I bought a Framework 13 in 2021. I was so stoked. I used it for 5 years, and of those 5 years only 1 was heavy use. I had to replace the battery and the input cover. I never had to do that before. I never had a laptop I wasn't able to use for 5 years so the repairability was actually not that much better for me. I gave up on Framework because after 5 years they still didn't give a crap about terrible battery performance on Linux distros.
I was using a Macbook Pro before. Went back to a Macbook Pro again. I don't want a Mac. I just can't find anything else remotely worth my money.
From reading online, linux battery seems to be a-lot better on the new intel board, and also if you configure linux with sleep to hibernate, you get really good behavioral performance. My experience is that the sleep states really drain the battery since the low power mode is not _that_ low power, at least with the ram I have.
For context I have a 13th gen intel with the old battery and only get ~4hrs of battery life, but generally go a week or 2 between full shutdowns, since I hibernate all the time. I can close the lid, throw it in my backpack, not use it for the weekend, and when I open it it is ready to go, not having lost charge.
I generally have a better experience than when I was on windows.
