A common process often ascribed to memory effect is voltage depression. In this case, the output voltage of the battery drops more quickly than normal as it is used, even though the total capacity remains almost the same. In modern electronic equipment that monitors the voltage to indicate battery charge, the battery appears to be draining very quickly. To the user, it appears the battery is not holding its full charge, which seems similar to memory effect. This is a common problem with high-load devices such as digital cameras and cell phones.
