After only about 6 months the F-S1 battery in my 9800 is loosing its charge very quickly and I bought another battery. Whilst this seems to have solved the problem another has started. The new battery was supplied with a cradle and instructions for setting up the new battery. One end you place the old battery and the other end the new battery and you wait for the red light to go out.
This is fine until you need to reboot the phone or take the battery out and most times re inserting the battery brings an image of a white battery on the screen with a red X over it. The only way to get the phone working again is to go through the pairing process with the old battery and cradle. Any help would be appreciated. Before getting the replacement battery this was not an issue
