Macbook 16 2021 - Battery at Low battery health capacity after 2 years despite low cycle count and always being plugged in.

Talking about your battery being dead when it is still within Apple official acceptable service levels after two years is nonsense.

Batteries are a wear item, like the soles of your shoes and the tires on your car. Their expected lifetime depends on use (as reflected in Charge cycles) and also in the passage of time, used or not. After a while, you should expect to have to replace the battery.

Battery life also depends on two factors you may be able to control a bit better. Lithium polymer batteries deteriorate when they get too hot, and when they are subject to very deep discharge. These should be avoided when possible.

Despite using these batteries in millions of Apple devices, there is still a lot of of randomness in exactly which battery will fail when.

Apple SUGGESTS (but does not Warrant) that your battery MAY last as long as 1000 charge cycles, provided all other factors are well-controlled.

Apple uses the criterion that a battery that doesn't to hold 80 percent of its original charge capacity should be serviced, and likely replaced.

When designing systems, that 80 percent rule is intended so that, over a Very large sample of devices, almost all will be able to achieve their 'mission' -- still have at least 80 percent capacity at the three-year mark.

I am fairly disappointed in Apple that with a low cycle count of 96 and being 2 years old my M1 Macbook Pro is at 88% battery health. I am an expert in lithium batteries, and it is a best practices to discharge them to not less than 20% and charge them to not more than 80%. However, Apple's software keeps mine at 100% even if I set Optimized Battery Charging. Occasionally, I accidentally unplug my computer, but it takes weeks of being plugged in to reset to 80% charge, it is a really poor solution. Basically, Apple need to be highly aggressive in setting the laptop to 80% charge levels, Maybe a do not exceed 80% charge setting in battery health settings window. Another thing is running above 120F on the battery accelerate battery degradation, which my computer often sits at.

Anyone else feel the same, or have similar issues?

Why is apple not addressing this?

No one here can speak for Apple.

However you can submit your feedback Product Feedback - Apple

Does anyone have any solutions on how to keep the health where it is ?

Since you are familiar with Lithium batteries, you know that is not possible. Degradation happens over time and will always go down. If you are looking for a 80% charging limit option like what is found on the iPhone, then you can suggest Feedback to Apple here:

try getting a 100W charger that should charge it faster or if that dos not work try a new battery. For the overheating problem i would get a laptop cooling stand.

Keep in mind the Maximum Capacity could have a variation of +/- 5% and maybe you are on the low side of that variation at the moment. The Full Charge Capacity (FCC) does fluctuate by about 300mAh even on a good Apple battery. As the battery ages, this fluctuation can become more pronounced. Even a 200mAh fluctuation can cause the Maximum Capacity ratio to fluctuate by 5%. See my other post here where I show the math:

<< my M1 Macbook Pro is at 88% battery health. >>

Then your battery health is still good, and your Mac is operating as designed.

Batteries are only replaced under warranty when they can no longer provide 80 percent of the original service. Yours at 88 percent is fine.
