    I found certain dependence between iCloud and standby time, maybe it will help for someone. Moving back and forth between different solutions to improve my iPhone4 battery life I've noticed that stanby time dramaticly reduces after enabling backup to iCloud instead of iTunes. In this case I have only about 16 to 18 hours of standby in my normal use. If I restore my iPhone, set it up like a new one and then restore from iTunes backup (backup to iCloud is disabled) - then I get about 24 hours of standby with the same use. I tried this trick several times and always got the same figures, so I guess this dependence is true: backup to iCloud reduces standby time.

    Dear Experts

     

    I need your help.

    I got new iPhone 4S and i'm new to the iPhone.

    After i complete the full charge up to 100 %, then my battery go down 1 % almost every one hour (i will not be using the iPhone in this time... and no applications ON).

     

    Is it normal?

     

    Also, what is the normal / good battery performance for new iPhone 4S usually?

    how long it must stay if i'm using normal usage and few times checking email or facebook?

     

     

    thanks and regards

    observe ur new phone first..since it was new. try to observe it about a week or less.. even it is 100% battery and not using it.. it is still possible to drain 1%per hour, by the way try to off location services and limit ur notification if ur not going to used it. as of 3g usage, u have 6hrs normal usage when its on. see specs. battery is depend on how you used the phone. try draining it first up to the point its shutdown! then full charge it again then observe..

    Thanks DevilMark for your reply and help

     

    Actually my iphone is now more than a week. I did drain the battery till shutdown and then full charge it.

     

    It's draining almost 1 - 1.5 % per hour when am not using the iphone.

    For example: I removed the charger today @ 08:00 am and it was fully charged (100 %).

    i didn't open any application and i kept the phone without using it (only i had two calls each one for less than minute)...
    now it's 04:00 pm and the battery is now 90 % which means (10 % in 8 hours = more than 1 % per hour).

    i'm in the office and the wirless is on (so no 3G is been used).

    I did on the location services ONLY for the (Find My iPhone) application; and all remaining off.

     

    I limited my noticifications to the below only:

    Phone, Messages, Rimnders, Calendar, Skype, WhatsApp

     

    All other noticifications are off.

    Also since morning i didn't use or log to Skype or used the WhatsApp.

     

    Siri is OFF.

    Phone since morning is almost black screean, and i ensure that no App is opened in bacjgound (by making two clicks on the middle button and assuring that no anything open).

     

    Sorry for this long story.

     

    Do you think that the battery performance is normal like this or no?

     

    I just want to be sure that my battery life is normal / good taking into consideration that it's a new phone (8 days).

     

    thanks for the help

    do your phone heats up or something when using internet or apps?.. and what is ur normal hour usage and standby mode?.. u can see it in setting general then usage.. normally when ur light to moderate usage u can get 24hrs or 2days standby and 5-8hrs usage time(100% down to 1%). if ur phone usage and standby near the range that would be ok. but if ur usage time lower than 4hrs by light usage thats not normal.

    To rphunte42 and Chris CA,

     

    Any battery, regardless of it's type, has a max number of charge cycles. Every time the device is plugged in to charge, it is diminishing the life of the battery.

    Read a bit more about how batteries work befire jumping down my throat about it. I work in a PMU lab and our focus is on maximizing battery power.....but thanks for playing.

    Over 3 hours at 50% is normal. What more do you expect?  Apple says 6 hours of Internet use on their website on 3G and 9 hours on wifi but those numbers are only if you do just that. That doesn't take into account phone calls or texting or location services. If you want better I challenge you to find an android phone that does better. Quit whining because you don't get 24 hours usage off one charge.

     

    Considering I am inside the whole day on wi-fi, I would say that 6 hours is in fact not normal. If it was, do you think that there would be 806 pages in this topic thread? I think not. Look pal, we are all Apple fans here, but let's call it like it is; Apple has designed something with a serious flaw here. They have already acknowledged this fact. Why you have to be rude and arrogant in defending them when they won't even defend themselves is beyond me.

    Had you read my post prior to responding without thinking, you would have read that I had turned off all location services and was strictly using wi-fi.

    Also, where was it stated that I wanted 24 hours of use on a full charge?

    Thirdly, there are a number of Android phones that can last much longer. Nokia, Motorola and Samsung all make 1 to name a few....would you like a link to a site that can support this?

     

    Stop being such a fanboy, but more importantly, stop being rude and trying to make enemies in a place that is designed to support Apple consumers and their fans.

    Now we've had two poster, Daii and DevilMark, who sport the ~8 hours usage I'm aiming for. I noticed some other posters before when browsing through the thread... Evidence enough for me that it CAN be done.

     

    I wonder if it's only a software/settings/usage habit issue

    Most likely the major difference is in usage.

    Talk time is 8 hours and that means using only the phone app. That doesn't mean 8 hours including a bit of internet, a few emails, etc.

    Once you start mixing and matching usage, the numbers get tossed out the window.

     

    Here's the specs from the -> iPhone page

    Talk time: Up to 8 hours on 3G, up to 14 hours on 2G (GSM)

    Standby time: Up to 200 hours

    Internet use: Up to 6 hours on 3G, up to 9 hours on Wi-Fi

    Video playback: Up to 10 hours Audio playback: Up to 40 hours

     

    Go here to see how the phone was configured -> http://www.apple.com/iphone/battery.html

    Most everything is at default settings.

    Note that in actual use, all these things are in an OR relationship, rather than AND.  That is, the numbers given assume that a talk time test means none of the other services mentioned are actually actively doing something.  That is, if the talk test is active, no internet use is taking place, even though 3G cellular data is on, and no video playback is taking place at the same time.  Note that video playback test is NOT from internet data, but ONLY from memory.  Also note that anything that uses cellular data requires more battery power if you have a moderate, or poor signal strength.  While it is not stated, and not tested AFAIK, ATT 4G (HSPA+)  times aren't likely to be as good as 3G times.

    That is logical.  3G time is less than wi-fi time, so anything you backup to the cloud is going to take more battery power.  Frankly backing up to the cloud seems terribly inefficient.  The only thing I use the cloud for is 'find my iPhone', and PhotoStream.  And PhotoStream only works when a wi-fi connection is available, and the PhotoStream app is entered.  Uploading data is too slow compared with USB 2 either with 3G or even wi-fi, so I regard using it for iCloud or iTunes backups as pretty inefficient.
