HTC touts the One X battery life

While individual daily usage patterns and battery life will vary, we’ve been working diligently to balance performance with design and functionality goals. For example, we held multiple focus groups with real-world users to find the right balance between battery and phone size. Our research was clear: you want your phone to last all day, but you also want your phone to be thin and light.  So we set battery performance goals alongside design targets and relentlessly pursued creating gorgeous phones that work throughout a long day.

Of course, one of the first questions we usually get is about battery size, “why is the battery only 1800 milliamp hour (mAh)?  Why not 2050, 2400 or even 3600-mAh?”  Well, Moore’s Law doesn’t apply to batteries.  Unlike a computer memory chip, where the size of the chip is constant and fits in the same slot regardless of how much memory it has, a higher mAh actually translates into a larger battery – which impacts the overall size and weight of the phone.
