Battery life shorter after recent update??

[B0WIE]

My 10's battery life was always exceptional. After Android N, it got even better, using only about 1% for nearly 2 hrs of screen-off idle.
However, in the last couple weeks I've noticed that it's about half of what it used to be. Whereas an hour of screen time used to average about 15% battery consumption, it's doing close to 30% now. Battery drains about 2 or 3% for every hour of idle. That's still not bad but the jump is noticeable enough that I came here to ask about it.

Anyone experiencing this? I haven't added any apps and I'm not seeing any rouge battery consumption in the use stats...

Have you already tried a cache partition wipe? https://support.t-mobile.com/docs/DOC-25804

Also, if you have an SD card inserted, try Unmounting it (in Settings>Storage​), remove it, and then reboot. A corrupt file on the card can cause battery drain.
