Abstract—Despite of all the advances in smartphone technology
in recent years, smartphones still remain limited by
their battery life. Unlike other power hungry components in a
smartphone, the cellular data and Wi-Fi interfaces often continue
to be used even when the phone is in its idle state in order to
accommodate background (necessary or unnecessary) data traffic
produced by some applications. In addition, bad reception has
been proven to greatly increase energy consumed by the radio,
which happens frequently when smartphone users are inside
buildings. In this paper, we present a Short message service
Push based Service (SPS) system to save unnecessary power
consumption when smartphones are in idle state, especially in
bad reception areas. First, SPS disables a smartphone’s data
interfaces whenever the phone is in idle state. Second, to preserve
the real-time notification functionality required by some apps,
such as new email arrivals and social media updates, when a
notification is needed, a push server will deliver a wakeup text
message to the phone (which does not rely on data interfaces),
and then SPS enables the phone’s data interfaces to connect to the
corresponding server to retrieve notification data via the normal
data network. Once the notification data has been retrieved, SPS
will disable the data interfaces again if the phone is still in idle
state. We have developed a complete SPS prototype for Android
smartphones. Our experiments show that SPS consumes less
energy than the current approaches. In areas with bad reception,
the SPS prototype can double the battery life of a smartphone.
