1. Open it up and read the capacity of the battery --- it might be low, or you might just have a bad one.

2. Use s1res v4.1. It should work on 9.1.x firmware.

the battery have 3.7v 380 mah

Have you also tried charging it by plugging it into the wall instead?

I wonder if it's a problem with the USB cable or USB connection on your player and it's not charging it properly.

There's no way your MP4 player is drawing 380ma, which it would have to for a full 380mAh battery to last only an hour, unless the display backlight is taking a huge amount (the controller draws around 25-30mA, i.e. a 10-hour runtime on it alone). Try setting the display to turn off with inactivity and see what times you get.
