Has Mac laptop batteries improved in technology since 2017?

[MacCheetah3]

everything I've ever read about battery chemistry says that going all the way to 0% is bad for the cells

Just one more thing… A mostly just for fun reminder of when it was recommended to frequently/often perform a full charge cycle because it actually did have a notable benefit.

It also reinforces my point that a lot of “advice” is just mindless parroting.

That was also when laptop batteries were NiCad instead of Lithium Ion, so both the chemistry and physical construction of laptop batteries was different.

My 16' MBP is used as a desktop for the most part (clamshell mode with an external monitor). It is used heavily - all day long (Parallels during the day, gaming at night, etc). I use AlDente to keep its charge around 60-75% and run off of wall power resulting in basically no battery usage or cycling for weeks on end. Every few months I'll run it down to 20% and then charge to 100% just to keep the % reader accurate. This has worked REALLY well for me and battery health seems to indicate the battery itself is happy with this very light usage despite the many years of use.

Compared to my 2017 MBP 13', I didn't have AlDente and I am not sure if the laptop bypassed the battery when plugged in like this generation does, but I remember <2 years my battery health was way below 80% - the blazing hot Intel chip probably didn't help either.

I don't think battery technology has really changed that much since 2017, we're just a lot easier on them (with Apple Silicon temperatures) and less extreme draws.
