 And even if it seems to help for a moment, it's not going to fix an overheating problem. What to do instead? Clean the device's vents. Dust and dirt build up inside over time, clogging up everything. Next, don't run too many programs at once. And if some snoop has put spyware on your device running in the background, it will also run hot. Finally, if you get a warning on your phone that it needs to cool down before you can use it, don't let that happen again.
