Wait you said it had already been off the charger and used a bit while still on 100% so that 15% drop was not just during that short45 min time. The battery percent meter does not change by the second (actually i dont think its real accurate to start with) Anyway in reality you used 1 hr +23 min +45 min since the 100% mark. Of course you would have to run the math to determine if you are at or near spec based on the type of usage that 23 and 45 min were and divide out the standby. So at a glance 85% remaining may not be too bad afterall.
I assume you have the specs to use so 8hr for talk, 6 for 3g internet and 9 wifi (7.5 is a good number to use for average. In case you are not aware or dont want to figure it out stdbytotal/200 for stdby , talk time/8, internet time/7.5. add all those together =x then 100-x to see what should be remaining usage reported. That is a very close estimate to see if you are at or near Apples posted specs.

This is where your particular situation has you blinded to additional realities...... My situation leads me to a different conclusion. I shut off only the Time Zone and iADs location services. I have 3 email accounts set up, with two being PUSH and one of those Exchange. I use wifi all the time and BT is on for when I'm in the car. I have icloud running, iTunes Match running, photostream running. I don't waste time clearing out my app history every time I'm done with an app, so my previous apps bar has some 20 apps listed in there.
I charge my phone every night, while sleeping. 64gb 4s received on day one of the release.
So, I upgeraded to 5.1 yesterday evening, then plugged in at bed time. This morning I unplugged and all the while attached to wifi, I lost nothing ---- After 2+ hours, my phone was still at 100% with 23min of usage.
Time to go out --- I left home, stopped for something to eat and while there (on 3G or AT&T's faux 4G), worked a bunch of emails, did a little facebooking and read some news stories. Immediately, when leaving my wifi connection, the battery began to drop quickly. After some 40min on 3G, with steady usage, I was donw to 85% remaining. So that's 15% in less than 3/4 hour. The phone was warm, but not hot.
This reinforces my belief that the problem is in how the 4s and iOS 5 manage cellular data with the new dual antenna system. For the heck of it, I brought my iPAD-1 with me, set up with the same exact email configuration, same wifi/3g connections, same iCloud, photostream and iTunes Match settings.... After all morning and part of the afternoon, it's at 98% remaining after 8 hours. I know I'm comparing Apples & Oranges (so to speak), but to see the phone battery drop so quickly, just by leaving the wifi environment, to me, is very telling.
I'm guessing that APPLE is not going to be able to fix the 3G battery drain issue and iPhone 5 is our only hope. And that will require a bigger battery, and probably a bigger form, which isn't necessarily a bad thing.......

Complaining about battery use because things are on isn't beneficial. Complaining about excessive battery use with NOTHING is on, is why people come here.
Bottom line: There ain't no such thing as a FREE LUNCH.
