Apple introduced this charging chime with iOS 6 in 2012, during the era of the iPhone 5 and the skeuomorphic interface. The sound played system-wide whenever a compatible iPhone, iPad or iPod touch connected to power. After Apple redesigned iOS 7 with flatter visuals and tweaked system sounds, the older chime became a marker of early 2010s tech. It resurfaced in nostalgia compilations, tech-history TikToks and meme edits contrasting old and new Apple, where its soft tone instantly signals a throwback.
