I would backup data, test for strange noises with and without the charger attached, and then shut down/restart.

I would then use my battery more regularly, than leaving the charger connected.

What sort of noises?

Why? Batteries cost money.

Because lithium batteries don’t like being on charge permanently. It’s important to balance charger and battery use for longest battery longevity. Many people falsely believe that keeping their MacBook/laptop connected to its charger will reduce cycles and improve longevity. This is untrue and we see many batteries failing prematurely with low cycle counts.

Same reason modern MacBooks detect regular charger use and offer to lower battery to 80% and run off charger instead.

Exactly - a 2019 MBP should do this for the OP without any intervention on their part. Stressing it any further is unnecessary.

To be honest, I’m not sure if they offer this. I went from a 2015 Retina to M1, and skipped the last generation of Intels. Regardless, it’s still important to let things tick over in lithium batteries, and not keep them permanently charged, or permanently unused.

I need mine to be at 100%, so I keep it at 100%. Fortunately they've make it a lot easier to replace batteries on the M1s.

Nothing wrong with keeping it charged at 100% when you're regularly using your battery out and about. The problem is keeping it charged at 100% when not regularly using the battery.

I thought Macs had a good charge controller

Batteries hate being at 100% just as much as they hate being at 0%.

I think they've switched to a less robust adhesive with the more recent models, at lease compared to the 2012 mbp I tried to do a replacement on.

Anything besides 100% is not an option.

For clarity you're referring to the first of the Retinas in 2012 which were a pain, and not the last of the Unibodies in 2012 which were easy. But in many ways the newer Macs have become a lot more complicated. Less repairable and serviceable by design.

They aren’t on charge permanently.

Apple doesn’t run power to the machine “through” the battery like most others.

MacOS will look after the battery, no human intervention required.

Would love to show you some of the older, low cycle count MacBooks I’ve seen!
