Charging indicator on the battery pack
A red light comes on when charging starts. The light turns green, after about 3 hours, when charging is complete. But, it may vary depending on certain conditions e.g. If your phone is switched on or temperature is beyond operational range. As an energy saving measure, disconnect the AC adaptor from the mains socket and from the phone after charging.
The battery icon on the display indicates charging status. When the battery is almost completely charged, the battery icon shows all bars. However, this display shows an approximate indication only, check the indicator on the battery pack (refer to the above) to confirm whether or not the battery pack is fully charged.
