By the way, guys, I tried charging my T68 to max and draining it all the way. It charged to 99% fairly quickly, but then took 10 hours to fully charge. When batteries approach full they begin to charge more slowly, which relieves wear and tear on the anode. At max charge, anodes decay more rapidly and suffer from higher temperatures. Higher temps accelerate entropy.

That suggests there's some kind of sensor issue. The battery itself contains some electronic overhead (as someone else pointed out). Batteries also don't output the same consistent amount of power as they hover near failure. Undersupplying power to an electronic device will cause it to fail. The battery itself could be causing the issue. Firmware might not be able to correct that issue.

Calibrating the battery will help offset this issue, but the looping should continue as the battery runs out of juice.

For those who wanted to drain their device down, I normally would suggest putting it into recovery mode -- I just learned that the Onyx's recovery mode has an auto-shutdown feature in it. If you leave it in recovery mode, it will boot into the operating system. Unfortunately, I don't see any good method of draining it down, other than the hard way.
I was curious to see if my Lynx would be affected by the reboot loop issue, so I didn't charge it at 50% (which is what I usually do with all of my readers) I let it go until I got a message that it needed to be charged (8% battery left) and I didn't experience any reboots.
