Gone are the days when you needed batteries with capacities larger than 5,000 mAh for your devices to last long. The recently launched Asus Zenfone Max lets you do all this with just a 4,100 mAh battery, thanks to its innovative battery technology. Asus has included an OTG cable with the Max devices, ensuring that you can use its battery as a power bank if you need to. You can choose from five different battery modes depending on usage and how much charge remains on your phone.

The 5.5 inch Zenfone 3 Max (ZC553KL) is powered by a Snapdragon 430 64-bit processor, in addition with an Adreno 505 graphics processor aimed at hardcore gamers. The device comes with a 16 MP rear and 8 MP front camera, along with an electronic image stabilisation (EIS) feature that counteracts hand movements while shooting videos. However, the 5.2 inch Zenfone 3 Max (ZC520TL) comes with a quad core processor and a Mali T720 graphics processor. The rear and front camera configurations are 13 MP and 5 MP respectively.
