The saga continues for me. After running great for nearly a day after the Exchange fix I mentioned earlier, it started acting up again. It is still Exchange related. Exchange started sending me calendar notifications over and over for the same meeting (the one I was attending at the time). My CPU usage was up to 25%, even though I wasn't doing anything. It was Exchange churning away in the background trying to desparately send me notifications for this meeting.
I turned off push notifications for Exchange, and switched to fetch every 15 minutes. That seemed to calm it down. I think it is still burning a bit more power than normal. Looks like I will need to belly up to the Genious Bar again..
Some kind of incompatibility between Exchange and ios 6.1, at least the way I have my phone configured. Strange that my buddy at work is having no problems at all, and he is connected to Exchange as well. I will have to compare settings with him. He also has an iphone5, same as me. In fact we bought them within days of each other.
Anyway, this is unacceptable. Needs to be fixed. I'll update the thread if there is a new development, but it may be a couple days before I take it back. I may even consider doing one of the more exotic fixes, although it seems like a witchcraft procedure. What am I supposed to chant while doing that? :-)
No offense meant, just a joke. It might be good to explain what you think those particular set of steps accomplish, though. The reasoning behind it.
