I'm gonna have to buy a new smartphone soon, but I want to be able to keep that as long as possible. From my viewpoint, there are mainly three aspects to that: performance, software and battery lifespan/replaceability.
Do you have any recommendations (what I was originally hoping for - but didn't find - is a mid to high range phone with a maintained lineageos build and a replaceable battery)? And what are your ways to handle the problem of the user experience on smartphones degrading so quickly?

For me, I have a huge collection of bookmarks in Firefox that are super unorganized. I have some semblance of folder system but...it's quite messy. I'm sure many people have a similar problem. Share your ideas on how you keep your bookmarks organized, what's your system?
