially the same, but the Redmi Note 9 has slightly more graphics power, so likely to be a little stronger in gaming performance.

What is it like to use the Redmi 9?

AI scene detection enabled camera’s delivers clear and detailed pictures with 13MP primary camera and 2 MP Depth sensor at the rear and a 5MP selfie camera in the front

The smartphone is fueled by a Non-removable Li-Po 5020 mAh battery + Fast charging 18W. The phone runs on the Android 10, MIUI 12 operating system providing smooth operation of the device. It seems like fewer and fewer of us can justify spending flagship money on flagship phones, and with handsets like the Redmi 9 around, you really don't need to – it's a fantastic little budget phone, with a screen and design that impress, and camera quality and performance levels that are good enough for a budget phone. The device is equipped with sensors such as fingerprint (rear-mounted), accelerometer, gyro, and proximity. The smartphone features Infrared port, 2.0, Type-C 1.0 reversible connector, USB On-The-Go, Yes (market/region dependent), and Bluetooth 5.0, A2DP, LE. Every smartphone is a compromise between price and everything else, and when it comes to this handset that's most noticeable in low light camera performance and the overall speed of the device. However, we were perfectly happy using the Redmi 9 as a phone for a few days, with only the occasional moment of frustration at a slowdown.

Clear phone calls even in noisy environments refers to simulated noisy environments in Xiaomi labs. We don't like the MIUI skin that Xiaomi puts on top of Android (Android 10 in this case) all that much, but your mileage may vary – it's just a bit too garish and interfering for our tastes, but there's nothing here that would necessarily put you right off the phone. You do get quite a lot of Xiaomi's own apps on board out of the box, but they're easy enough to uninstall or ignore if you don't like them. Realme 7, for example, recorded 9 hours 2 mins, and the Pro version 12 hours 5 mins. This is actually one of the lowest scores we’ve seen since we began using the PCMark benchmark.

Inheriting the Aura 360 design legacy, the Redmi 9A maintains a premium look with an easy to hold hand-feel

Battery standby time is tested by measuring the time of the smartphone reaching 0% power from 100% under a test scenario. Test results are collected from Xiaomi lab. Actual results may vary as a result of environmental changes. The Redmi 9 we've not had that chance to test, but if it's using the same AI camera system as the Note 9 we'd expect similar performance from the 13-megapixel camera, but the aperture here might mean it's not good at dealing with lower light conditions. However, it's worth considering that the Redmi Note 9 has more powerful SoC hardware to support the camera - and that might give it the edge over the Redmi 9. The term "Full Screen Display" indicates that the phone has a high screen-to-body ratio in comparison to traditional Xiaomi phones. The screen-to-body ratio was obtained from Xiaomi laboratory. The results may vary as methods of measurement may vary within the industry. The smartphone comes in 6.53 inches size and the display is IPS LCD capacitive touchscreen that provides 1080 x 2340 pixels resolution. The screen of the device is protected by Corning Gorilla Glass 3.Redmi 9 comes with a large 16.58cm (6.53) HD+ IPS Display that delivers an immersive viewing experience The battery capacity is different however, and the larger battery in the Redmi 9 is likely to mean that it lasts longer. Both support 18W fast wired charging, but the Redmi 9 only comes with a 10W charger in the box, whereas the Note 9 has a 22W charge - although again there may be some regional differences here.
