i don't know any smart phone that have high specs and don't need a daily charge, its just a case of surrounding yourself with chargers.. or get in the habbit of charging at night for like me for 1hour when i get up. yeah i can eek a day and a half out, maybe two if i turned everything off, but then i run the risk of getting caught short. i charge each morning, never runs out.. also cheap ebay docks are great for docking at work
