What does this icon mean?
My iPhone 4 battery is draining 1% on every 3 minutes. I fully charged iPhone and removed all the apps from multi-tasking expect the Apple pre-built apps. Even I turned off all the location services, notifications. Reduced the brightness and turn off several additional settings in apps including turn off EQ and Sound Check options in iPod.
Currently I've 3 mail accounts configured for Fetch and 1 Exchange Server account configured for Push.
Current Battery Status: 90%
Time since last full charge:
Usage - 44 minutes
Standby: 4 hours, 9 minutes
Any further suggestions would be greatly appreciated! Thank you.
Sony, Windows 7
