Practically everyone has a smartphone these days. Life would indeed be pretty inconvenient without our smartphones. We have all experienced frustrating moments when our phones run out of battery at the most inconvenient of times. 

Our phone experience would be so much better if we could go about our day without worrying about when we would need to charge up our phones. For this reason, one of the factors in choosing a phone is its battery life. 

However, having a big battery might not be the answer. Display screen brightness, certain apps and background services and even spotty service will drain your phone’s battery very quickly. Here we list the best battery life phones for 2020.
