Take the 2-minute tour ×  I usually disconnect my cellphone from
the charger some time after it's fully charged because I'm
afraid the battery could lose capacity over time if I don't.
However, I believe modern electronics should be able to handle
this kind of scenario and automatically stop charging the
battery once it's full. Does this apply to modern Android
phones? Or do I need to continue disconnecting it all the time?

most cell phone batteries are Lithium Ion now.  Although
constant charging cannot hurt, it looks like you may want to
periodically run the battery all the way down so the digital
circuits can correctly calibrate:  Although lithium-ion is
memory-free in terms of performance deterioration, batteries
with fuel gauges exhibit what engineers refer to as "digital
memory". Short discharges with subsequent recharges do not
provide the periodic calibration needed to synchronize the fuel
gauge with the battery's state-of-charge. A delibe
