Does your Experia e1 dim screen before they turns it off?

[777m]

I noticed this after i charge phone, then unplug charger:


Screen first dim after 25 sec then after 5 sec turns it off (screen timeout is set to 30 sec).
Dim. screen is on some 20% lightnes, and i can't change that..
My phone earlier doesn't dim screen at all,  it  just turns off screen after 30 sec.


Is that normal behaviour for phone, or something is wrong?

Thank you for your answer..

Do you have stamina mode or things like task killers installed or enabled?

No,i was just now reflash firmware, just to be sure that this isn't related to some program.

Same happen again on clean install.. Screen first dim then turns off after 30sec.

Stamina is off, auto brightnes is off, power saving off.. 

I just need confirmation is this normal on experia e1?

Earlier my screen didn't dim at all.. Maybe i was have some app which is prevent screen to not dim, and this is normal behaviour?

If it's happening on a clean install and your screen isn't flickering when in use then it's normal - out of interest have you updated prior to noticing this
