Oh yes, and when support ends it's practically impossible to use a phone.

I've never understood people talking about "support", still rocking a 7 year old phone (have changed the battery) with fairly recent lineageos. Only really use floss apps though and don't browse weird sites.

I use a computer for serious stuff.

If you really cared about waste you could a) not buy a phone with limited support if for some mystical reason you care for that or b) find ways to use the phone without support.
