turn off wifi gps etc. when screen is locked

[v1nsai]

I've found a lot of posts asking the opposite of this question (how to keep wifi or gps enabled when screen is locked) but I'm having a problem with all these things staying running when I don't need them and nuking my battery.

I bought this phone from ebay and it was already rooted so there may be mods on here causing this, it's my first android phone so I don't really know where to look.

I'm using the end call button to put it to sleep, maybe I'm just putting it to sleep wrong? Any help appreciated, I just want everything to go to sleep when I put my phone to sleep

I think that the wifi is being kept on when I don't have a cell signal, maybe so that if I were using gtalk I would be able to get calls. That's just a theory though.
