My Note 8 phone has a charge battery notification at 15 percent.
I just replaced that phone, and yes with another one because I happen to like that model a lot, and my old one did 1500+ cycles with respectable battery capacity remaining. I replaced it due to a cracked screen, not battery trouble.
My general experience has been to avoid fully charging the battery and leaving the device on the charger, plus avoiding high demand use under 15 to 20 percent adds very considerably to longer term battery health.
This has played out across a number of devices, lenovo laptop, various phones.
After, say a few hundred cycles, it's very important to avoid taking the battery below 5 percent or even to zero. When that happens, the battery capacity is reduced every time, and it's by a significant amount.
