That's basically what it says, yeah. It's cool that you can just skim the three graphs and take away the main points of the article.

But that's hardly news.. The problem is that achieving these guidelines on a burning MacBook without an option to remove the cell is impossible :-/

Good thing the engineers know this all along and try to design so that the conditions are met to some extent.

I would just add to this, don't keep battery at 100% (unplug it when it's done charging)

Absolutely incorrect. What makes you think that keeping a 100% charged battery plugged in bad? The device has its own charging circuitry that stops charging when full.

Anedoctal evidence, my SOs Dell's battery is basically dead(about 2-3minutes of charge) even though it has spent 95% of time plugged in fully charged.

Laptop forums are full of stories like this.

I would have thought the charging circuitry takes care of this?
