This is where I would love my old Samsung's "ultra power saving" mode. Nothing but calls and texting on a black and white screen. Almost a week of battery life.

What phone is that?

My S7 had it, and so does my S8. Very cool feature that I haven't seen in other phones.

My S7 has that. In my area (with good coverage) it lasts 9 days! in standby.
