smartphones give us the ability to do so many things. they bring the functionality of a PC to the palm of you hand. the problem is that people think they can use smartphones as much as they use their PCs. playing games for hours, streaming audio and video all day, leaving your phone connected to the web all day to update everything and constantly talking and texting. you can do those things on a smartphone, but should you, and if you do, should you expect your phone to be able to handle it energy-wise and performance-wise? smartphones are NOT PCs. functionally-wise, maybe, but performance-wise and capability-wise not at all. many people complain about the battery life of their phones. when a smartphone is used the way its intended, most smartphones will easily go a day or two without needing a charge. however, if someone tries to use their smartphone like its a mini computer, they'll find themselves needing to charge up in the middle of the day. for those claiming to get 2 or 3 days from their battery, try streaming an entire sports game or two on your phone with your mobile data and see how long your battery lasts. those who want to play 3d games on their phone for hours and watch youtube all day better be near a power source. even the almighty battery of the droid razr maxx lasted a mere 6 hours in a 4g video streaming test. smartphones were made for the user to, for most part, use them as..well...phones, while providing some PC functionality but in NO WAY were these designed to replace you PC. we may get to that point eventually, but we have a LONG way to go.
