Hello all! Quick question: "My 700wx will shut the phone off and leave it off even after I deliberately power it on. However, the only time it does this is when the phone powers down when I let the battery drain to zero. The phone won't even stay on when I plug it in however after about 20 minutes if I return and power the phone back on it stays on. Question: 'Is there a minimum power level needed to keep the phone application on and is the phone the first thing to be shut off if the battery is completely drained?' Thanks!"
