Have you considered replacing the battery? I have a oneplus 3, haven't had security updates in a very long time, but no issues so far. Battery has become shit now after 7 years, but still works OK.
I hate that Google killed that project. Haken's block phone is still a great concept that is now used for Framework laptops. I hope thats someone can start doing that for mobiles. Fairphone is OK, but still far from Haken's idea.
