iPhone 4s Battery Life?

My iPhone 4s battery seems terrible! Almost equivalent to my 3GS and it's terrible battery life. When I got my iPhone yesterday and restored from backup I noticed nothing really changed with minimal usage and standby! Is this normal or should I consider setting it up as a new phone because maybe something is running in the background that's causing it to drop a percentage every few minutes under light usage? Input would be great!

I found a lot of issues in settings, things turned on, fetch turned on, too much in location services, turned PING off in settings, and more. Also people have been saying there is an iCloud / MobileMe issue and to turn off each item individual, reset the phone, then turn them back on one by one. Also seems in some of the emails sync of calendar and notes are turned on, so I turned them off as well.


Doing a full charge / top off with Battery Magic and will test again tomorrow.

I just found another thing that might be draining the battery... Diagnostics & Usage...

It was set to Automatically Send(don;t remember if I agreed to that or it is the default) but the shocking part is if you look in the 'Diagnostic & Usage Data' you will find many, many sends per day...on mine, about 30 per day...

I changed it to 'Don't Send' and will see if that helps...

I'm worried about my battery life as well... It was a huge investment for me to upgrade from the 3GS to the 4S and for example, I fully charged the battery overnight, woke up and took the phone off the charger to go to work at about 8:45 a.m. it's 10:40 a.m now, I have not used the phone at all and it's gone from 100% to 87% without using it... My 3GS battery life was even better than this.


I read somewhere that the battery "comes to life" after a few drains and recharges. I sure hope that's right...
