When I say iOS 8 is very buggy, it's not a lie. So many things will suddenly drain the battery unexpectedly.
Example 1: I used the camera app to take TWO pictures. I pressed the home button and turned off phone. Five minutes later I felt the phone getting real hot in my pocket, I didn't understand at first. Then I checked the battery and boom, 20% of it was utilized by the camera within the 5-10 mins.
Example 2: yesterday when I was posting the very post on this thread, again, I put my phone down on the table. 10 mins later when I picked it up, it was very hot. Checked battery tab and guess what: safari used 17% in just 10 freaking minutes just to post a message.
Surely these problems are definite bugs with this crappy iOS 8 which in my opinion is the worst OS apple ever released. I've had so many apps crash as well. Many of them are apps that are preloaded onto the phone - APPLE'S OWN APPS! 8.0.2 or whatever didn't fix much of that. If this is the path apple is headed under its new leader, it doesn't bode well for the future of the brand. Now I can't tell android trolls that my OS is very stable and my apps don't crash cause that's just not true any more.
