I'm running IOS 10 on a iPhone 6 and since the update my battery consumption seems crazy. Before the update I usually had to charge my phone every night but since the update it's not even lasting the day. Yesterday my phone was only unplugged from roughly 11 AM to 5:30 PM. The only thing I had had open all day was the native messaging app which according to the usage in settings had used 77 % of my battery.
Is anyone else experiencing this? I was hoping to keep my iPhone another year but if the new IOS is draining battery quite like this I may have to upgrade.
