Motorola's latest Droid 4 packs the LTE radio the Droid 3 should have had, along with a few other upgrades along the way, while the Droid RAZR MAXX promises amazing battery life.

LAS VEGASAt CES 2012, Motorola and Verizon Wireless have launched the Motorola Droid 4 and the Droid RAZR MAXX, two 4G LTE-powered smartphones for Verizon's network.

The two companies are billing the Droid 4 as the thinnest 4G LTE QWERTY smartphone on the market4G LTE and QWERTY being two things that usually lead to thicker phones. The Droid 4 measures 5 by 2.7 by 0.5 inches (HWD) and weighs 6.3 ounces. That's no , but it'll certainly do given what's under the hood. The new version looks a little softer and classier than the . In addition to the five-row physical keyboard, which features sharp-looking, edge-lit keys, the Droid 4 also includes a 1.2GHz dual-core processor (bumped from the Droid 3's 1GHz)and 1GB RAM.

The 4-inch qHD (540-by-960-pixel) display features "scratch- and scrape-resistant" glass, but is otherwise similar to the Droid 3's panel. Motorola says the entire Droid 4 is enclosed in a water-repellant nanocoating as well. There's still an 8-megapixel camera on board with 1080p video recording, plus 16GB internal storage, a microSD memory card slot, and a useful mirroring mode to throw images or video on a living room or hotel HDTV.

One annoying downside: The Droid 4 ships with Android 2.3.5 (Gingerbread), instead of . Motorola is promising an upgrade to ICS in the second quarter of 2012, but we're moving past the point where at least high-end phones should come preloaded with Android 4.0.

As a Motorola Android phone, the Droid 4 is another device that works with Motorola's increasingly large array of convertible accessories, including the 10.1-inch Lapdock 100, the 14-inch Lapdock 500 Pro, the Vehicle Navigation Dock, and the HD Docking Station, plus Motorola's Webtop mode, which runs a desktop version of Mozilla Firefox and sports task automation features. The keyboarded Droid 4 also keeps up Motorola's business end of the equation, with support for government-grade FIPS 140-2 encryption for data security and a Citrix Receiver for Android client preloaded. It also sports a 4G LTE mobile hotspot mode that works with up to eight devices simultaneously with the appropriate Verizon Wireless plan.

All told, the sharp-looking Droid 4 gives the Droid3 the LTE radio it should have had, but is now stuck on an OS that the world is already moving away from, at least for a few monthspresumably thanks to Motorola's relatively heavy UI layer and all that Webtop mode stuff, it has to move over to ICS.

Motorola also announced the Droid RAZR MAXX, a new version of the Droid RAZR that, according to Verizon Wireless, offers an astounding 21 hours of continuous talk time on a single chargeand yet is still just nine millimeters (0.35 inches) thick, or only 0.07 inches thicker than the regular Droid RAZR. This device will also ship with Android 2.3.5, and is also set for an upgrade to Android 4.0 (Ice Cream Sandwich) within the second quarter.

Otherwise, the Droid RAZR MAXX appears the same as the existing Droid RAZR, although that battery life figure is one heck of an upgrade if it turns out to be true. Remember, the main issue here is LTE power consumption, not talk time. The regular Droid RAZR lasted just 3 hours 40 minutes when streaming data over LTE, even though it scored an impressive 8:42 in continuous talk time. Could the Droid RAZR MAXX nudge up against the 10 hour mark in LTE data streaming? Rest assured we will test one as soon as possible to find out.

Motorola says the Droid 4 and Droid RAZR MAXX won't hit stores until sometime "in the coming weeks," and has yet to release pricing information for the Droid 4; it says the Droid RAZR MAXX will be available for $299.99 (list) with a two-year contract, or $100 more than the regular Droid RAZR.
