Verdict - The RedMagic Astra packs a ton of power into a compact case
Performance is paramount when it comes to the Nubia RedMagic Astra. The tablet boasts high-quality features, including a Snapdragon processor, dual graphics chips, UFS 4.1 storage, and a sophisticated cooling system.
The bright OLED display and rich stereo speakers also impress when handling media consumption and gaming. A large battery ensures long battery life despite high power consumption.
Both the build quality and compact form factor are impressive. This makes the Astra attractive for demanding users seeking a compact device – not just gamers. An LTE version would be even more suitable for mobile gaming fun.

With the RedMagic Astra, Nubia is offering a 9-inch gaming tablet. In addition to its compact size, the device features an active cooler and RGB lighting on the rear.
The Astra is available in three configurations: 12 GB of RAM with 256 GB of storage, 16 GB of RAM with 512 GB of storage, and 24 GB of RAM with 1 TB of storage. However, the largest version is only available in black – called Eclipse. The white version – Starfrost – is only available in the two smaller versions.
Specifications
Case - The RedMagic has an aluminum case and RGB lighting
Nubia has opted to use an aluminum unibody for its RedMagic Astra. The Astra sits comfortably in your hand and has a solid feel. The rear camera doesn't protrude, and this means the device sits flat on a table without wobbling. The screen bezels are symmetrical and narrow.
A fingerprint reader is integrated into the power button. The Astra also has a red dedicated button in its frame that activates gaming mode by default. However, the button assignment can be customized. On the rear, the RedMagic logo and a ring next to the camera can be illuminated in RGB colors.
Features - The RedMagic Astra uses USB 3.2 Gen 2
Nubia relies on high-end components to enable the smoothest gaming experience possible. The Snapdragon 8 Elite is actively cooled to prevent excessive throttling. Nubia offers two fan modes, and the fan can also be turned off.
The manufacturer has omitted NFC, satellite connectivity, and a headphone jack. Despite the fan, the Astra is IP54 certified.
The USB-C port supports USB 3.2 Gen 2. We measured a transfer speed of 690.26 MB/s when paired with a Samsung PSSD T7. NTFS and exFAT are the supported file systems.
Software - Nubia offers 5-year updates in the EU
The Redmagic Astra runs Android 15 together with its own RedMagic OS 10. Some third-party apps are installed out of the box, but they can be easily uninstalled. Nubia promises five years of software support for EU devices. At the time of reviewing, this applies to security updates, and version updates are expected to be available every three years.
Special features include quick settings for the fan management and the lighting elements. There's also a gaming mode that suppresses notifications and improves performance.
Sustainability - Nubia keeps things under wraps
Nubia hasn't provided any information regarding the RedMagic Astra's carbon footprint. The packaging is largely plastic-free.
Communication - The Astra has WiFi 6 but lacks LTE
Nubia doesn't offer an LTE version of the Astra, but thanks to Wi-Fi 6E, the RedMagic tablet impressed us with high and stable transmission speeds when paired with our reference router, the Asus ROG Rapture GT-AXE11000. The Astra can't establish satellite connections.

Cameras - The RedMagic Astra is good for quick snapshots
The Nubia RedMagic Astra has only one camera on the front and one on the rear. The manufacturer advertizes the smallest camera on the front. Image quality is decent, especially for quick snapshots, and the color balance is very bright.
The images lack detail, and in low light, there is noticeable image noise, and this noise is also noticeable in videos. The main camera's video stabilization works well, but zooms in significantly. The main camera can record in 4K, while the front camera can record at a maximum of 1080p, but the fps cannot be adjusted.
Accesories and warranty - The Nubia gamepad is included
The RedMagic Astra's box contents are very straightforward. Besides the tablet, it only contains a USB cable. The manufacturer's accessories include a screen protector, a folio case, and an 80-watt power adapter. Nubia also offers a gamepad that, while not designed for the Astra, is compatible with it.
Nubia's RedMagic Astra comes with a 24-month warranty in Germany.
Input devices and operation - The Astra has a 2,000 Hz sampling rate
Out of the box, the RedMagic Astra comes with Google's Gboard keyboard. Typing is mostly flawless; however, due to the narrow bezels, fingers sometimes accidentally rest on the display, blocking input. Apart from that, inputs are very fast and can be received across the entire display area. Nubia promises sampling rates of up to 2,000 Hz.
Unlocking is possible via the fingerprint reader in the power button or 2D facial recognition. Both worked quickly and reliably in our tests. Nubia has installed two linear vibration motors in its RedMagic Astra, and the vibration is strong and crisp.
Display - Nubia has installed a fast, bright OLED
The RedMagic Astra features a 9-inch OLED display with a 16:10 aspect ratio and a maximum refresh rate of 165 Hz. The software independently regulates the refresh rate, but it can also be fixed to 60 or 165 Hz. According to DRM information, further settings of 90, 122, and 144 Hz are possible.
We did not achieve the 1,600 cd/m² promised by Nubia in our tests. Even with APL18 and HDR content, we measured a maximum of 1,048 and 1,049 nits with the ambient light sensor enabled. Without the sensor, a maximum of 647 cd/m² was possible.
In everyday use, the device's brightness is sufficient for easy viewing, even outdoors. Comparable devices only achieve about half the brightness. We measured screen flickering at a frequency of 120 Hz in our test.

The display backlight flickers at 120 Hz (worst case, e.g., utilizing PWM) . The frequency of 120 Hz is very low, so the flickering may cause eyestrain and headaches after extended use. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8320 (minimum: 5 - maximum: 343500) Hz was measured. | |||
A series of measurements with a fixed level of zoom and different brightness settings (The amplitude curve at minimum brightness appears flat, but this is due to the scaling. The enlarged version of the amplitude at minimum brightness can be seen in the info box.)
The Astra panel's tuning is excellent, and color deviations are largely imperceptible. According to Calman 2D measurements, the RGB color space coverage is 95.3 percent.

Thanks to its high brightness, the RedMagic Astra is even easy to read outdoors. Viewing angles are also good, allowing content to be reliably read from sharp angles.
Performance - The Astra has a top SoC and fast storage
The Nubia RedMagic Astra benefits from the very performant Snapdragon 8 Elite. Thanks to the active fan, performance doesn't have to be throttled as quickly as with other devices, and this is reflected in very good benchmark results.
The high system speed also benefits from the fast UFS 4.1 storage. Overall, the RedMagic Astra flies through applications. The browser benchmarks show significant differences between various browsers. With Chrome and Edge, the Astra falls significantly behind the comparison devices. With the ZTE browser, however, the Astra comes in well in front.

Emissions - The RedMagic Astra gets hot and loud
Temperature - Over 50 degrees in the extreme test
Nubia touts various cooling components designed to ensure the RedMagic Astra doesn't overheat even when under load. The manufacturer uses a 13-layer system with multiple cooling chambers and an active fan.
Nevertheless, the tablet's rear side reached a maximum of 52.6 degrees Celsius in the Burnout benchmark. This makes it very hot, especially in the center of the device, which is not held during use. This is unnoticeable in everyday use or while gaming. The Astra is comfortable to hold even while gaming, and despite the sophisticated cooling system, the Astra throttled during stress tests.
(-) The maximum temperature on the upper side is 51.9 °C / 125 F, compared to the average of 33.7 °C / 93 F, ranging from 20.7 to 53.2 °C for the class Tablet.
(-) The bottom heats up to a maximum of 52.6 °C / 127 F, compared to the average of 33.2 °C / 92 F
(+) In idle usage, the average temperature for the upper side is 29.3 °C / 85 F, compared to the device average of 30 °C / 86 F.

Speakers - The Nubia offers powerful stereo sound
Nubia has installed stereo speakers in its Astra, which are located on the short sides of the frame. The Astra's sound is rich and balanced, and the speakers aren't obscured when held. On top of this, the tablet gets pleasingly loud.
At maximum volume, there's a slight vibration on the rear side.

Battery life - Big battery meets high consumption
Power consumption - The RedMagic Astra is power hungry
Compared to its competitors, the RedMagic Astra consumes a lot of power, both in idle mode and under load. It also consumes a lot of power compared to other Snapdragon 8 Elite devices.

Battery runtimes - The Astra keeps going for 12 hours
The high energy demands are matched by a large battery, which has a capacity of 8,200 mAh. This enabled the RedMagic Astra to achieve a runtime of over 12 hours in our realistic Wi-Fi web surfing test. We don't have a Nubia power adapter, but instead use an Anker 335 power adapter. This allows the Astra to charge from 1 to 96 percent in 60 minutes.
The tablet can be optionally cooled by a fan while charging, and it can also be operated from the mains without charging.

Notebookcheck overall rating
The Nubia RedMagic Astra focuses on performance in every area. It flies through every application and is a real pleasure to use. The bright display and stereo speakers are also impressive. The Wi-Fi connection, the built-in storage, and the USB-C port are just as fast.
