How to extract the most data via Chrome/Firefox browser on Android?

Question

I'd like to demonstrate (for a university class that I'm teaching) what you can find out about your/an android phone from a simple html-page with some java-script (i.e. Battery status, IP-Adress, etc.). Is there a project that shows all the available data on one page (no obfuscation, secrecy, etc. needed)? Note: iPhone Information is okay, too, but afaik delivers much less (reliable) data.
