A method for detecting a context of a mobile device equipped with sensors and a context detection module in which the sensors are assigned to at least two groups, each of which comprises at least one sensor, and each group is allocated a group classifier adapted to detect, in a form of a classification result, currently identified, by means of a given classifier, context of the device based on indications of the sensors belonging to the given group, characterized in that with a use of the context detection module, whereas the groups of sensors are ordered hierarchically, and the device context is detected by reading a classification result indicated by the classifier of the currently active group, wherein in case of detection of an identified context in the active group, switching on power supply of the sensors and activating classification in a group with a level higher by one level and reading the context indicated by said group's classifier, wherein based on the results of the classification indicated by the higher groups' classifiers, executing adaptation of the configuration of lower groups' classifiers.
