The Xiaomi Mi 10i is the latest smartphone in the town and is also the first major smartphone launch of 2021. The Xiaomi Mi 10i brings flagship-grade specifications such as 108MP primary camera, 120Hz refresh rate, 33W fast charging and more to the affordable segment. The sub Rs 30,000 last year was dominated by OnePlus Nord, Samsung Galaxy M51, and also Pixel 4a. 

In this article, we will have a look at detailed specifications of the Xiaomi Mi 10i, OnePlus Nord, and Samsung Galaxy M51 and compare them. These phones will now rival against each other in the Rs 30,000 segment. 

While Xiaomi is making its comeback to the segment after Redmi K20 Pro, OnePlus made its debut to launch the Nord last year starting at Rs 24,999. Samsung on the other hand went ahead and added Galaxy M51 with a massive battery and Snapdragon chipset which performed really well.

The Xiaomi Mi 10i sports a very similar design as the Poco X3. There is also a circular camera module which reminds us of the OnePlus 7T especially in the Pacific Sunrise colour option. The back is made up of polycarbonate material which is protected by Corning Gorilla Glass 5. It gives a smooth finish and is surprisingly not a fingerprint magnet. The Mi 10i is available in Pacific Sunrise, Atlantic Blue and Midnight Black colour options. 

The OnePlus Nord comes with a glossy glass body with Corning Gorilla Glass 5 on the back. Colour options include Blue Marble, Gray Onyx, and Gray Ash. Holding the phone feels solid and comfortable. It is also the slimmest and lightest phone among the three phones in the list. 

The Samsung Galaxy M51 offers glasstic back which offers better grip and it is not as slippery as other phones with a glass back. To make it even worse, Samsung also misses out on providing a complementary silicone case in the box. The device is heavy but well balanced and you’ll get used to it once you start using it.

Xiaomi has retained the display from the Mi 10T smartphone. It offers a 6.67-inch Full HD+ (2400 x 1080p) LCD screen with 120Hz refresh rate. The AdaptiveSync feature also makes its way to the Mi 10i which switches between 30Hz, 48Hz, 50Hz, 60Hz, 90Hz and 120Hz to match with the content. It can go up to 450 nits. Apart from that, the display is also TÜV Rheinland certified for low blue content consumption, supports HDR10+ content as well as HD streaming. And lastly, it is protected by Corning Gorilla Glass 5. 

The OnePlus Nord is still the cheapest phone with a high refresh rate display and AMOLED panel. It offers a 6.44-inch Fluid AMOLED screen with Full HD+ (2,400 x 1,080p) resolution. You get a 90Hz refresh rate panel for smoother scrolling experience. The phone is tall with a 20:9 aspect ratio. It is capable of handling HDR content and comes with support for sRGB, DisplayP3, and AMOLED wide gamut screen calibration modes. The display is also protected by Gorilla Glass 5. 

Samsung on the other hand offers a Super AMOLED panel but misses out on the high refresh screen. You get a huge 6.7-inch Full HD+ Super AMOLED Plus Infinity-O panel with a tall 20:9 aspect ratio. It is protected by a layer of Gorilla Glass 3, which is slightly outdated. The handset also supports HD streaming and HDR content.
