If mobile devices had unlimited, never ending power supplies… that would make me shat my pants. Unfortunately (fortunately?), there is no such thing as an unlimited, never ending power supply for a mobile device (yet). However, Motorola Droid Razr MAXX HD comes close… or at least closer than any other smartphone, to date.
Motorola Droid Razr MAXX HD comes with a massive 3300 mAh Li lon Polymer battery. Motorola claims this puppy provides 32 hours of “performance” or 23 hours of talk time on a single, full charge. AllThingsD put that claim to the test and the results are impressive.
In four informal tests by Bonnie Cha of AllThingsD, Motorola  Droid Razr MAXX HD
- Lasted 22 hours of continuous cellular voice calls (with WiFi turned on)
- Continually played a video for 13 hours with screen at 75% brightness (which is brighter than what ‘Auto Brightness’ keeps most phones, in most situations), WiFi enabled, and e-mail sync on in the background before getting “low battery” alert
- Was alive for “a day and a half” (36 hours) of “moderate use” (e.g. email, social networking, music consumption, web browsing, the occasional YouTube video, etc.)
- Eeked out “almost 24 hours” of battery life with “power-hungry” tasks such as GPS, games, and long(er) videos
Compare the above to iPhone 5’s eight hour talk time (official Apple  estimate), Galaxy S III’s seventeen hour talk time (official Samsung  estimate), and the fact that iPhone 5 lasted nine to twelve hours of “moderate use” in another AllThingsD test. Yeah, there is no comparison: if battery life is important to you, Razr MAXX HD is your boy.
That said, if you grab a Razr MAXX HD, you aren’t necessarily sacrificing other features and functionality for battery life. Indeed, Motorola Droid Razr MAXX HD is a mid-to-high-end phone that sports 4.7-inch 720×1280 (720p) Super AMOLED HD display, 1.5 GHz dual-core processor, 1GB RAM, 32GB internal storage (with support for up to 26GB microSD), 8 MP back camera, 1.3 MP front camera, Android 4.0 Ice Cream Sandwich, 4G LTE, and more. Sure it doesn’t have Jelly Bean (doesn’t Google  own Motorola — why the hell don’t Moto devices have Jelly Bean?!) and may be “only” dual-core, but if you look at the phone’s battery life as the main attraction and the other features as extras, there is very little to complain about. (At least in theory — I haven’t actually used the device myself, so don’t take this as a review from dotTech.)
Unfortunately, in the United States Droid Razr MAXX HD is available only through Verizon and comes at a hefty $300 with two-year contract. There doesn’t appear to be a GSM-only version of Droid Razr MAXX HD, not even outside the United States. On the bright side, Droid Razr MAXX HD has “global roaming” so it has GSM radios built-in; if you take the phone outside the Untied States, you can use it on 2G/3G GSM networks. In the United States, however, going with Verizon (and outrageous cell phone plans) is a price you must pay for that awesome battery life.
