Autobrightness vs manual brightness? Traditionally I use manual brightness around 15-25% but its really hard to see in daylight & it's a bit awkward to manually increase it quickly. Wondering on peoples experiences regarding response time of sensor & battery effect of autobrightness. Technically should use more due to sensor polling but is the result negligible?
Curious on people's experiences.

You can measure the current power usage using csd, and see what effect the brightness has. Also, you can tweak the auto-brightness to your heart's content. Personally I don't bother too much, and have the slider half way, so the display is just at its dimmest in the dark, but has enough brightness to read in every other situation. Other factors tend to have a much bigger impact on battery life, with my usage pattern.

I have my display's brightness correcting automatically, with the lowest default setting.
Drain on battery due to auto-brightness is completely negligible imo, as you would use by orders of magnitude more energy if always switching brightness setting manually. Think of just wanting to look at events screen in broad daylight which only takes 2s usually, you would need about felt 2min to find the brightness control, if ever. ;)
If you find that auto-brightness' response to surrounding light is too quick/slow you can always change settings by using mcetool as discribed here.

For me even with 100% brightness content on the screen is hardly visible in direct sun light though I think it is because of the quite crappy highly reflective frontal glass protecting the screen not the lcd itself. I have autobrightness turned on all the time but since some update (uitukka iirc) it does work...but kind of slow. Autobrightness correction since then seems to hardly ever change in direct sunlight or with some delay after tilting phone in some axis. For me both auto and manual brigthness control could be done better. Minimal manualy set screen brightness is still quite bright in dark, and then in direct sunlight even with autobrightness on the screen looks like it's not even turned on. Then manualy set to maxmimum brightness, content on screen is still barely visible in sunny day and additionally blinding in dark places, cause minimum brightness is moved further in scale. In terms of visibilty in direct sunlight conditions, with current hardware limitations I dont think there is much we or Jolla can do, but the autobrightness worked for me better at one time (I remember not having those problems with not adjusting brightness on sunny days last summer) and first step on briggtness scale would be much darker.
