http://forums.androidcentral.com – I just bought a shiny new HTC one and am super pleased with it. A friend of mine (who has an iphone 5) recently told me that I should let the battery fully drain 4-5 times and fully charge it to 100% from 0% during the first couple of weeks - and then do it once a month thereafter to prolong the battery life. I did a search on this forum and people's opinions on this seem scattered. (HowTos)
