To prolong my battery lifespan, is there any Android app that:
"will stop the charging & only kick in the battery charging when it
hits about 20-30% & then stop charging when it hits 80%?

What you want is a system level thing and only system app which is bundled with the Android OS can do it.

Currently, only ASUS and OnePlus can do it for Android OS while if you are using iOS 13 of an iPhone, you can have such feature too.

Ok, so if I'm on other phone brands, when the built-in
battery can't hold charge very well anymore (my spouse's
iPhone 6+ barely lasts 5 hours while on standby after the
phone was used for 2.5 years), the next options will be:
a) go to the workshop to have the built-in battery
    swapped
b) get one of those casings (eg: PowerBear): so these
    casings should not be obtained for new batteries as
    they'll charge the battery even if it drops by 1% &
    this dramatically increases the discharge+charge
    cycles of the built-in battery?
    I saw one ad for such battery case that claims it
    increases lifespan of built-in battery but I beg to
    differ.

Much appreciated any comment on item b above,
agree or disagree

One other question: this feature with ZenFone is available
even with the older Zenfone 2, 3, 4 or it has to be 5 & 6
(with newer Android versions) ?

It will not decrease or increase the lifespan of the internal battery. It just adds an extra power source when you cannot find one. Of course, you need to find and use one battery case which is MFi certified.
