Still as "bad" as it ever has been for me after updating to 6.1.
Yesterday I was plugged in most of the day so didn't really pay attention.
Today, fully charged before leaving home for work.
Got here about 10:30am, it's now 1:20pm.
iPhone 5
remaining: 66%
Time since last full charge
Usage: 1 hours, 46 minutes
Standby: 3 Hours, 11 minutes
I've got most location system services switched off, only have Compass calibration, time zone setting, and traffic, switched on.
Have used facebook and iMessages, that's about it. Facebook location is switched off.
