I prefer doing it through @flar2 's HBM app set to automatic when using his custom ElementalX kernel. They've made that kernel for each of the previous Pixels (and some other phones) so I expect once the source code drops they'll do so for the P6P as well.

It definitely made a difference in direct sunlight.
Oh wow. So the source code for pixel 6 hasn't dropped, yet?

    I've update High Brightness Mode to support Pixel 6/6Pro (version 5.03).

    The following command is how you can toggle HBM on our 6 Pro:

    Code:
    echo 1 > /sys/devices/platform/1c2c0000.drmdsim/1c2c0000.drmdsim.0/backlight/panel0-backlight/hbm_mode

    Replace the one with a zero to disable!

    I was playing around with this command a couple of days ago because I didn't feel that the maximum brightness was very good due to the Pixel 6 Pro using a Samsung s6e3hc3 display (cat /sys/class/backlight/panel0-backlight/device/panel_name), which is in fact the same display the Oppo Find X3 Pro uses & allegedly that goes upto 1300 nits.

    I found that:

    echo 1 >> /sys/class/backlight/panel0-backlight/hbm_mode

    and

    echo 2 >> /sys/class/backlight/panel0-backlight/hbm_mode

    Both work to give the Pixel 6 Pro to achive a little more brightness (& they stay on after switching the screen off) - obviously setting HBM to "1" provides a little more brightness than "0", and "2" provides even more brightness than "1".


    I used my ColourMunki Display to measure the brightness of the display multiple times & got the same results every time: these show that max brightness with HBM @ 0 is ~500 nits, HBM @ 1 is ~795 nits & HBM @ 2 provides 835 nits.

    I'm hoping someone can replicate these numbers or verify with another, more accurate device & hopefully (when ElementalX is released) we will be able to toggle both HBM modes via the HBM widget

    HBM = high brightness mode?

    Is it worth doing?

    Yeah I use Tasker to create QS toggle with that command
