1,000 battery cycles
Most current Macs (MacBooks, MacBook Airs, and MacBook Pros) use batteries assessed as having 1,000 battery cycles. That's pretty much good enough for at least three years of regular use.
Your battery might drain fast when you're working on your Mac because, for one reason or another, you're running one-too-many apps at the same time. ... To do this, simply click on the battery icon on the top right corner of your screen, or run the activity monitor app.

I say it depends if you got the computer at the beginning of the year. If you got it later in 2019, go to the apple store and ask.
