The battery meter is an estimate, not the real thing. Hence you might have not lost that 1%... it could be 0 or more. Guage on usage or idle data.
The battery statistics displays both on screen usage times and background activity times. Tap on each item to switch between usage data breakdown. --- Post Merged, Oct 25, 2016 --- And btw. Do you use FB a lot?
Good you found the culprit. I turn off ALL background activity. FB on Droid would drain an S7 Edge about 10% per hour in the background. Good you don't use it. It's a facade of stupidity. --- Post Merged, Oct 25, 2016 --- Oh. War Eagle?
I went to bed last night at 10:30 pm with phone on 100%. Got up with it on 98% at 5:30AM. Very happy with it's overnight performance, which included roughly 15 facebook and 12 email notifications and about 15 tweets.
Yes last night it was 10:30 bed and 5:30 up and still on 100%, but very little activity, with just a few emails and facebook notifications. I have never been able to get that with any iPhone in the past, and it reminds me of the 6-7 day battery life of the old Nokia bricks I had almost 20 years ago
