“Woe is me” to all who bought the Motorola Droid Razr just a few blinks ago only to sigh at news of the release of the Droid Razr Maxx. If only they had waited. But how could they ever have known that the Razr Maxx, king of battery life was on its way? Already the Razr Maxx is being hailed as the best Android Smartphone mostly because battery life matters. It means more hours spent un-tethered from the dreaded, universal umbilical cord to a power source. Okay, so the Maxx is also fast, with a fantastic eight-megapixel, rear-facing camera, a docking mechanism, and, it’s cute. One problem experienced by testers is in situations of weak 4G signal. Even as a new batch of cities is getting LTD coverage, chances are you may find yourself at the edge of such a coverage area once in a while. When that happens, the phone should switch to 3G coverage but users have experienced a level of glitchiness with that. So how do you test the battery life of a phone? Back in the day, one might have put it in the hands of a teenager, but with the advent of texting, they don’t talk on their phones anymore. Instead, tech journalist Walt Mossberg had an interesting method – as described in the Wall Street Journal: “To simulate my end of the conversation, I placed the Maxx next to a laptop playing a repeating loop of famous speeches. To simulate the other end, I dialed into a special test number Motorola has that features a spoken voice on a similar repeating loop. Ignoring the company’s test suggestions, I kept power-draining functions such as Wi-Fi, 4G and Bluetooth running during the test, because I don’t think people turn those off when they make a call. Still, the call lasted 20 hours, 11 minutes.” The screen was dark for most of the call. There you have it – amazing battery life.
