I've said it before and I'll say it again: one of the things I like about HTC's One series is how much they've improved the battery standby time.  Say what you will about overall usage time (I'm still gauging results myself), but after charging the HTC One X+ yesterday evening, putting it through some light usage, and leaving it on my bedside table, I had 93% battery this morning.  I dig the personalization touches in HTC Sense 4+, and the HTC Sense keyboard is significantly improved in Android 4.1.
