Mobile devices focus on battery life over Wi-Fi performance by minimizing probing and scanning. This results in poor handovers between access points and inability to find better signals. The document discusses ways to improve this through supporting features like 802.11k neighbor reports, adjusting power save modes, and promoting use of the 5GHz band and DFS channels. Authentication methods like Passpoint are starting to be supported but cellular networks have not widely deployed compatible networks. Location services show promise but may become proprietary without open standards and APIs.
