If you are interested in what other forum members have to say there were several threads on the subject over the past few weeks. Search for "Battery Guru". Also the app's author is very active here and you can find many gems of wisdom from the man himself.
Your high wattage is almost certainly due to your backlight setting. Turn automatic dimming off, and then turn the brightness down as low as you can and stil use the screen. Wait for Guru to update and your power should drop. You might also check your App behavior, make sure it isn't set to showcase
can you tell me your consumptions with only the browser and this page opened? mine reads 3w and im not even running any other apps
That is a bit high, I think, but there are other factors to consider. Backlight is the main place to start, as noted, but remember that there's a light sensor and the brightness will be cranked up with no clear indication if you're in bright light (e.g. sunlight).
There also seems to be some bug with GPS and maybe some other service, where consumption can increase by about 0.3W even in standby after it's been used for a while... intermittent problem. To eliminate that possibility, restart the tablet and do the measurements after the reboot, before running any map/GPS/location-aware apps.
Also turn off BT/bridge to remove that factor.
I'm between 2.3W and 2.4W under similar conditions, and that's typical.
