Default Has anyone replaced the battery?

Hi,

If anyone has had a go at replacing the battery, I'm interested to hear your experiences. I've had my nexus for just over a year I've noticed that it's been draining a lot quicker than when I first got it. It used to be very solid and I could get a day out of it quite easily. Brand new batteries go for around 20 so I thought why not?

I've ready a few guides on how to do this. The hardest part seems to be prying it away from the advesive holding it to to the casing. If anyone had managed to do this:

1) Was is difficult?
2) Did you replace the adhesive when putting the new battery in?

Cheers!
