Quote from: Y_xa on December 07, 2025, 11:55:21I have Thinkpad X395, which is practically 6 years old version of this. What I can not understand is that how is in simple websurfing, this 6 years newer laptop has only 13% better battery life?

In 6 years may be the testing has changed and the 13% is incorrect? Just a guess, or it's really that bad of an improvement.

This is indeed a big minus. To quote from a different post: .com/index.php?topic=215207.msg694078#msg694078:

QuoteWith only up to 32 GB RAM option and soldered at that, this laptop will age like milk. And the 8533 MT/s won't help at all. 32 GB minus 8 GB for the OS+etc. leaves 24 GB RAM and this is not enough to self-host the actually usable LLMs out there, even at the maximum usable quant (typically Q4_K_M). 48 GB or 64 GB RAM options required. (and ideally +~10 GB more for things like Gpt-Oss-120B)

I can understand underload, as cpu and gpu are much stronger and you actually do have much better performance. But in web surfing? They should optimise it so that in simple tasks, 6 generations newer laptop should be able to have at least 50% better battery life or so.

Interestingly, it's not for sale anymore at Lenovo USA.

The input lag of 60 Hz is annoying. Time to make 90 Hz the minimum.

Even Steam users will soon have 32 GB RAM as the majority (see monthly Steam hardware survey). For hosting the better ones local LLMs, 32 GB RAM is not enough, offer an option for at least 48 GB, or 64 GB RAM.

Pretty nice machine overall, but the 255H variant is both cheaper and faster.

Thinkpad with mediocre keyboard 😮
