thop said:I'd say it's probably 2-6h, depending on the game and settings (volume, headphone/speaker, screen brightness, wifi). And we don't know what games SONY tested with either. If they used one of the three majong games that are being released they probably only had to clock that thing at 50mhz. With GT4 it might look different.

Kutaragi comments raise fresh concerns over PSP battery
Rob Fahey 14:51 01/11/2004
Battery life will eventually be good, but what of first-generation machines?
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.
The SCE boss was adamant, however, that the battery life problem would be solved in future - telling the interviewer that "in the future, we'd like a single charge to last for a flight between Narita [Tokyo] and New York" - a fourteen hour trip.
He cited the Sony Walkman as an example of battery technology progress, pointing out that the device had started off with an exceptionally short battery life. However, he stopped short of saying that the company plans to upgrade the battery technology in future revisions of the PSP, instead focusing on the possibility that developers will find ways to optimise their games to use the battery life more efficiently.
The implication is clear, however, and Kutaragi's comments will undoubtedly be taken as a tacit admission that there is a problem with the PSP's battery life - and that the firm may be hoping to fix this in a later revision of the hardware.
Whether this problem is likely to scare off early adopters or not is a major question - but Sony is certainly being conservative in its shipment estimates for the device. Reports today indicating that the company expects to ship three million units of the device in its financial year, compared with Nintendo's projection of four million units of the similarly-priced Nintendo DS console, citing this as the ceiling of its production capacity for the system.

GI.BIZ has a different translation/interpretation of the same conference with Kutaragi that GS and IGN already reported on at the end of last week. So who's got the most faithful interpretation?

Finally, Kutaragi touched on the PSP's rechargeable battery, which is purported to last between four to six hours--on average--for games, and up to four to five hours for movies.
"The battery consumption changes depending on the memory and processor usage, aside from disk access," he said. "It'll run for a long time when playing puzzle games but shorter when playing Ridge Racer, for example. Using the wireless LAN also affects the battery consumption […] I think that there's still some room left for power-consumption improvement through software."
IGN - http://psp.ign.com/articles/561/561952p1.html
Continuing on the topic of battery, he offers: "By extending the amount of battery volume, we were able to create something with very good specifications. However, based on memory and processor use, the amount of power use changes. A puzzle game will offer lengthy time, but Ridge Racer will perhaps offer less than that. Using wireless LAN will have a great effect on how long the battery lasts. However, by making adjustments on the programming side of things, we would like to make it so that for whatever game you play, the announced value is an average." This seems to suggest that SCE is telling developers to hold back on pushing the system to its limits in the interest of maintaining the battery time promise.
The IGN and GS translations seem to suggest that his comments on getting more or less battery life based on the game were independent of any direct relation to the officially published battery life estimates from last week.
Sorry your concern is based on an article based on a false translation

PSP screen is made by Sharp, they make pretty good transflective LCD screens.
