Hey, I have a 2019 MacBook pro, I was wondering I should have it plugged in all the time, keep the battery at 100%, or should I let it drain to 30ish %. Which method will preserve my battery life?
My battery condition is normal as of now

You can plug the computer in whenever needed or convenient to do so. Leaving the computer plugged in will not damage your computer or your battery. Let the MacOS manage the system power/charging. it does so very well and there is no need for you to micromanage the system.

Yes you kind of prolong the battery life by keeping number of the charge cycles low.
A battery has a certain number of charge cycles, after which the battery life will decrease.
...
Batteries have a limited amount of charge cycles before their performance is expected to diminish. Once the cycle count is reached, a replacement battery is recommended to maintain performance. You can use your battery after it reaches its maximum cycle count, but you might notice a reduction in your battery life.

I've been using my MacBook Pro from 2012 for years being plugged in all of the time during daytime.
From time to time I used it for a couple of minutes without charging it.
By the end of last year I had to replace the battery, because the "service battery" message came up.
Letting you battery deplete to 30% won't hurt it.Get help with your Mac notebook battery - Apple Support
so basically it preserves battery life right?
