Voltage limit to leave Power Off 2.95 +/- 0.1 Off to On

Voltage limit to enter Power Off 2.5 +/- 0.1 On to Off

a. ADC settings in the SW might shutdown the phone above this value.

b. During fast charging of an empty battery, this voltage might exceed this value. Voltages between 4.20 and

4.60 might appear for a short while.
