Difficult problems with battery

[wright02]

Well do you think is it really gonna help ? I just wonder cos i had this setting already set on 10 ;/ and i discovered another thing. When my mp3 is playing and nobody is touching it like on playlist, when screen is almost all the time turned off, my device dont have problems to play alot but when it comes to changing songs, turining volume higher and lower the battery runs off really quickly. Is it normal?
