Help Extended battery heat issue

[lime324]

Hi all,

I just bought this extended battery couple days ago, it's for GSM version 2000mAh, and after I used it for a while I noticed that it gets hotter than my standard battery, is this normal?

last night it was up to 46C

I also face similar issue and i submitted my phone to Sony service center.

Did you use extended battery? and what did Samsung tech says? is it battery defect?
(I assume you want to write Samsung instead of Sony)
