no list of App Usage in the Battery Settings
I've just had a new battery installed in my iPhone 6 w/iOS 10.3.1. I also reset all settings. My old battery was so screwed up I really couldn't track longevity. Now, I notice that battery percentage drops without doing much of anything. And, there's no list of App Usage in the Battery Settings. Now I wished I didn't update to 10.3.1
Is there a way to restore to an older iOS from my iMac backups? Should I just wait until Apple fixes it (Ha)?
Or should I erase all content and setting and start from scratch? And, is this a painstaking process?
Thanks in advance for any tips
