Motorcycle enthusiasts may want to be wary of taking their iPhones along for too many rides.
Apple has published a support document warning that exposure to vibrations, such as those generated by high-powered motorcycle engines, might impact iPhone cameras. More specifically, Apple warns that long-term direct exposure to “high-amplitude vibrations within certain frequency ranges” may affect the performance of certain camera systems such as optical image stabilization (OIS) and closed-loop autofocus (AF). The result of this is reduced image quality for photos and videos.
High-power or high-volume motorcycle engines generate intense high-amplitude vibrations, which are transmitted through the chassis and handlebars. It is not recommended to attach your iPhone to motorcycles with high-power or high-volume engines due to the amplitude of the vibration in certain frequency ranges that they generate. Attaching your iPhone to vehicles with small-volume or electric engines, such as mopeds and scooters, may lead to comparatively lower-amplitude vibrations, but if you do so a vibration dampening mount is recommended to lessen the risk of damage to your iPhone and its OIS and AF systems. It is also recommended to avoid regular use for prolonged periods to further lessen the risk of damage.
OIS is available on iPhone 6 Plus, iPhone 6s Plus, and iPhone 7 and later including iPhone SE (2nd generation), while closed-loop AF is available on iPhone XS and later, including iPhone SE (2nd generation).
