I have had an erratic/irregular plug-in schedule since I switched to the MBP 14", and as a result Optimised Battery Charging (OBC) does not work well (or perhaps even at all). This is in contrast to my 16" i9 which was plugged in all the time, in which case OBC worked very well.
I just need a toggle for enabling/disabling charging - and I am currently using AlDente Pro to do so. Will submit a feedback and perhaps invoke the popularity of AlDente to make the case.
p/s: The reason I don’t necessarily have to live with 80% charge is because the MBP 14" is so efficient, even with M1 Max 32-core GPU. I use a 30W charger most of the time, but the M1 Max consumes 60W when I ran multi-processing (multi-core) scripts in R/Python. So, the battery will slowly drain while the CPU is churning. Rather than having the battery charged to 80%, I will just pause any charging and let the charge level stay where it is, until I know I need to be on the go again. It takes so long for the charge level to drop that it’s hard to put charge cycles on the battery, which is a good problem I suppose.
