    I was talking with a woman at work that has an s4 and she was told to immediately unplug the phone or else this will shorten battery life. Any truth to this?

    I know that was true for older batteries.. but I think it stops charging now when it's fully charged. But I still take it off when it's done. I am sacred to take any chances.. lol

    For older batteries this was indeed true.

    For newer batteries it is no longer a requirement. The chargers and batteries on the new crop of phones will shut off and go into a trickle charge state (if needed) when they reach full capacity.

    The only things you need to avoid doing too frequently are discharging the battery completely and letting it get too hot as these will both cause the charge capacity to deteriorate slightly over time.

    I thought as much, I think its just a case of old habits die hard. She swears that shes losing battery life from having done that I just think as batteries get older they dont work as well.

    I was told the same by Samsung support when I contacted them about my poor battery life. I told them that I usually plug mine up when I go to bed and unplug in the morning when I awake. I informed them how inconvenient it would be to awake after a couple of hours just to unplug the phone. They replied sorry for any inconvenience. Not much help.

    I bet you that as the woman has it instilled in her that you need to unplug the phone as soon as it gets to 100%, she is perceiving a shorter battery life if and when the phone isn't unplugged immediately upon 100%. I reckon that the degradation in battery life is far, far less than she perceives. It's the age old 'truth vs perception' argument that basically says that in subjective situations, your mind will perceive the truth to be whatever fits in with your world view. In her world view, the battery is lasting less and less time due to the fact that it stays on the charger after 100%. Only accurate measurements will turn this from subjective to objective truth.

    It's human nature though, so i'm not having a dig at her. :p

    This whole "when to plug-in/plug-out" nonsense usually does not apply most all modern smartphones with Li-Ion batteries.

    Here's a quote that's pretty accurate:

    You shouldn't let the battery run down?

    Technically yes, but you shouldn't worry about it.

    Yes but this is only an advisory. Don't let it sweat you if the battery does run out completely on occasion; it's not going to b0rk your battery unless you constantly do it.
