    I have an iphone 4, which has just been restored. Using iOS6, I get a full day of usage with about 1% drop overnight (no use) after a full charge. 

    With 6.0.1, I get a 95% drop overnight. My phone is on GPRS - there is no mapping etc. All my other iOS devices have similar problems. My iPad 2 is no longer capable of a full day's travel at work.

    As a CEO, my staff can't function properly with a device whose utility has been reduced by the manufacturer.

    What I find particularly disturbing is the lack of:

    1. any explanation from Apple (whether it knows what's going on or just is choosing to ignore it).
    2. suggestions on how to improve the situation temporarily (thanks to many on this site for trying hard on both counts)
    3. an acknowledgement that this will be fixed in the next update - even to provide a setting that allows the user to turn off the culprit process/function.

    Is anyone or group able to progress this?

    Hi Leek,

     

    Yes, you should not constantly bring your phone down to 2%, 1% before recharging it. You are depleting the phones capacity to retain a charge quicker then it should. Remember, the iPhone battery can do about 400 "Full' charges and when it hits below 20%, battery saving protocols are enacted in the phone. I got crash logs on mine when tested them here which indicated issue on the power conservation actions against my user set up. Id say Apple has that one well in hand as it is so obvious. The other issue of constantly flattening the battery before recharge is that you are decalibrating the battery meter.

     

    A sign of over or under charge battery damage will be when the phone is fully charged with the plug avatar instead of the lightening avatar beside the battery % and the battery % is at 99%, 98%, etc, etc. This real battery damage due to the battery starting to deplete as designed is skewed by the constant flattening of the battery where you will get a similiar reading much earlier due to the battery not behaving like its designed and the battery meter becoming decalibrated. The remedy to the latter is doing as I did with one full charge (recharge fully when at 20% remaining( and then three part charges (recharge fully when at 80% remaining). It restores the battery to full potential.. If it doesnt show improvement after 3 charge rotations, then some thing else is wrong, maybe battery damage which in an aged phone is normal due to the battery lifecycle of 3+ years on average, but not normal in a new one obviously. If you can get into the habit of 1 full charge to every 3 part charges fully charging your handset every time, you will bring your battery to its full potential elongating its life compared to our fellow iPhone users whom flatten the battery every time before recharge.

     

    Hope this helps

     

    Best Regards

    Hi 85, I should have qualified my comment -61db being aweful if your background noise is high. There are two main components in signal receiving and transmission Signal and Noise. Noise is the background signal traffic, interference, etc that clouds your signal transmission (a bit like long grass growing over your path in your garden obsuring your sight of the path) so if your Noise levels are high like mine when you have a low Signal to Noise ratio (aka SNR) which makes for a poor cell reception making your phone work harder when it should to get a signal. If you are getting -50db or higher (to zero) when id say your signal strength was titan and good to go and with reasonable noise levels provides a very good cell reception. However, as you are getting 4 bars on your phone and have a signal strenght of -61dB, I can only conclude your SNR is good as your noise levels are low enough to enable good cell reception.

     

    I hope Im being a bit more clearer now. Apologies for my last post as it was nearly midnight here when I wrote it.

     

    Best Regards

    @ 85, this happens to me and can be explained by being on the periphery of a cell tower broadcast where you may be switching between two towers depending on whos signal is strongest. There are other reasons that feed into it aswell, time of day, usage, etc.. .this will alter signal strength in concert with the tower set up format in your area.

     

    Hope this helps

    Best Regards

    @Gamechanger, if you are upgrading your companies iPhone 4 to iOS6 and they are eating battery life, then it can be a number of things and most likely in your handset set up. I would wager through that the default settings for iPhone 5 on your iPhone 4 are interfering with your handset and signal requests are being made for synching purposes and/or transmission of data. I would do a little rule of thumb test before calling apple by seeing how much mobile data your phone has used through Settings/General/Usage/Mobile Data(at end of page). If its way above what should be, then you know your set up is incorrect and the system is looking for data unneccessarily which brings me to your user interface with your company VPN/Email etc. You need to get your tech to talk to your business tech advisor at Apple to get a trouble shoot on this as the data behaviour on iOS6 and signal usage seem linked in certain set ups when it comes to battery drainage.

     

    Finally, review my own post on my set up and see what I turned off as unneccessary. If you feel the same way, then do so on yours to maximise your phones battery potential but not to the cost of desired functionality.

     

    Hope this helps

    Best Regards

    @john mul

     

    By the way, do we perform this charging cycle on a daily basis or we just have to perform it once a month?

     

    Thank you

    @Leeck, excellent question! I would say that you should do that always and in particular when the battery is not performing well on cases where it doesn't reach 100% fully charged. However it's hard to be always focused on your iPhone so I would recommend doing 3 full charge rotations at least once a month and no later. If you note a 99% full charge within the month, then I would engage the 3 charge rotation immediately...

     

    Hope this helps..

     

    Best Regards

    After upgrading to iPhone 5 from iPhone 4, my battery life has been almost exactly the same. The best usage I have been able to get was 5 Hours 43 mins with 1 day 3 hours standby. Never been able to breach the 6 hour usage mark. I did a icloud restore when I bought my new phone from best buy. it is production week 39 build black 64 gb verizon. I have done various tests using LTE or only 3G and results are pretty much the same. I can live with the 5 hours because I usually charge it at night everynight anyway, but I do admit I am getting jealous of some reporting 8-9 hours of usage! Not sure if it is some kind of app that would cause this drain in the background, I tend to close all my apps when I am done using them. But my iPhone 4 had just as much battery life after 2 years compared to my brand new iPhone 5

    This is rediculous.

     

    I forgot to bring my charger to the office. As a result I'm afraid to even touch my phone. No playing games during lunch or surfing the web or listening to music. No nothing. Because I won't be home until later this evening and I'm expecting a few calls.

     

    This is. Ridiculous.

     

    And you can say what you want about smartphones and their battery life; I have owned plenty of smartphones over the past few years including iphones and never have I experienced anything like this.

     

    I hate you Apple.

    There. I said it.

    You need to take into account the explosion of smart phone use too.   Alot of the existing infrastructure was designed for voice traffic and simply  can't meet the demands of the users. Apple doesn't exist in a void here, ALL phone manufacturers build their products to meet the industry standards and all have the same challenges.  The carriers have a role to play here too, and are working to keep their networks updated to meet the ever increasing demand for services. Until the carriers update the networks or technology improves to help manage power consumption, smartphones  will be at this crossroad right now, either thin or light or built with batteries with higher capicity with the associated trade offs.

     

    Buy a cable or two and keep them at work, the car, etc.  It's a really a small price to pay to being able to move past this annoying, but small issue.

     

    my two cents

  • KéKé Level 1 Level 1 (0 points)

    A cable or two will put me back 50 bucks! That's hardly a small price to pay after shelling out the initial 900 bucks just to get the phone. I say boo Apple for saying up to 8 hours 3G surfing and only being able to keep my phone alive for 4,5 hours MAX.

     

    I say boo Apple and I'm sticking to my guns. I will make sure none of my friends or family will even consider buying this overpriced paper weight.

     

    Apple is dead to me. You hear me Apple?! I want a divorce!!! You can keep the kids.

    Could a whole series of issues, try the above link to see if anything there helps.

     

    If your company uses activesync then the below is worth a read.

    @KeKe,

     

    You can fork over the money for some cables, or you can return the phone and get something else.   You will never see APPLE admit the problem to the public.   Only the very worst issues get some comment out of them and like it or not, this is not a universal problem.

     

    I'm afraid there is no quick fix on the horizon either, as anything they do to improve power management enough to make everyone happy, will almost certainly have a negative effect on other aspects of the phone's performance.  

     

    Maybe iPhone 6 will have a bigger battery.   THAT, IMO, is the only real solution to this issue.   More battery capacity.

    Something I don't understand with the way the usage and standby minutes are calculated.  I kept noticing that my usage and standby mins have always remained very close, but lets say I unplug my cell from the charger at 7am by 1pm I am seeing approx 6 hrs of usage and 6 hrs of standby time listed in the usage statistics.  Am I missing something shouldn't the usage and standby hours added together equal no more than the total time it has been unplugged (7hrs)?  I have attached to images that demostrate my point.  They were taken on the same day roughly 1 hr 10 mins apart.iPhone Usage Stats Screenshot 1.PNGiPhone Usage Stats Screenshot 2.PNG
