Sorry if this has been mentioned before
my cable internet was down yesterday, so i grabbed my TP and tethered for a good hour then the battery was dead..
so i pluged the TP in the bedroom and felt like it was crazy hot, i fired up WMWIFIROUTER and it worked but then it would stop charging and die again
so i unplugged the battery from the phone placed everything in one of my A/C vents, it cooled down in 2 mins plugged it and it started to charge..
but heat came back very fast, so i stuck the phone with the keyboard open and without a back cover back in the A/C's Vent while its charging, THATS IT
i tethered the hole day on it with out problems
today i tried the same thing with a mini fan that i had blow closely on the open tp and still works
so heat is the TP's enemy
