my iphone 4 is overheating while charging.. very very hot with slow charging
also rapid drainage in battery 10-15 % each 5 minutes...
i think the over heated part is the PMU Power Management Unit..
some says it's a software problem
others say it's PMU itself
others say ther are a short on the logic board

what u think?

I think you should restore to at least verify it is not a software problem. NOT FROM ANY TYPE OF BACK WHATSOEVER. Setup as new

And if this carried on contact your Apple store for the unit to be checked over.

Whenever I had overheating problems i made sure to do a full cycle charge by charging to 100% with an ice pack under my iPhone, with a cloth between them, to keep my battery cool, then letting it drain to 5-10%, then let charge, and keep charging at least 2 hours after phone shows it is fully charged.

That usually did it. If it did not, I restored, and setup as new iPhone.
