Desire overheating

It sounds like you have a program running out of control.
If you press menu, Settings, About phone, Battery, Battery use
what has been using all the battery power?

Ok I factory reset my phone and lost all app temps have dropped by around 2 degrees but my mV are all over the place I have decided that I will trade my phone in again a black berry had enough of what was a awsome piece of kit turning into a useless tool that can't handle my demands

Well I went to town today and traded the phone in.and I'm now the owner of a blackberry storm 2 and the only thing I'm.missing is the amount if apps Android had otherwise its the same as ny HTC except the battery lasts 2x as long at max use

just got my Desire back from vodafone, new mainboard, i already tested in sunny Lisbon (27c) working in the sun, for navigation in the car with google maps navigation,  
the old one, in direct sun lite it would not stay on for 5m.
Now it is ok!
and since it is a new mainboard and IMEI, i have a renew 2 YEAR WARRANTY . thx voda... lol

but that's not all, they also changed my screen from a SLCD to a OMOLED
and i don't think that's ok!

when i delivered my desire to vodafone, they lent one other htc desire to me, it also was amoled, but it add much better viewing angle, and less tending to blue.

my new screen was a very poor viewing angle because the colors tend to much to the blue when i tilt the phone, it also is very bright, does not have as much definition as the SLCD, and i think the one voda lent to me ad also better definition,  but at least the black is really black and color very vivid!

do you think that what i have  seen, 3 different screen's in 1 week, and considering the characteristics of my new screen, are normal for amoled screen? ?

thx in advance (sorry for the inglish)
