Nexus 7 Battery Life

How is everyone finding the Nexus 7 for battery life?

I've been using the ipad very frequently now since the ipad 2 launch day, and the battery is excellent. I mainly use for email and browsing, and it easily lasts a week, and has lasted very much longer on standby without usage.

Since the Nexus 7, i've switched. I love the smaller more portable form factor. (the ipad has now been given away to the wife to match her iphone). Im now all Android ;) And i much prefer it.

However, im finding that the battery life just isnt as good.

has anyone else found that it is generally not as good ?

i see from the specs its supposed to be around the same..

does any one have any tips or default things to switch off etc to make it last that little bit longer?
