I have an InfinityBook Pro 14 Gen 7, with the RTX 3050 Ti laptop, 2x2TB SSD, Intel i7-12700H and I believe also a 53 Wh battery (did not go for the battery edition with increased capacity, but instead the storage edition).
Even when using the integrated Intel GPU, the battery life is quite bad. With any kind of browser activity, I get about 2-2.5 hours. If I only do reading in Zotero with dark mode, I get up to 5 hours. For my use case, it is fine, but I could not have used this if I was dependent on working with no access to a power outlet.
Otherwise I am quite happy with Tuxedo though, and their support is usually very good. I hope they will succeed long term if they can also continue to improve on their products.
