iPhone 4S
BatteryDetective: -95mA, -108mA, -134mA, -89mA, -106mA

All phones have the same brightness, connected to the same wifi network with same carrier. Settings like Bluetooth and Location services are OFF.

What exactly are the tasks being performed at these random intervals? Or is the phone simply on standby?

All phones are running with no apps on multitasking bar, doing nothing. They are the idle battery consumptions.

And were both brand new phones with no previous battery cycling?

And then you also have to wonder what other code is running in the background on the 4s, that isn't with the 4? Transparent code to the user, that is.

Not sure about the op, but i was talking the same thing with a friend. He bought a new iphone 4s for him and a 4 for her wife since she dont care. He did a test with the factory realeased ios 5 and same aps no apps running and the ios was consuming a bit more. He was telling me around 15-20% more per tick up to 30
% after while.

So more hardware uses more battery? Very interesting.

Did you turn all of the systems location services off like iAds and location based diagnostics?

I think it's mainly because the 4s has that feature built in to help local and government official locate you in an emergency or if you are wanted by the police or FBI.

The iPhone 4S uses 50% more battery life in standby than the iPhone 4 ( according to Apple themselves ). So when you're doing nothing ( idle ), the drain on battery is a lot higher than the iPhone 4 regardless of what settings is used.
