Help how do you delete downloaded skins?

[misssunshine]

I downloaded a skin for my phone and the next day my phone has been dying twice as fast. I don't if its because of the skin or not but I've had the htc desire z for about 4 months and it was fine till I downloaded the skin. Any help??

If it has a moving background it will be draining your battery a little.
Just change the skin.
You can go into settings>battery to see how much 'display' is using your battery, or download 'battery widget' for quick access.
