In my experience, the best battery care measure is to get a phone with a good battery...

I bought a Huawei P30 Pro in early 2019, never took care of preserving the battery, always used fast charging (which is very fast in that phone, 40 W). 4 years later, the battery is still going strong (now the phone belongs to my wife).

On the other hand, I bought a Pixel 6 Pro in early 2021. From the beginning, I saw that the battery barely lasted a day of heavy usage, so I was more careful (trying to never get below 20%, deactivating 5G, etc.), plus the phone charges slower (around 20 W, I think) and has built-in charge planning to charge slower overnight. Even with all that, two years later, the battery is absolute crap. If I'm going to use the phone frequently (e.g. when travelling) I need an external battery to last though the day.
