Battery life for a portable networked client device is preserved by providing a web page content web server with a set of non-advertisement web objects for a web page, the web page containing at least one inclusion method to one or more advertisement objects stored on an advertisement server separate from the non-advertisement web objects, by receiving by the web server a battery condition and a page request for the web page from a networked client device, and, responsive to the battery condition being low, by transmitting the non-advertisement web objects from the web page content web server to the networked client device, but avoiding incremental battery energy consumption of the networked client device normally required to execute, process, or display the advertisement objects by restricting download of the advertisement objects.
