Editing SD card (section)

===Power consumption===
The power consumption of SD cards varies by its speed mode, manufacturer and model.{{citation needed|date=September 2023}}

During transfer it may be in the range of 66–330&nbsp;mW (20–100&nbsp;mA at a supply voltage of 3.3&nbsp;V). Specifications from [[TwinMOS|TwinMOS Technologies]] list a maximum of 149&nbsp;mW (45&nbsp;mA) during transfer. Toshiba lists 264–330&nbsp;mW (80–100&nbsp;mA).<ref>{{Citation | url = http://www.toshiba-memory.com/en/micro_sd_cards.html | contribution = microSD & microSDHC Cards | publisher = Toshiba | title = Memory Solutions | access-date = 2011-02-27 | archive-date = 2013-08-18 | archive-url = https://web.archive.org/web/20130818222944/http://www.toshiba-memory.com/en/micro_sd_cards.html | url-status = dead }}</ref> Standby current is much lower, less than 0.2&nbsp;mA for one 2006 microSD card.<ref>{{Citation | url = http://www.dtt8.com/images/micro-sd%20specification.pdf | publisher = DTT | title = Micro SD specification | url-status = dead | archive-url = https://web.archive.org/web/20130207004550/http://www.dtt8.com/images/micro-sd%20specification.pdf | archive-date = 2013-02-07 }}</ref> If there is data transfer for significant periods, battery life may be reduced noticeably; for reference, the capacity of smartphone batteries is typically around 6&nbsp;Wh (Samsung Galaxy S2: 1650&nbsp;mAh @ 3.7&nbsp;V).

Modern UHS-II cards can consume up to 2.88&nbsp;W, if the host device supports bus speed mode SDR104 or UHS-II. Minimum power consumption in the case of a UHS-II host is 720&nbsp;mW.{{citation needed|date=September 2023}}
