Is it a surprise to anyone that the Motorola DROID RAZR MAXX HD
and its 3300mAh battery beat out top handsets like the Samsung Galaxy S III
and the Apple iPhone 5
in a battery life test? In fact, the Motorola handset has a battery with a capacity nearly as much as those two high-end phones together. In case you're curious, the Apple iPhone 5 has a 1440mAh
cell and the Samsung Galaxy S III offers a 2100mAh
All Things D put the Motorola DROID RAZR MAXX HD through some fairly heavy duty testing. A continuous phone call with Wi-Fi on, the screen timed out at 30 seconds, resulted in 22 hours
of talk time, just one hour shy of Motorola's claims. Apple's estimate for talk time is 8 hours with the Samsung Galaxy S III weighing in at 17 hours.
In another test, a loop of video was played on the Motorola DROID RAZR MAXX HD with the screen brightness set at 75% and email running in the background. The phone ran for 13 hours before the low battery warning popped up. And for a more realistic test of how the battery on the phone would last under real world conditions, the phone was used moderately (described as "checking email and social networks, listening to music, browsing several Web sites and streaming a couple of YouTube videos over Verizon’s 4G LTE network") and went a day and a half before needing a recharge. Meanwhile, the WSJ's Walt Mossberg was using an Apple iPhone 5 and was able to get 9 to 12 hours
out of the battery with "mixed use".
Adding GPS use, game playing and streaming longer videos took the Motorola DROID RAZR MAXX HD down to 24 hours of battery life. You would think that this would make the device a power user's dream. but many automatically drop the model from contention because of the sealed battery. One interesting stat is that when it comes to standby times, the Samsung Galaxy S III actually bests both the Motorola DROID RAZR MAXX HD and the Apple iPhone 5. Those hours, respectively, are 770, 372 and 225.
