It seems like the battery life on my iPhone 4S has gotten significantly worse since the iOS 5.1.1 update. I used to be able to standby for up to 3 days, but now the battery is draining in one. I've seen a few other reports of this, anyone else experiencing it? I may have to see if I can figure out how to downgrade to 5.1.0 to do a better comparison.

My iPhone 4 appears to have about the same battery performance on 5.1.1 as it did on 5.1.0.

Mine works just the same as before. Usually 2 days of reasonable use before I need to plug it in.

If this is any guage: I fully charged my iPhone 4S (iOS 5.1.1) before bed last night; 8 hours later it was at 98% charge left. That's with the Siri "raise to speak" option turned OFF.

Pretty darn good batter life guage, if you ask me. Many people in the past typically have complained about a huge overnight drain.

Connected to a WiFi? Push email enabled mixed with regular email periodic checks?

OP - try a reset all settings. No application will be touched. My 4S on 5.1.1 lasts 2 days easily. At 55% now and I took it off the charger yesterday in the morning (30 hours ago).
