Lenovo and other manufacturers provides configuration app to limit State of Charge for battery over a decade ago. Apple just implemented similar feature (but automatic) in 2020. Without that, battery is unnecessary degrading while plugged into AC with 100% SOC.

As seemingly half my coworkers needed batteries replaced on 2018 macbooks last year roughly as applecare ran out due to not being able to charge and work at the same time.

Honestly, has anyone gotten 1000 out of a MacBook? Mine always goes to "service battery" around 300-400.

I have a "Service Battery" notification since 3 years, still gives me 4 hours.

Can charge while working the machine still? Teams/Docker/etc chugging and charge % steadily dropped irregardless of port/charger used.

I got that warning on my Macbook Pro from 2014 after ~820 cycles.

So, somewhat close at least?

I think I got a pretty high number out of my first MacBook Pro before the battery swelled up like a bad bruise. But my current work laptop is now at 87% capacity with 82 cycles, so I don't have a lot of confidence in the battery lasting to 1000.

That's not been my experience, all the Dells I've owned have had great long lasting batteries.

Dell batteries last about 2 to 3 years of extensive use, we replace them all the time. They are easily replaceable though.

It's nice having a battery when their soldered ssds crap out after 5 years.
