Why does my cellphone become hot while operating in 3G?

Answer 1

Hello and Hi.
3G uses more battery power so it gets heated up.
even when you talk more than hour it heats up.
To check your battery take the battery in your hand and see it holding i front of your eye if it is doom(the thickness) then better you change your battery for a new one.

Enjoy.
Have a great day.
God bless you.

Take it to the local store for repairs. It could be a defect. I do know of a phone that go so hot a ladies purse caught on fire.
Careful.
