    Been using the 4S for 2 weeks now -   I have noticed that I am losing 1% of power every 5 mins with:


    - brightness turned to minimum (i am reading in bed)

    - No network connectivity (WiFi off, BT off, 3G off)

    - All data streams set to Fetch, not PUSH

    - All apps capable of Push, such as Facebook, set push to OFF


    No apps running.  checked with System Activity Monitor (Free from App Store) -  checked all services running - there is nothing "rogue" running in terms of services, no idle processes, CPU is mostly idle or less than 5%, and yet i am draining, draining.


    Wondering if it could be the power consumption of the new antenna?  I am the radio is always on unless you go to airplane mode.   In any case, your guess is as good as anyone's.

    Why can't you hold off for a week or two untill this is fixed.  The ods are VERRY small the problem is the battery.

    Coming from an iPhone 4 - the iPhone 4S is a nightmare. To make matters worse I have been without power since Satureday morning so charging every 4 hours isn't an easy task.


    I unplugged this morning at 5:00am. By 7:30am I was at 85%. All I did was reply to 3 emails and 3 texts. Nothing else. With the iPhone 4 I would be at 99%...maybe 98%.


    Apple - please help. I am begging...

    Interesting. How do you know?

  • cwaxe Level 1 (0 points)

    Same with my iPhone 4S i will send it back and use my iPhone 4 again.

    Siri i will miss you but that's not acceptable at all.

    iPhone 4S, 16GB Black, Verizon. 


    my battery life has not been great, but i use the phone quite a lot during the day so i just chalked it up to heavy use (although no other iphone i have ever owned has ever had such poor battery life). 


    but last night, i went to sleep with a fully charged phone (battery charge was at 100% as it had been on the charger just before going to sleep).  i woke up this morning and my phone was very hot and at 42% after just sitting all night long not being used at all.


    something is very not right.  just wanted to add my experience to the list here.

    Categorically, for me, the answer has been to turn off Automatic sending of Diagnostics and Usage data.


    Settings > General > About > Diagnostics &Usage > Don't Send


    This fixed the battery drain on both an iPhone  4 upgraded to iOS 5 synced to a Mobile Me account, and an iPhone 4S with an iCloud account. Both phones have many awdd entries in the diagnostics and usage data.

    After much research I have done just 3 things to my phone and my battery now lasts 100% longer than it did:


    1) Did a full restore from iTunes

    2) Disabled Auto Time Zone (Settings -> Location Services -> System Services -> Time Zone) and any others I didn't require.

    3) Turned off calendar from the Notification Center (Settings -> Notifications -> Calendar).


    Exchange Push, iCloud, Siri, and all the other things that make the 4S great are still enabled and my battery is lasting as long as I would expect for a change.


    Best of luck to you all.

    I tried everything suggested up to the point of resettng from new.  Ive had improvements on the iphone 4s.  Can posters here post their battery data like below so we can compare each orhers iphone 4s batts and everyone will know how others are doing.


    9am - 12midnight (black screen fully dead batt) - 15 hours total = Average of 7%/hour.


    This is from a normal day, txting, calls, surfing, using apps, etc.

  • chnacat Level 1 (0 points)

    i already had that turned off, never had it enabled....

  • iregan Level 1 (0 points)

    Well 85% compared to 98% might seem bad, but keep in mind, the 4S has a much faster power hungry chip. Plus iOS5 and the cloud probably contribute to the drainage. Supposedly the battery is only slightly more powerful maybe not enough to compensate for the new power demands tho.


    I am sure Apple is working on a software fix to improve the integration somewhat. But i would expect some difference between the 4 and the 4S due to the above factors. As long as it makes it thru a day of use, i wouldnt get too upset. This isnt a basic flip's the smartest phone around. Basically a laptop in your pocket.


    Think about that. If you use a laptop or ipad extensively throughout the day surfing the web, answering emails, playing games, skyping....or any other activities....chances are you will be charging it up over night for the next days use. And those devices have MUCH bigger more powerful batteries than the little iphone.


    Not trying to dismiss valid complaints....just saying, you gotta keep this in perspective. From what i hear android smart phones suffer massive battery drain as well. Part of the trade off i think to have a laptop in your pocket.


    Still....i am sure Apple is addressing the issue and will improve it as best they can.

    I've only had the 4S since Thursday (4 days) but in that time I've already become familiar with the abysmal battery life. Examples:


    1 - I need to charge my phone every day at work or else I won't make it through the day.

    2 - Even at weekends, where I'm mainly on wifi, I get to the end of the day on less than 20% battery. My 4 managed this with 60-70% charge

    3 - This morning, I unplugged my phone from the mac-mini I use to charge it overnight and checked it 10 mins later. My charge showed 93% with the Time since last charge / standby both showing 10 mins.


    Since I got my phone I've tried a restore and I've tried a complete discharge / recharge but this has had little / no effect. I give it till the end of the week and, provided my 4 hasn't sold by then, I'm seriously considering taking it back.

    My girlfriend just bought an iPhone 4S but her iPhone is still in "SOS" mode because her number hasn't been ported yet. It's constantly been connected to Wifi since we bought it and the battery has been perfect. Nothing to complain about.... Yet. I wonder if the cellular connection has something to do with the issue? I bet most people haven't had the phone not connected to a carrier network.

  • QueeeeenY Level 1 (0 points)

    After I read a lot of info on the battery issue and because I was really unhappy with the battery life of my 4S, I tried all the recommended steps.


    1) I turned off notifications completely, none of them are in the notification center.


    2) I turned most of the location services off. The only one I left on are Cell Network Search in Location Services -> System Services. I only left that on because I had some severe trouble getting my o2 Germany sim card to work.


    3) Brightness of the screen is under 50%


    4) iCloud is off (again, due to problems with my O2 sim card, I was adviced by O2 to turn it off, but it might play a role in the battery life too)


    But I have my mail on push and I check my phone a lot. Last night, I closed all running apps, but I had Twitter push and email push on and I received a bunch of tweets and mails and only lost 20% of battery. That seems very normal to me.


    I have to add, my phone is still new, I only charged it fully once. So the battery hasn't reached its peak of performance yet.


    I hope my suggestions help you guys!

    In my Wifi-Router logs I see that my iPhone 4s connects and disconnects every second.

    Our iPhone4 and iPad doesn´t do this.

    All those workarounds changed anything for me.

    My Battery ist draining fast
