1. A method comprising a step of determining a time interval over which a refresh device is subsequently maintainable in a self-refresh mode by an associated energy source, said interval comprising multiple charge decay and refresh cycles for the device, wherein the time interval of the determining step is determined in relation to an energy requirement value of the device obtained during device operation and an energy capacity value of the energy source. |
