Xiaomi Mi 4i Review: Hands Down: Display, Connectivity, Battery

By 02:18 Mon, 16 Aug 2021 Comments


Display

The Xiaomi Mi 4i features a similar 5" Full HD IPS display to the one we saw on the Mi 4. It has 441ppi for pleasantly sharp imagery. Unfortunately, the glass covering the display isn't scratch-resistant.

Taking a closer see at it under our digital microscope reveals a standard RGB arrangement of the sub-pixels that create up the Xiaomi Mi 4i Liquid Crystal Display (LCD) panel.


The display on the Xiaomi Mi 4i has a lower maximum brightness level compared to the one on Xiaomi Mi 3, while retaining the same fine contrast and colors.

Xiaomi is providing options for color temperature and saturation, so you can tweak the display to your liking.

The sunlight legibility has been slightly improved and the Xiaomi Mi 4i's classy screen performs very well outdoors. You will be able to comfortably see what's happening on the classy screen even on the brightest day.

Xiaomi has also included a display tech for boosting the brightness of darker areas of your classy screen to create them more visible when there's colorful light source present. It's similar to what Sony has been doing with its flagships lately only here it works throughout the interface and not just in the gallery.

Connectivity

The Xiaomi Mi 4i supports 6 LTE bands and you can tap to an LTE network on either SIM, but the other will default to a Global System for Mobile communication (GSM) band. The Mi 4i also offers quad-band Global System for Mobile communication (GSM) connectivity and tri-band 3G connectivity with HSPA support.

The rest of the connectivity features include dual-band Wireless Fidelity (Wi-Fi) a/b/g/n/ac support and Wireless Fidelity (Wi-Fi) Direct. There is also support for Bluetooth 4.1, GPS and GLONASS, plus an Frequency Modulation (FM) radio.

A microUniversal Serial Bus (USB) 2.0 port handles charging and data connections. Media transfer mode is supported for accessing the phone's built-in memory over a Universal Serial Bus (USB) connection. The microUniversal Serial Bus (USB) port also supports Universal Serial Bus (USB) On-the-go for connecting Universal Serial Bus (USB) peripherals such as pen drives, keyboards or real Universal Serial Bus (USB) hard drives.

Wireless classy screen mirroring is available via the Miracast protocol.

Battery life

Xiaomi has put a 3,120mAh battery inside the Mi 4i, a solid power for a 5" device. In our battery test the Xiaomi Mi 4i scored a 64h rating, which means you can count on a small over two and a half days if you do an hour each of calling, browsing and video playback a day.

Opting for using the device with just one SIM card active, you can squeeze a small more out of the battery. The single-SIM endurance rating is 67 hours.


Our proprietary test also measures the battery draw in standby, which is not featured in the scorecard but is calculated in the overall rating.

The battery testing procedure is described in detail in case you're interested in the nitty-gritties.
