    I'm shocked at how fast my new 5S seems to lose power. I thought battery life increased by 10%. Around 9pm last night it was at 40%. I checked at 2am and it was at 15%...by 6am it was at 6%. And all it did during those four hours was to sit untouched on my nightstand.

    This was on the original store charge. I will run it down to zero and give it a new charge today and hope it improves with some use.

    Might I suggest actually using it first before passing judgement?

    Did you not read my second paragraph??? How long do you recommend I defer any kind of observation of the speed at which it seems to drain, one week, two, a month or perhaps a year?

    You either have a defective phone or one heck of a lot of cr^p running in the background. My 64gb 5S battery life is better than my 5.

    If everyone had battery life like you claim it would be reported a million times here. Not happening.

    Fyi mine drops about 0.5% per hour while idle, but I disable a decent about of crap.

    Many iOS 7 features are battery hogs. After you do your full drain and recharge you might want to tweak the settings. Google iOS7 battery extend. There are several articles on which settings to change.

    It's capacity is 10% more, doesn't mean it'll last longer

    Thank you all for the advice. I did disable many of the energy hogs like dynamic wallpaper and parallax. I ran it down to zero and am now doing a full recharge on it. I will also disable other features as I can. I will post my results.

    It does actually. By definition.

    Actually walmartmartyr is correct. A 10% increase in battery capacity will last longer only if the device's battery drain is exactly the same...

    So if two devices have exactly same drain of say 1 watt per hour then yes the one with the 10% larger battery should last longer

    If the new device ( 5s) uses a bit more power and this is probably very true as the 5s has a faster processor and true multitasking; so say it uses 1.2 watts per hour.. Then the 10% increase does not always mean the device will last longer...

    I agree with you. But a battery that has 10% more capacity than another battery, will last longer. By definition. Without context, just saying 10% bigger capacity won't last longer is misleading.

    1. You're playing with it a hell of a lot more.

    2. It's a new battery cycle it at least 5 times before you comment on battery life.

    Yes, I did read it...

    The point is, you should be waiting to actually get a proper charge and play around with it before posting about the battery right out of the box.

    True. You are right!

    My battery has been similar in drain to ios6 on my 5. You'll need to check the apps running over night. A lot of emails or other notifications that wake the phones display will drain the battery at night.

    It does not. While iPhone 5S has a larger battery than iPhone 5, it uses an entirely different processor along with other different internals. There are no reliable benchmarks available that suggest the A7 along with other chips found in iPhone 5S is as energy efficient as iPhone 5's overall internal setup.
    Saying 10% more battery equals more battery life without data is quite silly.

    No it don't. If your battery is 10% larger but it's running something twice as powerful, then battery life would b worse
