I've made a simple page that attempts to simulate web browsing without you having to do anything.

It features some text, a large random image, and some javscript that creates ~3000 new lines, as well as doing some javascript computation. It should simulate average 3G behavior.

It will automatically refresh the page once every 13 seconds from the start of the page load, and is designed so that Safari does not cache it.

The strain on your 3G data cap should not be much, the HTML is only 2 kilobytes per refresh.

You should:

0) Charge your iPhone fully
1) Set auto lock to never
2) Close all background applications
3) Turn off Wifi
4) go to http://glados.cc
5) Record the current time
6) When your battery is at 50%, post here with how long it took for your 4S to drop to 50% battery during the 3G Surfing Battery Test.

Apple claims 6 hours for 3G surfing. It should take 3 hours for your battery to drop to 50%.

Make sure to post your device, and iOS version too.

My results on a iPhone 4S running 5.0.1, it took 2 hours and 20 minutes for it to drop to 50%. Kinda disappointing.

I already know mine will be similar. I gave my 4 to my son when I got my 4S. We both run iOS 5.0.1 and his lasts more than twice as long as mine, and he uses his phone constantly. I'm just hoping this 5.1 build that's coming soon does something to help.

I tested with my iPhone 4S running 5.0.1 and it took 24 minutes for a 10% drop in battery level. Extrapolating to 100% gives 4 hours of usage, which is what I usually get on 3G.

OP states,
"Apple claims 6 hours for 3G surfing. It should take 3 hours for your battery to drop to 50%."

Not accurate. The first half of battery life doesn't necessarily equate to the exact same time during the second half.
The true test would be to run the battery down to zero.

^^This...Battery consumption is weird.
