Fuze v2 displaying improper battery percentage
« on: August 31, 2010, 11:23:18 AM »
On my Fuzev2, the battery percentage will change when I insert a USB cable to charge it. For example, it would say 28% with out the cable plugged in, but then would drop down to 15% when I plugged in the cable to charge it. Any reason on why that would be happening?

Code says this:

/* ADC_CHG_IN seems to represent battery voltage better than ADC_BVDD during
 * charging (ADC_BVDD is way too high) and appears the same in normal use.
 * Note that when charging some models do not give an accurate reading but jump
 * between 2 values. */
