Does anyone ever notice their display very slightly... but noticeably... suddenly dim when on battery and viewing content? I have "auto" brightness turned off. It happens when on battery but in theory it should not dim on its own. Adaptive display is also turned on but again this should not affect screen brightness. I believe it happens in Chrome but possibly in other apps as well. It's pretty random. It happened on my Note 5 as well. I guess it's normal but I'd love to understand why it's happening.
