YMMV quite a bit depending on OS, usage, etc. I have a 6 yr old Thinkpad (which btw was gonna replace with a framework and didn’t). It’s plugged in 99% of time, so battery health is not a problem. I think it lasts 2 hours now. I’ve nodded the charging port to USB-C so I can keep it running on an external battery in rare occasions when I need to. It has 16GB of RAM which is still plenty on Linux and with the kind of apps I run and my dev setup. But when time comes that I need more, I’m gonna trade some CPU cycles and compress the memory and get maybe several more GBs out of it. SSD is infinitely upgradable as it’s a 2.5” drive, so is the WiFi and it also has a M2 slot which I can use for another SSD or a LTE modem. Linux support is perfect. With cheap cloud computing, I don’t think I’ll update the laptop for next several years.
