New MacBook charger overheating and battery draining

Hi,

I bought a new MacBook just a few days ago (with the original charger included). On the first use, I noticed the charger was getting quite hot, even though I wasn’t running anything intensive on the MacBook.

Now, after 3 days of use, I’ve started noticing more issues:

Today battery is draining bit faster than expected (i noticed).
Yesterday, my MacBook became noticeably warm (using after charge) even with light use.
One of my apps froze and became unresponsive — I had to force quit the app and shut down the Mac manually.

I do not use while charging

Is this normal for a new MacBook during the initial days, or should I be concerned? Should I take it in for a check or replacement?

New MacBooks will typically run hotter as indexing occurs with use and installing/using apps and updating to a new operating system. Did you update the OS? This could be the reason for the issues you've stated. The charger will get quite warm when charging the battery. If the heat is concerning to you...

If you have concerns & while the MacBook is "new" (you state a few days), take it in to an Apple Store for evaluation. You have 14 days to return it for any reason and get a different one if you feel it's not performing as it should or to your liking. Apple will let you know if there is an issue or not.

And it's definitely not an issue to use the MacBook while charging. I'm writing this with my MacBook connected to a charger...it's only off the charger moving it from one room to another...99.9% of the time, it's on the charger. If you are near a power outlet, by all means use it. It will NOT hurt the battery and will reduce the number of battery charge/discharge cycles. Keep & conserve the battery for when you really need for it to be powered by the battery.

It's impossible for us to judge what "quite hot" & "gets hot" is. It's a fact thet chargers generate heat while charging. The general rule of thumb is, it's too hot you you to touch comfortably, then it's likely too hot. Apple can be the judge of that when you take it in for evaluation. Personally, I would take it in and have them verify if there's a problem (or not) with it.

I didn't update anything, and I’ve only installed Slack, VS Code, and Google, seems to be working correctly with that. I charge it from 40% to 85%, but the charger gets hot. Is it normal for it to get that hot, even though it’s new? I do not have any heavy tasks to perform, but the charger overheating seems like a separate issue.
