First, it assumes that one is willingly upgrading to Catalina from Mojave.
(One has to be a glutton for punishment to sink into the Catalina pit.)

Second, there is coconutBattery, which provides not just the current state of charge in mAh, but most importantly the depleted full state of charge relative to the designed battery capacity, reported in both mAh and percentage. Something that Apple refuses to do.

So, hard no -- my own opinion.

have fun on your outdated os then

This doesn’t work quite like optimized charging on iOS. Rather than using significant locations this takes into account just Hijra charging habits, battery temperature and the like.
Optimised battery charging says “learns from your daily charging routine so it can wait to finish charging past 80% until you need to use it”, so it takes the charging habits.

No thanks Apple, I don’t want my batt to not last as long, I’ll disable it, I change my MacBook every 2 years so it should be ok

Good on them for finally adding this.

For those with older MacBooks with MagSafe, you can cover up two of the center pins with a thin strip of paper to force the laptop into holding a battery charge level. I keep an always plugged in MacBook Air around 40% with this trick.

Does using a MBP plugged in the whole timed degrades battery?

I had three designers who each used loaded 2015 15” MacBook Pros as their desktop. They wanted them for portability, but never really ever took them home more than a handful of times so they stayed on the chargers all the time. At the end of the lease, one of them ended up with a bloated battery that required a trip to the Apple Store and a $200 repair. The other two seemed to be just fine. I cannot comment about any newer MacBook Pros.

My question is, why buy a MacBook Pro if you are going to leave it plugged in all the time? Just get an iMac or a Mac mini.
 
And they act like their doing us a big technological favor or something. Just give us a toggle switch (via software) to stop charging when the battery is at 80% SOC. IS THAT SO HARD?

Same with iOS. A simple slider switch to decrease peak voltage is all that every person on earth wants

Well, I for one really look forward to this. I have an 18 month old 13" macbook pro that has just had a new battery under warranty because the old one had swollen to the point that the base of the case touched my desk before the feet did. It's used 90% of the time in a 12 south stand in clamshell mode, driving two monitors through a thunderbolt dock- no external power means it can't drive the monitors so it only gets run just on the battery when it's not being used at my desk. The thought of this repair at my expense does not bear thinking about- new bottom case new keyboard/track pad and even a new base to the bottom case- essentially a new laptop less the screen. (it keeps the original motherboard though). It's more or less cheaper to buy a new mac mini than to suffer this repair at your own expense!

If I can keep my battery at 70% I will be a very happy bunny!

I wish they would do it like Tesla does on their cars. You can limit full charge to whatever percentage you want. Me, I'd keep it at 70% forever. You can get 10 years out of a lipo battery that way.
 
I don’t own a MacBook (maybe one day!) but it’s a shame Apple, as well as other companies, don’t allow for the end user to swap out batteries once they’ve reached the end of the line without having to either get it replaced by the company themselves or using a third party solution.

The first step in their ability to brick your computer if they are not happy with how its battery is functioning.
 
The difference is everyone else had this feature in clunky, ugly, and inefficient third-party utilities, as you show, and not built-in to the native OS.

Exactly, they hardly worked. I've used these in the last 10 years. They always lost the true state of the battery, so I'd unplug at 80% or wherever the app held the battery at and BAM laptop shut off because it was really at 0% but the application thought it was at 80%.
 
Off topic, but have the popping sound issues on the 16“ been fixed in this version? The last version didn‘t fix the problem and many people are waiting for this.

This is good, given how extremely difficult and expensive it is to replace the battery in Apple laptops.

Understandable how the batteries work, but did plugging in a laptop just get complicated? Thought it was as simple as plug it in, it charges the battery till it hits a peak of 100% then switches over to the power cable. Might an oversimplification.

Guess they need to accommodate for when a wire is removed, and the laptop needs to switch over to a new power source?

The problem is that currently you can either: 1. have it plugged in which keeps it charged at 100% all the time, or 2. unplug it and drain the battery until you need to charge it again.

If you're at home all day (like most people now) and don't need to run off battery, the best thing would be to plug it in and have the battery only charge up to 80%, then stop charging. This way, your battery doesn't age unnecessarily.
 
Finally. But for crying out loud, bring it to iPads.
On tablets it makes very little sense unless you abuse it... like mounted to a wall for smart home control where it is permanently connectd to a charger. Tablets draw very little power from their batteries (the battery has very large capacity compared to the power draw) and are mostly used disconnectd from AC. They also have a very long battery runtime, means it doesn't get charged often.
Meanwhile, everybody else has had this feature for over a decade...
[...]
Yes... I had my Dell set to charge to 95% only and start chargin only at 85%. On AC this will greatly reduced wear on the battery.
For machines permanently connected to AC where battery can't be removed, the charge start should be set to like 45% and stop charge at 75%.
However, in that case battery calibration should be done once every ~4 month, i.e. full charge, discharge to empty and full charge again, then set charging threshold to values above again.
