Bug ID: 417464
Summary: Limit battery charging to e.g. 80% to improve battery
lifetime
Product: Powerdevil
Version: unspecified
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: kje...@kjernsmo.net
Target Milestone: ---
SUMMARY
There's an interesting article on prolonging battery life at:
https://batteryuniversity.com/index.php/learn/article/how_to_prolong_lithium_based_batteries
They recommend:
"To make this feature user-friendly, a device should feature a “Long Life” mode
that keeps the battery at 4.05V/cell and offers a SoC of about 80 percent. One
hour before traveling, the user requests the “Full Capacity” mode to bring the
charge to 4.20V/cell."
So, it is basically my wish that this is implemented in KDE. You can't do that
now, right? If not, it seems like Powerdevil would be a nice place to have a
setting that limits the charge to a certain percentage of full, and then
possibly a plasmoid or something that makes it really easy to override that
like they suggest.
If I understand it correctly, there is stuff in TLP that can help with this, at
least on some system, but I don't know if that's the appropriate way to
implement it.
