Just replaced for the first time battery on my Macbook Pro 2015 Retina. Feel so good using such an old piece of hardware.

I love mine, it has a fresh battery OEM battery as well. Runs the latest OS with OpenCore Legacy. But it's starting to get a bit annoying. Usable, but it is starting to feel slowish, the fan kicks up frequently.

I might still keep it another year or so, which is a testament to how good it is and how relative little progress has happened in almost 10 years.

If it's got a full function row, it will probably work just fine under Linux. My 2014 MBP chugged pretty hard with OpenCore but handles modern Linux distros much better.

Same, the jump to the last few OS versions is not pleasant. Do you get good battery life on Linux with it?

If I still had my 2015 I would have applied some liquid metal TIM by now, I did a paste refresh and that worked very well to get the fan under control.

Did you disassemble the fan assembly? And applied new thermal paste?

I'm not using mine any more, but I noticed a big difference when I replaced the battery and got all the dust out this spring. Also installed a new battery. Still quite a hard sell on the used market :)

Which MacOS version? I upgraded to a newer one and it crawled to a halt, it's unusable now. UI is insanely laggy. It's sitting in a drawer gathering dust now

How long is your battery life? I've replaced the battery 2 times in my MBP 2015 (iFixit battery) but battery life is only 2.5 hours and I'm perplexed.
