Found some ways to better control the battery on my Nexus 5X (with franco.Kernel installed); can't do the same with my Nexus 9.
I am able to get detailed battery status through /sys/class/power_supply_bms. Current full charge capacity is 2538 of 2704 mAh (93.9%), computed using charge_full and charge_full_design.

Welp, just ordered my Nexus 5X.
Had the phone for 7-1/2 months so this is okay, not great.
The best part, however, is that I am able to programmatically enable or disable charging by echoing 1 or 0 to /sys/class/power_supply/battery/battery_charging_enabled.
10-12% loss of capacity per year is normal but it's still more than I'd like.

Can you do something about it? :/

That's why I'd like to programmatically disable charging at less than 100% but keep it plugged in.
I found this functionality on my device while mucking around as root looking for appropriate controls.

ah
i'd expect the battery controller to be doing that anyway

I am still able to check the current (not full charge or design) capacity on my Nexus 9 at /sys/class/power_supply/battery/charge_counter.
The counter hovers at around 6210 mAh when fully charged, about 92.7% of the 6700 mAh specified full charge capacity; this is good for a device that's more than a year old (bigger batteries are charged and discharged slower, which reduces stress).

Just got my Nexus 9, along with the official keyboard folio to go with it.
