Memory and Battery
Memory on the Celkon C70 is minimalistic, with storage options limited to 500 phonebook contacts and basic call records. However, the dedicated microSDHC card slot allows for expanded storage, which can be used for additional contacts, text messages, and media files. The phone runs on a removable Li-Ion 800 mAh battery, offering up to 200 hours of standby time and nearly 6 hours of talk time—adequate for a device in its category at the time.
