[drimchaser]

 i am encountering a problem with my sony xperia sp unit.. technicians told me that it was about the battery of the unit. will someone help me to resolve this problem? it is hard to turn on, when the phone is on, it wil shut down automatically and the unit gets hot.. if i need to replace the battery, where is it available and how much? thank you!

I suggest you should go to your local Sony center service. I had similar problem and they fixed it under warranty. They changed the battery as well as some other hardware components.
