Just because it’s interesting to compare: it was worse for me. My 6 Plus (three years old) ran at 600Mhz most of the time according to CPU DasherX, fully charged or not. Normal is 1400Mhz. I replaced the battery this morning and it’s back to the normal level and is quite noticeable in real-world usage doing practically anything. (It wouldn’t surprise me if the GPU or something else in the rendering pipeline was even more affected than the CPU. There were previously long delays in things that just seem to be screen rendering. Those delays aren’t just faster now, but are completely gone.)
