I have no idea what was in the update and I have no idea if this is just coincidence. As I've done every night the last week or so, last night I went to bed with the phone charged to 100 percent and Airplane Mode activated. This has usually resulted in anywhere from a 3 to 6 percent loss of battery overnight. But last night? Nothing. Awoke this morning, nearly eight hours later, and the Edge Plus was still at 100 percent. First time ever. The only thing that changed was this new software update. Again, could simply be coincidence.
