Very useful, thanks.

"Each cycle wears the battery down by a small amount and a partial discharge is better than a full discharge."
On top of that, high (dis)charge currents will cause internal heating and reduce lifespan as well. So the 'slow' recharge through the USB port is likely better for longevity than an external fast charger.
