Most Android smartphones today are built to offer speed and power with little, focusing on energy efficiency. To the consumers, battery life is top of the priority when they are purchasing a new smartphone.

With that in mind, The Motoring Crunch has decided to lend a helping hand by listing out the smartphone that offers the best battery life around.

For starters, there is the Philips Philips. This device is not a mainstream brand in the smartphone industry but it is built with a whopping 5,300mAh battery. The energy source on the Philips is so huge that one can easily call it a power bank instead of a smartphone. The specs are also decent which makes it a good purchase.

Then, there is the ZTE Nubia X6. The 4,250mAh battery can offer adequate power for the X6 to run for days. On the downside of things, the X6's 6.44" display is a major power sucker and the large battery won't be enough for the users.

After digging deeper, it appears that the Gionee M2 is by far the most power efficient phone to date. The 4,200mAh battery is able to keep the device on standby for a whopping 555hours. On top of that, users will enjoy 31hours of non-stop talk-time.

All in all, the Philips Philips and the Gionee M2 are the best devices out there. It is amazing how smaller brands are able to offer more battery life than the mainstream devices.
