Why does the screen brightness decreases when Xperia Z heats? - Xperia Z Q&A, Help & Troubleshooting

It has something to do with a security to not burn the components? Not heat up more than due?

[Q] Reduce AMOLED power consumption?

Is it possible to reduce power consumption of the display? I already set brightness to minimum. Power Profiler shows that the display is using about 75% of total power consumption when phone is idle with wlan on.
450mW Display
600mW Total
If it is possible to reduce display power to 300mW the battery should last 33% longer.
I see only a small difference with low brightness or full brightness. (450mw low, 600mW high). No difference if Screen is white or Black. Maybe a bug in Power Profiler?
Try to set a dark background. AMOLED display only consumes power on dots that really on.

Brightness values in sysmon.cfg ??

Guys, today i successfully got root and first of all slightly changed the values in sysmon.cfg. Changed maximum brightness level (255) from first value till next four values, so there`s first five values set on maximum brightness, 255. And then the brightness gradually goes lower and lower till minimum (100) value. I did the same thing on my previous phone, Xperia T, and had no issues with this. What do you think, everyting will be OK with Z ? I don`t play games so much , more often surfing, music, movies. But when the screen is changing brightnes this is so annoying, so i`ve changed this values, but a little bit worry, because the screen is bigger and quad-core processor, so what do you think ?
Well, i guess noone knows exactly answer on this question, and in the meantime i changed the values, and set first 10 values to maximum (255) brightness level, and have no issues with this. Instead i have maximum brightness level of the screen when surfing and listening the music, but in games the screen still makes darker, when the temperature of the phone becomes too high, and in this condition i think the screen is better to be a darker indeed, to not to let the phone become too hot and not to damage it. But in the normal state i think that the screen in maximum brightness won`t damage the device. I hope so

decrease brightness

hello. today I saw that after playing and the screen is blackened . I always bring the manual and the maximum brightness . happens you know ?
Maybe your low battery mode was on...
As far as the device gets warmer, the screen dims automatically to prevent overheating.

Need port tap to wake up feature on Z2 for Xperia TX

hi all
could someone make it. or tell me how to do. thanks
A tap to wake without designated low power core for standby screen detection means massive battery drain, because you will have at least one of the CPU cores turned on at all times, preventing deep sleep. Z2's Snapdragon 801 has that feature.
