This paper In, to our best knowledge, we are first to provide an experimental study on how
storage techniques affect
power levels in smartphones and introduce energy-efficient approaches to reduce energy consumption
.
We evaluate power degradation at several layers of block I/O, focusing on
the block layer and device driver.At each level, we investigate
, the amount of energy that can be saved,and that use
to design and implement a prototype with optimal energy savings
named SmartStorage.The system tracks the run-time I/O
pattern of a smartphone that is then matched with the closest
pattern from the benchmark table. After
having obtained the optimal parameters, it dynamically configures storage parameters
to reduce energy consumption. We evaluate our prototype
By using the 20 most popular Android applications,
and our energy-efficient approaches achieve from 23% to 52% of energy savings
compared to using the current techniques
