My lightening connector does not snap in like it used to. I get a "USB device drawing too much power" error message and the iPhone doesn't charge. Is this a bad cable or bad connector in the iPhone? I'll pick up a new cord tomorrow to see whethr that solves the problem.

Hello there, DSteinhorn.
The following Knowledge Base article gives some good pointers with issues charging iPhone, if getting the new cable doesn't resolve your issue.:

Specifically:
Charging the battery
To charge the battery, choose one of the options below:
- For the quickest charge, connect the device to a power outlet using the USB cable that came with the device and an Apple USB power adapter.
- Connect the device directly to a USB port on your computer (not an external keyboard) using the USB cable that came with the device. Your computer must be turned on and not in sleep or standby mode; otherwise, the battery may drain instead of charge.
- For the quickest charge while connected to a computer, remove all USB devices except the keyboard and mouse.
- If using a portable computer, make sure it is plugged in to power and that the display (or lid) is open. If the display is closed, the computer may go into standby, sleep, or hibernation mode and the device may not charge.
- Connect the device to an externally-powered USB hub.
For the quickest charge, disconnect other USB devices.
If you charge the battery while syncing or using the device, it might take longer to charge.
Additionally if you're working with a Mac, you might try the following:.

I took the iPhone to the Apple store and they discovered pocket lint in the lightening connector jack that prevented the miniplug from seating fully. The charging cord was also thought to be faulty and was replaced. So, beyond the physical problem of lint that was easily cleaned out, a faulty cord with an internal short could have caused the error message. It is working fine now with a new cord and cleaned out chargning jack.
