I’ve been monitoring the wear daily for some time and yesterday forgot to plug in so did a full discharge and charge whilst powered off.
This is an 8 month old battery that for most of the time has been set to have a max charge of 78 and is used for 6 hours a day plugged in.
In the first graph the dip is were I had forgot to reset the BIOS from my 78% to 100% so I had to power on set the BIOs to 100% and power off. You will also note the time of the data i.e. the period between the times I moniotred are not regular.
The second graph is evaluated from the first with a regular time.
I won’t comment much on the graphs as is pretty clear as to how the battery charged.
