I know we are talking about 4s with ios5, but my experence with ip4 with ios4 are turn off push and exchange mail, that two are battery hog.

This is what I got with my ip4s with ios5, no push and exchange.

Again, 5 hours usage seems to be the trend for the iPhone 4S' battery life. Even with exchange, push, and notifications on.
 
with the successful port of siri to iphone 4...is there even a reason now to stick with my 4s?

so tempted to return it :(
 
Great Battery Or Not ?:p

I agree man, I really feel bad for all the people having issues, and think surely antenna and signal strength are playing a large role. My 32gb whiphone is doing great though as you saw a few posts back 40ish standby and 5hrs usage with 20% left. I really hope the testing gets more involved and if so I'll be happy to submit some type of usage file or something or restore the phone to certain control settings, but feel good that I have everything but Bluetooth on and still getting good time.

Doubt your a heavy user , I get about 7-8 hours low use and like 5:30 - 6 hours on heavy use

What exactly are you implying with your statement? Sorry if it's obvious, but I mean we all know this is far from scientific but how is what he said at all inconsistent with your follow up of 5:30-6 hours of heavy usage. If I'm misunderstanding something I apologize, let me know.
 
drag racing zombie killer visiting the forum on safari facebook 3g on twitter email and some calls i am happy with my battery :D
 
Exchange

I've narrowed down my problem...definitely Exchange. I tried everything w/ location, Siri, etc. I was going to sleep at 100% and waking up to 30% or 40% and a hot phone. Stopped the Exchange from synching and losing only a few % at night. With location, Siri, etc. all turned back on.

Problem is...what do I do now? Is it a bad contact or something else causing a loop? Is it a software bug that needs to be fixed? I do need exchange to run on this (and it worked fine on IP4 with same settings).

I don't know very much about exchange servers at all but is there any third-party application that uses exchange you can try and see if it give you the same results? Shot in the dark
 
Hola all...

I've posted a few times in this thread and I finally returned my iPhone and got a new one.

Last night, with the faulty phone, I was at 19% with 1 hour, 35 minutes of usage. and 7 hours of standby. I tried everything, switching off siri, notifications, etc. Nothing worked.

The guy at the Genius Bar said diagnostically nothing was wrong with my battery. I still requested a new phone. No problem was his reply.

Brand new phone today and I'm at 33% with 3 hours, 30 minutes of usage and 11 hours of standby. It makes a world of difference.

I'm waiting for it to get down to 0% so I can go to a full charge and see how the performance is.

Either way, I'm happy and can make it thru a full day without having to charge in the middle of the day.

Thought I'd let you know.

:)

Awesome glad to hear it man. If your experience is anything similar to mine your experience should openly get better after a full charge/ discharge, for whatever reason. Let us know

If you look under mail then the exchange server, there's a setting for which boxes to push and inbox remains checked, even if you set the fetch new data to hourly. Damn thing demands pushing. Could be the source of many a problem.

I had Push on for my IP4 and never had an issue.

I think there are two categories of problems here. First, there are people who are getting dramatically lower battery performance than they should (50% loss overnight). Turning off all of the things that make the iPhone cool may or may not fix them, but there is probably some underlying bug causing this battery issue for these people. For me, my IP4 lasts a few days w/ the exact same settings that my 4S lasts 12 hours. Something is not right.

The second group of people are those that have all of the cool things turned on, and are getting somewhat less performance than on an IP4 or less than they expected. If you have most of the features of the iPhone turned on and your phone makes it through the day (as it should), then there is nothing wrong w/ your phone.
 
Gonna be a lot of pissed off people if they go beyond their 30 days and there's no fix. Or a fix similar to the Antenna issue on the 4, which was basically "shut up, it happens on all phones (*cough*, BS, *cough*), here's a free rubber band.
 
What do you use to view processor usage?

SYS activity monitor or System Status, both in the app store.

Wrong. Those "push" settings are simply telling the iPhone which folders to get from Exchange when you retrieve your mail. I can confirm with push turned off and fetch manually set to on I do not get "pushed" my inbox from exchange until I open the mail app.
 
Been following this thread closely...

My original iPhone (s/n starting DNPGH) was having major issues with battery life. After 2-3 hours of use and 9 hours of standby I was at 11%. Apple store swapped it out, though swore that it was nothing with my phone. I beg to differ. New phone (s/n starting C39GH) has been giving me what I consider phenomenal battery life.

As of 11:39pm, I have clocked 5 hrs 15 minutes of usage (moderate to heavy - streaming pandora while intermittently imessaging, using facebook, browsing the internet) and 17 hours of standby. I am just getting down to 50% battery.

I have iCloud off with the exception of Find my iPhone, 2 exchange push accounts, and 2 fetch accounts every 30 minutes. Push notifications are on for the apps I want, location services are on for most everything (except apps that I don't want to know where I am), though I did turn off most of the system location services. Wi-Fi is on depending on where I am, bluetooth is on when I am in the car.

Coming from a Sprint Samsung Epic, this is AWESOME.
 
Excuse my ignorance, but it strikes me that if you've got 1 email account set to push, you may as well have them all set to push?

Surely if you've got one email account constantly pinging Apple's servers checking for mail, it's not going to be a great battery drain if you've got more than one?

Or am I completely off-base?

Personally speaking my 2nd email account is used for bills and site sign ups. That means I get a lot more junk on it. So push would be annoying!
 
Mine has been going great with two exchange accounts and icloud pushing. I get 4-6 hours of usage time and basically as much standby time as I like. It will drop between 1-3% overnight.

The last time I drained it completely it was at

Usage: 6 hours, 2 minutes
Standby: 1 Day, 9 Hours

I did expect more than 6 hours of usage time though. I thought I would be able to watch movies on the thing for 10 hours straight.

Agreed. I can understand that derping around on the phone for an hour during lunch can chew through some battery. Video, internet, it's understandable that there should be a hit. Using GPS and playing music while taking a bike ride, again we're talking about some usage. Understandable. But the battery life shouldn't be so cruelly slaughtered while on standby.

The second group of people are those that have all of the cool things turned on, and are getting somewhat less performance than on an IP4 or less than they expected. If you have most of the features of the iPhone turned on and your phone makes it through the day (as it should), then there is nothing wrong w/ your phone.

Yeah. That's why I'd love it if they'd just make the damn phone thicker and put in more battery. It's an accepted fact in the automotive world that the size of the gas tank is determined by what will give a vehicle a roughly 300 mile range. Tiny gas tank for a sub-compact, bulky tank for an SUV. Doesn't matter what the fuel efficiency is, the manufacturers know that an efficient vehicle with a small tank that has a 150 mile range will "seem" worse than an inefficient vehicle with poor mileage and a fat tank.

If I'm using a conventional digital camera for an all-day event, I can carry additional batteries, even if the camera sucks them down. If I'm carrying a smartphone, now I'm trying to balance using the phone with conserving the battery so I'm not SOL before the day's over. And since we can't swap batteries, we're left with auxiliary battery kludges.

While the batteries of today are of course completely amazing to the batteries of a decade ago, the shiny new features continue to suck them dry. Just another variation on "What Intel giveth, Microsoft taketh away."

Ok. So what you're saying is even though the folder is labeled as push, that only gets taken into account if the entire account is left on as push?

I'm still trying to fine-tune how I balance out my mail. I've got my gmail autofiltered so on the desktop everything is peachy. Important stuff at the top, notices and the like in folders. Can review and delete as needed and all my important mail gets my attention immediately.

My work account has a mix of important stuff and dross. My spare personal account is for other stuff I was trying to segregate by account to see if it might improve my mail prioritization.

Right now when I hear the mail ding it's hard to say which account is doing the dinging. I know I was hearing it more frequently than once an hour and the change to advanced mail features manually setting the accounts to fetch might have improved.

If I set the main push to fetch option under mail, is that change inherited by all accounts? I would have thought so but I was constantly hearing dings from my phone like it was getting the messages fairly close to realtime, not the once an hour ding I'd usually expect.
 
In Settings > Locationservices I saw OkCupid using live/background location data, I've disabled that for now. Lets see if my iPhone now sleeps for more than 50% of the time during standby.
 
Definitely subpar compared to the iPhone 4 but its not disastrous.

-Wi-Fi On...mostly (ask to join off)
-BT Off
-Notifications On (excl some games)
-Location Services On (excl iAds, Time Zone & Diagnostics)
-40% Brightness
-Light music, surfing, maps, gaming and calls
-Heavy messaging
-Exchange Contacts and Calendar
-Fetch 2 Mail accounts hourly
-Siri on (raise to speak off)
-iCloud on (excl Contacts, Calendar and Photostream)

Did you have your iPhone 4 with iOS 5 to actually compare?
