iPhone battery draining fast

[Kahsau]

All of a sudden my battery has been draining fast, 1 month ago it lasted all day, now half a day and I didn't change any settings.... Any help?

As long as your pocket doesn't get above 96° (around there) your phone is good.

If your mobile phone battery loses its charge too quickly, it is probable that your pocket is too warm.

Really? I have never heard of that, before. is this confirmed?

thanks
