Like many PRIV users, battery life wasn't great for me, particularly over the past year or so.
Typically, I'd be losing 25% per hour of screen time, even on battery saver, and even with the screen at 1080p or 720p (yes, I went that low). Even with AccuBattery I couldn't find the culprit.
Then, I removed the Outlook app and added the work account in Hub. Voila, instead of losing 25% per hour, I'm losing around 17%.
I had no idea an email app could drain so much battery, particularly in terms of SoT. Outlook never showed up in my battery consumption list.
So, if you use Outlook and are experiencing poor battery life, get your email on Hub (or another mail app) and get rid of the Microsoft bloatware.
