I read quite a bit on my iPad, which is also synced with a Kindle. As I read, I usually try to stop at the end of a chapter, instead of in the middle. To do that I have a tendency to rely on the clock in the lower left corner of my screen that shows approximately how long is left in each chapter. All of a sudden that clock is extremely in accurate. The Kindle, which does seem accurate is about 2 1/2 times as long as the iPad. I have timed a few chapters. What the Kindle says will take about 13 minutes is usually about 5 minutes on the iPad. The Kindle is correct. This has only just started happening. I tried turning the iPad on and off but it made no difference. As I said, this ain't exactly crucial, just annoying. Any suggestions?
