Google started a program back in 2014 to encourage other hardware vendors to build just such things. It is alas, now on hospice care, with death imminent:
Pure Android experience with no bloatware, 2 full days of battery with moderate usage, a decent screen, fast, confortable to use, and also was cheap.
Nowadays most Android phones have plenty of bloat and lack some specifications unless you spend some money. It's sad how a cheap phone that were usable was €150 to €200 and now the bracket is between €300 and €350.
