Recommendation for battery use app?

[x1sspic]

My battery life has suffered recently. I used to get a nearly flat line when in Doze, now it's a steeper slope. What are some recommendations for being able to narrow down what's actually eating the battery (rather than the generic "Android OS" shown in battery setting)? Thanks in advance

I would try a cache reset (or even better, a factory reset) and see if that helps (if you haven't already). Frankly it's quicker usually than chasing the purple unicorn of "which app is it."

I have reset cache, do that regularly. As to the factory reset, I would like to avoid that. The concern that I have with a factory reset is that without knowing what is adding to battery drain, that as I reinstall apps that I just reintroduce the same battery drain.

I would be interested in people's suggestions as well. I occasionally get major drain and it is usually attributed to Android OS or some other system function, but my suspicion is that it's really coming from another app. Usually I can figure it out based on any recent installs or usage, but it would be nice to have an app that digs a little deeper and figures it out for me!
