    My iPhone 4s battery life is terrible. I'm always experiencing a 10-15% drop per hour. I unplugged my phone this morning at 8:20 and it's now 12:15 and my battery is on 53%. I have almost everything turned off that you possibly can. My battery drains dramatically when my phones on standby. Also, my phone overheated for the first time today. I hope I won't have to get a new phone but might have to.

    I set my diagnositics and usage to "don't send" initially and still have the battery issues.  Though they do seem to be better turning my wifi to off.

     

    Seems like the wifi is always trying to cconnect to places its always connected to and may be using a lot of power.  I'll keep playing as well.

    Battery life seems to be a widespread problem with the new phone. I would suggest going to: settings/about/diagnostics & usage/ and clicking 'don't send'. Mine was set to automatically send (factory setting?) When I looked at the send data there were 30 sends on 10/14 (I didn't even get the phone working until 4:00 pm), 150 sends on 10/15 and 328 on 10/16 and I'm not going to even begin to count today's. So essentially, every 4.4 minutes I'm sending diagnostic data to Apple at the expense of my battery life. 

     

    I turned this off. We'll see if this makes a difference.

    I am having the same issues with Battery life too.

    Having spent a considerable time with my 3GS, i could see 4S is consuming too much power.

    Without having to do anything, it just drains 100% power in less than 5-6hrs. And i did find it becoming better the second day. Will have to wait to see how it improves.

     

    There is no point in having an iphone and not using the location based services, reminders and Siri.

    If everything needs to be disabled to save battery, then why should i spend hundreds of $ to get a 4S.

    I hope apple is listening, will take this seriously and fix the issues.

    Any chance you have a location based reminder setup?  See:

    An update to my last post: after a full 0-100% charge last night, I woke to find the 4S on 98%... so drama there. However, after only just under 3hrs Wi-Fi use all day, plus a couple of calls, I'm down to 50%. The tech specs state 9hrs Wi-Fi use. Something's definitely not right.

     

    Just noticed some people on here talking about the diagnostics... mine was on too, and had a hefty number of entries. That's off now and I will do some more checking over the next day or so. Generally feels like I'm getting less bang out of this battery in comparison to the iPhone 4. Certainly doesn't feel improved.

    This is not just a 4S problem. I have a 4 and have been dealing with it as well although I don't think it is as severe as on the 4S. I turned off the time zone thing and it seems to have helped. Today will tell for sure but so far things are going well.

    hi

    reminders and calendar have a setting to sync the last 2 weeks events....up to ... all events in settings>mail, calendar...at the bottom of the submenu screen

    everytime you access or keep running the reminders or calendar they sync trough cellular network

    and syncing...and syncing...and....

    and eating up celular data usage (0,3-0,5 Mbeach time they syc) and eating up batery life

    if there would be a option to sync it just when icloud is updating (for the period allready setup as explained before) it would spare our batery life and celular data usage

    but then carriers partners would charge less and theyr interest is to charge more...on our expence and iphone batery life

    I did a restore, just put my apps/music photos.  So far no mail, calendar, etc.  Battery is running great, 100% charge after 80 minutes (granted phone isn't really doing anything).  Now I have to turn things on one by one and add all the accounts.

    I'm having similar issues.  I had a 100% charge at 5:45 am, and with no usage was down to 62% by 9 am.  This is my second 4s phone.  I reported the problem to Apple on Saturday afternoon, and the Genius checked my battery, showed perfect life, and reset my phone.  After still having problems on Saturday night/ Sunday day, I took my phone back into Apple, and they replaced it for me. 

     

    My second 4s is doing no better than my first one did.  To confirm, my WiFi is off, everything that can be pushed is off, and my diagnostics were always set to "Don't Send".  I'm still loosing 20% batter per hour with no usage. 

     

    Going back to Apple tonight to complain and see what they can do.

     

    Also, my bf got the same phone and has no issues with the battery life.  Apparently not all 4s are having this trouble.  But he's on AT&T and I'm on Verizon.  Could that have something to do with it?

    @Jon... So basically you have an iPod at this point. Well, not even that if you haven't added mail and calendars yet. At this point you have a storage device that you can listen to music or look at pictures on, and nothing more. So there shouldn't be any battery drain after 80 minutes if you're not even doing that. Once you add anything to the device that requires it to connect to wifi or a cellular signal the problems will start and the drainage begins.

     

    I'm seeing very poor battery performance on my 4S. I'm now at 75% after unplugging from a full charge this morning less than 5 hours ago. At this rate I've got a dead iPhone in 20 hours when it's doing nothing. The keynote from Apple states that you get 40 hours of music on a full battery. Well that obviously can't be accurate at the current drain rate when the phone is doing nothing (at least nothing that I'm prompting it to do).

     

    I believe that iCloud and iOS5 may be the culprits. I have an iPad 64gb wifi only that I unplugged from the charger at the same time as my 4S this morning. Since it's not a phone and I haven't been streaming any videos it shouldn't consume as much power. So far today I've sent a couple of emails and did some safari surfing which maybe had me use the device 1-1/2 hours in all today. My current battery charge is now at 63%. Prior to updating to iOS5 and adding iCloud it would typically be in the low 90's to high 80's a this time.

     

    It would be interesting if someone who had the resources could do side-by-side tests of identical devices doing identical tasks - one using iOS 4.3 without iCloud and the other using the latest iOS5 and iCloud. I think the results would be very obvious and you would find better than a 20% increase in battery consumption, across all devices - iPads, iPhones and iPad Touches. Apple, Engadget, Gizmodo, MacRumors: are you listening?

     

    C'mon Apple - I think it's time to come clean and let your users know that you're aware of the inherent battery issues with the new software/firmware. We're loyal users and we'll understand. We've lived through the 6 hour activation delays on the 4S and the Siri server issues. We're a patient bunch, we Apple users. We just want a statement that you're aware of the problem and you're working on a fix. Do the right thing and let's not have another "antenna gate". Just let us know when we can expect to have our devices working as effiently as they did before. Thanks!

    I am an other disappointed customer of iphone 4s. Battery life is not good at the moment draining quickly, can't get a full day use with very light use at this point. Phone gets warm and seems locked in a loop or something. no apps running. not sure if this is ios5 related or battery related.

    I posted earlier and I had the same issues.  I went from 100% at 7am to 18% at 6pm with very little use. 

     

    Since then I made a lot of changes to the phone.

     

    I turned off reporting to Apple/Diagnostics, I turned off everything in iCloud and reset and readded the items.  I turned off unused calendars and email items.  I don't use Fetch, but I turned that off as well.  I turned off Pinging.  I removed items from the new Notifications Board that I am not wanting to use anyway.  I used battery magic to do a full recondition charge of the battery.

     

    I started using the phone at 7am today for various stuff, and it is now 1pm 6-hours later and I went from 100% this morning and now am at 96%. 

     

    I don't think it is a hardware or iOS direct issue, but a configuration issue.

    Update after 2 hours, 15 minutes.

     

    After the first hour my phone was at 100%, no mail/calendars/notifications (other than text messages).

     

    I did  receive 3 text messages during that time.

     

    I then configured Apple Mail and First Class mail and setup notifications for the latter (and I get probably 15-30 messages/hour during work).  I'm at 94% right now.  Next step is to setup all my calendars and address book shares to connect to our SLS 10.6x iCal and Address Book servers.
