GraphQL Solves REST API's Critical Data-Fetching Inefficiencies in Mobile Apps

REST APIs impose unnecessary performance costs on mobile applications by sending unused data fields (over-fetching) or requiring multiple requests for complete information (under-fetching). GraphQL eliminates these inefficiencies by allowing clients to request only required fields, significantly reducing bandwidth consumption and network latency—a core reason why engineering teams are increasingly adopting GraphQL for mobile-first architectures.
