The battery life remaining is estimated from the stock battery capacity and known runtime, its not actually measured from the battery you have installed. If you change the battery, you'd have to change the battery capacity listed before the estimated runtime will be different.

Ok thankyou, any idea how I do that? thanks.

Edit the defines here to your new mAh settings, and then compile a fresh build:

This could work--I've been meaning to fiddle with this little player, and I now have an excuse. Cheers! :)
kae64:
same problem. Who will help to make changes to the firmware file. I am far from programming. so I can flash your player sansa clip+.
I bought a 3.7v 1050mAh lithium polymer battery with inbuilt protection circuit to replace the standard 290 mah one, I didnt use the orginals battery circuit that stops overcharging as it has its own so ive just connected red and black to the mainboard from the battery. once fully charged to 100% it shows 15hrs left why?
#define BATTERY_CAPACITY_DEFAULT 290 /* default battery capacity */
#define BATTERY_CAPACITY_MIN 290 /* min. capacity selectable */
#define BATTERY_CAPACITY_MAX 290 /* max. capacity selectable */
#define BATTERY_CAPACITY_INC 0 /* capacity increment */
#define BATTERY_TYPES_COUNT 1 /* only one type */
and the need to
#define BATTERY_CAPACITY_DEFAULT 1050 /* default battery capacity */
#define BATTERY_CAPACITY_MIN 1050 /* min. capacity selectable */
#define BATTERY_CAPACITY_MAX 1050 /* max. capacity selectable */
#define BATTERY_CAPACITY_INC 0 /* capacity increment */
#define BATTERY_TYPES_COUNT 1 /* only one type */

I don't understand what you are asking.
