For the past two days, I've noticed that my usage time is identical to my standby time for my iPhone 7+. The battery seems to be going quickly throughout the day so it's got me thinking that something is constantly running on my phone somehow that's eating away the battery. I pulled it off the charger this morning around 9 AM at 100%. I've barely used my phone today - some texts, checked email, and social media. No more than an hour worth of usage tops. But the battery is already at 69% by 4 PM. Does that sound right? My phone says I've used it for over 6 hours so far today, with a matching standby time. This can't be right. I've restarted the phone twice and this issue still persists. Anyone know if this is a glitch with the phone, with iOS 10, or with something somehow running in the background 24/7? Solution: I removed all exchange accounts from my phone and charged it back to 100%. The usage time is now different from the standby time and my battery is not draining as quickly.
