Rumors involving Apple's new wearable continue, with the latest focusing on the life of the Apple Watch's battery.

Sources say the Cupertino, Calif.-based company wants the smartwatch to provide 2.5 hours of "heavy" application use, 3.5 hours of standard application use and four hours of fitness tracking use, according to 9 to 5 Mac. Apple was also said to have been aiming for 19 hours for the battery life, but this goal is not expected to be met in the first version.

Features of the watch include the Apple S1 chip, which performs just as well as the Apple A5 processor in the current iPod touch, and a Retina-class color display that can update at 60 frames per second.

People familiar with the watch's development added that the gadget's creators originally hoped it would run for a longer period of time, but the desire to increase the battery life played a role in the watch's launch being pushed from late 2014 to early 2015, TechCrunch reported.

The Apple Watch is expected to maintain a popular fanbase even if it is unsuccessful in reaching the desired life due to its design for occasional use and short periods rather than long sessions.

Apple plans on making the watch available in three versions: the stainless steel standard version, the aluminum and plastic Apple Watch Sport and the Apple Watch Edition, 9 to 5 Mac reported. Whether or not the watch's battery will live up to Apple's expectations will be revealed in the product's launch, which is slated for March.
