Why Do Phone Makers Prefer Qi?
Phone makers embraced Qi over alternative standards for a handful of different reasons. The first, and probably most important, is that Qi had a significant head start.
Since the Qi standard was initially published in 2010, chipmakers were able to design chips that would essentially act as a shortcut for charging station manufacturers and phone makers.Using these off the shelf components, phone manufacturers were able to implement wireless charging in a relatively painless and cost-effective manner without spending a lot of their own resources on research and development.
This availability of off-the-shelf chips and other components sparked early adoption by Android device manufacturers like Nokia, LG, and HTC in 2012.
This further spurred others to adopt the Qi standard, and within the next few years, nearly every major Android phone manufacturer had built Qi wireless charging into its flagship phone.
In addition to simply getting to market first, the inductive charging used by Qi is also more energy efficient than resonant charging used by competitors, and the components are smaller. That means inductive Qi chargers can be less bulky and take up less space.
In the 1.2 Qi standard, resonant charging was also added to the specification. This made Qi the only standard with specifications for both inductive and resonant charging, which helped phone manufacturers in terms of backward compatibility.
