I have a nexus 6p, and various different chargers which I bought for the phone. One is a slow USB charger (comes with the box).
Another is a type c to type c cable connected to the AnkerCore 20100+ battery pack (this charges quick charge too but I charge that with a USB mini so the current is different).
I also have a charging dock and sometimes use my computer to charge it, along with a wall charger with the highest speed.
Does this effect the battery in any way and does it effect the time before I have to charge it again?
