Smartphone batteries have evolved significantly since the inception of mobile phones. The first mobile device, the Motorola DynaTAC 8000X, launched in 1983, featured a NiCad battery with only 30 minutes of talk time. In 1991, the introduction of lithium-ion batteries by Sony marked a pivotal shift, enabling longer battery life and lighter designs. The IBM Simon, released in 1994, was the first smartphone to use such technology, incorporating features like a touchscreen and email capabilities. Today, smartphones predominantly use lithium-ion or lithium-polymer batteries, which provide higher energy density and efficiency, although they face challenges like reduced capacity over time and non-replaceable designs in many models. Apple Apple's iPhones have used lithium-ion batteries since the original model launched in 2007. These batteries provide higher energy density and efficiency compared to older technologies like NiCad. iPhone batteries are designed to retain 80% of their origina
