Mobile phones have become an indispensable part of human life. It is no longer a device meant only for communication purpose. People are now using these for several other purposes as well. While some prefer to browse movies or stream music on the mobile phones, there are others, who use it for playing games.

When we have a smartphone with us or when we plan to buy a Smartphone, one of the most basic aspects we are all looking for is a long battery life that will last through the day at the minimum. It is indeed a pain to be travelling around with low battery and having to charge it frequently using a charger or a power bank.
