The battery life of a cell phone is probably its most important function. You can have the most powerful, fastest, or coolest phone on the market, yet if your battery life is poor, you will only have access to your phone for a limited amount of time.
New phones are constantly being updated with the latest technology which sucks up increasing amounts of battery life. Despite this, battery life is the least improved part of the phone over the past decade. Today’s phones are coming out with very large batteries compared to previous years to provide greater battery life for talking, texting, and web surfing.
