Not sure how reliable a blog is...but in general it's never a good idea to charge a Li-Ion battery to 100% (or discharge it to 0%). It stresses the battery. I have my laptop set to only charge to 90%. My EV set to 85%. My phone and tablet still charge to 100%, mostly because I have no control over Apple's walled children's playground. I don't really care on my phone because I just need it to last 2 years until I can get a new one. I'd like to think that manufacturers leave some overhead that isn't always used, but I doubt it.
