|BlackBerry manufacturer, Research in Motion has refuted reports that its upcoming tablet device has a poor battery life, claiming that the reports are based on pre-production models.
An analyst at Kaufman Bros., Shaw Wu write a note last week where he cited unnamed sources as saying that the PlayBook battery lasted only a few hours. By comparison, Apple's iPad lasts around 10 hours and Samsung's Galaxy Tab offers at least six hours.
Wu added that the delayed launch for the Playbook may have been due to the battery problems.
However, in a statement to Reuters, the company said: "Any testing or observation of battery life to date by anyone outside of RIM would have been performed using pre-beta units that were built without power management implemented,"
It added that development of the battery was on schedule and its performance would be comparable to competitors.
