LG Optimus G Battery Life

The LG Optimus G was recently released in the Philippines. With a 4.7-inch 720p display it should be more power efficient than the latest 5-inch 1080p Androids. Is there merit to getting what it now a transitional model between last years flagships and todays cutting edge Android phones?

The LG Optimus G comes with a non-user replaceable 2100 mAh battery.

I will compare it to the two leaders, the Samsung Galaxy S III and the Apple iPhone 5 and the soon to be released 1080p Sony Xperia Z.

Talk Time

Sony Xperia Z - 16 hours and 3 minutes

LG Optimus G - 15 hours and 30 minutes

Samsung Galaxy S III - 10 hours and 15 minutes

Apple iPhone 5 - 8 hours and 42 minutes

The quad core Qualcomm S 4 processor on the Sony and LG seems to be very efficient in low powered tasks.

Video Playback

Apple iPhone 5 - 10 hours and 12 minutes

Samsung Galaxy S III - 9 hours and 27 minutes

LG Optimus G - 7 hours and 30 minutes

Sony Xperia Z - 5 hours and 39 minutes

The Apple iPhone with the smallest and lowest resolution displays tops this test. Samsung's Super AMOLED technology is also very efficient in video playback tests. The lower pixel density and smaller display of the LG Optimus G give it the edge over the Xperia Z.

Web Browsing

Apple iPhone 5 - 9 hours and 56 minutes

Sony Xperia Z - 6 hours and  37 minutes

Samsung Galaxy S III - 6 hours and 27 minutes

LG Optimus G - 5 hours and 15 minutes

The Apple iPhone with the smallest and lowest resolution displays tops this test again. There are a lot of merits to a smaller screen. Samsung's Super AMOLED technology is not efficient in web browsing tests which predominantly use white or light colored backgrounds, but does well enough in this test. The LG Optimus G is a rather disappointing in this test, with a smaller screen and lower resolution than the Sony Xperia Z. The Xperia Z's battery is 10% larger, but the difference does not explain the result.

Standby (with 1 hour of calls, video playback and web browsing per day)

Apple iPhone 5 - 51 hours
Samsung Galaxy S III - 50 hours
Sony Xperia Z - 48 hours
LG Optimus G - 45 hours
