How long does an iPad battery charge last?
Apple says “up to 10 hours” of WiFi web surfing, watching video, or listening to music. Apple CEO Steve Jobs told an interviewer that playing music with the screen off, iPad lasts about 140 hours (nearly 6 days). Reviewers to whom Apple granted early access to hardware report that iPad’s battery life is even better than claimed, getting 11 to 12 hours of video playback at default brightness (50%).
