Redmi K30 has some impressive specs for a phone that costs only $230. The device is powered by a Snapdragon 730G processor from Qualcomm, a 4500mAh battery with 27W fast charging. For display, it uses IPS LCD with 120Hz refresh rate. This is one of the cheapest 5G phones you can buy right now, but of course, this 5G supports depends on the availability of the 5G network in your area. With a 4500mAh battery, you can expect to deliver an incredible battery life. But due to a higher refresh rate, you may found yourself charging after a half-day. On an average day, it can get about six hours. If you degrade the refresh rate to 60Hz, it will surely save some battery life.
The display is a 6.67-inch 1080 pixel display panel. You won't get the pure black and white if you go for less display but that doesn't mean the screen is bad. The Redmi K30 has four cameras on the rear side, and the two on the front. There's the new 64MP Sony IMX686 - a direct successor to the popular 48MP IMX 586, an ultrawide 8MP sensor, a 2MP macro camera, and a 2MP depth sensor. For the front camera, you get a 20MP lens and a 2MP depth sensor. The selfie camera produces sharp pictures in good light, but the flat color profile doesn't look natural on skin tones. If you are a big selfie person, you may want to apply some kind of filter before sharing these online. In low light circumstances, you will see a decent amount of smearing. Although the phone has a decent portrait mode that produces much sharper pictures.
The Redmi K30 is running MIUI 11, based on Android 10. MIUI is fairly customizable, but many Western users probably won't like it as much, especially if you're used to stock Android, as it tries to act like iOS in a lot of ways. By default, there is no app drawer, though you can turn it on in settings. The most annoying thing for me is the fact that you need to press a settings button to get into the settings. There is a cool feature on the Redmi K30 called Mi Share, which allows you to seamlessly transfer files between other Xiaomi, Vivo, Realme, and Oppo devices. This is effectively Apple's AirDrop, so it's nice that these manufacturers have worked together to make file transfer a lot easier.
