Why is the bottom left corner so warm? (wifi issue?)
I've noticed the bottom left corner (on the back) to be slightly warm under moderate usage, but recently it seems to be warmer than usual. Wifi strength is really low (1 bar) even when right beside wifi router. I don't have any wifi security enabled on the router. I restored through iTunes and still same problem. Nothing internal was changed between when it was fine and now nor was anything changed on the wifi router. Everything else works without issue.
Parts I've replaced a few months ago: battery, back cover, digitizer, lcd, headphone jack.
Is this a good question?
