yeah...definitely something isn't right...
I think referencing the search concerning bme, battery consumption, hot battery, fast draining battery, that kind of thing...
will likely show up threads where these issues are prevalent.
There may be remedies, fixes and suggested courses of action to take to troubleshoot exactly where the issue may be springing from, and nip it in the bud.
Also, said threads will definitely have the folks assisting, who will be obvious as to their understanding of the issue.
It being a forte of theirs.
So failing finding an in-your-face obvious answer or set of instructions to follow...
you will definitely know exactly who the battery wizards are and then pm them directly and get their aid...

Whatever you do ..
Definitely if you continue with this...
it would be good to have a running dialogue on this thread of what is suggested you do, how it went, and the results...
It would definitely help any who come after you ...
looking for an answer to the same problem .
