For people using iPhone 4S with unreasonable battery drop.

Did you restore from your previous iPhone or started as new?

My 4S showed 15% decrease on standby over 6 hours when I restored my iPhone 4 backup to it. However, the battery life behaves much better when I did a full erase and started it as new (Standby 1 day, 2 hours with 5 hours of usage @ 40%).

Since I use iCloud for contacts and calenders, the only thing that I had to do for the "starting up as new" was to adjust my setting and add back my app.

Here are some of my stuff I turn on 24/7. Wifi, Bluetooth, 3G, Location Service and basically everything that people are saying its draining the battery.

I also did a battery calibration by draining the battery and recharging it to full. If nothing works, then wait for Apple to release a software update. Their engineers have been working with a few selected people that experience the battery life problem.
