We thought Sony's days of PR mishaps might be behind them, but it appears the platform holder are still capable of the odd mistake - marketing boss retracting previous statements made to the effect that the new 3000 model (out this autumn) will have slightly reduced battery life compared to the current model, because of its brighter screen.

Koller told the PlayStation blog: "I’d like to make a correction and clarify that the new PSP will have equivalent battery life to the current PSP, about 4 to 6 hours for games and about 4 to 5 hours for UMD videos."

He continued: "While the enhanced screen of the new PSP draws a little more power, our engineers in worked to reduce the power consumption of the overall system including its components, so you won’t have to worry about losing any time when enjoying the more vibrant visuals displayed with the new PSP."

Koller had previously suggested that 20 or 30 minutes might be cut from the system's battery life, but this is apparently not the case.
