Sony Ericsson released an Xperia X10 support video earlier this week to give some tips to extend battery performance. The timing of the video is somewhat curious, being released 18 months into the phone’s cycle. Most people reading this will already know about most of the tips and we covered much of this and more in an article back in April 2010. Most of what was said then is still relevant now. See the video after the break or click here for our own tips on extending battery performance.
