Iphone 4S charging is acting weird after updating for the first time in a few months.
First off, I take great care with all of my electronics including my phone. I've kept my iphone in pristine condition but have neglected to update it's software since probably February or March. After updating it, I would plug it in to charge and after a moment it would begin giving me the tone that it had been plugged in and unplugged over and over. I've read up on this and have since stopped using any of my third party chargers.
The problem is now this: Each time I plug my phone in it will only charge around ~%20 of the total battery life (according to the % indicator) and not go any further. I have noticed that I can actually unplug and replug-in only to find it had only charged yet another ~%20 more after a while. I have cleaned its connectors, tried all of the tips and tricks I've found across the forum. It seems to me that it's something going awry with the software.
