A Standby time specification is an industry standard. The only intention is to allow comparison of different mobile 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. Therefore, Standby time specification comparisons of different mobile phones can only be done in a controlled laboratory environment. When using any mobile phone in real life - ie, under circumstances for which the mobile phone is intended - the actual standby time could be considerably lower and will be strongly dependent on factors as mentioned above.
