"Sieve" doesn't really describe the DROID 4 leaks at this point. In amongst a smattering of press images for the as-yet-unconfirmed phone (as if we needed it at this point) came a direct comparison of the DROID 4 and DROID RAZR, courtesy of Droid-Life. It reinforces a lot of the specs that we've already seen, like a 4-inch screen and an LTE connection, but gives us a little more insight into the nitty-gritty details.
In a one-sheet labelled "evolve or dissolve", the company pits the DROID 2 GLOBAL, DROID 3 and DROID 4 against the RAZR, withe the 4th revision obviously coming out on top. Some highlighted differences include the qHD screen, which on the DROID 4 definitely is not a Super AMOLED, probably settling for a standard TFT LCD panel. The 1.2 Ghz dual-core processor, 1 GB of RAM, 8 MP camera, HDMI camera and Motorola-customized Gingerbread remain. The principle differences noted include a tiny bump up to a 1785 mAh battery and a "laser cut edge-lighted keyboard" that illuminates the space around the individual keys.
Dimensions aren't mentioned, but from previous leaks we're pretty sure that it comes in at 12.7mm - still pretty slim for a QWERTY device. Also notably absent from the comparison is the replaceable battery, but it's likely that Motorola and Verizon don't want to highlight the RAZR's non-removable power source. The current scuttlebutt places the release at December 8th, possibly alongside another long-awaited phone.
