before tethering, do a fresh reboot... then go to settings>apps>running apps> and stop any unneeded or misbehaving apps before you tether... its good to keep running apps to a minimum anyway to keep ram freed up... at least in my mind... this should help a bit... :-)
It's absolutely common, expected to happen. Just as if you were downloading something via 3G. Even with the screen off, its still quite a load on the battery and processor.
I believe that even closing unnecessary apps wont do much in this circumstance. Tether is tether.... your connection is working constantly( upload download)
Yes..it's a common problem with this phone. I turn my data/ 3g connect off. I usually don't tether too long but mine has become hot this way. And DON'T CHARGE OFF THE COMPUTER. It will get hotter faster. Some newer PC's are low voltage use (made to be environment friendly) and won't cause it to heat up, or as fast. Older PC's or Gamers that require tons of power to run a big system will generate tons of heat themselves ,and will heat up a cell in no time. Moderation is the key!
i use pdanet via usb on my ov. gets warm at times but never hot. i use pdanet because the tethering option in iho is for all windows versions above xp and i use xp prinarily so the built in option isn't helpful to me
There is a solution for this, in fact overheat happens while tethering because The phone is doing extra work for tethering especially when the tethering speed is high . try to limit the tethering download speed and it will be fine . look for app : bandwidth ruler for android
