    I guess you are somewhat correct, not sure anything is proven by this write up. But it stands to reason that if a few settings in a certain plist file is all thats needed to "solve the battery issues", dont you think Apple engineers would have already done so and sent out 5.0.1.1 by now? If  for no other reason than to hush the complaints on their support forums. I am just weiry when some hacker posts some fix to an ongoing well know issue and all you need to do is send $5 and you too can have it.

     

    Actually, I have a fix for the battery issues as well and if you send me $3 I will email it to you. Thats a $2 discount!

    If she is on wifi and you are not that will make a difference.  6hr 3g verses 9Hr wifi  as far as spec. Plus is there a difference in apps on each device?  Lastly have you restored from a previous device or running a default out of box setup?

     

    Wait also your starting points are not the same either. It appears that the 100% to xxxx takes longer than once you drop down a little. I mean the meter does not appear to be linear on the iPhone 4s or iOS 5. It can sit at 100% for a while then all of a sudden drop then drop more. Unfortunatly the battery meter on iPhone does not appear to be very accurate. So in reality, I would have them both charged to 100% then compare over the same time period and see the results. That would be a better comparison while still variables due to types of usage, installed apps,settings, batttery calibrations performed etc. Sorry dont mean to nitpick but really a comparison between two phones need to be a bit more even steven so to speak for true results. If you do further testing do post back with those results.

    Okay i definitely have faulty iphone. My partners and mine were bought a day apart. Mine has been on 2hrs less than hers today. She has been on facebook and internet, calls and texting on hers. Dropped from 100% to 69%. 31% lost. From 7 to 18.48.

     

    Mine has had ten mins of calls all day down from 87% to 30% in the same time period. Mines lost 57% from 8.45 to 18.48.

     

    Both are 32gb both with os5.01

     

    Now heres the intersting bit, hers had location services and wifi switched on all day, mine has had both switched off. So despite mine having the bits that use alot of battery power switched off its still consumed more power, go figure!!!!

    She has more apps than me on hers, i have facebook and twitter. She has those two plus many more.

     

    Both are on charge now. When they are both at 100% i will switch my wifi and location services to make it like for like and leave them by each other and see how they go. I will leave them all night and see.

     

    Will report back tomorrow! Now time for the gym! Argghhh

    The reason why Apple is neglecting this problem, is because there isnt any fix. This proves that it is a hardware issue and the device needs to be replaced asap. Authorized apple providers may say the wetindicators are triggered and the warranty will then not be valid. Its a common excuse. I am going to return my 4s and will instead invest in android.

    Well, I hear you that it wouldn't make much sense. On the other hand it may just be that Apple have other imperatives/constraints that the hack community has not - like stability, or performance, or integration with other software components that require either. Further your statement assumes that all the changes made are the ones exposed in the .plist file. Another aspect of this whole ordeal is that actually the 5$ was merely to gain access to their beta repository, as they claim - whether ex post facto or not - that when they're done testing it it will be released as free. Of course they must have known that in context it would all amount to the same thing because of the high demand for such a fix. But personally I'm as much suspicious of the Cydia crowd as I am of the cultofmac/wired crowd. It seems in this world you have to make your own opinion about these things - unfortunately it's time consuming. It's a lesson I'll always remember as when I was young the astronomy books spelled out that Pluto was a planet - whereas it is not. So I wonder how many more "approximations of a truth" I have been fed over the years. I'm also very much on the lookout for fallacies in logic reasonning, as when someone says "no documented case shows that X is valid - therefore X is not valid" - which is just as logically bad as saying "you cannot disprove X, therefore X is likely".

     

    As for your fix, as you well know, I don't have any battery performance issue to resolve

    I've heard a lot of complaints about the battery life, but what exactly is considered as normal battery life for iphone 4s?

     

    2%? 4%? or 10% average battery loss overnight (8 hours) on standby? anyone?

    The iPhone 4S specs are listed for 200hrs standby hours, so that means 0.5% per hour on standby, but auto-checking of email and what not count toward usage and can happen while you're not actively using the phone i.e. 5 mins mail fetch, apps that have the ability to poll the network even when they're closed and other undisclosed things. So it varies with the setup you have (mail, apps, etc.). But some people have 0.5% per hour standby drain... so at that rate you would lose 4% for 8hrs.

    The 3G switch will make the difference. Mark my words

    Another few threads have indicated that the diagnostics and usage setting  being turned on has caused the no service issues but also is behind battery drain. Apparently thats part of the network hang up I mentioned earlier where when loss of signal then diagnostics tries to send over and over.  I have had that off forever myself so I cannot confirm but you guys may want to try that if you haven't. Just throwing it out there in case you have missed it. See below

    hello eveybody. i have the iphone 4s since almost 3 months and since day 1 problems started, losing network, no service, sim failure and battery draining. and since day 1 i was trying to find a fix. after contacting may carrier they told me that it is a software-hardware incompatibilty between the 4s ios and the sim card and the network signal frequency of the carrier company. and i had to wait untill the new sim cards are produced. Meanwhile i was using another carrier company sim cards and my iphone worked much better. after that apple released ios 5.0.1 (9A406) so i returned back to my old carrier sim card and it worked good but some problems remained. 3 weaks ago my carrier company delivered the new sim cards although my phone was working fine. but for curiosity purpose, i tried to install ios 5.0.1 (9A405) again using the new delivered sim card, and no problems showed and i was able to call and text anytime. so i discovered that the no service and the no sim errors are generated due to sim-ios incompatibilty. but the battery draining and the latency in recovering the network after moving from a low coverage area to a good coverage area remained, and everytime i went into the elevator, underground, or any place with low coverage area, i lose the network and no service appeared "wich is normal" but if i go back to a high coverage area, the no service message remained for almost 10 minutes minimum "wich is completely not normal". more investigation about this problem and contacting apple bug reporting service and lots of trials, i discovered that this case is the main issue and it is behind the battery draining. Simply it was the diagnostic and usage reporting. whenever u enter a low coverage area, your phone loses network, causing an error generation, so your iphone tries to send this error message to apple server while you are without connection, it tries again and again and again without success, so the os shuts down the process of sending the error report and the network reception shuts down " you can simply monitor the procedure by installing the configuration utility from apple website " and monitor the configuration log where you can see the process happening untill shutting down the carrier reception retrievel function. so the solution and only solution was to turn off the diagnostic and usage sendind data automaticly. and after doing that, battery and no service error completely fixed.

    SO TRUST ME THIS IS THE SOLUTION AND FOR BEST RESULTS

    - ORDER LATEST SIM MODEL FROM UR CARRIER

    - INSTALL IOS 5.0.1 (9A406)

    - REMOVE SIM PIN

    - TURN OFF DIAGNOSTIC AND USAGE AUTOMATIC SEND

    - USE YOU PHONE UNTILL BATTERY DRAINS AND SHUT DOWN THEN RECHARGE TO 100% "to refresh it and calibrate it"

    Wish u good luck and let me know your feedbacks.

    I posted earlier and thought it only fair I update on my situation.

     

    My battery drained from 100% to 1% in about 10 hours stand by with 5 hours usage (i was sleeping, so I didn't use the phone for those 5 hours). I noticed push email wasn't working this morning (emails not arriving) so rebooted the phone and it's now fine. Battery is 87% after 9 hours of standby. So I'm pretty sure something went wrong with push email during the night and drained the battery down. The only other thing I did was switch the flash light on for a few seconds last night out of curiosity. Otherwise, all other apps were shut off and no location services. So culprit was either push mail, or turning on the light.

     

    Thankfully i'm back to normal.

    whe want 5.1 UPDATE PROMISE BY APPLE SINCE NOVEMBER (sent to developpers)

     

     

    i think it wil never happens..........apple sold 35 millions in octobre to end of 2011. (3 months)

     

    and will sold 100 millions minimum  when the IP 5 with 4''screen and 2000 mah battery will go out at the end of the year (or middle).

     

    People have forgiv ang have little memory.

     

    IP4S??????????????? it their mind it is a thing of the past and present..........

     

    their energy are in the IP5.

     

    if whe would   have a update......whe would have it many weeks ago.

     

     

    is that update will give us 25-30% more juice. impossible..

     

    ANYWAY a A5 processor with all options(IOS5) and with all that energy SIRI want  the ip4s need a 1900 to 2000mah

     

    whe have to turn a smart phone in to a flip/flop phone.........2011 flop of the year.

     

    have a good day guys

     

    Flop?  Have you seen how many have been sold?  55% of all the phones Verizon has sold in the last quarter?  And that is for only 3 basic models, 5 if you count the 32 and 64M 4S.  I rather suspect ANY other company would just love to have a 'flop' like that!  And not a lot of people have battery troubles, the ones that do just seem to assume everyone does.  Misery, as they sav, loves company.

    Come on what's the trick for that.

     

    My phone is currently on 34%, was on 43% at 14.30. 2h 25 since the reboot as instructed. 9% in 2.5hrs with no usage whatsoever.

    Reset phone (settings and data).  Don't restore from iTunes, just sync everything.  Then try again.

    Your opinion.  For some, there are hardware issues.  For others, it appears to be a form of corruption of the data restored from an old phone, or a SIM moved from an old phone.

    Nothing changed about Pluto.  It is still there, still the same size, still **** cold, and still in the same anomalous orbit.  Someone just decided not to call it a planet any more.
