In a recent support post, Apple has issued a warning to iPhone users about the potential risks of exposing their devices to high-amplitude vibrations, particularly those generated by high-powered motorcycle engines. According to the company, such vibrations can degrade the performance of the iPhone’s camera system, leading to reduced image quality for photos and videos.
Understanding the Risks
Apple’s explanation delves into the technical aspects of how the iPhone’s camera systems work. Many iPhone models, starting from the iPhone 6 Plus and later, including the iPhone 7 and beyond, as well as the second-generation iPhone SE, are equipped with optical image stabilization (OIS) and closed-loop autofocus (AF) technologies.
OIS helps reduce image motion and blur by moving the lens according to the angle detected by the gyroscope sensor. Closed-loop AF, on the other hand, counteracts the effects of gravity and vibrations to maintain sharp focus in various modes, utilizing on-board magnetic sensors to determine the optimal lens position for compensatory motion.
While these systems are designed to be durable, prolonged exposure to high-amplitude vibrations within specific frequency ranges can potentially compromise their performance, resulting in diminished image quality for both photos and videos.
Recommendations for Motorcycle Users
Apple advises against attaching an iPhone directly to a motorcycle due to the potential transmission of vibrations through the handlebars and chassis. The company suggests that individuals planning to affix their iPhones to scooters or mopeds should consider using vibration-dampening mounts to reduce potential risks to the phone and its camera system.
It is also recommended to refrain from extended regular use of an iPhone mounted on a vehicle that generates lower-amplitude vibrations to maintain optimal performance.
The issue is not specific to iPhones, as users of other smartphone brands, such as Samsung Galaxy and Google Pixel, have reported similar camera problems when mounting their phones on bikes for extended periods.
