Using a new laptop with a confirmed healthy battery, do you typically need to do battery calibration after a fresh distro install? Or is that only used when replacing a battery on an existing system?

By battery calibration I mean the multiple cycles of letting battery drain to 0% and then recharging back up to 100%.

Thanks in advance!

    You don’t even need to manually keep your battery in the 20-80 range nowadays since almost every charge controller automatically monitors temperature and adjusts charging parameters to not damage the battery.

    Sort of. The charge controller will limit charging current if too far outside normal temperature ranges. But it will still charge all the way to 100% unless you manually limit that with the settings on your device.

    Heck, lithium ion batteries nowadays last longest the longer they’re plugged in.

    That’s actually incorrect, charging a Li-ion battery to 100% is significantly worse for it than charging to 80%, and keeping it at 100% plugged in is even worse. Which is why most devices will have the option to stop charging at 80% or near there instead of going all the way to 100%.

    Charging while warm is also much worse than charging below 50 degrees F or so.

      While you’re right that going all the way up to the 4.2v that the battery is rated for is worse than if it just stayed at 4v, by not discharging to half or more you’re reducing the charge cycles which directly correlates to longer life.

      Ultimately in lieu of a charge controller or os that does that for you, the easiest way for a user to extend battery life without going psycho mode is to charge they phone, eat hot chip and lie.

      I know all the macs and iphones have that predictive charging thing where if you’re always leaving your phone or computer or phone plugged in overnight they’ll keep it around 80% or so till about an hour before you wake up and charge the rest of the way then.

      Windows computers have something called smart charging but I don’t have any experience with it.

      Theres a bunch of different ways to control charging in Linux.

      It really seems like this is a solved problem and I’m glad to not be worrying about plugging and unplugging my phone to maximize my battery life.
