As of late I've noticed my iPhone 7 Plus feels a bit slower right around sunset. This can especially be noticed in Google Maps when scrolling around. On a hunch I decided to turn Night Shift off and back on, forcing it to turn on fully immediately, and the performance was back to normal. So it seems that during that gradual change from day to night mode, there is a graphics performance drop. Has anyone else noticed this? Is it a known bug?
