They only fly on full power on take off, and climb out. It's hard on the engines to use full power too long.
TOKYO - (Reuters) - Japan Airlines Co Inc said that a Boeing 787 Dreamliner flight from Helsinki to Tokyo experienced problems with the same type of battery that caught fire in Boston in January and grounded the 787 fleet worldwide for three months. The JAL website said on Sunday that the battery on JAL flight 414 on Friday did not overheat or emit smoke, but that a cockpit indicator showed trouble with the battery connected to the plane's auxiliary power unit during the flight. "However, the voltage and electrical current were within normal range and there was no effect on the remainder of the flight," the airline added. Inspections of the battery, which was removed and replaced, were continuing. Boeing officials were not immediately available for comment.

Can you tell me what looks like an open hatch near the tail at 6:27 in this video is? Also I've seen test flight video where there's a small parachute tied to the tail. What is that about?
