The 1st-15 days, this phone has been great!!!! Unfortunately, I had my first issue today. I noticed my battery was draining more than usual this morning. When I looked at my "battery usage" I noticed the OS and Android system was extemely high. 60% to be exact. Typically the display is higher, so this is way out of the norm. I checked to see what was running, but nothing out of the norm...... I did a factory reset and will see what happens........this is so disappointing. Anyone else experiencing this????????
