The present invention introduces a method for saving power in battery limited devices. The invention handles profile properties, which may e.g. be User Interface activity, Bluetooth connection success, email fetch success or WLAN connection success. A value of the property is saved into a memory, e.g. once an hour for the whole calendar week, thus forming a trend value which is regularly updated. Certain behavior patterns may then be seen. When changes in the trend occur with different users or as differences compared to a usual behavior in a calendar week, for instance, the characteristics of the device are altered accordingly in order to minimize power usage.
