Battery Life
One of the strongest attributes of the K9 Jumbo is its 1800 mAh removable Li-Ion battery. The phone promises extended battery life, with up to 300 hours of standby time and up to 6 hours of talk time. This makes it an ideal companion for users who need a phone that can remain functional over several days of typical use without requiring a charge, further aided by the inclusion of a removable battery for quick swaps if needed.
