But what's the problem? If the One is at 25% by the end of the day, then you made it. Why do you need more?
I suspect most people have a psychological breakdown as a battery indicator winds its way from 100% to 0% throughout the course of a given day. For example, they get "nervous" when the battery gets into the 80% range, become "concerned" in the 70s, "panicky" in the 60s, "fearful" in the 50s, "psychotic" in the 40s, "suicidal" in the 30s, "have a religious awakening" in the 20s, "find God" in the 10s, and "accept their fate" by 0. Yes, the One should have had a 2800 to 3200 mAh battery inside, and HTC was more interested in aesthetics and hand-comfort. Once again, you're holding a computer in your hand with some specs better than any laptop on the market. It's naive to assume the battery will last from 6:00am to midnight with all radios blasting, games, web surfing, streaming movies... No way. Only the Note 2 can do that, and its size renders it impractical for 98% of the smartphone public. The One does an excellent job if you know how to manage it properly.
