All you guys who are saying you have no issue with the 4S's battery life must be coming from the 3GS or not have had the iPhone 4, huh? Guess you can't miss what you never knew...
 
I have most services turned on, two exchange accounts (one fetches hourly, the other on push), iCloud, and all location services except for time zone.

I had a little bit of weirdness on day 2 (dropped from 100 to 95 in the first minute of being off the charger). I adjusted one of my email accounts to fetch, turned off location services for time-zone calibration, and did a hard reset. The let used the phone for two days without charging, until it turned off.

Charged it back up and pulled it off the charger this morning at 7am. 1 phone call, a few texts, some maps usage, some light web browsing and I've got 84% remaining at 7:35pm. To me, this is more than acceptable having come from a battery-sucking EVO...

I have had both, and my 4s battery life is excellent, I have to try really hard to kill the battery, after a long day of emails, web browsing, and texting I still have somewhere in the 40's percent
 
I had battery issues and resolved them. Deleted and recreated my Exchange account, and also noticed it was stuck on a WiFi sync (greyed out) waiting for my computer to come back online (It was online, but that's a whole different story). After clearing that and setting my Exchange mail up again from scratch, I'm back to about the same usage I was getting from the battery on my old iPhone 4

How did you clear the WiFi sync issue where it was greyed out? Mine is greyed out and says "Sync will resume when "USERNAME" is available.
 
well i was on the phone for hour and half and i got 69% left as of right now but i'm sure i can manage to get a whole day and charge it by bed time tonight so that's good enough for me.
 
No problem with mine, 15 hours+ stand by, 6-7 hours usage. Thats surfing the web, tethering my iPad, emails, streaming music, texting, phoning, emailing. Location services are on for the apps that I want to use it (not all), siri is one, blue tooth is on
 
Today, I took the 4S off the charger at 100% at 7:15am. It died at 8pm when I left work. I got 5h36m of usage, 25-30min of which was music listening on the iPod with headphones. I sent and received some emails, browsed some light websites (nothing heavy...mostly macrumors, ny times mobile website), texted a good bit, maybe 5 min of voice calls. Definitely not as robust as my iP4 on iOS 5. I could make it through a day from 6am to 10-11pm when I was on call at the hospital.

Wifi was off, location services on, but disabled for system services except cell service and traffic, and all my notifications were on.

I'm thinking of using my ip4 again and keeping the ip4s in a drawer and come back to it when battery life has been figured out. I haven't had to be so conscious of my battery since my 3GS.

I changed from an iPhone 4 to a 4s. No other changes in usage or apps. I get less than half the battery life now than I did.

Not sure what other facts need to be analyzed to know there is a dramatic loss in performance.

This is a no brainer! Don't need to do this, do that, turn off this, turn off that, dance in a circle three times. Blah blah blah.

Same apps, same place of work, same carrier, same music, same ,same.

Half the life. Doh!

Facts need to be analyzed because not everyone is having battery problems. That's why people are trying to figure out what might be causing it. It's pretty obvious that it's not an issue for everyone, so we need to look at what the differences are in people's phone setups, etc. and see what the problem might be.

Some people think it might be an issue with the new antenna. Could be that it's causing people's phones to constantly switching between antennas and searching for the best signal. I'd say that's a possibility, since turning things on/off only seems to help a small portion of the people having problems. It may have to do with the location you're in and what the phone is doing to get a signal. It's just a guess, but it's as good as any others I've heard.
 
No issue with my battery at all, I'm happy, and my wifi, and location is always on -

Some guys actually seem like they have an issue, (software prob?), and other's just seem to be whining for no reason - :rolleyes:
 
I leave WiFi on but turn off the "Ask to joint networks" part so it just connects when I'm home and if I want to join a wireless network while I'm out I can do so easily but it's not always searching.

yea i usually turn wifi off but will do this now. i get about 5-10% worse battery life than the iPhone 4. i mean that i used to end the day with 15%-25% and now end with 5%-15%. i know with notifications and iCloud and different hardware it won't be as good. it was much worse but I'm on about the fifth charge down and up so that should do it. I'm not too unhappy. Ill rearrange some settings to get it as close as possible as i used to with my 4.
 
Same here.. Go to sleep with 90 %.. Siri, bluetooth gps off.
in the morning - phone dead, alarm didnt even go off.

This couldn't be any further from the truth in my case. I'm on my second 4S already and both have exhibited the same problems. All extras are turned off. No Siri, no location services, no iCloud. Just the phone and wifi. Both phones reached 10 percent or less after less than 7 hours off a full charge.
 
Those of you getting great battery life. As in 6+ hours of usage. Are you using iCloud and most of it's features?

I use iCloud set to manual and not push.
 
I don't have any problems with battery at all. I do not have or used iCloud yet.

Today charged it till 89% and had to stop charging @3:15pm because had to go, now returned home and it is at 84% @10:30pm. During this time I've sent several text messages, my two emails are pushing, and I received several email and answered them. Location services and blue tooth is off. So about 7 hours standby with some usage and only 5% dropped! I think this is really good battery life :):):)
 
I've noticed that a lot of the images with high battery life returns show a wifi symbol.

I think whether or not you are mostly on 3G or wifi probably makes a significant difference...
 
I'm using iCloud. I have two exchange accounts setup to push email. Gmail and work, so I'm getting a lot of emails from work. I have wifi, bt, and just about all location services on except for time zone.

So far, 3 hrs and 40 min ago since my last full charge and it's down to 88%. And that's with using it for fb, instagram, texting, etc too.

No complaints here.
