Only good things I can say about the RAZR HD:
-Battery Life: more like a 18 hour with heavy usage, but yeah 24 hour life while mild usage.
-Screen is beautiful. 1280x720 is better than my old HP monitor! Colors are vibrant and pop out.
-I get great 4G reception where I live, so webpages load quickly and apps download in just seconds.
-Personal Preference: I love the design! I have the White RAZR HD and it's very attractive to look at. I love the kevlar back cover, nanotechnology covering to prevent liquid damage (although not tested personally) is a welcome additon for when I take my phone to the bathroom while I shower to listen to Pandora. The build feels light yet sturdy.
-The best thing yet: near stock Jelly Bean. I had a Nexus 7 with JB installed, and Moto's OS is so close to stock JB (with minor tweaks), you'd think it was a Nexus phone.
