Best smartphone battery life: LG G2 The newly launched G2 is a strong performer when it comes to battery life. The efficient Snapdragon 800 and 3,000 mAh battery regularly delivered 15 hours of above average use blending phone calls, maps, podcasts, and browsing. Cranking the brightness up to 100 percent can still give you over 11 hours of usage. Unless you drain the battery by spending several consistent hours of watching video, it will be difficult to have the battery drain prior to making it home.
Other features of LG G2 include a super fast Snapdragon 800 processor, a sharp 13-MP camera with optical image stabilization and some pretty nifty multitasking features. The smartphone comes with Rear Key design where the company has placed the G2's power and volume buttons on the back of the device rather than the sides. The company claims that this approach makes the 5.2-inch smartphone easier to use with one hand. The LG G2's 5.2-inch 1920 x 1080p display depicts vivid and vibrant images that are moderately bright.
