Apple Releases macOS Catalina 10.15.5 With Battery Health Management Features, Fix for Finder Freezing

I know for a fact this is a clear case of planned obsolescence by Apple.

How do I know this?

Because I have written some software to do precisely what Apple is doing here, as a "weekend" project (OK, took a little more than a weekend, but not that much more). If I may say so myself, it's a much better implementation than Apple's, because I control when I want the computer to charge or not. And it has been successfully tested on computers that are older than 2016, including my wife's 2014 MacBook Air, which I monitor closely. So technically nothing prevents Apple from implementing this on older computers.

Before anyone asks: I could easily post this code on GitHub, or sell it, or whatever. But I can't do that because knowing Apple, they'll find a way to restrict access to this API (who knows, maybe they already did on 10.5.5? Though I can't say if the API they're using is the same I'm using.)

I just wanted to point out that Apple is doing this on purpose to get people to upgrade. I know theories of planned obsolescence abound, but rarely can you confirm them like I just did (as a matter of fact, anyone reading this can't really confirm what I'm saying as I'm not showing the code or the app; but I don't care, because I know it's true).

Since you don't care, you shouldn't mind my saying that you're blowing smoke :)

But seriously folks, perhaps someone who "really" knows might say what if any hardware limitations, perhaps even on the batteries themselves, might limit this feature. Such a limitation is not illogical in itself. Either that, or maybe someone knows the name of this special, double-secret-probation API :)

Apple has abandoned us Sierra users(i have my reasons)

Very good as I primarily use my MacBook Pro in clamshell mode. Keeping my battery at 100% for the past month can't be good for the battery.

Tesla cars by default charge to 90%. You have to manually set to 100% if you know you're going to need it the next day (like a road trip). And Tesla definitely has their battery knowledge down. Their scientist recommends 70% for maximum longevity if you know you're not going to need it.

whats the science behind this? Why I shouldn't use 100% capacity of the battery?
what about plugged in which reaches 100% all the time.

Battery health management couldn't come soon enough, since once your battery dies, you can't replace it.

Indeed, I fully support some healthy skepticism. If I were in your position I wouldn't believe my own claim either.

If, hypothetically, you did, you might as well believe that I tested this on a few pre-2016 MacBooks, and never saw it fail. Essentially, if Coconut Battery reports battery health information, my app should work with it.

Hope it fixes the multiple issues introduced by the previous release:
1. Crash after awaking from standby
2. Touchpad and keyboard unresponsive after awaking (sometimes even the external Bluetooth keyboard/mouse assistant showing up, like no keyboard/mouse was detected)
3. iPhone keeps “ejecting” when trying to WiFi-sync

I’m having the second bug too, for months now. Highly annoying.

I use my MacBook, iPad and iPhone plugged in when I can, which is most time, in past months is all day long.

My iPhone 8 Plus, purchased 16 months ago, has "Maximum Capacity 99%", so I really don't care about Battery Health Management, I disable it.

Dont believe the battery health rating. Try Coconut battery for Mac to evaluate what the battery condition truly is...

How can we tell if the battery health management is working? It just won't hit 100%? I see the option is automatically turned on in energy saver preferences though....

You can use 100% of your battery's capacity, just don't expect it to last as long as if you accepted some compromises intended to maximize its lifespan. As with anything in engineering, there are tradeoffs -- if you want your battery to last as long as possible on a single charge, just don't expect it to last as many charge cycles as possible. Nothing prevents you from driving your car in the redline all the time, just don't expect it to last for as many hundred thousand of miles as your neighbor's car who drives it at 2000 RPM all the time.

Apple is doing this, Tesla (and probably every other EV manufacturer) is doing this. Did you know the Prius battery only uses 40% to 80% of its range? i.e. when the battery display is showing the full 8/8 bars, it's actually at 80% charge.

Like it or not, that's how batteries work.
