I have been facing a weird kind of behaviour with my iPhone 4 (almost 2 years old). I had updated the iOS 6.1.3 a month ago.

Occasionally the battery percentage suddenly drops . Like just a while ago, it suddently drops from 24% to 15%. PLS note there is no app running in background.

I thought that may be something would be running. To confirm this, I looked at the usage but the usage doesnt show any such sign.

What i observed is that this happens only when battery falls below 30%.

Can anyone tell me whats this all about. Do i need to re-calibrate my battery?
