A Standby time specification is an industry standard. The only intention is to allow the comparison of different cell phones under the same circumstances. Factors including – but not limited to – network, settings, location, movement, signal strength and cell traffic strongly effect standby power consumption. Standby time specifications of different cell phones can therefore be compared only in a controlled laboratory environment. When any cell phone is used in real life – i.e., under circumstances for which the cell phone is intended – the actual standby time could be considerably lower and will be strongly dependent on the factors mentioned above.
