Verdict on the Motorola Signature
The Motorola Signature is a very strong flagship smartphone, although it is not convincing in every area. The slim yet highly durable body, the very bright AMOLED screen, and the camera setup with its four 50 MP lenses are definitely first class. Combined with the 7-year update guarantee, you should be able to enjoy the Signature phone for a long time.
However, the Snapdragon 8 Gen 5 in Motorola's top model is not the most powerful SoC, and anyone who frequently uses the smartphone for gaming will likely be disappointed with the test device due to high heat generation. The battery also lags behind the competition. Although the noise levels are good, they are slightly below average by high-end standards.
Pros
Cons
Price and availability
The Motorola Signature costs just under 1000 euros from Lenovo. At the time of testing, you can get it for just under 950 euros on Amazon, for example.

Motorola has named its new flagship smartphone Signature and is positioning it against the top models from Apple, Samsung, and Xiaomi. It should be particularly impressive in terms of the camera and has already received praise in this regard. In the DxO benchmark, it beat top smartphones such as the Google Pixel 10 Pro, putting it in the top 10 smartphones with the best cameras at the time of testing.
Specifications
Case - Top of the league both visually and haptically
Available in the Pantone colors Martini Olive (yellow-green) and Carbon (navy blue), the Motorola Signature features a curved design with an aluminum frame. The back cover finish of the olive model resembles cotton twill. The navy blue version has a linen-like texture.
At 186 grams, the Motorola Signature is lighter than many other top smartphones and measures just under 12 millimetres at its thickest point. It is protected against dust and water in accordance with IP68/69 and meets military robustness requirements under MIL-STD-810H standard. Gorilla Glass Victus 2 is used for the display glass.
Features - Motorola Signature with 16 GB RAM and 512 GB storage
Regardless of the color variant, 16 GB LPDDR5X RAM and 512 GB UFS 4.1 memory are on board. There is also WiFi 7, Bluetooth 6.0, dual SIM, a USB-C port with USB 3.2 Gen.1 and stereo speakers.
Software - Android 16 and updates until 2033
Motorola equips the Signature with Android 16 and leaves the Google OS virtually untouched. In addition to Moto AI, only a handful of third-party apps are installed, but these can be deleted. Motorola promises 7 years of updates.
Sustainability
The Motorola Signature comes in plastic-free packaging. It is printed with soy ink and is made from recycled materials in accordance with the FSC Mix certification. There is a lot to read about sustainability on Motorola's website. However, the manufacturer does not provide any information on the Signature's carbon footprint.
Spare parts and instructions for self-repair are available from Motorola's partner Replacebase. If you buy the Signature via the Motorola website, you can trade in a smartphone that you no longer need.
Communication and GNSS - WiFi 7 and WLAN speeds up to 1500 MBit/s
Thanks to its wide selection of LTE and 5G bands, the Motorola Signature should be able to receive a signal in practically any location.
Thanks to WiFi 7 support, the Motorola Signature can use the 6 GHz band on our Asus ROG Rapture GT-AXE11000 reference router and achieves quite stable transmission rates, which peak at around 1500 Mbps.

The Motorola Signature uses GPS, Glonass, and Galileo to determine its position well, but not quite as precisely as you would expect from a top smartphone.
The accuracy is sufficient for everyday use. In a direct comparison with the Garmin Venu 2 fitness smartwatch, however, the Motorola phone was slightly inaccurate in a few sections of our test round and sometimes built an imaginary loop.






Phone functions and voice quality
The Motorola Signature supports dual-SIM operation with nano-SIM and eSIM, and also offers VoLTE and Wi-Fi calling. In the test, the smartphone delivered good voice quality and reproduced voices clearly and distinctly.
Camera - Four times 50 megapixels and Sony LYTIA image sensors

Motorola has equipped the Signature with four 50 MP lenses. There is one each in the main, ultra-wide-angle, and telephoto cameras, while number four serves as a selfie camera and does a good job of it.
Equipped with Sony LYTIA sensors, the quartet of cameras produces very good images in daylight that have excellent dynamic range, show a lot of detail, and reproduce colors very realistically. The main camera benefits from its large 1/1.28-inch sensor, which allows the Signature to take very nice pictures even at night.
The image quality also remains high with the ultra-wide-angle and telephoto cameras, although the former struggles with slight blurring at the edges of the image. The telephoto camera offers an optical 3x zoom and can digitally enlarge images by up to 100x, which then looks very artificial. Very good results can still be achieved at medium zoom levels up to around 5x.
The Motorola Signature records videos in very good quality with up to 8K at 24 frames per second. At 4K, 60 frames per second are possible.

Main cameraMain cameraUltra wide-angleLow light

Accessories and warranty - Protective cover included
The Motorola Signature comes with a USB-C cable, a protective cover, a SIM tool and a quick start guide.
Motorola offers a 24-month Warranty on the Signature.
Input devices and operation - Responsive display and AI button
The touchscreen is scanned up to 360 times per second. At the same time, it displays up to 165 Hz, resulting in very fast and precise operation. This also applies to the fingerprint sensor under the display.
Pressing the left button on the housing activates Moto AI. The button can also be deactivated, but cannot be assigned other functions.
Display - Reaches luminosities of up to 4500 nits

You can expect a lot from the display, because according to the specification, it should shine at up to 6200 nits. We did not achieve this in our measurements, but with up to 4500 nits in HDR, the screen still delivers a very high level of brightness. It also displays content very sharply.
For PWM-sensitive users, there is a Prevent Flicker switch in the display settings, which then uses DC-like dimming that works at 120 Hz in all brightness levels.

Performance - Motorola Signature with Snapdragon 8 Gen 5
In the Motorola Signature, the Snapdragon 8 Gen 5. This does not give you absolute top performance, but performance within sight of the high-end range. A MediaTek Dimensity 9500 or a Snapdragon 8 Elite Gen 5 develops significantly more performance. The UFS 4.1 memory keeps loading times short with its excellent data throughput.

The duet of Snapdragon 8 Gen 5 and the Adreno 826 is responsible for the graphics calculations. With 42 frames per second in the GFXBench 4K Aztec Ruins benchmarks, the GPU proves that it can also run very graphically complex games smoothly. However, as in the CPU tests, it is not enough for a top spot here either.

Speaker
The Motorola Signature supports Dolby Atmos and Hi-Res audio. It delivers the best sound when external audio devices such as headphones are connected via USB-C or Bluetooth. In contrast, the stereo loudspeakers are clearly inferior in sound quality but still perform quite well given their limited capabilities.

Battery life
A long battery life is guaranteed with the Motorola smartphone, but on the other hand, it does not reach new peak regions. In our WLAN test, it managed just under 20 hours. The Apple iPhone 17 Pro Max and the Samsung Galaxy S25 Ultra last significantly longer.
Notebookcheck overall rating
The Motorola Signature scores with many advantages, including excellent cameras, a bright display, 7 years of updates, and a very slim and lightweight body. However, other flagship smartphones offer more in terms of battery life and processor performance.
