I have two Dell XPS Laptops, one 13 one 15". Both have this Dell Power control, where you set below which percentage your battery will charge, so you can leave it plugged in without being concerned that it charges when it is at 80%.
Also, you can limit the charge between 50 and 100.
All this is handy, but… oh there is a but(t)…
…
Both came with “8%” battery wear. Even though they are still good… don’t understand. AND, … … there is an “AND”…
I had to change the 15"'s battery because it didn’t last anymore more than 3 hours. I bought a new one, said “Dell”… and when I first had it in, “8% battery wear”

It’s still working quite well, but… and…
My V’s (which arrived I think a year ago?) has still… 0% battery wear…

While a power control is nice,
AND I would like it as an app NOT in the BIOS, pretty please!!!,
BUT maybe not necessary?
if still working like the V1 battery?
