    O no, not another battery question. My apologies.

    I have a 4S and noticed recently that after about 5 hrs of light use, the battery is completely depleted. Pressing Home button does nothing. Never even get the "Less than 10% left" warning before it shuts off. Ten minutes on the charger and the screen comes back and battery shows ~ 55% charged.
    Obviously none of this makes any sense.
    Has anyone seen anything like this before?

    Given that the 4s is now 5 years old, I would recommend taking it to Apple and having the battery replaced.

    It makes great sense, sounds like your battery needs to be replaced.

    Funny you mention that. I replaced the battery a couple of months ago. Maybe a defective battery?

    That would be my first suspicion. I would take the device directly to Apple and have them take a look, better safe than sorry.

    Would be odd for a recently replaced battery, unless it's perhaps defective.

    What do you mean "resting"? Did you mean "resetting"?

    I did. It's a pretty simple job in a 4s.

    It could also mean the battery you used was not an OEM Apple battery and that could also be a problem.

    Could be the replacement battery was also second hand and had been used before.

    There are apps out there which show how many cycles your battery's been through, worth checking new ones when first installed to make sure you've not been sold a dud.

    From what I know only app which can show you battery cycles is CoconutBattery only for Mac. With iOS 10 introduction these info is no longer available on phone - no app can get this info.

    That's what I was thinking.

    Hopefully, with a 4S, the OP isn't running iOS 10.
