Very bright, large, shimmering object with propulsion

My 17-year old spotted a large, very bright object in the sky that ascended with a glimmering pale bluish-white light illumination propulsion. When he began to film the object is stopped ascending and remained idle in the sky for a couple minutes until it vanished. Two brand new iPhones phones were filming the object, one overheated and the other lost complete charge. Digitally documented through the night. The object reappeared briefly the next couple hours behind a nearby star. There was no noise generated. There was little movement by object once we identified it in the sky. The object was identified in protected FAA commercial airspace but did not see anything on the FAA data tracker. Oddly, we were the only two people to see object in our immediate area as it was still very light outside. This is the sending sighting in the same area in two years.
