Honestly, what are your expectations in this usage scenario? Out of 1.5 hours you made a 45 minute phone call and surfed the internet posting on the forum. I'll assume you call on 3G and used WiFi for the surfing.
The stated battery life of the 4S in that scenario is up to 8 hours, maybe stretching to 8.5 if I am being generous.
If you used 3G to surf too, the stated battery life is up to 6 hours, which we can stretch to 7 for the phone call time.
You are getting, by your own admission, about 7.5 hours battery life based on completely non-scientific observation. And you are calling that ridiculous?
I don't deny that there is a battery problem on the 4S and I am sure Apple will rectify it, but I think you guys need to put it in perspective to avoid future disappointment. I've been running b2 since it came out, and so far managed 2 full days on standby with about 3 hours total use twice in a row (currently on my 3rd cycle and looks set to be around the same again), which is my normal usage pattern for my phone. It's worse than my iP4, but I expect it to be given the upgrades in hardware and IOS supported by negligible change to the battery capacity.
That's my 2c.
