In today's world wherein nearly every smartphone is multifunctional, where users can indulge in games, surf the internet, and take photos all day, it is no longer a surprise if the phone ends up drained by the end of the day. If you think you are an exhaustive phone user, below is your guide in finding the best smartphone that will fill your needs.

The latest LG G3 is full of great things. From an expert's point of view, the smartphone is truly revolutionary as it outpaces and outclasses its competitors.

While there is no denying that fact, there are some parts of the LG G3 that is not as good as its rivals. One of them is the battery. The LG G3 might be equipped with a huge 3000mAh battery but no thanks to its QHD screen, the power consumption is at a whole new level.

Putting the Samsung Galaxy S5, HTC One M8 and the Sony Xperia Z2 together with the G3, it is disappointing to say that LG's smartphone is the worst when it comes to power efficiency. A test was conducted to see which of the four offered the best battery life and Sony triumph against all.

In the test, the phones were put together to run a script on a continuous basis. The G3 lasted for 6hours and 14 minutes. This is followed by the One M8 at 7hrs 12mins, the Galaxy S5 at 7hrs 38mins and the Xperia Z2 at 8hrs 10mins.

On the bright side of things, it only takes the G3 120minutes to get fully charged again. The Z2 requires 212minutes which is almost double the time of the G3.

All in all, power is an important aspect of a smartphone. Hence, Sony wins as Xperia Z2 is the most power efficient smartphone in the market today.
