75%-65% algo

[alex99r]

the battery optimal is 75-65. the algo should be able to stay at 75% (or apples 80%) then charge to 100% or stay at 75%. After some time (for example 2 hours) the battery should discharge to 65% then again spend some time there and then back to 75%. (this describes an ideal case of battery travelling to 75%-65% percentage maintaining the ultimate maintenance for battery longevity after the best charging combo. (other combos from best to worst include by ranking 75-45, 75-25, 85-25, 100-40, and many others.

We can call this the charging algo since its the idea behind desktop mode of a connected a macbook pro with no support to macOS Battery Health Management.

For this algo you need time left at idle charging state (i.e. 80% set) for 2 hours while charging. This time is also useful for another algo that could replicate Apple's implementation that is now missing from the unsupported models. Any strategy is possible by the user.

Congrats to the discharging feature hope you can bring it to Intel too soon. Cheers!!

I think so

Doing a research and will report back

Interested in finding out other tests pointing to this since COVID became a thing

Alex! Please check my recent post on the discussion page. I think it could interest you because it would allow the battery to stay between 75 and 65% for a long time without cycling in-between at all, or too often for that matter. Cycling in between those two value will still wear and tear the battery as there are still small cycles created which add up to full cycles eventually as well. Of course it isn't as bad as always cycling in between 100 to completely empty, but still. In my opinion the best case scenario is if the battery holds a charge (anything in between 80 and 20%) but is neither drained nor charged by the user. Meaning it basically is just left alone to slowly self-discharge over a considerably long time. I don't think its necessary to have the battery percentage 'travel' around all that much, down to 65% and then again to 75 and so on and so forth, as you mentioned. I don't get the point of that, so if you could elaborate your thought pattern behind this please :)

You're probably right !!

No point in traveling in cycles. Keep an SoC between 40-80 based on literature. Voltage increases with SoC. I am trying find more info on the best stable SoC and what matters. Don't forget to cycle every 30-90 days at least once.

LOL: So if you are having issues with throttling maybe set SoC towards 40-50 or if you're over clocking and need more juice increase the SOC.

[alex99r]

Charging the battery from 80 to 100 is based on the premise of going out and using it away from a plug, just like a phone.

Not having control over that seems totally archaic to run to the wall to charge your juice and then unplug it to consume it right sat in the same position.

Need control over desktop mode and going out in 30 Mins mode. Just like Apple HBM system but more conscious about Laptop at home. Today we found out a simple 50% fixed SoC was all the fuck we wanted from the start with an ability to charge fully cause I'm going out and I'm taking it with me.

@jpirnie which MacBook do you have/how old is it? maybe the new key simply does not exist on your machine.

Looks like the latest version v2.1.2 has fixed the issues I was seeing. I made sure to turn off allow discharge and it seems to be staying where it should. I'll let it run for a day and see what it looks like.

Maybe another option would be to let that option to discharge to stay on until it reaches the destination charge %, then automatically turn it off. Otherwise you get that weird cycling thing going on.
