FWIW, iOS 13, Apple's latest version of the iPhone operating system, charges the battery to 80% and holds it there. It's AI algorithm tries to figure out when you're going to need the phone (i.e., will take it off the charger), and tries to time the remaining charge to 100% for that event. Of course, that won't work too well if you don't take your phone off the charger roughly at the same time each day. Also, I've seen some differences in how close it gets to 100% when charging wirelessly or wired -- i.e., it gets to 100% more often with wired charging. It's possible the AI doesn't take the difference in charging speed into account.

Charging Lithium Ion batteries I recently read that Lithium Ion batteries should be charged only to 80% unless you are going to need full capacity. Supposedly makes them last longer. Anyone ever heard of this? If true does this also apply to LiPO4 batteries?
