Case, equipment and operation
The Neffos X20 is available in the colours Aurora Purple, Black, Red and Blue and fits well in the hand. The quality of workmanship and choice of materials is on a good level, our red test device also looks good, although the back is quite susceptible to fingerprints. The battery is firmly installed, there is no IP certification.
The Micro-USB port now looks a bit old-fashioned, but supports USB-OTG. A memory expansion using a microSD card is possible, but the exFAT file system is not supported. After all, a full dual SIM solution is offered. There is also an audio jack and an analogue radio receiver.
The software used is Google Android 9.0 Pie, whose security updates are as of April 5, 2019 at the time of testing and are therefore no longer up-to-date. Regular updates are certainly not the case here.
At best, the Neffos X20 gets into the mobile Internet with LTE, the frequency coverage is limited to the regionally common bands. The reception was inconspicuous in the test and the Neffos delivers a decent call quality in everyday life. It also supports VoLTE, but no WLAN calling. The WLAN is very fast and stable in view of the price class.
The operation as such gives no cause for criticism, only by the weak SoC short waiting times arise again and again. The fingerprint sensor on the SoC recognizes our finger very reliably in the test. Face recognition is also offered, which is a bit faster, but also less secure.

Cameras - Dual camera in the Neffos X20
The Neffos X20's dual camera offers neither an ultra wide angle nor a telephoto zoom, the second lens only collects depth information for Bokeh mode. The quality is good, but compared to top models it shows weaknesses in dynamic range and tends to be overexposed in bright image areas. The shutter release delay is also quite slow and the start of the camera takes almost two seconds.
Display - Neffos with low-contrast panel
The Neffos X20's 6.26 inch (15.90 cm, 97.81 cm²) display turns out to be a solid panel with sufficient brightness. Only in the APL50 test (347 cd/m²) does it weaken a little, which underlines the impression of the somewhat too weak contrast (APL50: 667:1) in everyday life. Positive: the supposed PWM is rather a high-frequency flicker, so no problems are to be expected.
The color reproduction shows visible deviations, but no falsifications and is on a level usual in the class.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 17860 Hz | ≤ 100 % brightness setting |  |
The display backlight flickers at 17860 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 17860 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17507 (minimum: 5 - maximum: 2500000) Hz was measured. | |||
Performance, emissions and battery life
The TP-Link Neffos X20 is driven by a MediaTek Helio A22, which is located at the lowest end of the performance spectrum. This is not only noticeable in the benchmarks, but also in everyday life, because small pauses for thought are the rule, there is no room for elaborate 3D games.
The surface temperatures are almost identical in idle as well as under load and always remain pleasantly low.
The loudspeaker of the X20 at the lower edge delivers a solid sound output, which completely misses the low mids, but delivers a good sound image at medium volume. If you turn up the phone fully, you'll only get a distorted sound delivered to your ear. Alternatively, an audio jack or Bluetooth 5.0 is available. The latter even supports aptX and aptX HD.
The battery life is on a good level with over eleven hours in the practical WLAN test, even though the Neffos smartphone is the last in the comparison field. We positively noticed the low consumption values in standby in the test. Even after more than a week without use, the battery was still over 60 percent full.

Pros
Cons
Verdict - Long runtimes and good audio properties
The TP-Link-Neffos X20 is a solid entry-level smartphone with a stylish look and good battery life. It also features an audio jack, analogue radio reception and even Bluetooth 5.0 with aptX HD. The latter is certainly a rarity in this price range. Just as positive, if you want to use Dual-SIM (2x Nano), you don't have to do without a microSD card.
The camera delivers rather moderate results, which are sufficient for simple social media needs, but quickly reaches its limits in low light. However, it offers many setting options and shooting modes.
The Neffos X20 is a colourful beginner's smartphone that convinces above all with its battery life.
Although the display is pleasantly large, it delivers a weak contrast ratio in everyday life. Outside, the panel is quickly overwhelmed. The system performance is quite slow, but this is no different for most competitors in this price range.
The smartphone is particularly suitable for occasional users who prefer to use their mobile phone for writing messages and otherwise leave it lying around more often. Especially the latter will be pleased that the battery only empties very slowly, especially in standby mode.
