Recently, the subject of "batteries with health plummeting to 0%" has ignited a flurry of intense discussions, as numerous Apple phone users have come forward to share their experiences with battery usage. Certain users have reported that their iPhone 6s necessitated constant charging during use once the battery level dipped to a mere 13%. Meanwhile, other users have posted the cycle records of their two-year-old batteries, eagerly awaiting professional assessments. In response, a customer service representative from the official Apple Store flagship outlet clarified that Apple batteries are engineered to retain a health level of at least 80% after undergoing 1000 charge cycles, a benchmark deemed normal. Theoretically, it is possible for the battery health level to descend to 0%, though such occurrences are exceedingly rare in practice. Apple has officially declared that iPhone batteries possess a finite lifespan, and their one-year warranty encompasses service for batteries exhibiting defects.
