Older Android devices primarily utilized chargers featuring a connector known as Micro-USB. This connection type served as the standard for data transfer and power delivery for a significant period, preceding the widespread adoption of USB-C. As an example, many smartphones and tablets manufactured before 2016 relied on Micro-USB for charging.
The prevalence of Micro-USB provided a degree of standardization across various devices, simplifying the charging process for consumers. Its compact size also made it suitable for mobile devices. However, the design was less durable and lacked the reversible nature of newer connection types, leading to potential wear and tear over time. Furthermore, Micro-USB’s data transfer and power delivery capabilities are slower compared to modern USB-C connections.
