4.2 occasional rapid battery discharge warm phone

(I have had this 3GS phone 32 GB 4.2.1 (8C148a) since last spring and since the latest update I have had it discharge itself very quickly and be quite warm to the touch twice the first time was about a week after 4.2 was on itunes to update and I did all the things recommended in the FAQ (no nee to restart as it was so fully dead it did that by it self when plugged in after a few min but re update and restore etc it was ok till today when it did it again now both times this was when using just wifi 4 or5 balls from ATT all day and less than 5 min of actual phone usage and perhaps 5 min of app usage push and blue tooth are off. phone went from 100% to 0 in about 4 hours I normally go from 100% to 75% or 50% over 12 hours depending on usage that day
I see plenty of reports of this sort of thing in this forum from last year but nothing much recent and no real fixes other than the standard restart and restore is this just an endemic problem on the 3GS that we have to live with?

There are several other threads out here about battery drain issues. Please look around...If you try all these other suggestions and are still having drain issues, restore as a new phone, and don't add anything back yet. Just browse web, youtube, maps, txt, etc for a while, as well as standby...Let it go for as long as possible, and see how your battery holds up. If it's not ok at this point, then do a DFU mode restore. Google around for instructions on that...If that still doesn't fix it, then I'd say it's a trip to the Apple store for you...If this fixes the issue, then add back ONLY 1 thing at a time. Mail first usually, and watch for a while to see if it drains again. If not, proceed to next item(apps 1 at a time). After each added item, watch for a while to see if it drains ok. Should be able to narrow it down to the culprit. I know this takes quite a while to accomplish, so patience is needed, but as has been previously stated, it's usually bad or corrupted data in a backup that causes this...I had posted in another thread of same issues here. I was fine after the 4.2.1 update for quite a while(enjoying almost 3.1.3 battery life), then for reasons yet to be determined, mine started draining. Had this same issue with 4.0 update...I went into Settings where the Tethering item is located, and it was constantly clocking on that. Usually it clocks for a few seconds, then says Setup Tethering. Well mine was stuck there, so i think it was constantly using something. A hard reset cleared it, but I still have to try and figure out why it did that. I just don't have the time right now. I will most likely try as restore as new phone at some point. Apple did something though, because like I said, I'm enjoying almost 3.1.3 battery life now. I think it may have to do with cell radio, as I've seen something about NCFD being supported now in 4.2.

  • Intermittent rapid battery discharge

    Hi,
    I’ve occasionally had my battery discharge in a matter of hours from a full charge.
    I always dock the phone for sync and recharge overnight. Maybe 5 times now in it's 5 month life, it has completely discharged by noon. (usually, I’ve got 70% remaining by 10pm.)
    A couple of times, the phone was noticeably warm. Today, it didn’t feel warm, but it was half discharged by 10:00am, and 10% by noon (without using safari, or mail for more than 10 minutes, and not using phone at all).
    This has happed with, and without Wi-Fi enabled. In fact, I turned Wi-Fi off when at 50%, and even powercycled, and reset the phone, and it still was sucked dry.
    Anyone experience this before? Any insight whether I’ve got hardware problems, or is it a mode that the phone hangs up in?
    Thanks

    I had the same problem, and I do not have a Yahoo account. Took it to Apple Store, told me it was a software issue. They had me do a full restore, and leave the phone without any data on it for one day to see if the problem happened again. (For me, it wasn't intermittent, it was happening every time I charged up) Believe it or not, that was the answer. I haven't had the problem since. The guy said the software gets corrupt and tricks the phone into thinking the battery is dead when it really isn't. Go figure.

  • Apps close fast, battery drain, warm phone, wifi...the issues go on

    For the last couple of weeks, by iPhone 4S has been running warm no matter where I keep it.  In addition, when I open an app, it may or may not open.  When it does open, it quickly closes almost immediately.  It is like trying to beat the clock to type a text or use any features.  My iPhone will also not hold the battery charge.  It drains to 'dead' within a few hours, if that.  The Wifi connection is spotty, too.  Recently relocating from California to South Korea, I can use Wifi in my neighborhood, but when traveling to another town, it works intermittenly.  When I try to sync my phone to my laptop, it often does not complete a sync, but will restart if I barely touch the phone when it is trying to sync. And, somehow, since the new OS install, my app store on my phone is all in Korean.  Not sure how to change this back to English.  Everything else on my phone is in English.  I have to go into my iTunes on my computer to download any of the appupdates since this is stil in English.  My settings are all set to English.  I have barely had this iPhone for one year, receiving it in early October, 2011. 
    Whille I was briefly home in the States over the last 6 months, I visited the Apple stores quite often as there are many glitches when you are using a pc laptop with Outlook 2010 & trying to perfectly sync with the iPhone.  I hope soon to invest in a Mac.  But until then....
    This battery/app issue has happened in the not so distant past.  Returning to the Apple store, the Apple expert did end up saving all my information, erasing my phone & reinstalling everything.  It took forever & I lost all of my settings & personalized stored data in my apps.  I really hope there is another solution to my current crisis. 
    I hope to hear from you soon as this situation is quite frustrating. 
    Also, can I Skype with Apple support?  A phone call costs $2.29 a minute (no matter who calls first).  Besides, I am not sure my phone will hold a conversation right now. 
    BTW, I did install the new OS recently, too.
    Thank you for getting back to me asap...

  • Battery discharging while phone is off

    My htc incredible 2 is losing charge while my phone is off. i charged it completely yesterday, then turned it off, now 12 hours later it wont turn on until i plug it in the pc to charge. and when turned on the battery is almost completely dead.....Any ideas?

    I have to respectfully disagree with you about the Advanced Task Killer. Everytime you are killing an application, it will just cause the application to respawn themselves.
    Try this application instead.

  • PRS-650 - Rapid battery discharge.

    My reader worker perfectly until a couple of weeks ago. Now it discharges from fully charged to dead in a few hours of non use. It does not seem to matter whether it is in sleep mode or shut off completely, when I go to read my book it is dead.
    Very upsetting. Anyone else have this problem?
    Solved!
    Go to Solution.

    I am also having this problem, but with a PRS T1 model. My reader was a Christmas present and that particular function has not been an issue until last week. I have experienced all the other issues that have een posted but the last firmware update solved most of them. Sony, what is your solution to the failing batteries?

  • I have just updated my 4s to IOS7. and now my battery discharge is significantly increase. With my Iphone fully charged, the battery run out within 6 hours without using the phone at all. Would it be possible to get the IOS 6.1.3 back to my 4S?

    Hi, thanks for the suggestion. I have tried as you suggested, and when opening the "purchased" apps some have the icloud logo next to them, but I only have "OPEN" against "Find My iPhone". When opening it up, it goes through the same routine; needs to be updated before proceeding, and wouldn't update because I don't have IOS8.
    Anything else I could try, or am I doomed!
    All of your help is much appreciated, thanks

  • Why is my battery discharging so rapidly after iOS 5 download?

    Why is my iPad1 battery discharging after iOS 5 download?

    It is not just you - something is wrong...
    I noticed a significant difference.  Normally my iPad 2 would sit in my bag overnight and drain just a few percentages.  Now it drains almost completely.  I have turned off all services, fetch, location, etc - it helps a little, but the battery life is worse than before.  When using my iPad 2 during normal usage, I could get through a couple flights and still have more than 50% battery - now I am lucky if it makes it the same time before getting to 0%.  Something is wrong with the new iOS 5.  I wish I wouldn't have updated...

  • IPhone battery discharges even when turned off since iOS 5.1.1

    Since updating to iOS 5.1.1 I have had battery problems, discharging at around 4% per hour even when not used. Turning off every concieveable service and reloaded iOS as a new device unfortunately has not solved the problem. I have resorted to leaving the phone plugged in all of the time and recently started to turn it off overnight. To my surprise, the phone continues to discharge when turned off! I couldn't find this problem when I searched (apologies if I didn't search hard enougth!)

    I have been waiting for months for the next iOS to see if it would rectify my battery drain problem but I continued to have the battery discharge problem after installing iOS6 .
    My Home button has been playing up with random no responses and random double clicks, so I replaced the home button hoping that may also address the battery drain issue - no joy.
    Then I had a look to see if I had added any Apps when the problem first appeared at the time of upgrading to iOS5.1.1. (You can view Apps by date in iTunes on the iPhone Apps tab.)
    It turns out that on about the same day as the iOS 5.1.1 update I also added the Lifesize ClearSea video conferencing App. Today I disabled the App in iTunes (unchecked it) and resynced the iPhone. I believe this removes the App from the phone whilst leaving it in my iTunes so I can add it back easily. For the first time in months my phone is now cold rather than luke warm.
    Superficially at least it seems that ClearSea has been running in the background, even when manually quitted and even when the iPhone was powered OFF! I will report back in a few days to confirm this was the culprit.
    Five months with a phone that barely lasts a day has been a real pain...

  • Nokia 6300 Battery Discharges too early very fast

    I have bought a Nokia 6300 from Karachi Pakistan. The battery discharges very faster than the normal battery discharge time under normal temperature n conditions.
    Need solutions as soon as possbile.
    EDIT: removed personal informationMessage Edited by mohjo on 20-Apr-2007 08:10 PM

    Yeah nj7_ i'm craving for that setting.Unfortunately,brightness adjustment isn't present on Series 40 V3 phones We're still waiting an answer from Nokia.AFAIK,previous series 40 v2 phones had this setting..eg N5140 and N5140i.
    Factors that can drain the battery fast on N6300
    -16Million colour display
    -It uses a BL-4C 820mah(Which is kinda insufficient)
    -The screen is very bright

  • HT4623 Iphone 5 battery discharging too quicklu

    Iphone 5 battery discharging too quickly, even with wifi, bluetooth and location services off. The battery is only lasting about 6 hours.  How can i check what is causing this.  It was lasting about 24 hours before.

    Just shared. Turn your brightness To as you can see The page. Turn of icloud if not use it If you just buy this phone. Let the battery totally drain couple of time and fully charge again. It will became great after that.my phone take 2 days to totally drain.awsome. If your location to far away from network transmitter it will became little bit hot at the battery.if you very near to wifi you will feel  your iphone5 it surf like a ferrari + no heat at all.     P/n; dont look at pecentage of your battery. Just take note how many hour until its totally drain.

  • IO6 battery discharges quickly and every time I open an application, it crashes and closes

    I upgraded to iOS 6 and since then the phone battery discharges quickly and every time I open an application, it crashes and closes. And finally, back to the home screen. I can not send messages, listen to music. And when my friends call me, the link is silent and then back to normal again and then is silent. Can anyone help me? I have an Iphone 4.

    Restore your phone as a NEW device, not from backup.

  • Stop led when the battery discharge

    when the battery discharge i my macbook 13 i don't see de led that it indicater the stop state. but when i connect the power source it returns on my last job. it's normal?
    excuse me for the language....

    Thanks - but it is not that simple. the sim cards are in the right phones. my phone recieves calls most of the time, but if it not available then my wife's phone picks it up. we have turned off blue tooth and hot spots and turned phones on and off and this seems to temporarially solve the issue, but then it reoccurs.  it did not happen immediately after her sim card  was in my phone - it is more recent.  we do not have call divert on.  it is just odd.

  • HT1222 i have low battery indicator when phone has been charged

    i have a low battery even when phone has been charged

    Battery meter recalibration...
    Fully discharg (until it shuts off) and then fully recharging (don't unplug until 100%) to recalibrate the battery meter.  You may need to do this a few times.

  • IPhone 4S battery discharging Way Too FAST

    Hello,
    to my utter disappointment the battery life or better the life of a charge of the iPhoone 4S battery is deplorably short. I have read all the negative comments and I had been forewarned by the salesperson that the this might happen (he works part time for the phone company that sold me the phone and part time freelances setting up iPhones for corporate use. And in his experience battery life varies greatly depending on if the battery was treated correctly at the factory, what version battery it was etc. And in his opinion the quality of the components Apple builds into it's hardware (harddrives, batteries etc.) are not cutting edge at all – as one might expect taken all the hubbub Apple creates around it's products – but cheap run-of-the-mill stuff.)
    So, I feel a lot like Apple does not live up to it's self-created reputation and standards of delivering top-notch hard- and software – for a hefty price, that is.
    I have disabled as many of the location-based services as possible, only activating them as needed. I have turned off any and all of the auto-update, selfcheck, -connect etc. features. I do not receive emails, I do not Twitter, Facebook or whatever Social Media stuff to save energy. Still, the battery discharges at a ridiculously fast pace. E.g. a reminder message (displaying on the startup screen as soon as I unlock the iPhone – unused all night): 25% of the energy level is being used up by that. A lot of the fancier apps using location based services or GPS apps are depleting the battery within an hour or even less (hiking, biking, jogging appps). So a lot of the much vaunted versatility of the iPhone falls short for me because I cannot use those apps without wasting too much energy.
    As I said before, I am very disappointed!

    We've been to the Verizon store on Mary Esther cutoff in Ft Walton Beach three times now. The first time they said to make sure no apps were running and eliminate those we didn't need. We did that. The second time we were met by a person who told us no one had that problem and it was Apple. The manager then came over and was very nice, suggesting we try to backup the phone to our laptop, reset the phone to factory, and restore. We've done that three times. We've also tried renaming our router access point twice.
    We go today and tell the female rep that we still have the issue. She says no one at Verizon has ever heard of it and there's nothing they can do. I ask if we could get another phone since it was under warranty (April 10 was our anniversary) when we first brought it in, or replace it with the insurance we pay $8.18 per month for. She said no on the warranty, and sure for $169 deductible. She threw it back on Apple. Clearly not happy customers. If I didn't have a year left I'd be swapping providers today.

  • Battery discharge: Lion 10.7.2 vs Snow Leopard 10.6.8

    Has anyone noticed that Lion consumes more resources than Snow Leopard thus causing faster battery discharge?
    YMMV, but it would be interesting to see of others can get similar results. Do you suppose Lion 7.3 will increase or decrease resource usage and what affect will it have on battery life?
    I called Apple about the battery discharge issue on my 2 week old MacBook Pro with Lion 7.2. I was only getting about 1/2 of the 7.7 WIFI hours advertised. They gave me the usual "if depends" on WIFI, system settings, applications, etc., i.e. such things as cpu and memory load (paging/swapping=>disk i/o), other disk activity, and a few other things.
    My large expenditure on the new MacBook spurred me to investigate what was going on using the Activity monitor. I configured my old MacBook Pro (mid 2009) and my new MacBook Pro (late 2011) with the same system preferences. I reset both the PRAM and SMC on both machines to maximize the battery charge (documented elsewhere).
    Obviously, a direct hardware comparison would not be meaningful but when you look at the operating systems there is a significant difference between Snow Leopard OS X 10.6.8 and Lion OS X 10.7.2. Lion uses much more resources than Snow Leopard.
    My Observations:
    The first value I list is for OS X 10.6.8 and the second for OS X 10.7.2. I tried numerous other combinations but these nicely summarizes my results.
    1) I started with only the Activity monitor, iTunes Helper, and Epson EEventmanager manager running, No WIFI or any other user processes
    CPU % idle               : 98.75 vs 99.4 (i.e. both machines were literally idle)
    No. of threads           : 179   vs 277  --> + 55%
    Kernel threads           : 60    vs 82   --> +37%
    Processes                : 41    vs 54   --> +32%
    Wired Memory MB          : 480   vs 864  --> +80%
    Active Memory MB         : 198   vs 407  --> +106%
    Memory Used  GB          : 0.808 vs 1.32 --> +63%
    Percentage of 4 GB       : 20%   vs 33%  --> +65%
    Virtual Machine size GB  : 96    vs 149  --> +55%
    2) With WIFI and Safari added
    CPU % usage              : 72.9 vs 91.02 (i.e. both machines were not very busy)
    No. of threads           : 253  vs 376 --> +49%
    Kernel threads           : 60   vs 82 --> +37%
    Processes                : 51   vs 63 --> +24%
    Wired Memory MB          : 669  vs 1007 --> +51%
    Active Memory MB         : 600  vs 1190 --> +98%
    Memory Used  GB          : 1.57 vs 2.47 --> +57%
    Percentage of 4 GB       : 39%  vs 62% --> +59%
    Virtual Machine size GB  : 131  vs 191 --> +46%
    Look especially at the percentage of memory used. In either case, I measured no paging nor swapping. But, as you can see, with the increase of memory used with Lion when WIFI and Safari were added you could quickly push the memory as more process are added and start paging and swapping to/from disk hence use more battery charge.
    The increase in number of threads, processes, memory usage, virtual machine size, and WIFI activity would imply that Lion would have to consume more battery charge than Snow Leopard as you use more cpu/memory to chase more threads.
    I looked at WIFI usage and it involves a lot of chatter between the computer and the internet. Over time a lot of packets are sent/received even when no data is being passed and would be a drain on the battery. There would be a greater drain when there is data passed because of the additional CPU and memory needed. But, in todays world, you cannot run without an ethernet or WIFI connection because of the dependency on the information/data on internet cloud.
