Can I keep my Macbook Pro 2017 plugged in all t...

i would like to know if when plugged in does it use power directly from the charger or does it use battery...

Hi,

It uses a very little every week or so.

Today’s lithium ion batteries are completely different than batteries of the past, and some people still live in the past regarding battery care, such as advising you to “calibrate” your battery, which is totally unnecessary, or don’t leave your Mac notebook plugged in all the time. Given that, there are vastly differing opinions on how to treat Mac batteries.

If you run using the power adapter as much as possible, then you're saving "cycles" of which your battery has limited amount of (Apple claims “up to 1000” cycles). Age will also take its toll on a battery, no matter the usage. Some people will recommend running the battery down about 75% at once a month to keep it "exercised" which Lithium Ion batteries do need some of, but Apple has built that in to their charging circuit; after charging to 100% the battery won't charge anymore until it runs down to about 95% (which will occur naturally over time even with it plugged in), then charge it back up to 100%, etc.

Apple doesn’t say there’s anything wrong with leaving your Mac notebook plugged in all the time, nor do they say you need to discharge it ever (unless you’re not going to use your Mac portable long term) so they don’t think it’s a problem either: https://www.apple.com/batteries/maximizing-performance/

If, on the other hand, you want/need to use your battery with any frequency, go ahead, that’s why it’s there, to make your Mac portable and able to run out in the field with no power supply available.

You can run your Mac on battery for a little bit, then charge it back up to whatever level you want, and repeat this as many times as you want.

Although, in general, "common knowledge" is that it's not good to run down lithium-ion batteries all the way until they die, Apple doesn't say there's anything wrong with running your battery down to the point the OS puts your Mac to sleep.

In short, you can use your battery any way you want to.
