Death
The fear of death, clinically termed thanatophobia, represents one of humanity's most primal anxieties. Philosophers from Epicurus to Heidegger have dedicated careers to addressing this fear, with limited success. The terror industry surrounding death generates billions annually in life insurance, health products, and religious observance.
Neurological research indicates that death anxiety activates the amygdala in ways that few other stimuli can match. Entire civilisations have been constructed around managing this particular fear.

iPhone-related fear manifests primarily as nomophobia (no-mobile-phone phobia), now recognised as a genuine psychological condition affecting an estimated 66% of adults. The anxiety of a dying battery at 3% can trigger physiological stress responses comparable to minor threats.
Additional fears include the dreaded shattered screen, unexpected obsolescence announcements, and the existential horror of discovering one's model is no longer supported. These fears, while genuine, rarely inspire philosophical treatises or religious systems.
