oh yes. i had to learn that the hard way.
but i am not sure whether it was gyrator, or some other odd reason.
the day before i took my phone partially charged, about 50%+/- and was using it a lot. youtube, gps tool was on for hours and hours clearing memoery, internet, making calls, and i still made it home with battery to spare.
yesterday, i made a few quick calls, lil bit of gyrator here and there, some internet, gps. bam, the battery was fried literally. it was hot and dead.
