    If anyone can help me here I'd appreciate it. When I unplug my iPhone 5c in the morning, the battery % is anywhere from 96-99%. And no apps are running in the background. The first couple weeks I had the phone this was not an issue. Anything to be worried about?

    It means you are likely over charging it. The battery is no longer is holding a full charge. Let it go all the way down then turn it off and do a full cycle charge.

    Hopefully that will reset the battery stats.

    After unplugging, I use my phone for 1/2 hour playing music and at the end of the 1/2 hour, it still shows 100% :eek: there must be something wrong with my phone too!

    Second thought, I'll live with it.

    I think some chargers tend to cut the charge off at around 95-98-odd percent, this helps preserve battery life. I had a charger that did this with my old Galaxy S3. As far as I'm aware it's not a fault with either the charger or the phone.

    But I charge my phone every night while I sleep. How can I prevent an over charge? Should I no longer do that?

    It's impossible to overcharge a battery in the iPhone. It'd explode if you did. The iPhone charger and the iPhone's charging circuitry won't permit it.

    That's what I figured. So I shouldn't worry about it?

    No.

    Your concern is only justified if you actually get substantially less battery life using the device. The percentages on the screen are often wonky and only fuel the fire for OCD compulsives.

    For all practical purposes, it really doesn't matter if your battery is 99% or 97% charged. Turn off the percentage display and move on with your life.

    Despite all of the above, many instruction manuals for cell phone warn against overcharging. This is not because a battery can be overcharged per se, but because extended periods of incoming electrical charging may destabilize some of the battery cells.

    In other words, once a battery reaches its full charge, it cannot be charged any further. At the same time, that electrical current that keeps coursing in has nowhere to go, creating a stressful electromagnetic environment and pushing the battery into more of an unknown realm. Depending on type, manufacturer and amount of time left plugged in, complications may or may not ensue.

    So, yeah technically it's not overcharged. However, it will likely shorten the batteries life.

    Nonsense. The charging circuitry is shut off when the battery is fully charged. While not using a lithium-ion battery will indeed reduce the battery's capacity, it's not because of a "stressful electromagnetic environment."

    In the event the charger or phone do not work as intended, it can cause disastrous effects. Like the poor person on here who had a 3 (I think) almost blow up on them.

    In the event your life doesn't go as expected, it can be disastrous.

    Having said that, I don't worry about try to keep my battery in "top condition". I keep it plugged into the charger when possible, run it down. I have a mophie case so a little wiggle room is possible.

    When the battery goes kaput I'll get a new one. If it blows up...apple has deep pockets. :D (sarcasm in case anybody missed it.)
