Test Smartphone Huawei P20 Lite: the photo always recessed


Lancé at €369, the Huawei P20 Lite will cross the path of competitors such as theHTC U11 Life, theSony Xperia XA2 or the Samsung Galaxy A8 (2018). The latter will probably be one of the most difficult opponents for the P20 Lite, especially since many dealers have pushed its price under the €400 mark.

Ergonomics and design

Cela will not have escaped anyone's notice, the notches are invading the screens of smartphones. Made famous by Apple's iPhone X, this peninsula in a sea of pixels is far from unanimous. That hasn't stopped Huawei from adopting it for its P20 and P20 Lite. A choice on which one can wonder, insofar as the P20 Lite has a border below the screen. Nevertheless, the display occupies more than 80% of the front panel, making this smartphone a good example of a good student in the field.


Annotch, it's in fashion !

À In the back, we find a more classic design, with a glass slab that retains fingerprints. All in all, elegance remains the order of the day for this P20 Lite and the finishes are flawless. The lock and volume keys are well positioned to be operated with the thumb of the right hand.


Miroir, my beautiful mirror, tell me: who keeps the most beautiful fingerprints?

fingerprint reader is placed on the back of the smartphone. It is well positioned to fall under the index finger, but remains unusable if the terminal is placed on a table or hung on a stand in the car, for example. It works very well and the device unlocks almost instantly when a finger is placed on it. Huawei is also renewing its tactile capabilities, in particular to scroll through photos or to lower the finger-slide notification panel.


By the USB-C and a 3.5 mm jack plug.

Huawei P20 Lite does not offer waterproof certification, where a Samsung Galaxy A8 is rated IP68. Good news is that the P20 Lite has a microSD port - shared with the second nano SIM slot -, a USB-C port and a 3.5 mm jack.

Si Huawei adopts a new screen format with 19:9, the company is not abandoning LCD. Here, the 5.84" (14.8 cm) IPS panel displays a resolution of 2,280 x 1,080 px and a resolution of 434 dpi. This is no problem at all. With a contrast ratio of 1,600:1, the screen of the P20 Lite is among the good students in IPS. There is still one notch behind a Galaxy A8 and its Super Amoled panel. The P20 Lite also does rather well in sunlight, with a maximum brightness of 500 cd/m² and a light reflection rate of 15%.

Comme almost every time, you have to go through the display settings to get the best colorimetric rendering. Here, it is necessary to choose the "Warm" profile. One then notes a very good delta E at 2.9, even if one notes a less fidelity in the red, green and yellow tones. On the other hand, the temperature of the colors remains rather high, at 8 184 K, letting appear a bluish drift in the gray tones.

Côté reactivity, the P20 Lite is in the average of our comparison. We noted a tactile delay of 71 ms and a remanence time of 17 ms.


Huawei P20 Lite is equipped with an 8-core ARM Cortex-A53 Kirin 659 SoC and 4GB of RAM and has no need to be ashamed of the performance it delivers. The P20 Lite can cope with the vast majority of applications without slowing down. Only very demanding tasks may require a little more time than on a high-end smartphone.


Températures found during the CPU + iGPU solicitation.

Quand it is heavily stressed, the P20 Lite rises slightly in temperature on the surface, but without ever hindering the grip. The maximum temperature rise is 36 °C, and only in a limited area of the device.

La graphic chip Mali-T830 MP2 is a little weaker. It can still make most of the games in the Play Store run smoothly, but you should avoid very greedy games, which will have difficulty maintaining this fluidity, even if you lower the level of graphics.


L'audio is not particularly a strong point of this P20 Lite. Its headphone output is not the most powerful, but it will fit most nomadic headphones, and distortion remains at a low level. The dynamic range is slightly below the average of our comparison, while the stereo image rendering is just above. So the P20 Lite is not a big hit, but it looks good.

Avec only one speaker placed on the lower edge, you couldn't dream of high quality sound. Indeed, this speaker produces a relatively powerful but very inaccurate sound. Distortion becomes a problem beyond 75% of the maximum listening volume. It won't be used to watch an episode of a series, let alone to listen to music.


In photo, the Huawei P20 Lite is supported on the back by two modules. The first one integrates a 16 Mpx sensor and 26 mm equivalent optics (f/2.2), the second one relies on a sensor of only 2 Mpx and has no other purpose than to help the first one in the creation of "portrait" type photos, with a simulated background blur. In broad daylight, the shots are correct, but nothing more. We feel that the sensation of details in the image is artificially created by accentuating the contrast. We do not necessarily find the level of detail expected from a 16MP sensor. The exposure is satisfactory, but the white balance is a bit cold. In terms of responsiveness, the capture time is sometimes limited by a hesitant autofocus.

In low light, the P20 Lite remains fairly average. It manages to recover very little light and electronic noise is very present. It must be said that the smartphone captures its photos at ISO 3,200, a value that is rarely satisfactory, even on some SLR cameras. The sensor is not helped by the optics which only opens at f/2.2 and is not stabilized. Without being transcendental, Samsung's approach on theGalaxy A8 (2018) allows to recover more light and to offer a better exposed overall scene. On the other hand, you can't find more details on the pictures of the A8.

In video, the P20 Lite can edit up to Full HD definition (1920 x 1080 px). Unsurprisingly, Huawei's smartphone is more comfortable when there's enough light. Focus tracking is pretty good, as is exposure metering.

front sensor also climbs to 16 Mpx. It offers very detailed shots, above what is found on average on smartphones. There is a tendency to overexpose the backgrounds, but nothing too bad.


An3,000 mAh battery and a mid-range SoC are often the secrets of smartphones with very solid autonomy. The P20 Lite doesn't quite live up to this adage, but is still a serious student. On our SmartViser test protocol, the P20 Lite runs for 13 hours 58. An honest score, but not as good as a Samsung Galaxy A8 (2018) with 16 hours 48, or an Xperia XA2 with 15 hours 40. In practice, the P20 Lite can come close to two days of use in standard use, but will be more often in energy demand when it attacks the morning of the second day.
