I have had my One X+ for about 3 days so far. I'm coming from an iPhone 4, and so far the battery life has me a little nervous. Other than that I love the phone. I don't have any hard numbers, and I realize that being a new phone I'm using it more than I will under normal conditions, but it still seems like the battery drops much faster than I would anticipate. In addition, when it's plugged in, the battery percentage goes up quite slow. I've even seen some instances when I'm plugged into a 1 amp charger, and the battery percentage still goes down if I'm downloading and playing a game for instance. Is this normal? Is there such a thing as a bad battery and I should bring it back to exchange it?
