Last year, a survey was conducted about the most important feature that they want in the next iPhone. More than 1600 people took part in this survey and 75% of the people gave the vote to the ‘Longer battery life’. It is a fact that almost all the smartphone users want that their phone should have a high-resolution screen and faster processors. Along with high-resolution screens and faster processors, they also want their phones should not die at the end of the day.
