How about web browsing? Getting back to the LG Optimus 4X HD, the 4.7 inch display has a huge backlight that requires energy from some source-like the battery, of course. While not shown on the chart, the HTC One X outlasted the LG model in the web browsing test, despite the larger battery on the LG phone. The international version lasted 4 hours and 18 minutes while the AT&T variant lasted for a bit over 5 hours vs. 3 hours and 59 minutes for the LG Optimus 4X HD. And what phone won the web browsing test? The Motorola DROID RAZR MAXX, with 7 hours and 23 minutes of surfing time, led the way.
That leaves video playback. Could the larger battery on the LG Optimus 4X HD beat out the smaller one on the HTC One X when it comes to watching video? Nope. While the latter came in with a video playback time of 4 hours and 14 minutes before the battery died, the HTC One X lasted an hour and a half longer despite the smaller battery. And it is the Motorola DROID RAZR MAXX that scores the hat trick with a first place video playback time of 14 hours and 17 minutes. Battery performance like this is one of the reasons why the model has overtaken the Apple iPhone 4S to become the top selling smartphone at Verizon.
