In addition to the comprehensive IP68 standard, the Gigaset GX6 is also certified with MIL-STD-810H. This certifies that the smartphone can be used under extreme conditions. The Mediatek Dimension 900 processor with 2,400 MHz ensures a performance suitable for everyday use. With graphically demanding content, however, you have to step back. The GX6 has everything you need in terms of equipment: The 128 GB of internal memory can be expanded using an SD card, and there is also a Type-C USB 3.0 port. The dual SIM slot accepts two 5G SIM cards.
The Gigaset GX6’s LCD panel does a good job, but it’s far from high-end. The sharpness is good at 403 ppi, and a refresh rate of 120 Hertz ensures smooth scrolling. Unfortunately, the maximum brightness of 445 candelas per square meter is only moderate. The extended DCI-P3 color space is not optimally covered at 98 percent. The dual camera with optical image stabilizer offers decent images: the image quality is good even in poor lighting conditions.
The GX6’s 5,000 mAh battery has a strong runtime of 15:30 hours. If that’s still not enough, you can replace the battery. With a quick-charging power supply, the battery is charged to 50 percent after 30 minutes, but it takes almost two hours to fully charge it.
Our conclusion at the time of testing:
“The Gigaset GX6 manages to hide its robust outdoor skills under a chic exterior. The high-end smartphone impresses in the test with solid performance and extensive equipment including IP68 certification, freely assignable buttons and inductive charging. The is particularly commendable replaceable battery. The 120 Hertz display with LCD technology is denied a modern OLED panel. With the camera, including optical image stabilizer, you can take really decent pictures.”
