Top Performance & UI Tweaks S25 Ultra
Just realized that the Galaxy S25 Ultra has the default Window, Transition, and Animator scales settings very nice and smooth...but perhaps just a tad too slow. So I went into the developer options and changed all three from 1x to 0.5x to make opening apps and switching menus feel a little faster and snappier.
That's the only thing I did and I'm not sure but the battery life seem to have increased by 3 - 6 hous more or less. The phone is also snappier now!
