I haven't noticed any of that for years, although phones before maybe 2018 or so definitely had some horrific lag(Think low end PC from 2014 with no SSD and 10 crapwares running at once level bad) at times, although they mostly stayed usable. I do see very occasionally delays when turning on from sleep, but I also have way too many apps installed and my phone is a year past support. In practice Androids are also used well past the update period, until either it physically breaks, or you hear of a CVE that bothers you more than the cost of a new phone would.
