Although I was told to charge my Android device before first use, it was already charged. Have I been given a phone rejected by someone else? I have just received my 'new' HTC one V. The instructions clearly state to charge the phone up before first use, yet the the phone switched on and showed full charge straight away, before I had chance to charge it. My worry is that I have been sent a phone that someone else has had and I really want to be sure it is brand new to me.
It is not uncommon that rejected/refurbished phones find their way back to the market as "new" ones.

But in my (and at least Al Everett's) experience, batteries are almost always shipped with some charge. I wouldn't worry, as long as there are no other indicators that your device was pre-owned.
