I just got my P6P coming off LG and I'm tinkering around the OS. I tried using the Battery Share feature to try it out but it kept disabling itself whenever I turned it on. Is Battery Share disabled in Graphene?

Battery Share turns off when your phone:
Starts wireless charging, like when on a Pixel Stand.
Doesn’t notice that it’s charging another device after 30 seconds.
Knows the receiving device is fully charged.
Reaches a high temperature.
Senses power transmission isn’t going well due to poor placement, a thick case, or other issues.
Turns on Battery Saver.

Edit: I thought I was going crazy because I couldn't find that source. Not sure if this implementation of the Battery Share is significantly different from stock for this info to be included on the feature page.
