Abstract—Using data from 43 users across two platforms, we
present a detailed look at smartphone traffic. We find that browsing
contributes over half of the traffic, while each of email, media, and
maps contribute roughly 10%. We also find that the overhead of
lower layer protocols is high because of small transfer sizes. For
half of the transfers that use transport-level security, header bytes
correspond to 40% of the total. We show that while packet loss
is the main factor that limits the throughput of smartphone traffic,
larger send buffers at Internet servers can improve the throughput
of a quarter of the transfers. Finally, by studying the interaction between
smartphone traffic and the radio power management policy,
we find that the power consumption of the radio can be reduced by
35% with minimal impact on the performance of packet exchanges.
