Core Insights - The charging speed of Android flagship phones has reached over 100W, with some models like Realme's 320W fast charging capable of fully charging in under 5 minutes, while competitors like Apple and Samsung use lower power levels, such as 25W, but the actual charging speed difference is minimal [1][2] Group 1: Charging Technology - Fast charging wattage refers to "peak power" rather than "average power" throughout the charging process, meaning that while a phone may support 100W charging initially, it will drop significantly after a short period due to battery limitations [1][2] - The charging process follows a "three-stage" pattern: constant current phase (high power when battery is low), transition phase (power decreases to prevent overheating), and trickle charge phase (slow charging to protect battery life) [1][2] Group 2: Market Dynamics - High-power fast charging has become a competitive battleground among manufacturers, with the impressive peak power figures often not reflecting the actual user experience, as sustained high-speed charging is limited [2][4] - Apple and Samsung prefer a conservative approach to charging technology, focusing on stability and reliability to protect their brand image, as safety issues could lead to significant reputational damage [4] - Reports suggest that Apple and Samsung do not see a significant sales boost from higher charging speeds, as existing solutions meet most users' needs, and increasing power would require costly design and component changes [4]
