I used to only worry about this issue with my Touch Pro 1(the worst) and Touch Pro 2 with the crazy power problems. I haven't had this issue come up yet. Mainly because I only use Wi-Fi right now and unfortunately Garmin or Tom Tom doesn't have a standalone GPS solution for me to really tax the phone like I used to.
On the TP2 when I was running Tom Tom, on a phone call, using a bluetooth headset and charging the phone all at the same time I'd get the blinking red light. I thought we were past these issues with the Arrive. Mine hasn't really gotten too hot. It is slid out a lot during use because of quick texts and e-mails while on the phone. Maybe this has helped me.
