During transfer it may be in the range of 66–330mW (20–100mA at a supply voltage of 3.3V). Specifications from TwinMOS Technologies list a maximum of 149mW (45mA) during transfer. Toshiba lists 264–330mW (80–100mA). [163] Standby current is much lower, less than 0.2mA for one 2006 microSD card. [164] If there is data transfer for significant periods, battery life may be reduced noticeably; for reference, the capacity of smartphone batteries is typically around 6Wh (Samsung Galaxy S2: 1650mAh @ 3.7V).
