One of my pet peeves is how people get so dismissive about limiting their battery charge. People will even get defensive, as if it is a personal attack or something. Empirical evidence has shown time and time again that it is a-matter-of-fact that stopping charge at 80% will prolong a lithium-ion battery. [1][2][3]

I mean, it’s one thing to be believe that it is “too inconvenient” or that “life’s too short to micromanage my phone battery”, and another to blatantly spread lies that stopping charge at 80% is a “myth” with no benefit. And maybe that “micromanagement” argument was true 5 years ago, but nowadays nearly every device can automatically limit charge levels, e.g.:

iPhone 15 and above

iPhone 14 and below with a smart-plug[4]

Most Samsung phones/tablets

Sony phones/tablets

Any rooted Android

Any decent EV

Windows: Asus, Dell, HP, Lenovo, and Microsoft laptops

MacOS through AlDente[5]

Linux: TLP for most manufacturers[6]

And honestly if your device can’t automatically limit charge, I concede it probably isn’t worth the micromanagement. But those kinds of devices have small, cheap, and easy to replace batteries anyway.

It’s a heck of a lot different to drive to the Apple Store and spend $250 for a MacBook battery versus the $30 battery and half hour of work for Nintendo Switch.
