I have started to notice some strange behavior of my Evo 3 times over the last 4 days. Everything will be running fine until I hit a point where my CPU appears to spike to around 40% and plateau there, but ONLY while the screen is off. As soon as I turn the screen back on CPU usage drops back to < 5%. Rebooting seems to fix the issue, but now that it has happened 3 times since sunday I'm started to get concerned. I've tracked down plenty of rogue apps in android using systemPanel and spare parts, but I am having no luck with this one... I'm currently not rebooting so I can troubleshoot the issue... any suggestions?
