Selecting and serving a content item based on device state data of a device

A system configured to display a content item on a mobile device, the system comprising:

• one or more server data processors of at least one server;
• and a computer-readable storage device storing instructions that, when executed by the one or more server data processors, cause the one or more server data processors to:
• receive a request for a content item to be displayed on a display of the mobile device, data indicative of a charging state of an a battery of the mobile device, and at least one of a signal strength of the mobile device or a charging state of the mobile device;
• identify, from among a plurality of candidate content items and responsive to the request for a content item, a first content item and a second content item, the first content item associated with a first energy consumption level corresponding to a first energy amount consumed to display the first content item, the second content item associated with a second energy consumption level, the first energy amount higher than the second energy amount;
• select the first content item responsive to the charging state of the battery of the mobile device;
• and
• provide the first content item to the mobile device to display on the display of the mobile device.

A non-transitory computer-readable storage medium having instructions that, when executed by one or more server data processors of at least one server, cause the one or more server data processors of the at least one server to perform operations comprising:

• receiving, at one or more server data processors of at least one server, data indicative of a charging state of a battery of a mobile device and a request for a content item to be displayed on a display of the mobile device;
• identifying, at the one or more server data processors of the at least one server and responsive to the request for a content item, a first content item associated with a first energy consumption level corresponding to a first energy amount consumed to display the first content item and a second content item associated with a second energy consumption level, the first energy amount higher than the second energy amount;
• selecting, using the one or more server data processors of the at least one server, the first content item responsive to the charging state of the battery of the mobile device;
• and
• providing, using the one or more server data processors of the at least one server and for display at the mobile device, the first content item to the mobile device to display the first content item on the display of the mobile device.
