partly yes partly no, your link describes charging with higher voltage decreases battery life this is different because voltage is same but current different
example: 3 chargers, our battery is 800mAh in capacity.
5v 400mA - battery charged in 2 hours from 0% to 100% internal chemistry react normal - better absorbtion
5v 850mA - battery charged in little less than 1 hour internal battery chemistry can be little upset cos risen temperature in reaction
5v 8000mA - battery cant quickly absorb this current in chemistry and will propably explode/leak/burn within minutes/seconds
this principle i mean
