Hello. All the families 3DS's (two 3DS, 3DS XL, NEW 3DS, NEW 3DS XL) show the same symptom since +- 10 days: the batteries are drained in standby mode within less than a day. The units are in standby with streetpass / spotpass on. It seems as if this behavior started with the firmware update from the beginning of March 2016.

Anyone noticed the same problem?
