The PS Vita slim, or PCH-2000, was released by Sony in 2013, two years after the original Vita. The slim variant is 20% thinner and 15% lighter compared to the original. It has a lower cost LCD screen, an hour extra battery life and 1 gb of internal memory. Moreover, the charging jack is a micro-USB type B port compared with the odd format of the original.
As the years pass by, the batteries in these units are getting older and need to be replaced. New batteries can be bought from many online marketplaces for around $10-15. This post is a quick guide on how to replace the battery in the PS Vita slim. The procedure is rather simple and you only need a Philips screwdriver and a plastic prying tool to perform it.
