For people who depend on their phones a little too much day and night, BlackBerry may have just addressed a very big issue by breaking off from the trend towards batteries which are built-in and also by punching in some of its own technologies.
People tend to look for a killer feature every time a new device comes out. These features probably predict the life of that particular device in this world of competition. It is not necessary for all devices to take up this challenge. If you look at iPhone 5, it may have features that, at most, may match up to or fall short of the competition. But the new BlackBerry 10 does have a killer feature. It is probably the sharpest killer feature that is going to be available in the smartphones currently. BlackBerry 10 will have the potential for unlimited battery life.
People nowadays will overlook the compelling features of good display, a fast network or the size of a screen. But, if the battery is weak and wears down fast, everything else amounts to little. The present generation smartphones have sealed-in batteries that are not easily swappable and they are getting smaller by the day. Manufacturers are making them thinner with each new model. But most of the new phones are not able to make it by the end of the day with their battery life strength.
BlackBerry 10 will offer you a replaceable battery. It also has an external option for charging. It will be in the form of a case that holds a spare battery for it to be charged alongside the main device. It will be plugged into the device and you can continue to work without the need for rebooting or replacing the battery. In other words, you probably will get almost unlimited life with the phone battery.
