Xiaomi Redmi 3 Review: Precious Little One: Display, Battery Life, Connectivity

By 07:39 Mon, 16 Aug 2021 Comments


Display

The Xiaomi Redmi 3 features a 5" HD IPS - 0.3" bigger than the one on the Redmi 2. The resolution is the same and on the larger screen, that means a slightly lower pixel density of 294ppi. That's still borderline Retina-grade, and it is still more than enough for crisp images and sharp text.

Taking a closer see at it under our digital microscope reveals a standard RGB arrangement of the sub-pixels that create up the Xiaomi Redmi 3 Liquid Crystal Display (LCD) panel.


Unfortunately, there is no information on the glass covering the display, and there is a fine chance it isn't of the scratch-resistant kind.

The Xiaomi Redmi 3 has a relatively high maximum brightness of 520nits. At the lowest level, the classy screen is also spectacularly dim as well - 1.2nits.

With an average deviation (DeltaE) of 5.2 the screen's color accuracy is about average. By sliding the screen's color temperature all the way to Warm, we were able to acquire out better color rendering, which we'd consider fine all thing's considered. The Avg. Delta E, in this case, falls to 3.8 (remember it needs to be below 3 to be considered calibrated color output), but it comes at the expense of the maximum brightness, and it gets lower to 488nits.

Outdoors, the Xiaomi Redmi 3 is an above average performer regarding sunlight legibility. The glass on top of the display is reflective, but most of the time you'll have no problem seeing what's happening on the screen.

Battery life

Xiaomi Redmi 3 has almost double the battery power of its predecessor - a 4,100 mAh battery is a serious battery for a 5" device.

Before we continue with the battery life test results, we want to announce a change in our battery testing routine. Starting with the Xiaomi Redmi 3, we will be testing all devices on a fixed level of brightness of 200nits instead of merely positioning the slider at 50%.

This change has been a popular user request for quite some time now. Whereas before we would set the brightness slider midway on the phone's brightness slider, which worked out to a relatively random brightness number, we would now aim for a fixed level.

The level of 200nits, which we've chosen for our tests, has become somewhat of an industry standard. But more importantly, it's both the median and average value of the brightness levels at which we've tested all reviewed devices so far. This means our older battery life results will remain relevant and comparable.

So, we ran our battery test, and the Xiaomi Redmi 3 scored a 107h rating, which means you can count on the battery to last 4 and a half days if you do an hour each of calling, web browsing and video playback a day.

Such usage pattern is of course entirely artificial, but we've established it, so our battery results are comparable across devices. You can input a usage pattern of your own over at our full battery test score table, where you can also compare it to all of the smartphones we've tested.



The Redmi 3 did well on all tests - 3G talk, web browsing, video playback, and it posted very impressive scores on standby, which makes it a remarkable performer. The Snapdragon 616 chip seems quite energy efficient, but we should mostly thank the 4,100mAh battery for that.

Our proprietary score also includes a standby battery draw test, which is not featured in our battery test scorecard but is calculated in the total endurance rating. Our battery testing procedure is described in detail in case you want to learn more about it.

Connectivity

The Xiaomi Redmi 3 supports 7 LTE bands, and you can tap to an LTE network on either SIM, but once you do, the second one will be limited to Global System for Mobile communication (GSM) connectivity only. As for that, the Redmi 3 also offers tri-band Global System for Mobile communication (GSM) connectivity. There is tri-band 3G connectivity with HSPA support.

The rest of the connectivity features include single-band Wireless Fidelity (Wi-Fi) b/g/n/ support and Wireless Fidelity (Wi-Fi) Direct. There is also support for Bluetooth 4.1, GPS with GLONASS and Beidou, 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 Universal Serial Bus (USB) hard drives.

Wireless classy screen mirroring is available via the Miracast protocol.

The IR blaster is located on the top and coupled with the correct software, it can be used to operate almost any remotely controlled home appliance, turning the Xiaomi Redmi 3 into a universal remote. Xiaomi provides its MiRemote app correct out of the box.
