TCL 20R 5G

TCL 20R 5G – a good honest 5G smartphone at $349 (review)


The TCL 20R 5G is a good, honest 5G phone that meets or exceeds our test paradigms. It is all you need – support for all Australian 4G, 5G sub-6Ghz and 5G Low bands; 13MP tri-camera; 4/64GB/microSD; hybrid dual sim; 4500mAh battery; 6.52″ screen; NFC; Wi-Fi AC/BT 5.1; and 3.5mm jack. Whew!

TCL is the latest player in the Australian smartphone market. It owns the Alcatel brand, and the product ranges have merged under the TCL banner. The 20-series (2021) ranges from (low-to-high) 20 SE 4G ($297), 20 5G ($499), 20L+ 4G ($398), 20 Pro 5G ($799) and 20R 5G ($349 – this review) and the specifications cover a broad range. So when you are reading reviews, make sure it is for the right one.

As TCL is a recent entrant to the smartphone market, retail outlets are scarce – generally Harvey Norman and Officeworks. We have noticed a small amount of grey market parallel imports. As it is a 5G device, it is critical to ensure it has the RCM C-Tick mark in Settings, System, Regulatory and Safety, or it won’t work here.

More about TCL Technology

TCL Technology (Wiki here – originally an abbreviation for Today China Lion) is a Chinese multinational electronics company headquartered in Huizhou, Guangdong Province. Founded as a state-owned enterprise, it is now on the Hong Kong Stock exchange. It designs and manufactures television sets, mobile phones, air conditioners, washing machines, refrigerators and small electrical appliances. TCL now means ‘The Creative Life’. It also owns the Alcatel brand.

First impression – The TCL 20R 5G is chunky

And that is not a bad thing. It is solid at 164.3 x 75 x 8.99mm x 186 – but not overly heavy. It has a reasonably big chin, a teardrop selfie notch, flat-screen, fingerprint reader (back), 3.5mm port and a tri-camera bump.

Solid and reassuring in hand, the front glass is a fingerprint magnet, and the rear panel is a matte finish.

Screen – perfect for the price

Size6.52”, 1600 x 720, 20:9, 268ppi, 60/90Hz, 16.7m colours
IPS with a top teardrop selfie

It is a visually pleasing, saturated colour screen with adjustment handled by TCL’s NXTVISION app. This offers automatic (depends on ambient light) image and video enhancement and a choice of vivid (default), Natural and Advanced (custom).

TCL claims 500 nits and 1200:1 contrast (theoretical peak) with no claim to sRGB or DCI-P3 gamut coverage. Real-life tests are <300 nits and 1000:1 – still, it is quite a good screen for the price.

The screen refresh is automatic or fixed at 60 or 90Hz (180Hz touch sample rate for gamers). All tests were on auto, which generally defaults to 60Hz except in TCL apps and the UI.

It will play Netflix in HD/SDR.

Processor – fine for the job

 Throttling is a given in any lower-cost device, and this is within a typical range. The raw power is 7% faster than an SD732G, but its overall AI power is about 20% lower. Overall, a suitable chip for the price.

The MediaTek Dimensity 700 is a 7nm chip, so it runs quite cool and is energy efficient. It is a very popular chip used in Motorola g50, realme 8/V3, vivo V21/Y72, Samsung A22, OPPO A53s/55 and dozens of other phones.

It is similar to most phones in this bracket.

MediaTek Dimenmsity 700 5G chips don’t have the signal strength for use outside the city or suburbs. If you need a phone for regional or rural use, it will cost more.

Battery – one day

Battery mAh4500mAh

GFX Bench Manhattan 3.1: 439.2 minutes, 7.32 hours, 2867 frames
GFX Bench T-Rex:  399.5 min  6.658 hours 4327 frames

Battery life is shorter than expected compared to other MediaTek Dimensity 700 smartphones. So we ran the tests three times with the same results. By comparison, the vivo Y52 and Moto g50  with the same processor get over double the PC Mark and GFX Bench battery life.

And it would not have killed TCL to supply a 15W charger either as 3 hours to charge is too long to wait.

Sound – mono

SpeakersMono earpiece and down-firing speaker. It is not fair to measure the sound signature of a mono speaker system. The primary use is for clear voice. It is not for music or movies with no bass or mid before 1000Hz and no treble after 10kHz. There is no sound stage.

Android 11 – but don’t expect OS updates at this price

AndroidGoogle Android 11
Security patch date 5/10/2021 (review 5/11)
UITCL UI v3.0.2B2A supplies alternatives to Google apps. It’s a relatively light touch over Android 11 bit does install some custom apps like browser, calculator, camera, files and more. If you are concerned about privacy, you can uninstall these and use Google Alternative. Given the limited storage space, we recommend you uninstall all unnecessary apps.
GoogleAll standard Google apps, Lens and Assistant.
BloatwareAmazon Shopping,, generic office suite, and Facebook that you can uninstall. You can’t uninstall Netflix.
Update PolicyNo OS upgrade but ‘regular’ security patches to August 2023
SecurityFingerprint sensor on the power button – reliable
Face ID – 5/10 because reliability depends on ambient light
TCL doesn’t appear to ask for any PII unless you opt to allow it at install time.


Nothing for the price. There is no point wishing for Qi charging, stereo speakers, AMOLED etc., as that is about double the price.

TCL 20R 5G – camera

The MediaTek Dimensity 700 supplies just enough AI for reasonable computational photography -certainly better than social media quality. But given that, you need to be a little more careful with low light. It only has one photo setting – auto and 1-4X zoom.

It is a tri-camera, but the 13MP does all the work with Macro for Macro only and depth for bokeh calculations. So you don’t have wide-angle or telephoto.

The camera is fine on day and office light-producing quality images. It cannot handle low light.

The Samsung sensor is suitable and has contrast autofocus, which is better than the generic sensors of this size.


The rear video takes 1080p@30fps. That is not a strain for any modern smartphone. In day and office light, the results are pleasing. But it struggles with lower light. The front video struggles with too much noise – drop back to 720p, and it is fine.

GadgetGuy’s take

TCL is a latecomer to the Australian smartphone scene. It is hard to get shelf space, let alone visibility at the major retailers. This is a shame as the TCL 20R 5G at $349 exceeds all reasonable expectations.

My only two concerns are battery life and 4/5G signal strength. On the battery life issue, it is about half that of similar MediaTek Dimensity 700 phones. A firmware update is needed to address that. On the signal strength – while it is typical of Dimensity 700 – it is strictly a city and suburbs phone with good transmission tower density.


Rating explanation

Our base pass mark is now 6/10 (was 8/10) to allow more headroom to reward excellence. For the older reviews above, take off one point for a better comparison.

TCL 20R 5G
The TCL 20R 5G is a good, honest 5G phone that meets or exceeds our test paradigms for a $399 phone. It is all you need
Value for money
Ease of use
Great value
Better than social media standard camera
All Australian 4G and 5G bands
Acceptable quality and features for the price
Battery life is shorty than expected and only 10W charger supplied
