Nokia 5610 Express Music
Problem with battery backup

Hi,

I have recently bought a Nokia 5610 Express Music mobile phone.

For your information, I had been using the nokia sets from last 5 years.

This is the first time that I am facing this issue.

Isssue:- This phone is having a very low battery back up. Even if I am not listening any music and also not making any calls then also the battery hardly works for 1.5 days (approx.).

And if I listen some music on it, then it hardly works for 1 to 2 hours.

As compare to my past experience with Nokia sets, this phone is not having that much battery back up.

My question is, with such a low battery back up what is the need of putting this set in the market with the name as "Express Music".

Please look into this issue, or else give me some suggestion.
