Legion Tab Gen 4: New Lenovo gaming tablet promises reliable battery life

The Lenovo Legion Y700 refresh is set to launch in China on May 8, 2025, and it's expected to be rebranded as the Legion Tab Gen 4 in the global market. Before the Chinese launch, the company confirmed most of the core highlights of this new gaming tablet, and now, it has showcased the reliable battery backup of the pad.

Per a recent teaser on Weibo, Lenovo shared that the Legion Tab Gen 4 can deliver up to 14.8 hours of video playback with a full charge. The company notes that this video playback battery life rating comes from a test carried out at the 1080p resolution with the volume set at level 7 and the screen brightness at 200 nits.

On that note, the screen of the new Legion pad saw an upgrade from its predecessor. It can reach a brightness level of 600 nits, a noticeable jump from the 500 nits display of the Legion Tab Gen 3. Lenovo has also recently confirmed that the screen of the upcoming Snapdragon 8 Elite gaming table has a higher resolution, at 3040x1904 pixels, another jump from the 2560x1660 pixels resolution of the last-gen device.

Returning the video playback battery life rating, Lenovo's last-gen Legion gaming tablet (curr. $489.99 on Lenovo) had an official 16.06 hours rating. However, Lenovo doesn't specify this test's playback resolution, brightness, and volume level. It's also worth noting that the Legion Tab Gen 4 has a more efficient SoC, the Snapdragon 8 Elite, and it has a higher battery capacity, from 6,550 mAh to 7,600 mAh.

So, it's possible the Legion Tab Gen 4 may outperform the last-gen gaming tab in a comparable video playback test. In related news, the company has teased a gaming handheld, which is possibly the same tablet that's slid into an accessory. More new details about the tab could be revealed in the coming days.
