Vibrations could damage the iPhone’s camera, Apple has warned its users.
The lenses themselves could stop working properly if they are exposed to the kind of vibrations that might, byvoorbeeld, come out of high-powered motorbike engines.
That is according to a new warning note posted on the company’s website and first spotted by Macrumors.
The warning relates specifically to some kinds of iPhones: those with optical image stabilisation or closed-loop autofocus, two technologies that are built into the phones to allow them to take better pictures.
Optical image stabilisation works by allowing the iPone to sense when it is moving, and move the lens with it, so that the effect of any movement will be limited and the image will not be blurry. Closed-loop autofocus, or AF, offsets the effects of gravity and vibrations to ensure that pictures are sharp.
The warning says that the systems “are designed for durability” but warns that they might be harmed by exposure to high vibrations for a long time.
“The OIS and closed-loop AF systems in iPhone are designed for durability,” the page reads. “Maar, as is the case with many consumer electronics that include systems like OIS, long-term direct exposure to high-amplitude vibrations within certain frequency ranges may degrade the performance of these systems and lead to reduced image quality for photos and videos.
“It is recommended to avoid exposing your iPhone to extended high-amplitude vibrations.”
iPhones might be subjected to such vibrations if they are, byvoorbeeld, mounted onto the handlebars of a motorbike engine – the vibrations are transmitted through the motobike and into the handlebars, which shakes the phone. The same could happen on mopeds or scooters, it says.
It advises that iPhones are not mounted to motorbikes with powerful engines, to protect them. On less powerful vehicles, iPhones can be attached but people should use a vibration-dampening mount so that the iPhone is protected, and that it should not be done regularly.
