Smart phone's internal storage capacity with product upgrades increasing smartphone currently on the market are mostly dominated 16GB and 32GB versions, but the user will find that the actual use of the phone's internal storage space is often less than the value indicated by manufacturers, and even there is not a small gap, according to Chinese regulatory investigations, more than 60% of the smartphone market, the storage capacity of both the existence of the situation to steal two pounds less, including Samsung, Apple and other big mobile phone manufacturers products are no exception.
According to field investigation, labeling 16GB storage space Apple iPhone 5 smart phone, displaying the available memory is 13.5GB, the same as the 16GB Samsung Galaxy S3 phone displays the available memory capacity of 11.25GB, marked with the manufacturer's capacity difference of 4.35GB, 16GB of 2A millet phone displays the available memory is only 10GB. The apples and millet phones are not supported memory card to expand storage space, even if the users have found that the phone can not be saved by other means insufficient to increase the phone's storage space.
To this end the company's customer service call related to Apple technical staff said, tagging internal storage capacity does not match with the actual available capacity is mainly because the mobile phone operating system, publicity and the different ways of calculating memory. While industrial production, marketing and electronic devices are based on Byte memory size calculation as a unit, but the industrial hygiene industry and manufacturers of external data is published every 1,000 Byte (10 3) into one, and the electronic equipment system is on a per 1024KB (2 10) into one, that is, binary and decimal usage variances. Although this difference seems small, but as from KB, GB continuously into the class, the error between the two have continued to increase, resulting in phone advertising space marked with the manufacturer factory inconsistent things from happening.
