Battery Life
The GF 388 is powered by a removable NiMH 915 mAh battery. For that era, its battery life was reasonable, offering up to 37 hours of stand-by time and up to 125 minutes of talk time. This made the phone suitable for a typical day's use, provided one wasn’t constantly making calls. The removable nature of the battery was a plus, allowing users to carry spares if necessary.
