Redmi Prime 9 Review


Regardless of whether you’re looking for a smartphone for the first time or you’re an experienced user looking for a great mid-range device, you may want to consider the Redmi Prime 9. The phone offers an attractive design, excellent battery life, and a solid quad camera setup, making it a great choice for first-time smartphone users.

Quad camera setup

Apparently, the new Redmi Prime 9 has a quad camera setup on its back. This is an arrangement that includes an 8MP ultra-wide sensor, a 5MP macro sensor, and a 2MP depth sensor. While it isn’t the best camera setup in the world, it’s better than most mid-range devices.

The main sensor is an f/2.2 lens that captures good shots, but it has a low resolution. While this sensor is good for landscapes, it isn’t very good for taking pictures of people, because it can’t produce as much detail as other cameras in this price range.

The secondary sensor of the quad camera setup is an 8MP ultra-wide sensor that captures a broader field of view than the main sensor. However, it isn’t as detailed as the main sensor, and it can produce some extra noise.

18W fast charging

Using an 18W fast charger on your Redmi Prime 9 can increase your battery life considerably. A 10W charger takes three hours to fully recharge your phone, while an 18W fast charger can do the job in just over two hours.

The battery on the Redmi 9 isn’t the largest, but it still lasts for an entire day on moderate usage. The battery can last over 19 hours of video playback and 31 hours of phone calls. In addition, it has a fast charge feature that allows you to charge the device from 0% to 80% in a matter of minutes.

In terms of sound quality, the Redmi 9’s speaker is just average. However, it does have a headphone jack, so you can plug your headphones into it and improve your movie experience.

90Hz LCD with an adaptive refresh rate

AdaptiveSync is a display technology that allows three steps of display refresh rate adjustment. The first step is a low-refresh-rate setting that is used for reading or watching videos. The second step is a higher refresh rate setting for gaming or watching videos.

The third step is an automatic switch that automatically changes the refresh rate depending on the content being watched or read. This makes content smooth and eliminates edge cases.

90Hz and 120Hz displays are common features in modern smartphones. They are more than three times faster than a 60Hz panel, but they are not perceptible to the naked eye.

Some of the best mid-range phones, including the Redmi Note 10, use a 90Hz refresh rate. This makes games and videos smooth. However, there are occasional stutters and the color reproduction is not as vibrant as on other LCD panels.

Good battery life

Despite being priced at just Rs 9,999, the Redmi 9 Prime offers decent battery life. In our tests, the phone managed to last more than two days on moderate usage. The battery offers up to 19 hours of video playback, 185 hours of music playback, and 31 hours of calls. In addition to the battery, the phone comes with an AI-powered quad camera setup that includes a 13 MP primary camera, an 8 MP ultra-wide lens, and a 2MP depth sensor.

The screen of the Redmi 9 Prime comes with a resolution of 2340 x 1080 pixels. This enables it to provide a good viewing experience, especially for gamers. However, the screen’s brightness is not sufficient in daylight.

The Redmi 9 Prime is powered by a MediaTek Helio G80 octa-core SoC. This processor helps the phone to run graphically-intensive games smoothly.

Lacks a dedicated Night mode

Dedicated Night mode is a common feature on budget phones. However, the Redmi Prime 9 fails to provide a dedicated Night mode. This makes the phone less appealing as a low-light photographer.

Night mode is designed to add brightness to photos and videos taken in low light. However, the images taken with this mode aren’t very clear. Moreover, the night mode requires the smartphone to remain still for almost two seconds. This could cause issues in certain apps such as Facebook and Snapchat.

The camera app on the Redmi 9 Prime is relatively simple. It includes features such as Wide-angle, Pro, Slow motion, and Portrait modes. However, the camera app doesn’t provide a lot of useful information about the camera.

The rear camera on the Redmi 9 Prime includes a 13 MP main camera, an 8MP ultra-wide-angle lens, and a 2MP depth sensor. Combined, these sensors provide decent performance when outdoors, although the output from the main camera is a bit weak.
