<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">A couple of times I have listened to one of my favorite streaming radio programs on my N900. Each time I listened until the battery was used up (neither time did I start with a full charge), and I noticed that the N900 was rather warm. Now, I listen with the unit in my shirt pocket and with the ear plugs plugged in. My shirt pocket has other plastic cards in it. and a sweater over it, so the unit is not getting much air circulation.<br><br>So, I am wondering, am I exceeding the heat specs for the unit by doing this? Would I have a problem if I started with a fully charged battery, and ran for more than an hour or two? If I plugged in the power cable and had the N900 on a desk in front of me while I listened, should I expect the unit to be cooler over a long period of time?<br><br>TIA for your attention.<br></td></tr></table><br>
