iPhone 4 Verication Testing — Carrier Screening 179
2012-02-21
Cosmetic Protection
Prior to the start of testing a generic Mylar cling wrap should be used on each side of iPhone to
protect it from damage during the screening process. This can be purchased on rolls from local
suppliers.
Suggested size for this Mylar Cling wrap is:
Width: 2.75 inches (width of roll)
Length: 4.75 inches (spacing between each perforation)
The above dimensions will allow for some overhang to protect the buttons and bezel, but also
allow for easy removal of the wrap.
It is recommended that during product testing that cotton gloves be used to further reduce
the risk of inducing cosmetic issues within the process.
Functional Testing for Carriers
Charge Battery
1. Turn on the device by pressing and holding the On/o button until the Apple logo appears
on screen.
2. From the Home screen, check the battery level indicator in the top right corner. If the
battery indicator shows a low-battery image or is less than 50%, charge the device.
3. Plug device into a known-good Apple USB Power Adapter. Do not charge device from a
computer’s USB port. Charge time from 0 to 50% will take approx. 20 minutes. If iPhone is
extremely low on power, the display may be blank for up to 10 minutes before one of the
low-battery images appears:
Important:
• Before connecting any cable to the dock connector or the headphone jack, check the port
condition for debris, contamination, corrosion, liquid, or damage, and clean or remedy this
issue before connecting cables.
• If when charging the device, it becomes too hot, disconnect and replace the device.
