metal cover on original htc batterie

[sackbauer]

on the back of the original htc batterie pack there is this metal cover which i have seen on almost every htc device.

is this a sort of radiation- or heatshield between the batterie and the phone ?
replacement batterie packs do not have this metal cover ?!

no one knows the use of this metal cover on the back of the htc batterie pack ?
maybe it is of no use ... but then also i want to know about it ;-)

i think it is because of the battery heat. isn't your touch dual not getting pretty hot while surfing or playing?

[sackbauer]

yeah batterie is getting hot even when i phone on 3g with bt headset ....

For me, it isn't the battery which is gettin hot on 3G.
It is the rear side at the bottom (under the battery).

I think the 3G parts (chip? antenna?) themselves should be blamed for that. :p

[sackbauer]

you're right , i just checked ... and it is not the battery which is getting hot - it is below the battery ... so it might be the 3g things which makes the device burn.

in anyway - just wanted to know if it is any disadvantage using a replacement batterie pack instead of the original from htc regarding the metal cover .
