Droid-Life, which earlier showed off images --- and a possible date --- for Motorola's upcoming Droid 4 refresh of its flagship Droid device, has more details on the device, which is being delivered very quickly after the launch of the Droid 3, which launched in mid-July.
It's a prime example of Android fragmentation, but the Droid 4 will should provide updates that fill holes in the Droid 3 feature set, including adding Verizon 4G LTE support, a 1.2GHz dual-core processor (vs. the Droid 3's 1GHz dual-core processor), as well as upping the RAM from 512MB to 1GB.
The device is described as Droid RAZR-like, although it loses the Kevlar back, and has a smaller 4-inch screen (the same size as the Droid 3). The Droid 4 will have a 5-row slideout keyboard with side-lit keys. No Ice Cream Sandwich for now, as the device will ship with Gingerbread.
The battery is annoyingly non-user-replaceable, just as the Droid RAZR's is, and is 1785 mAh vs. the RAZR's 1780 mAh and the Droid 3's 1540 mAh. Of course, the Droid 3 can take extended batteries, if necessary, and LTE, at least in first-generation form, is a battery hog.
Is it worth an upgrade from a Droid 3? In our opinion, not if you've just upgraded to a Droid 3, unless you can get sans early upgrade penalty. It's sporting a first generation LTE chipset, and the second generation chipsets, coming next year, will be much more generous on battery life and take up less real estate, too.
It's even expected to grace the iPhone 5, as well, so that would mean a "cure" to the LTE battery blues (or at least better life). Quite a few folks use LTE on an "on demand" basis, because it drains the battery too much.
It also bugs us that the battery is not user-replaceable. However, if you only have a Droid 2 Global or Droid, go for it. This is the device the Droid 3 should have been (with the exception of a non-user replaceable battery, our pet peeve).
