What are the best tips for extending the life of a non-removable smartphone battery these days?

Question

Batteries

I bought a new Xiaomi Note 4x the other day and thought about how to make a shovel live for at least four years (I don’t care about declining performance, just to call), so much so that you need to charge no more than once every 24 hours (from 0% to 100 %).
Earlier, I remember, they said that you should always wait until the battery is completely empty before putting the phone on charge. And you need to charge it with a weak current, that is, for a long time. And keep the phone in the cold (I don’t know how).
What now? Are these tips still relevant? Or will the gain be negligible compared to the inconvenience of such approaches? What else can you do to save battery?
