Since the system update from 30 October my XCover Pro has excessive battery drain. The top ranking app in the battery usage listing is the CameraLightSensor system app, responsible for using the front camera as a light sensor for the Adaptive Brightness functionality. If I let it do its thing it will consume up to 20% of the power per day, even when the phone sees little active use.
I have followed the usual recommendations for battery drain, to no avail. There are clear indications this is a bug introduced by the update:
While I can live with the Tasker "solution," this looks like a clear bug to me and there may be more wrong with this (5%/day still seems a bit excessive for what this does, so I suspect the CameraLightSensor is in some kind of "overdrive" whenever it is on). Also, Tasker is a paid app and users should not be expected to buy this as a workaround to manufacturer bugs.
I have sent error reports to Samsung support using the Members app, but never received any response.
As Helge Nicholson stated above, I same the same issue with adaptive brightness since the last update, when Bixby was replaced with Free. Does anybody knows of a solution to this problem?
Over the months I have been getting this intermittently. The monthly software update would fix this, but it has reoccurred later. The most recent one happened for me after a Zoom session on battery, which makes me suspect that maybe some apps can mess up something in the power control, and the software update just resets things? Eh, too little data to tell.
Either way, I have not been too happy with the effectiveness of the adaptive brightness feature, regardless of the power consumption. I know it is supposed to learn, but a year in I still found myself turning down the brightness when it is dark, or worse, struggling to turn it up when out in the sun. For the past week I have turned the adaptive brightness off and instead used a button remapper app to make the combination xcover-button + volume-buttons control the brightness. That way I can quickly adjust the brightness, even out in the sun when I cannot see the screen - and it will not pick weird brightness levels on its own, and no power issues. Should have done this months ago.
Thanks for your advice. I downloaded a button-mapper and it works very well. Just two key combinations and it's all in my own hands now. Never a too bright screen anymore.
