You’ve just purchased that shiny new Android smartphone and want to take advantage of all the features. One of those features is NFC or Near Field Communication. This feature allows you to share information with other, close NFC devices with a simple wave or tap. However, this feature drains your battery greatly.
This is not new news. However, more devices are coming out with this feature enabled. On some of those devices, this feature can be a little challenging to turn off. It is not always on the top of the wireless and network settings like Wi-Fi. It is under “More” on many of the newer Android phones.
Finding this setting is important, especially if you have noticed a shorter than expected battery life. After testing this feature on four handsets, two running Ice Cream Sandwich and two running Jelly Bean, the battery life was down to around 50% with no active usage other than email checking running in the background. After turning off NFC, the battery had around 90%-95% left within the same timeframe.
While this feature is a nice way to share information wirelessly, it is not ready for full primetime. If you do not see yourself using this feature, look for ways to turn it off. You should see some significant improvements in your battery life and, in some cases, to the reactive speed of your phone.
Details on how much NFC may drain your battery can be found all over the web. A simple reference is in the xda developer forums.
