Network I/O

Read write/local file database

Sleep/Standby Mode

How can we do better?

• Open connection• Avoid polling and use TCP persistent connections• Avoid multiple connections

• Data• Data format• Compression

• Network Optimization• Network parameters• Connection policy

Read write/local file database

• Memory Caching• Use batch processing

Sleep/Standby mode

How can we do better?

• Monitoring the Battery Level and Charging State• Determine the Current Charging State• Monitor Changes in Charging State• Use coarse network location
