The REDMAGIC Astra 2 is built for long gaming sessions, but its battery results are mixed. Its 8,300mAh cell is only 100mAh larger than the previous generation’s 8,200mAh battery, and its 14-hour, 15-minute video-playback result is respectable rather than class-leading.
In video playback testing, the Astra 2 finished behind the Lenovo Legion Tab 8.8 (2025), which lasted 16 hours and 54 minutes. The REDMAGIC tablet’s result is also close to the Samsung Galaxy Tab S6, at more than 14 hours and 20 minutes, and the Huawei MatePad Pro 13.2, which also exceeds 14 hours.
Better results under sustained use
The picture improves in a continuous-use test, where the Astra 2 ran for 7 hours and 30 minutes. That is notably ahead of the Lenovo Legion Tab 8.8 (2025), which recorded 5 hours and 49 minutes in the same type of workload. For a compact gaming tablet, that gap matters more than the video result: mixed, demanding use is closer to the way the device is likely to be used between charging sessions.
A quick recharge for gaming breaks
Charging is one of the Astra 2’s stronger points. Using 75W charging, the tablet went from 0% to 100% in 54 minutes, slightly faster than REDMAGIC’s own 57-minute claim for the USB 3.2 Gen 2 port. It reached 17% after five minutes, 43% after 15 minutes, and 76% after 30 minutes.
- 8,300mAh battery, up from 8,200mAh on the prior generation
- 75W wired charging with a measured 54-minute full charge
- Two side-mounted USB-C ports
- Bidirectional reverse charging for powering a phone or accessories
- Bypass charging, designed to power the tablet while avoiding battery heat during gaming
- Extreme Cold charging mode for sub-freezing ambient temperatures
The dual USB-C ports can also support bidirectional reverse charging, allowing the Astra 2 to act as a power bank for a phone or accessories when needed. Bypass charging is particularly relevant for plugged-in gaming, as it is intended to reduce heat by supplying power directly to the tablet instead of charging the battery. The Astra 2 does not lead its category in video endurance, but its faster recharge time and stronger continuous-use showing make it a more practical fit for gamers who can top up between sessions.
