1. A method for estimating quality of experience, QoE, for a media stream, the method comprising:
receiving a trigger in the media stream;
creating a first window of frames in response to receiving the trigger;
receiving the first window of frames of the media stream;
determining that the media stream is being played on a portable device;
determining a battery charge percentage of the portable device;
increasing a time offset between the first window of frames and a second window of frames based on an inverse proportionality to the battery charge percentage of the portable device;
receiving the second window of frames of the media stream after the increased time offset;
measuring a plurality of metrics relating to the first and the second windows of frames;
aggregating the plurality of metrics for each window of frames;
determining a window quality of experience value based on the aggregated plurality of metrics; and
taking corrective action on the media stream based on the quality of experience value, wherein the corrective action is selected to change a streaming parameter of a server that provides the media stream.
