Optimized Battery Charging difficulty for 2023 MacBook Professional, Apple M2 Max chip

I am submitting a solution with this query – not as a result of I really feel it is the last word reply, however solely to ensure that at the least one reply is posted earlier than the query is closed as a Duplicate. Please word that I do not really feel it truly is a reproduction, although there have actually been comparable questions; questions principally alongside the traces of, “Why Does not ‘Optimized Battery Charging’ work as anticipated?”

That stated, this reply addresses the alternative possibility (as in change Apple’s “Optimized Battery Charging” function) within the query.

I’ve checked out a couple of choices for alternative of “Optimized Battery Charging”, and carried out a little bit of analysis/studying. A couple of of the references I used for this reply are listed under. This is the solutions:

It appears that evidently there are various who’re both dissatisfied or confused with Apple’s implementation of “Optimized Battery Charging”. Attempting to offer Apple credit score for what they do, I suspect this has one thing to do with their penchant for inscrutability; maybe they really feel it is not of their buyer’s pursuits to speak particulars relating to their macOS? For instance, one attainable clarification for the apparently errant conduct within the query is given in a passage from the AlDente documentation:

Holding your battery at a decrease share, reminiscent of underneath 80%, over weeks with out doing full cycles (100%-0%) may end up in a disturbed battery calibration. When this occurs, your Macbook may flip off with 40-50% left or your battery capability will drop considerably. Nonetheless, that is solely resulting from a disturbed battery calibration and never due to a defective or degraded battery. To keep away from this difficulty, we suggest doing at the least one full cycle (0%-100%) each two weeks. Even when your battery calibration will get disturbed, doing 4+ full cycles will recalibrate your battery and the capability will go up once more.

Good clarification, but it surely does not appear to suit the sample described within the query. Moreover, among the dialogue in References 7 & 8 (and a few questions right here on SE) counsel that one thing is probably not fairly proper with “Optimized Battery Charging”.

Apple’s sponsored on-line boards inevitably present no helpful info explaining why “Optimized Battery Charging” seems to be working incorrectly. AFAICS, there are not any solutions from Apple (or anybody else) for restoring the performance of “Optimized Battery Charging” underneath the situations cited within the Query.

So, let’s consider some options; the options mentioned right here all implement what could be known as “Restricted Battery Charging” – versus “Optimized Battery Charging”. The apps are additional restricted to these supporting Macs with Apple Silicon – not Intel processors:

• AlDente [REFs 1 & 2] is obtainable in a free/open-source model, and in a “Skilled” model. The performance of the free model is somewhat restricted in comparison with the Professional model, however the free model does assist the handbook utility of a restricted cost capability – and subsequently meets the standards as a alternative; i.e. “Restricted Battery Charging”. There may be some attention-grabbing studying in among the AlDente points; this one seems to doc the invention of how assist for the Apple Silicon Macs got here to go!

• Battery-Toolkit [REF 6] and AlDente are each coded in Swift, and have a GUI interface. By means of comparability, alDente is a couple of 12 months older than Battery-Toolkit, and has a bigger following. This will likely clarify why alDente has a a lot bigger set of Open points.

• battery [REFs 3 & 4] is notable because the authors applied a CLI model of “Restricted Battery Charging” (aka cost limiter) for Apple Silicon Macs. This occurred whereas they had been looking for an improve to allow restricted battery charging assist for M1 in bclm – as documented within the dialogue of this difficulty. Be aware that the invention of SMC keys in firmware by the Asahi Linux venture, and a short polling script contributed by ‘@thloh85’ had been instrumental within the improvement of battery.

  The CLI model of battery is a tiny 17kB bash script put in at /usr/native/bin/battery. The “lively” a part of the script is contained in a half-dozen capabilities that set SMC values. Of some significance (IMHO) is the truth that battery has an un-install possibility – in case you get bored with it or resolve to return to Apple’s “Optimized Battery Charging”

• Lastly, batt (REF 5) can be a CLI device similar to battery. It is newer than battery, and consequently has not achieved as giant a following. The README.md on the batt GitHub repo is informative, and value studying. It additionally has an un-install possibility within the script.

That appears to be what’s on provide for “Restricted Battery Charging” for Apple silicon-equipped Macs.
