I am a Sprint HTC One user, which has the constant power saving option in the notification shade. It is a rarely used option for me, but I have used it before and have been happy with the results.
But what is the ridiculous motive for Verizon to remove such an option? It makes absolutely no sense. Even if it was never used by any Verizon subscriber with a One, what's the point in removing such a small and pretty much insignificant option? What did that gain Verizon except for threads like these and people standing around scratching their heads asking the same questions I just asked lol....
