economy mode

[Mantero]

It would be much better if in battery saving mode there was the option to program the phone to start saving mode at a certain time and turn off the economy at another time automatically. Example: option to program the phone to start saving at 11pm and stop at 9am

good idea

i think a black and white display mode should be there to prolong battery life and to minimize burden on eyes due to dazzle

For "black and white display" go to: Settings -> Accessibility -> Direct access , check only "On" and "Grayscale".
Now you can press 3 times Home button to make display "black and white"
