BB Bold 9000 :: Call Fails And Severe Overheating

Had the Bold for just over a year, using Telstra in Australia and OS 4.6.0.144. No Facebook, have googlemaps but I exit whenever I use and have removed most apps.

Three times now the phone for no reason has got that hot that even in a holster on my belt, I felt the heat. The unit get's that hot that it drains the entire battery life in approx 5 min. I remove the battery, let it cool completely and then replace. Telstra don't know what the issue is and as it hasn't happened when I take it back, they will not look at it. Using the THB full car kit, the unit generates a lot of heat slow charging in the car kit cradle and on a heavy day I will get 3-4 hours use before flat, or I have to turn it off and let it cool down.

I have to soft reboot the unit evry 2nd day to stop the black wheel of death and the amount of Call Failed has increased to an embarrassing level. I have reported all these to Telstra and they are investigating.

I have since spoken to another user on Telstra with a Bold and upon describing my problems, he recounted a similar problem with his unit. His Telstra rep informed him that there was a problem batch of Bold's in Australia 12-18 months ago that had a known problem. They replaced his free of charge and he has had no such issues since and a massive increase in battery life. I recounted this our corporate Telstra rep to no avail.

We have 17 Bold's in the fleet, of which 11 came at the same time. Of these 11, 7 have the problem as described as above. Is this a common problem and how do I get Telstra to address ?
