SUMMARY
My bluetooth mouse is kinda low on battery (< 10%) and KDE keeps warning me about it, everytime the percentage reading changes. This time it's 8%, minutes later it's 9%, later 5%, secs later 4%, then 5% e.t.c. I know it's low but it can keep going for at least hours. Moreover, KDE sends notification everytime the reading changes (at least that's what I guess), and it's annoying, there's literally pages of past notification in the list.

I see ppl try to solve it by lowering the "low battery" threshold, but I think there must be a better approach, plus you need to change the setting according to every device that has a battery inside.
Like, if the battery is low (e.g. < 10%), then warn the user only when the battery reading reaches historically minimum value? 
E.g. :
10% (warns) -> 9% (warns) -> 10% (doesn't warn) -> 8% (warns) -> 5% (warns) -> 6% (doesn't warn) -> 7% (doesn't warn) -> 80% (reset historical minimum value, because the user likely changed the battery)

STEPS TO REPRODUCE
1. Have a bluetooth mouse
2. Use it till the battery nearly dies

OBSERVED RESULT
KDE spams notification

EXPECTED RESULT
Smarter notification
