Droid Razr HD

The Droid Razr HD and Razr Maxx HD were announced alongside the more compact[12] Droid Razr M on 5 September 2012. The Razr HD and M models first shipped with Android 4.0.4 (Ice Cream Sandwich). The Razr HD models were both upgraded to Android 4.1.1 (Jelly Bean) starting December 3, 2012.[13] The Razr and Razr Maxx HD both got upgrades to Android 4.1.2 (update 9.16.6) on March 18, 2013. Included were connectivity and security improvements as well as camera upgrades.[14] Earlier leaked code names include the Motorola DROID Fighter and Motorola DROID Vanquish.[15][16] In May 2014, the phone was then again updated at version 4.4.2 KitKat.

Motorola Mobility has chosen to differentiate the Droid series from other Android devices primarily by focusing on a superior battery capacity both for the standard and Maxx variants. An often compared competitor, the Samsung Galaxy SIII, has a 2100 mAh battery compared to the standard 2530 mAh Razr HD and the 3300 mAh Razr Maxx HD.[17] Motorola claims that this equates to 20% on the Razr HD and 50% longer battery life on the Razr HD Maxx. Other critical reviews have noted the durability and rugged feel when describing the DuPont Kevlar backing.[18] Additional durability is touted with a Corning Gorilla Glass display claiming to minimize scratches and an internal water-repellent nano-coating to resist liquids from affecting components.
Additionally, the Razr HD has a 4.7 inch 1,280×720 resolution Super AMOLED display with a 312 pixels per inch pixel density.[19][20] The phone has an 8-megapixel rear camera, 1.3-megapixel front-facing camera and a 1.5 GHz dual-core Snapdragon S4 ("Krait") processor with LTE and NFC. The phone has 1 GB of RAM.[21]

At the same time of launch, Motorola released a Maxx variant of the standard Droid Razr HD featuring a higher battery capacity and larger internal storage capacity. The Razr Maxx HD is equipped with a 3300 mAh Li-Ion battery, a 30% increase in capacity over the 2530 mAh battery in the standard Razr HD. Due to the battery's larger physical size, the Razr Maxx HD's overall thickness increases by 0.9 mm over the standard variant at a total thickness of 9.3 mm. Additionally, the Droid Razr Maxx HD is only available with 32 GB internal storage, double the internal storage of the standard Razr HD's 16 GB.

The Droid Razr Maxx HD is only available with a black colored bezel for the display assembly.

To promote the Droid Razr Maxx HD, a Limited Edition was made available to Verizon employees only. The Limited Edition has a few cosmetic differences; these consist of a red colored power button, red and black colored weave for the backing with the words "LIMITED EDITION" printed on it, and an individually numbered rear camera window.[22] In comparison, the consumer version has a gray colored power button that matches volume rocker color, gray and black colored weave for the backing, and no serial number on the rear camera window.

The Droid Razr HD Developer Edition[23] went on sale direct through Motorola on October 18, 2012[24] featuring an unlocked bootloader allowing the ability to flash custom ROMs onto the phone, and also providing easy root access. This device is marketed primarily to the Verizon Wireless 4G LTE network users in the United States whose bootloaders cannot be unlocked through Motorola's unlocking program, or unlocked with scripts made to unlock them. The international (non-US) Motorola Razr HD UTMS/LTE variant sold in parts of Europe, Latin America, Australia and Canada can be, however.[25]

The Droid Razr HD Developer Edition is only available with a black bezel color in the standard 2530 mAh battery configuration; there is no Droid Razr Maxx HD Developer Edition.
