rejaul2005, Have you got the sleep setting set on your player so the LCD turns off when not in use to conserve power. To do this you need to go to Settings>LCD set>Darkle or Black and set the slider to 0 - 30 seconds then press play to accept the setting.
The other thing I have heard but as yet can not verify as I just started testing today is adjusting the battery type in your firmware.
In your firmware there are 3 battery type options
1) 1.5v Alkaline battery
2)1.2v NiH battery
3)3.7v Li-Polymer battery
The claim is if your firmware is set to 3.7v Li-polymer if you change it to 1.5v Alkaline battery it will increase your play time by a couple of hours.
To find out your setting you need to extract your firmware using s1fwx and repair it. Then running the list.bat will open a command window and list all the attributes and files in your dump.bin. Near the top you will find your battery information. If it is at the 3.7v setting you can change it with Firmware Modifier save the setting then reload the firmware back to your player.
s1fwx can be downloaded from HERE
There is a guide to using it HERE
Firmware Modifyer HERE
When I finish testing I will let you know.

Guest, Yep tried it on 3 different players, did not seem to make any difference.

XTransbus, I have replaced a 230mAh Lithium Polymer battery that gave me about 7 Hours continuous music play with a 400mAh Lithium Polymer battery which extended the play time to 11 hours continuous music play. I had to remove the speaker to allow for the slightly larger battery but never used it anyway.

Where did you get the 400mhA battery???

Guest, From a model shop. Lithium Polymer batteries are good for remote controlled planes etc because of their power to weight ratio.

how much do these batteries usually cost? if they cost too much, i rather get a new player lol.

eternboy, I paid $22.00 NZD and a 530mAh was $29.95 NZD but it was a fraction to big.
