What is CC and CV?
A CC power source will maintain current at a relatively constant level, regardless of fairly large changes in voltage, while a CV power source will maintain voltage at a relatively constant level, regardless of fairly large changes in current.
Which battery can charge faster and has better charge cycles?
Li-ion can be designed for a fast charge of 10-minutes or so but the specific energy of such a cell will be low. Ultra-fast charging only applies during the first charge phase. The charge current should be lowered after the battery reaches 70 percent state-of-charge (SoC).
Is Fast Charge bad for battery?
Unless there’s some technical flaw with your battery or charger electronics, however, using a fast charger won’t do your phone’s battery any long-term damage.
