If the Nokia device does not display the battery charging icon when using the CA-101 connectivity cable to charge does not mean that the phone and/or battery is broken, but is caused by the way USB charging works. For optimization purposes, the phone prioritizes charging the battery over activating the display for a period of time when the battery is very low.
The battery charging indicator should start to scroll after few seconds. But if battery is totally uncharged (empty) it might take up to 15 minutes until charging indicator is displayed on the screen.
In case of a problem,
- If the charging indicator still doesn't start, unplug the cable from the device and plug again, sometimes it helps.
- If your device supports a dedicated charger, check if you succeed charging the battery with the wall outlet connected charger. If that works, it normally indicates that the phone or the battery are not broken.
