No up or down

or replace the battery with a spare

Sadly, not with the newer phones :'(

fun fact: just recently my brother pointed out that I was using an mp3 charger, and it still worked. the company was not even close to Samsung, it was a Taiwanese company.

can still be a micro usb, it'll work with most, all phones have been asked by governments to make the chargers standard, Apple is the only one that didn't go micro usb and uses their own "standard" plug

So true! I've had over 4 chargers over the past year...

Nokia doesn't need a charger :')
