    I have had the 4s for three weeks now and I always charged it at night. When I will unplug it at 100, I will sleep for 10 hours and when I wake up it will still be on a hundred , however last night I used it for a while. When I webb to sleep it was on 95% but when I woke up it was on 89! After 10 hrs standby

    Why is my battery suddenly dropping when it did not before?

    So why wasn't it dropping when I had it on 100 the first three weeks

    6% on standby seems a little steep. Maybe you had some apps that drain when left on in the background?

    As for why you'd never see it before, I think 100% charge is more like 95% or so.

    100% and 1% on my 4S last significantly longer regardless of calibration or what not. I notice similar behavior.

    What do you mean 100 is like 95?

    Your phone is just fine. Some fluctuation in readings is normal. It's an indicator, not a precise gauge.

    Just use it & enjoy it :)

    That where the software reads 100% fully charged, the battery's capacity is actually a little more.

    It helps make the device look a little better over the long run, and helps hide eventual battery degradation. (example - gas tank will read full, but there is still room to "top it off")

    LOL. That's exactly the first thing I thought.

    Yes, power is consumed on standby. The device doesn't switch to running on ether or magic or whatever.

    Nowhere near enough info in your OP to even begin. What changed? This is standard troubleshooting practice.

    Does your body use energy when it's sleeping? Why yes, yes it does.
