Default extreme power saver mode not wrking on some sense 6 roms

just want to inform everyone that this mode is not working on 1.54 roms and 6.06 roms

the only version this works is on 5.11 roms

thee xtremem power saver mode actually turns off all running apps and data conection and then display a notofication
usually when u exit this mode there will a lag when the phone shows the home screen.

in 1.54 and 6.06 roms there is no lag , so this show that this mode is not working as intended .

is there any way to make it work on all roms by editing some config files in the system ?

if so what are the exact steps to do thanks
