Speaking in an interview with Japanese site Impress PC Watch, Sony Computer Entertainment boss Ken Kutaragi has admitted that graphically intensive game will drain the PSP's battery more rapidly than the quoted figures.
"A puzzle game will last longer, but Ridge Racer will probably be shorter than that," he told the site, referring to the battery life statistics released by SCE last week - which claimed four to six hours of battery while playing games.
The figures quoted by SCE rely on playing with headphones, without using the wireless multiplayer capabilities of the device, and with screen brightness set in a specific range - leading to widespread speculation that using the full power of the system will bring the battery life down closer to the originally rumoured two hour level.
Kutaragi's comments seem to confirm that games which use the features of the console more intensively will drain the battery life faster, and are backed up by the firm's efforts to restrict developers from using features such as data streaming from disc (as used in a large number of PS2 titles) due to their high power consumption.
