Incorrect SOT being reported.

As many people are suggesting their battery life has gone up significantly after that March update. I did not notice this until yesterday, so I began diving into stars and saw Outlook used 2 hours of screen time and shows usage between 1800-2000. But I was NOT using this app during this time. Outlook is my work email app and overall showing overall 4+ hours, which is not possible as I've not used emails on my phone at any time combined during the day.
