I bought my 64gb 4s Friday night. I took it home and restored from a backup. I charged it to 100% and unplugged it before I went to bed that night at 2am. My results are below as soon as i reached 1% about 30 mins ago. I've browsed the web mostly on WiFi and have made a few calls along with testing out Siri several times (20 times?). I think these results are good even without having conditioned my battery, so I can only assume they will improve. I'm happy. :)

That is how I would expect an iPhone to perform! If I cannot get mine back to that standard it will be swap time.

I'm having a hard time killing mine. Unplugged this morning at 11:30. Went to work for eight hours. I work in the dead zone in my building. Left work, and it was still at 76%. Came home and messed with apps and websites trying to kill it. Finally gave up and plugged it in at 30% at 12:30am.
 
I found this thread on Apple Discussion:

https://discussions.apple.com/thread/3378076?start=0&tstart=30

Look for HDCrazy's suggestion at the bottom of page 1. This seems to have fixed quite a few people's excessive battery drain.

Also, another thing that helped was to not automatically send Diagnostics and Usage data to Apple - settings -> about -> Diagnostics & Usage

Nothing seems to be showing up for that link. Are you able to post what he recommended?!
 
Delete your MobileMe account
Delete your iCloud account (save data on the phone)
Do a hard reset
Set up iCloud and MM again.

Or, just c/p

I think I got it!!!
It seems to be a conflict with mobile me and icloud.

What I did;
In e-mail settings delete the original mobile me account.
Then I deactivated everything in icloud settings (when prompted if I should keep my info on my phone I opted to keep my information on my phone).
I then did a hard reboot.
When the phone powered back on I then went back into icloud and set it all up again.
This was about 45 min ago and I have only lost 1% and it’s probably from using it.
Good luck and please post your results.
 
This is bad...

My battery is being AWFUL.

Yesterday I charged mine at 12 noon, only to have it finish by 10.

Usage: 5 hours 36 minutes
Standby: 9 hours 59 minutes.

That's down to 1% from 100%. Not a single game played. Just music and light web.

I then charged it up fully up to 100%, unplugged and went to sleep at 0100 Woke up at 0730 to 72% battery!!

I'm really considering this to be a dud battery...
 
I say let's all complain to Apple. Hopefully then we'll see a fix soon, or at least if it's a hardware problem let us exchange it for one that actually works..
 
I have an exchange account and I am having terrible battery drain. I have just deleted it to see what happens. What I don't understand is I have charged my battery overnight and just unplugged it - it is now showing 1 hour standby and 40 minutes usage even though I haven't used it all (or started any apps).
 
Last night decided to test this... so after 7 hours 22 mins of stand by, and 17 mins of usage while I slept the phone lost 4% battery life. Seems reasonable?

I was just about to post the same thing... My usage is showing as 1 hour 11 minutes since last full charge, when in fact actual usage is around 10-15 minutes! Clearly the phone is doing something in the background that is draining the battery. Unfortunately I had this issue on iOS 4, and it comes and goes.
 
I have most push off

mail checks once an hour and i think thats it..and i have lost 20% since about 9pm with a lot of texting and light phone use....I don't think this is good..lets see how the rest of the night goes,but if it keeps up then idk i think ill have to go into apple on monday and get a new phone. the battery just goes away..and if i even decide to use location reminder then I'm ****ed. Whats the point of having a feature you can't use.

You can use it for marketing and sell ****tons of units.
 
It looks like its not just a 4s issue with the added Siri feature, but maybe more of an iOS 5 issue. I did notice my iPhone 4 with ios 5 loaded drained a bit faster.

Any iPhone 3GS, and 4 users with battery issues using ios 5?

There is a thread started on this over at Apple. It's gaining momentum:

https://discussions.apple.com/message/16345085#16345085

3GS user reporting in, noticing a small to moderate decrease in battery life. Still nowhere near the levels I got from iOS 3.x.
 
So follow up to last night...

12:06AM - 82%
I didn't touch the phone, but to take a screenshot to record this...
12:55AM - 68%
Went to sleep, phone not plugged in.
06:41AM - 58%
Woke up and took another screenshot...

This time when I got up however, the phone was cold to the touch. Last night after I removed it from the charger it was still very warm 2+ hours after I unplugged it and it was just sitting on my desk and it's not even in a case yet.

I say we ALL call Apple, and let them know what's going on... no need to be rude about it, although it's mighty frustrating!

However if people don't report this it may not be quickly addressed.
 
The 4S is my first iPhone so I don't have a comparison but the battery life really doesn't seem very good. I'm not too demanding on it and it will lose some 30% by late morning to midday. I'm not looking forward to the days when I need to use it a lot, having to worry about killing the battery. :rolleyes: You should be able to have a full day without getting anxious about battery.
 
Go to settings - Genaral - Siri - Raise to speak - OFF

And also Settings - about - Diagnostics & usage - Dont send

This has increased my battery life alot!
 
Wasn't there an article a while back about turning Ping off under "Restrictions" in order to have a better battery life?

I did that when I got my 4S because I remembered that from a while back, and I don't use Ping so no big loss, and my battery has been performing considerably better than my 3GS. It has yet to get down to 50% before I plug it in for the night.
 
Is my battery life bad?

My standby time is great... 100% to 98% in 9 hours...

However when I USE the phone it drains fast.

I used it for MAYBE 15-20 minutes, read a few articles, sent one voice text... BAM 92%.

It drains in front of my eyes while I use it.
 
I have 42 minutes usage and 3 hours 24 minutes standby since last full charge, and I'm at 85%.

I see a slight improvement from my iPhone 4.

I haven't fully run down the batter yet on the 4S because I do plug the phone in every night... I guess I should let it run all the way down?
 
Just a update from my original post. (https://forums.macrumors.com/posts/13636400/)

My battery was at 22% at midnight, after pretty normal usage. I consider this to be a normal full day.

This morning, my phone is still at 100% after being off the charger for an hour...not bad at all.

I think the battery controller just wasn't fully charging it that first day.

Hope you guys figure out a way to get around it like I did. (mine is pretty anecdotal)

I have this as well yet still lose about 2% an hour in standby which is roughly four times faster draining than the advertised 200 hours of standby.

There was a post from a user on the Apple discussion forums claiming MobileMe is the culprit. I'm a MobileMe user myself (can't move to iCloud yet); how are the other MobileMe users here fairing w/ their 4S battery life? Better or worse than iPhone 4?
 
Hold on...
Who goes to bed without plugging in their iPhone?

Thats what i'm saying! Who wouldnt plug their phone in when they go to bed? Thats common sense.

why cant you move to iCloud yet? I moved to iCloud last wednesday.

On the OS X side of things iCloud requires Lion 10.7.2. I have two machines running Snow Leopard that can't be updated to Lion just yet -- one of them is a work machine and the other is a machine w/ apps not supported by Lion. Hopefully there will be a patch for SL to add iCloud support but I'm really in no rush... unless of course this 4S battery dilemma is the result of MobileMe.
