Getting Mobile Device Context Parameters Using Javascript

Question

Is there any way through which one can get Mobile Device Context parameters like Battery level, Processor speed, Network Bandwidth etc through Javascript. I am working on a Mobile Analytic tool and need these parameters to process and present solution in a UI considering these fields.

Support for the HTML5 Battery Status API is limited (Firefox and Chrome). See this recent tutorial on SitePoint. http://www.sitepoint.com/html5-battery-status-api/

Here's another article from SitePoint re: the Network Information API. That also has limited support (Firefox and Chrome). http://www.sitepoint.com/use-network-information-api-improve-responsive-websites/

I am unaware of any accurate, cross-browser method to determine processor/hardware information via JavaScript.
