With the popularity of social media skyrocketing, the need to post unique photos has risen. That is why Redmi 9 comes with a 13MP (wide) + 8MP (ultrawide) + 5MP (macro) + 2MP(depth) AI Quad camera system. With four camera lenses, Redmi 9 can take a variety of photos compared to other smartphones with fewer cameras. The 13MP camera is the main camera lens. As expected, the main camera takes amazing clear HD images. No matter the lighting condition, any photos that are taken by the camera are clear and bright. The 8MP ultrawide lens is for taking wide-angle photos. A normal camera lens takes a 75° angle photo and the problem with that angle is that it's a small frame that is not good for group photos or scenic photos. To take wide-angle photos, you need a wide-angle camera. With a wide-angle camera, you get a 118° angle that fits everything on the frame without you moving back to capture the whole scene. The macro camera is for taking close-ups of small objects. Trying to capture close-ups of small objects can be difficult using a normal camera lens. The more you move your smartphone towards the subject the more distorted the image becomes. With a macro camera, you can take clear, detailed images of up to 2.5cm of the subject without losing clarity. The depth camera captures beautiful portrait photos. The camera blurs the background to produce a beautiful bokeh effect which makes the subject. With the subject the center of attention instead of the background, you get amazing portrait photos. Tear-Drop Display. Redmi 9 has a 6.53" inch teardrop display. The teardrop display has a 1080p resolution making the display a Full HD display. With a Full HD display, you get to experience colors as they appear naturally in the environment. The colors are vibrant and bright providing an immersive feeling that improves your viewing experience. You no longer have to watch poor resolution content with Redmi 9. To protect your eyes, Redmi 9 display comes with Blue Light protection that blocks harmful blue light from reaching your eyes. Blue Light is a harmful light emitted by displays. Too much Blue Light causes eye strain and damages the retina which can lead to future complications. With blue light protection, you can use your smartphone for long periods with straining your eyes. Powerful Performance. Redmi 8 was a good performing smartphone. Compared to other smartphones that were at its price range, Redmi 8 offered better processing power that matched smartphones above its price range. Redmi 9 replaces Redmi 8 with big improvements in terms of performance. Redmi 9 has an Octa-core Mediatek Helio G80 processor that clocks at 2.0GHz. The processor offers a 107% increase in performance compared to Redmi 8. The CPU is 82% faster than the previous generation while the Mali-G52 MC2 GPU increases graphics performance by 309%. This is great for gamers who will get to experience better graphics when gaming and improved overall gaming experience. Tabs are usually supported by the RAM and the more tabs a smartphone can handle being open at the same time greatly depends on the size of the RAM. The RAM is what enables you to multitask without your phone lagging. A poor RAM makes your smartphone lag the moment you open multiple tabs at the same time. With a 4GB RAM, Redmi 9 has enough RAM capacity to make sure you operate all your tabs simultaneously without any lagging issues. Big 5020mAh Battery. A good smartphone should have a battery that can last the whole day on a single charge. Since we carry our smartphones everywhere, it can be a headache trying to look for a charging place in the middle of the day when you are working since your battery power ran out. Having a smartphone with a poor battery may force you not to do some activities, like browse the internet, for fear that your battery power will run out. But if your smartphone has a good battery that lasts the whole day, you can browse the internet, play games and watch videos without any worries. Redmi 9 has a large 5020mAh battery that lasts the whole day, no matter what activities you do on your device, on a single charge. With the battery, you can have 185 hours of music playing, 31 hours of calling, 19 hours of continuous navigation, or 19 hours of video playback. The disadvantage of having a smartphone with a large battery is that charging time is longer compared to smartphones with small batteries. This can be a headache when you want to use your phone but it takes hours to charge. To solve this problem, Redmi 9 comes with 18W Fast Charging that power-ups your smartphone quickly so that you are never far from your smartphone.
