Chromebooks don't need a lot of power to reliably meet the demands of everyday use. A battery with 29 Wh is enough for the economical device to run for 12 hours. However, the stable Chromebook Duet 11 also shows surprising strengths in other areas.https://www.notebookcheck.net/Lenovo-Chromebook-Duet-11-test-Mobile-energy-saving-champion.949211.0.html
Thorough review, however I would've like additional review on the OS/Software and tablet/ laptop experience. This Chrometablet supports 3 OSes (Chrome, Linux, Android) and functions in windowing as well as tablet modes. I've had many devices off this class and wished they'd get rid of the back cover (nothing to protect) in favor of a kickstand that rotates and corner bumpers to protect the screen glass.
Good review, however it lacks meaningful comparisons with similar devices such as Duet 3 and OG Duet (or with other more powerful ARM-based Chromebooks, such as with Kompanio 1XXX series SoCs).
Additionally, the CPU is a 2x A78 and 6x A55, not 4+4.
I'm still waiting for the ARM Chromebook tablet with flagship-grade SoC. I still feels like there's more to extract from ChromeOS on ARM.
