Battery charge aware communications

A method comprising:

• receiving, at a client device, a user selection of a content item for presentation, the content item having a set of content sections;
• determining, at the client device, that a current remaining battery power of the client device is below a predetermined threshold;
• in response to determining that the current remaining battery power of the client device is below the predetermined threshold, creating, at the client device, a content request for the content item that indicates the current remaining battery power of the client device;
• transmitting, from the client device, the content request to a server that hosts the content item;
• receiving, at the client device, from the server, a response comprising only a first subset of the set of content sections of the content item selected by the server based on the current remaining battery power of the client device indicated in the content request, the first subset of the set of content sections being identified by the server as core content sections of the content item, the response excluding a second subset of the set of content sections of the content item;
• and
• displaying, on a display of the client device, only the first subset of the set of content sections.

A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of a device, cause the device to perform operations comprising:

• receiving a user selection of a content item for presentation, the content item having a set of content sections;
• determining that a current remaining battery power of the device is below a predetermined threshold;
• in response to determining that the current remaining battery power of the device is below the predetermined threshold, creating a content request for the content item that indicates the current remaining battery power of the device;
• transmitting the content request to a server that hosts the content item;
• receiving, from the server, a response comprising only a first subset of the set of content sections of the content item selected by the server based on the current remaining battery power of the device indicated in the content request, the first subset of the set of content sections being identified by the server as core content sections of the content item, the response excluding a second subset of the set of content sections of the content item;
• and
• displaying, on a display of the device, only the first subset of the set of content sections.
