I have a Xperia Z5 E6603 usa version. Running build number 32.0.A.6.209.
I am finding that my when low battery mode is turned on and set in the activate at 100% battery positition, with the brightness adjustment set to zero the screen does not dim significantly or at all for that matter... almost as if the brightness did not override the Adaptive brightness setting. When I turn adaptive brightness off the screen correctly uses the zero brightness level.
Basically, when low power mode is engaged and set-up to automatically lower the screen brightness, it appears as it is not overriding the adaptive brightness setting.
I'm hoping you can understand this as it may be a little difficult to explain in a message. If there are any questions feel free to clarify.
