PSP Slim & Lite is a name used in the PAL territories to refer to the second generation of the PlayStation Portable handheld game console released and manufactured by Sony Computer Entertainment. The same model was called simply PlayStation Portable in Japan and North America. At E3 2007, Sony released information about a slimmer and lighter version of the PlayStation Portable. The new PSP is 33% lighter and 19% slimmer than the original PSP system.
The model numbers have changed to PSP-2000, following the previous region-based numbering scheme (cf. the PSP-1000 numbering scheme of the "old" PSP model).
It was released on August 30, 2007 in Hong Kong, on September 5, 2007 in Europe, on September 6, 2007 in North America, September 7, 2007 in South Korea and September 12, 2007 in Australia. On January 8, 2008 built-in Skype Wifi Internet phone service was added via firmware updates.
Hardware
The PSP Slim & Lite system is 19% thinner and 33% lighter than the original PSP system (reduced from 23 mm to 18.6 mm and from 280 grams [9.87 ounces] to 189 grams [6.66 ounces]). Internal changes to achieve this include the removal of a metal chassis (used to reduce damage in the event of sudden trauma to the system resulting from the user dropping the system on a hard surface). However, users have complained from generally poor hardware assembly like misaligned faceplates and loose/creaky battery covers.
Other changes include improved WLAN modules and Micro-controller, and a thinner and much brighter LCD. To target the original PSP generation's poor load times for UMD games, the internal memory (RAM and Flash ROM) was doubled from 32 MB to 64 MB, which also improved the web browser's performance.
Battery
To make the PSP slimmer, the capacity of the battery was reduced by 1/3. However, due to more efficient power usage, the run time of the PSP is still the same as the older model. Older model batteries will still work which extends the amount of playing time. However, the battery cover on the newer model does not fit over the older battery due to its bulkier size. The batteries take about one and a half hours to charge and last roughly 4.5–7 hours depending on factors such as screen brightness settings and volume levels.
In mid-December 2007, Sony released the PSP Extended Life Battery Kit, which includes a 2200 MAh battery with a battery cover that fits over the bulkier battery included; initially only available in North America.[citation needed] The kit comes with two new battery covers, one black and one silver.
In March 2008 the Extended Battery Kit was released in Japan. However, unlike North America the batteries are sold individually with one specific cover.
There are three separate kits, one with the black cover, one with the silver cover and one with the white cover. This means that North American Star Wars PSP owners, whose PSPs were in black and silver colors, can now get the Extended Battery Kit with color matching cover by importing the White Extended battery kit over the Internet[citation needed]. This would also resolve some users discontent with the Darth Vader silk screen, since the Japanese white kit comes with a plain white cover[citation needed].
External appearance, inputs and outputs
The PSP Slim & Lite has a new gloss finish. The serial port was also modified in order to accommodate a new video-out feature (while rendering older PSP remote controls incompatible). PSP games will only output to external monitors or TVs in progressive scan mode, so televisions incapable of supporting progressive scan will not display PSP games. Non-game video outputs fine in either progressive or interlaced mode. USB charging was made possible
(the PSP Slim will only charge while it is in "USB mode". It cannot be charged via USB when playing a game). However, there are unofficial USB charge plug-in downloads for charging the PSP with a USB without the need for being in USB mode. The D-Pad was raised in response to complaints of poor performance, while buttons offer improved responsiveness, confirmed in the GameSpot "hands-on" review: "several GameSpot editors have noticed that the d-pad and buttons on the new PSP provide a little more tactile feedback for a better overall feel."
A new simpler and more compact UMD loading tray design was developed, in which the tray swivels out instead of opening up completely, while the Wi-Fi switch was moved to the top of the PSP. To address many consumer complaints about the Memory Stick door breaking off the old PSP, the Memory Stick door has been relocated and redesigned. The speakers were repositioned on the front of the PSP near the top of its screen. The infra-red port was also removed because it offered no use to the original PSP generation other than in homebrew applications. Its analog stick was also redesigned to be more flexible and is not removable without opening the PSP. The air vent at the top of the original was also removed.
