Preparation for reuse

As a supplier, it is your responsibility to ensure that the following requirements are met:

Smartphones and tablets

Encrypt by default, using a random encryption key, the user data stored in the internal storage of the device.
Include a software function, that resets the device to its factory settings and erases securely by default the encryption key and generates a new one.
Record the following data from the battery management system in the system settings or another location accessible for end-users:
- Date of manufacturing of the battery.
- Date of first use of the battery after the set-up of the device by the first user.
- Number of full charge/discharge cycles (reference: rated capacity).
- Measured state of health (remaining full charge capacity relative to the rated capacity in %)

include a software function that resets the device to its factory settings and erases securely by default all personal information including but not limited to address book, text messages, pictures, videos, settings and call history.
