GoKawiilReport: Using one wireless earbud regularly leads to uneven battery wear over time
A tech advisory explains that habitually wearing only one earbud from a pair—whether for calls, lectures, or driving—causes that bud's battery to degrade faster than its twin, creating an imbalance. It recommends using transparency or ambient mode instead, which lets wearers hear their surroundings while keeping both buds in, or relying on speakerphone and car systems like Apple CarPlay for calls while driving.
