So I have read all about the CPU slow down with later iOS versions when you have a low battery and tonight have witnessed this for myself. My battery was below 20% and the CPU was only at 1200 Mhz. After plugging it in, and at 27% charge the CPU speed went up to 1512 Mhz where it sat until the battery was at a charge of around 41% and the speed finally went back up to 1848 Mhz. So this is news to me, lol. Although I had read about it, this is the first time I have recorded it (CPU Dasher X) and I still have to say that whilst it certainly isn't ideal, in my real world usage I have not had reason to think I can notice the difference. After all, I am only using Safari, a hell of a lot of Facebook and then Twitteriffic, so nothing that requires maximum CPU speed. Anyone else think they can tell a difference in use?
