But the real issue here is, unless some bug drains your battery, ideally you'd end up using less than 10% of the battery in a day anyway, so if you charge it almost every day instead of once a month and draining to 10%, but only charge up to 80%, then your battery would last 10-15 years instead of 2-3 years.
Probably draining to 40% and charging to 100% would still give you 5-8 years.
On the flip side, even if you abuse your battery in a kobo and end up reducing its battery capacity down to 15% of its original capacity, it'd probably still be usable, you'd just be forced to charge it every day of use anyway. So maybe there's not a lot of difference.  Except that charging 10% once a day might mean having it plugged in for 10-15 minutes. |
Annecdotal, but ...
I normally drain down to 30% and charge to 100%, which is around 3 weeks, and all of my readers have lasted more than 3 years. My Glo HD is going on 5+ years and I'm not noticing appreciable battery loss.
Although that 40% to 80% sounds nice, I'd just assume plug it in and forget about it; I don't mind monitoring it as it approaches 40%, but monitoring for 80% sounds like a PITA. I'd just assume not do that and buy a new device (or replace the battery) in 6+ years.
If the mechanism is built in, great, otherwise I'll go for convience.
YMMV
