Battery concern (40-80)

[Sheenaynay]

The ideal battery percentage for lithium-ion powered smartphones lies between 40-80 %.

If you're supposed to keep it between 40-80 %, How are you supposed to keep your charging cycles minimal.
Since you're only using 40% of your phone's capacity you're going to have more charge cycles for sure.

NOW That leaves the question..
What's more important, having less charge cycles but charging all the way up to 100% from 20%

Or plugging in the charger when it hits 40% and plug it out when it hits 80%?

I charge to 100%, modern devices have regulator circuitry that controls the charging /discharging of batteries. Plug in at night, unplug in morning...
