Re: Do you baby your other batteries as well?

My kids get the hand-me-down phones, and I used to have to replace batteries to make the phones usable again. "Babying" the batteries seems to really help make that not necessary.

I also REMOVE my laptop battery (usually for days at a time) when it is basically docked like a desktop. I have noticed that most peoples laptop batteries are "chewed up" due to constant charging.

Apple doesn't, at least not with any UI enabled by default in OS X.

Have never seen any such options on the my work laptop, a 2017 era MacBook Pro 15-inch nor my previous work machine, a early 2013 MacBook Pro 15-inch. I've never heard of any one else's MacBook Pros (at least since 2013) have such options.

I also have this Chromebook (https://www.asus.com/us/Laptops/ASUS-Chromebook-C201PA/) and it provides no choices.


Judging by the excellent longevity of my wife's Macbook Air, I suspect Apple chose a decent compromise between run-time and battery life and must have chosen a conservative voltage cut-off.

Keep in mind that (as with LEAF), the concept of "100% charge" is fluid. There's the 100% as presented to the consumer, and 100% as defined by the battery manufacturer -- both of which are arbitrary values chosen as compromises between run-time, longevity, and safety. So Apple's "100%" may be entirely different than another product's "100%" even if they use the same cells.
I noticed you're still working with polymers.

Cool, thanks for the feedback everyone!

Good point. My wife's MacBook Air from 2013 is still going strong with plenty of battery capacity. I just replaced my Surface Pro 3 from 2014 due to a depleted battery (was getting about 2.5 hrs on a good day, it was a 9 hr battery when new). Both computers probably spent a similar amount of time plugged in, so I expect that you are right on this point, that Apple did a better job of preserving battery life than did Microsoft in this case. Of course there will always be other factors...such as my Surface Pro 3 spending a year in southeast asia with me while I attempted to edits photos and videos on it...those high temps and heavy use surely expedited the battery's decline.

I would like to start doing this with my new computer to get the most life out of it that I can. I guess my only option is to create my own charging timer system, similar to the Leaf. Wish Microsoft had something built-in like those lovely Lenovos!
