Status of the Document


This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.

A minor but substantive change has been made to the Battery Status API since the W3C Proposed Recommendation of March 2016 (diff), with the association of the Battery Manager promise to the Navigator object rather than the browsing context. In addition, concerns about possible privacy-invasive usage of the Battery Status API have been raised, which the Working Group intends to review to determine if additional mitigation strategies are needed. This specification is thus returning to Candidate Recommendation status.

The updated implementation report of the API shows all features have been implemented by two independent deployed browsers, meeting the primary CR exit criteria, so the Working Group intends to proceed to Proposed Recommendation once the substantive change and the privacy concerns have been sufficiently reviewed, no sooner than 01 September 2016.

This document was published by the Device and Sensors Working Group as a Candidate Recommendation. This document is intended to become a W3C Recommendation. If you wish to make comments regarding this document, please send them to public-device-apis@w3.org (subscribe, archives). W3C publishes a Candidate Recommendation to indicate that the document is believed to be stable and to encourage implementation by the developer community. This Candidate Recommendation is expected to advance to Proposed Recommendation no earlier than 01 September 2016. All comments are welcome.

Publication as a Candidate Recommendation does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
