Are you powering it off before you plug it in? Because all i-devices are made to start back up when plugged into power.

Do a thorough visual inspection, preferably with magnification, of the area surrounding the battery connector. There are several tiny SMD components just above the connector. Of particular importance are the ones highlighted in blue below. If any are missing (which can happen when you pry the connector off), then the battery state does not get communicated to the CPU and this can also cause charging issues and fluctuating readings.
