Gigaset GX4 Review: The sustainable rugged smartphone

Sustainability bolide. Gigaset's GX4 is a robust rugged smartphone that brings along many forgotten virtues: An exchangeable battery, audio jack, and microSD support. But that is not all, Gigaset also provides a long update supply. There are some compromises to be made, however, which we detail in our review.

Case and features: Gigaset GX4 comes with IP68 and MIL-STD-810H ratings

The Gigaset GX4 is unmistakably a rugged smartphone, but it is less bulky than many other models from China. With IP68 certification, it is dust- and waterproof. The resistance according to MIL-STD-810H seems to primarily refer to the shock resistance, but Gigaset unfortunately does not provide exact details. The smartphone is not exactly light, but it still feels good in the hand. The build quality is convincing, and the material impression is also quite good. Corning Gorilla Glass 5 is used on the front.

The polycarbonate back is removable and allows access to the 5,000 mAh battery, which can be replaced without tools. The two SIM slots and the micro-SD card slot are also located under the cover. The slot is not one of the fastest and unfortunately does not support an exFAT file system.

Not only the small status LED on the front is practical, but the ring around the camera can also light up for incoming messages. Alternatively, it can also be used for the flashlight function.

Communication, software and operation: Two feature updates and five years of security patches

The Gigaset GX4 supports Wi-Fi 5, which is not the most modern and fastest standard, but it performs quite stably in the test with our reference Asus ROG Rapture GT-AXE11000 router. A big compromise in terms of mobile connectivity has to be made because the GX4 does not support 5G and the frequency band coverage is also just limited to the common bands in Europe.

The voice quality of the Gigaset phone is quite good when held to the ear, but great expectations should not be placed on the noise suppression. The speaker mode does not have a particularly long microphone range and the user sounds audibly hollow when using it.

Although Android 12 is not the latest version of Google's operating system, an update to Android 13 and Android 14 will follow in the future. Gigaset also promises a security patch supply of up to five years after market launch — exemplary.

The visually striking function key, which can be assigned up to three different tasks in the settings, seems practical. This includes starting a sound recording, taking a screenshot, controlling the flashlight, dialing the emergency call, or invoking any app. The power button is found on the opposite side, where the fingerprint sensor is also integrated. This usually works reliably. Alternatively, or additionally, facial recognition can be set up via the front-facing camera.

Cameras - 48 MPix without bells and whistles

Selfie with the GX4 (portrait mode)
Selfie with the GX4 (portrait mode)

The front-facing camera of the Gigaset GX4 offers a solid imaging performance, but likes to overdo it with the contrasts. Videos can be recorded in Full HD (30 FPS) at best.

The main camera takes decent pictures in sufficient light, only zoom shots are hardly usable. An additional ultra-wide-angle lens is available, which can also be used as a macro lens. The quality is satisfactory, but not overwhelming. At least a portrait, a night and a pro mode are available, the latter also allows saving RAW data.

Videos with the main camera are only recorded with 30 frames per second, usually in Full HD. If you need more resolution, you can also use the unusual QHD format.

Display: Bright 60 Hz IPS panel

Subpixel structure
Subpixel structure

The IPS panel of the Gigaset GX4 measures 6.1-inches and only offers the 720p HD resolution as well as a fixed refresh rate of 60 Hz. The brightness is identical both in a pure white display (645 cd/m²) as well as in the APL18 measurement. It also makes little difference whether the ambient light sensor is active, or the brightness is controlled manually. Thus, decent readability is ensured outdoors as long as it is not in the blazing sun.

The black value is slightly increased, but the contrasts remain appealingly crisp due to the good luminosity. The minimum brightness is also on a very good level. The color reproduction is very cool in all profiles, but this does not seem bothersome in everyday use.

The lack of pulse width modulation for brightness control is also positive.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
32.8 ms ... rise ↗ and fall ↘ combined↗ 11.67 ms rise
↘ 21.13 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 87 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.4 ms).
       Response Time 50% Grey to 80% Grey
70.38 ms ... rise ↗ and fall ↘ combined↗ 31.45 ms rise
↘ 38.93 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 98 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.5 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17673 (minimum: 5 - maximum: 3846000) Hz was measured.

Performance, emissions and battery life: Up to three days on a single charge

The Gigaset GX4 is powered by a MediaTek Helio G99 with 4 GB LPDDR4x working memory. Some added RAM would certainly have been better in view of the rugged smartphone's potentially long lifespan. However, the everyday performance is quite decent, and most apps run pleasantly smooth.

The surface temperatures remain low at all times. Even under constant load, the GX4 does not even get lukewarm. The SoC also has no problems with the generated heat and delivers a constant performance.

The mono speaker delivers a decent sound output, but is certainly not an entertainment performer. Media is better consumed via headphones. The most common audio codecs (SBC, AAC, aptX, aptX HD, LDAC) are supported wirelessly via Bluetooth, and a very low-noise audio jack is available via cable (signal-to-noise ratio: 90.41 dBFS).

The large 5,000 mAh battery battery helps the Gigaset GX4 to achieve long runtimes. In the test, the smartphone also proved to be very frugal in standby, so it should be possible to go three days without recharging in moderate use.

Verdict: Gigaset GX4 with strong core competencies

The Gigaset GX4 is a good and particularly rugged everyday companion. High-end features or 5G are not found here, but the rugged smartphone convinces with a conclusive overall concept. This is especially true for sustainability, since the outer packaging does not contain any plastic and is made of cardboard. In addition, there is a replaceable battery and a long update supply, which is usually not obligatory in this price range. In case of a defect, Gigaset has you covered with enough number of service centers, especially in Europe.

The Gigaset GX4 is a robust everyday companion with enormous endurance.

Compromises have to be made when it comes to the display as the GX4 is a bit old-fashioned in this aspect with a 720p resolution and 60 Hz refresh rate. In addition, it does not have DRM certification, so correspondingly protected content can only be consumed in standard definition. The exFAT file system for the optional mircoSD is also not supported.

Considering its price, the Gigaset GX4 offers a good overall package. If you want a bit more of everything, you should take a look at the Gigaset GX6 but will have to pay more. The situation is similar when it comes to the Samsung Galaxy XCover 6 Pro.

Price and availability

The Gigaset GX4 can be purchased directly from the Gigaset store, but is also available from most other retailers and Amazon.
