The increased number of functions in smartphones give users a plethora of modern communication methods. Some have expressed a belief that the growing number of functions may eventually limit the popularity of SMS, which is still the dominant app on today's mobile devices. But, most of these new applications can be far more detrimental to battery life than sending and receiving SMS messages.

According to a number of news sources, the iPhone 4S is one of the more egregious offenders of poor battery performance.

"Not surprisingly, owners of the iPhone 4S complained about poor battery life, a much-discussed and somwhat controversial issue that was mentioned in 45 percent of the complaints about Apple's newest smartphone," writes Bill Snyder in a blog.

Studies show that many users will attempt to use various communication applications that will eat up bandwidth and, in turn, drain battery life. In the case of the iPhone 4S and its iOS 5 operating system, the use of iMessage, Apple's text communication system run on the SMS application, can hurt the battery more than traditional texting.

An article in USA Today suggests that turning off mobile data and relying on text messaging to communicate may be the best way to preserve battery life. Since most SMS text messages take up only 140 bytes, texting will not have as severe an effect on bandwidth as any other communication method.

With the amount of time people spend on their smartphones these days, especially out of the house and in social situations, battery life is of the utmost importance. Users may be more willing to stick with texting if it means having a longer lasting battery. Marketers should take advantage of the immense number of texters by implementing an SMS marketing strategy.
