    Your battery seems fine, but as prluk said, turning all those features off defeats the purpose of getting this great phone.


    I have everything turned on (except for Bluetooth and a few location services) and I get about 5-6 hours of talk time /browsing/gaming with 1 day standby - obviously that's with very heavy usuage. Battery life isn't great but I can live with it since it usually can last me a day without charging, and I always charge the battery every night before going to bed.


    So don't be too paranoid about the battery life, just use the phone for what it is and take advantage of everything it has to offer, you'll be amazed at what it can do and eventually the battery issue becomes secondary.

    Was this officially from Apple or you heard it somewhere else?

    Also go to location service and click on system services and would be wise to turn off diagnostic & usage, location based iads, setting time zone and traffic.

    Who knows - why 3G most times turn on by itself ? ****,,,

  • Neurone001 Level 1 (0 points)

    Under iOS 5.1, my battery wasting problem is fixed by doing a "reset all settings".

    Before the reset, my standby/usage time ratio is 1:1.

    After the reset, I reintroduce my preferred settings (wallpaper ringtones etc) and the standby/usage time ratio stays excellent for exemple 10:1 to 50:1 depending of the usage. On asleep mode, the battery discharge at a rate of about 1%/hr, which is fair.

    All others things are equal, I use liberally bluetooth, 3G, e-mail, push notifications, localization services, apps in the background, a good screen brightness etc...

    The battery life is clearly improved by the reset. The only conclusion is that most likely there is a mysterious process running in the background and wasting battery life. This process is eliminated by a reset. Unfortunately, the process reappears as soon as you charge the battery again...

    It is very annoying to do a reset and reintroduce all your settings after each battery charge...

    Apple people should do something to fix this bug.

    Hi to everybody.

    I was doing something like a testing and getting experiance from all the stuff that may cause drain of Iphone 4S's battery. What I figured out is that you can use your old back up, but always do a RESET after it . Then just re-enter your mail accounts go inside them and let them load all the messages then close your mail accounts and open them again and see if it is still loading or it says updated. But the most drain in my Iphone was when it runs SKYPE in background ! DON't leave apps in the background ! I have push, locations everything turned on as it should be if you want to use your iPhone like an iPhone. So I got 5 hours, 11 minutes USAGE and 1 day, 21 hours STANDBY still having 20% battery. I think this is pretty good. If you have any questions feel free to ask

    RE: shutting down apps.

    First, it is true that not all the apps listed in 'recent apps' when you look at the multi-tasking bar are actually running, but Apple doesn't distinguish between an app that has been shut down, and one that is still consuming resources.  This is something I would REALLY like to see in IOS 6.  Apple claims that most apps shut down after, at most, 10 minutes after you click the home button for that app.  Unfortunately, there is no way for the user to easily distinguish the apps that are still running from those that just remain in the list, but are not running.  Worse, apps don't usually warn the user that the app will continue to do its thing, consuming battery power until you specifically terminate it from the multi-tasking toolbar. 

    Also, I found that when an app doesn't terminate properly, the only way you know it is still trying to end is that you suddenly get excessive battery drain.  Usually, turning the phone off and back on fixes that, but I have had to reset the phone a couple of times to get rid of crashed apps that are still using cpu time.  Apple really needs to work on this for the next release.

    I have turned off ALL the functions in that area.  I am sure some of them have little effect on battery life, but I don't need Apple looking over my shoulder all the time, and using 3G data if I am not at home.  Which reminds me, I need to check my wife's 3GS to see that she isn't using 3G data.

  • NorbbertM. Level 1 (0 points)


    Everything on, except 3G and push-services.

    After installing 5.1, I did a reset of the settings.

    I thought I'd share my experience and solution to my dramatic iPhone 4 battery usage.


    I've had my 4 since launch day and had absolutely no problems with the battery until I installed iOS 5.1.


    A few days later I noticed that I was receiving excessive battery life out of normal use. The Usage counter would show the phones usage at almost the same value of the standby time which was completely wrong. I turned off all bells and still the high battery use.


    Some time after I was looking at the ipfw log on my mac and noticed that Skype on my phone, which was on the same LAN was contacting the Mac. I immediately thought this was strange as I hadn't run Skype on the phone for a while and all notifications were off. Skype wasn't even in a saved state in the task bar. So I had a look at the agents running on the phone with iStat and noticed there was a Skype agent running.


    So I deleted Skype app from the phone, did a full charge and disconnected. Since the phone has returned to pre 5.1 update battery use.


    I hope this may help others.

    Yeah So this is my first Iphone (4S). I have been an avid Droid user for years and always had great luck with them (battery, OS, ect). So I decided a week ago March 25th 2012 to take the plunge and get an iphone family plan with my significant other, assuming "what the heck, everyone says the battery life is the best thing about the phone". From day one this phone has been dog**** battery-wise. Not only is my phone affected, but my girlfriend's same model phone is the same exact way. So let me get to it already:


    I consider myself a tech-savy person and thought hey I can figure this out, man have I been wrong, along with 98% of 4S users. So the phone came stocked with iOS 5.0.1 I think. After suffering bad battery life for two days, with realistic/perfect charging to condition the battery, I assumed it was either a bad battery or iOS issue. I realized there was an update due for iOS 5.1 that noted bugs and fixes for battery issues. I proceeded to DL and Install once I had a full battery charge, while being plugged in. I thought to myself, "this is great, finally!" but to no avail; the battery life was still terrible... No Gain or Loss compared to before. Let me elaborate a bit...


    *Stock Phone out of box iOS 5.0.1 (03/26/12)

    -Day 1 with 100% charge, everything set to default, wifi off when not in use. I unplug from charger at 515am to get ready for work and lay the phone on my desk downstairs and continue to get ready for work. Leave for work and arrive at 7am, phone is at 88-90% (not even touched yet). By 12pm I leave for luch and I am anywhere between 35-40% on battery with on average 3 websites viewed and maybe, just maybe one phone call made. If I made it home at 4pm without my phone dying I don't remember.

    -Day 2 (same exact scenario for the most part)

    -Day 3 (same scenario) except this time I was proactive after reading about shutting off all the extra background services, apps, siri, ect, but nothing seemed to help at all! Literally if I saved 1-2% I didnt notice.

    *Upgraded to iOS 5.1 (03/29/12)

    -Day 4. Discovered update that noted bugs and fixes for battery issues and dove in as soon as my phone was at 100% charge. I thought I was finally free form the grips of this...nope. Everything back to default running on 5.1 I had no gain or loss in battery performance. I figured I would again try disabling all the background services listed before, but nothing would help. Sometimes it would drain a lil faster than other, but for the most part I was losing 10-15% an hour at least with the most minimal of use.

    -Day 5. I called Apple and their Sr. Advisor acted suprised, as if she hadnt heard of this issue really , and set me up an appointment with the "Genius Bar". Sooo I wait for that appointment hoping for a new update or patch to resolve this issue so I would'nt have to drive 2hrs to the closest apple store.

    -Day 6 and 7 resolve nothing other than reading forums and trying to educate myself on the issue.

    -Day 8. (04/02/12) I go to the Apple Store. The "Apple Genius" does a diagnostic scan on my phone and determines the battery and hardware seem healthy, but becomes aware of the giant loss in battery as we sat there for 10mins and it dropped over 10%. He was shocked  and said "this def is not normal". He proceeded with options, such as "I can wipe the phone clean and give you a new battery or I can just give you a brand new phone". I wanted to rule out hardware entirely so opted for the new handset replacement so I could start from scratch. So we moved forward and I went on my way back home with my 2nd iphone 4S with the original 5.0.1 on it. Charge conditioned it and didnt put any apps at all on it or upgrades. I wanted to see what the culprit was. It still was draining after giving it a lil use (10mins of soft web surfing and a 4min phone call). I seemed to be in the same boat again and dissapointed. I was right to feel that way because my battery issue was there exactly the same as before, except I had an empty phone I had to start all over with again...

    -Day 9. (04/03/12) Decided to upgrade new handset to 5.1 hoping for the best, assuming it really just needed that bug fix through the upgrade. Pretty much started my work day at 7am with iOS 5.1 on the new handset with no apps or customizations. Battery life still the same. I could not believe it, so again I disabled all the services listed before to see if it would help along with some other troubleshooting I read about over the weekend... Nothing would help. I could not find the culprit! Battery was still draining at an alarming rate.

    -Day 10. (TODAY! 04/04/12) Did my usual 7am-4pm workshift. While at work my battery showed signs of no hope once again, but I decided to get over it for a few minutes and finally use the smartphone portion of my purchase and redownloaded my apps one by one and see how the battery reacted; nothing seemed to help or hinder the battery life.


    So here I am at 8pm trying to help the cause by giving the steps I have taken. Sorry if I have left out important details, but I am exhausted over it, so feel free to reply with extensive questioning. My only hope is to shed some light for apple and its iphone users. Too many places I have read that people werent doing enough or were doing too much, which annoyed me because I could relate to every single one of the issues and I know you guys can to. So enough from you guys who say try this, try that, stop using the phone so hard, swap it out at apple, upgrade, restore from itunes, restore from scratch, put it in the oven, put it in the freezer, because NONE of that has worked for me on any level as of yet. Same for my girlfriends phone. None of these steps have helped my battery life and I know there are other in the same boat which is deflating.


    Currently my iphone 4S is a white 32gb with iOS 5.1 installed.

    I am on Sprint and generally have 4-5 bars of service all the time, including 3G.

    My serial number is starts with DQGH12V*****

    Model MD246LL

    Version 5.1 (9B179)


    Let's crush this rediculus issue that has gone on for far too long.




    Okay, Important realtime update!


    -Day 11. I went to sleep last night at 1030pm with my phone unplugged at 93% and just woke up at 515am to grab it at 90% and currently at 6am it is still at 90%, this is huge for me, but actually realistic...


    What did I do different? It it basically in tandem with what a few other dudes were saying on here: the 3G.


    I looked on Sprint to see my coverage area (work and home) and it looked good, I am even two houses or so down from excellent service. That said, my phones service bars and data service reflect that considering I get pretty quick upload and download speeds.


    So to the difference:


    Location Services: ON

    System Services: OFF (not that this should be a factor because it never helped before)

    WIFI: ON

    Cellular Data Services (3G): OFFFFF!!!!

    -Nothing else dissabled and bam.


    So with the culprit pointing to the 3G antenna I am going redirect my focus today, but this is the only positive feedback I have been given in the 10 days I have been hammering away at this phone. Apple needs to put us on their payrolls for this?


    With all that said, I have not been able to get any momentum the entire time whatsoever with any troubleshooting tactic until now, with just turning off cellular data (3G). I am even running WIFI and tons of apps to push the phone a lil and it isnt budging battery-wise. Like other have said, this def doesnt "fix" the issue , but it is a slight work around that will set your battery life back to the stone age of good batteries.


    Go ahead:

    Setting>General>Network>Cellular Data (OFF!)


    Now this is redic considering your biggest monthly cellphone plan cost is generally your data, but it seems to me it's better temporarily than to have a totally dead phone.  I am pretty sure apple has installed some shotty antennas in some of the handsets that is constantly pinging the network hard and it probably has something to do with iOS 5 being 4G ready... This is EPIC FAILURE for this company I think. I think they know it to, but like the original 4S issue it should get solved, but I am sure the flawless iphone 5 will come out then, since they seem preoccupied by it rather than fixing this issue within 6-7 months. I can only hope they knock off $400 dollars at trade in with this phone for the new one at minimum.


    Hit me with any other questions.


    Another update!!!!


    Thanks, I only want to get to the bottom of this like everyone else...


    Another side note. I decided to turn on cellular data (3G) about 5mins ago at work, since I don't have wifi, to see how'd she hold up. Keep in mind I was at 89% at 7am when I arrived at work. I am now at 81%. I dropped 7% in 5mins with cellular data turned back on. This is def the main issue by far.


    Any thoughts?

    I honestly feel as if they battery just needs break in time. When I first got my 4S (4 days after launch) the battery was draining insanely fast. One of the times I lost 30 percent in standby by over night. My battery stats now are generally about 21 hours stand by, and 5 hours 30 minutes of usage. Which is is enough for me to squeeze through a full day. I don't charge my phone over night either, and I'm always at 100% when I wake up (it's in standup for about 9 hours while I'm asleep) so personally, after a few months I think the battery gets progressively better.


    My setup is:

    iPhone 4S 16GB on AT&T


    Raise to speak Siri OFF.

    All location services that I don't need OFF

    Timezone setting, iAds, and diagnostic and usage OFF.

    Brightness always 100%


    That's the only notable things I could think of sharing. Hopefully this helped you out a bit.
