thanks droll. It's been on overnight in power 48 mode and been fine. Don't know about the patches (speed and battery). Might leave it for a bit. Didn't make a huge difference on my n900 anhyway. Don't think the battery did anything really. The speed patch in combination with the fasterfox plugin and fooling iplayer into thinking microb was an iphone browser made iplayer videos work fine. That was the main difference there.
