A method of operating a mobile telecommunications device in an energy saving mode, the mobile telecommunications device comprising a mobile relational database, the mobile relational database comprising related tables, wherein the mobile relational database is stored in a first storage of the mobile telecommunication device, wherein the mobile telecommunication device operates in a default energy consuming mode, the method comprising: - providing a second storage in the mobile telecommunication device; - providing a text processing application for accessing texts encoded in a predefined character encoding scheme; - selecting from the related tables one or more set of records, wherein records of a set of records are linked with a database key; - for each selected set of records combining the records of the set of records in a text object by: ∘ encoding the entries of said records in a concatenated alphanumeric format using the predefined character encoding scheme; and ∘ tagging the text object using the database key; - storing the text objects in the second storage and deleting the one or more set of records from the related tables; and - configuring by a control unit of the mobile telecommunications device the text processing application to access the stored text objects in the second storage to operate the mobile telecommunication device in the energy saving mode, wherein the text processing application comprises a parallel bit stream text processing application; - receiving a query including a search term; - searching using the parallel bit stream text processing application for the search term in the stored text objects; - displaying portions of the text objects that include the search term in a graphical user interface of the mobile telecommunication device to prevent usage of the scrolling function of the graphical user interface. - providing a second storage in the mobile telecommunication device; - providing a text processing application for accessing texts encoded in a predefined character encoding scheme; - selecting from the related tables one or more set of records, wherein records of a set of records are linked with a database key; - for each selected set of records combining the records of the set of records in a text object by: ∘ encoding the entries of said records in a concatenated alphanumeric format using the predefined character encoding scheme; and ∘ tagging the text object using the database key; ∘ encoding the entries of said records in a concatenated alphanumeric format using the predefined character encoding scheme; and ∘ tagging the text object using the database key; - storing the text objects in the second storage and deleting the one or more set of records from the related tables; and - configuring by a control unit of the mobile telecommunications device the text processing application to access the stored text objects in the second storage to operate the mobile telecommunication device in the energy saving mode, wherein the text processing application comprises a parallel bit stream text processing application; - receiving a query including a search term; - searching using the parallel bit stream text processing application for the search term in the stored text objects; - displaying portions of the text objects that include the search term in a graphical user interface of the mobile telecommunication device to prevent usage of the scrolling function of the graphical user interface.
