Verdict on the Gigaset GS6 Pro
For those who place a high priority on maximizing value creation in Europe when buying a smartphone, Gigaset’s flagship is an interesting alternative to the Fairphone 6. The option to use the GS6 Pro with the Google-free AphyOS could also be a genuine reason to buy for some users. Otherwise, Gigaset promises seven years of Android updates. However, the long-term security patches are accompanied by only two major Android upgrades, taking the phone up to Android 17. The outdated software version during our testing—Android 15 with security patches from May 2026—also does not quite fit the GS6 Pro’s concept.
However, the regional focus of Gigaset’s flagship has its limits when it comes to the individual system components. As with the Fairphone, the hardware used in the Gigaset phone does not come exclusively from Germany or Europe.
The GS6 Pro’s German development and production come with a number of compromises compared with mid-range models from Xiaomi or Samsung. Its cameras, for example, are not competitive, and the chipset is anything but fast, resulting in recurring stutters in everyday use. The vibration motor also feels rather low-quality in daily use.
However, the combination of a replaceable battery, wireless charging, and a waterproof chassis is a genuine unique selling point in the mid-range segment.

Specifications of the Gigaset GS6 Pro
Case and features - Waterproof Android phone with microSD support
Gigaset’s mid-range phone offers IP68-rated dust and water resistance and a very good Class A repairability rating in the EPREL database. The GS6 Pro’s replaceable battery contributes positively to this rating. Despite being removable, the back cover is made of glass and feels quite high-quality. The frame, however, is made of plastic.
The build quality is good, but the screen-to-body ratio could be better. At around 86%, it does not quite reach top-tier levels. At nearly 230 g, the GS6 Pro is also noticeably heavier than the competition, while its thickness of more than 1 cm is another drawback in everyday use.
The GS6 Pro features a dedicated action button that can be assigned various functions, as well as microSD support. This allows the UFS 2.2 storage to be expanded relatively inexpensively by up to 1 TB. Less impressive is the slow USB 2.0 port.

Communication and usability - Android phone with 5G, but without Wi-Fi 7
The Wi-Fi module supports Wi-Fi 6E, including the 6 GHz band, although the results in our measurements were relatively low. For mobile data, the Gigaset smartphone supports up to 5G. However, the number of supported frequency bands is limited, particularly for LTE. Dual-SIM operation and eSIM support are available, though.
The optical fingerprint sensor works well, but unlocking the screen takes quite a while. The ERM vibration motor is also unconvincing and feels somewhat cheap.

Cameras - Affordable mid-range smartphone with a 64-megapixel camera, but without OIS
The GS6 Pro is not particularly versatile when it comes to its camera setup. Both the ultra-wide-angle and macro cameras are only of limited use in everyday situations. Photos taken with the 64-MP main camera, which lacks optical image stabilization, are reasonably sharp in good lighting conditions. However, upon closer inspection, fine details are barely discernible and textures look extremely artificial.
Due to the presumably rather small image sensor, low-light photos are anything but good and are not competitive for a 2026 mid-range smartphone. What impresses us most is the color accuracy of the GS6 Pro’s main camera.

Display - Large 120 Hz OLED screen without DC dimming
Despite its AMOLED panel, display enthusiasts are unlikely to be satisfied with the Gigaset flagship. In our measurements using the Calman analysis software, the 120 Hz panel showed very high color deviations. In our brightness test, we measured a respectable 922 cd/m², but significantly higher brightness levels are now common in this price range.
We detected screen flickering (PWM) on the GS6 Pro, although its base frequency of 485 Hz is relatively high. Unfortunately, neither high-frequency PWM dimming nor DC dimming is supported.

| Screen flickering / PWM detected | 485 Hz Amplitude: 17.65 % |  | |
The display backlight flickers at 485 Hz (worst case, e.g., utilizing PWM) . The frequency of 485 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 7686 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Performance, emissions, and battery life - An Android phone with a weak chipset but a replaceable battery
A major drawback of the Gigaset phone is its Dimensity 7300 paired with Mali-G57 MP2, a combination that is no longer particularly competitive in the mid-range segment in 2026. In our benchmarks, competing devices in this price range are sometimes more than twice as fast. The performance gap is even greater in the GPU benchmarks.
Given the underpowered hardware, we would at least have expected strong battery life from the Gigaset phone. However, at 16 hours in our test, the battery life is only average. In addition to 30-watt fast charging, the GS6 Pro at least supports wireless charging.
