an auxiliary battery; a cover removal sensor for sensing a removal of a battery cover; and a controller configured to: responsive to a first signal from the cover removal sensor that indicates that the battery cover is removed: (i) transmit, over a communications network comprising a base station configured to establish a communication session between the apparatus and a terminal, a first signal requesting standby mode transition and release of the communication session between the apparatus and the base station while maintaining the communication session between the base station and the terminal and (ii) switch from operating on power supplied by the main battery to operating on power supplied by the auxiliary battery; switch the apparatus from operating on power supplied by the auxiliary battery to operating on power supplied by a replaced main battery when the main battery is replaced; and transmit, over the communications network, a second signal requesting re-establishment of the communication session between the base station and the apparatus in response to a received voltage from the replaced main battery. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the auxiliary battery supplies power to fewer than all components of the apparatus. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the controller is further configured to detect whether the main battery is replaced within a predetermined time period. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the communications session includes a telephone call. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the first signal is generated by the cover removal sensor when the battery cover is removed. ### Claim 6 A method for battery replacement in an electronic device having a main battery and an auxiliary battery, comprising: responsive to a first signal from a cover removal sensor that indicates that a battery cover is removed: (i) transmit, over a communications network comprising a base station configured to establish a communication session between the electronic device and a terminal, a first signal requesting standby mode transition and release of the communication session between the electronic device and the base station while maintaining the communication session between the base station and the terminal and (ii) switch from operating on power supplied by the main battery to operating on power supplied by the auxiliary battery; switch the apparatus from operating on power supplied by the auxiliary battery to operating on power supplied by a replaced main battery when the main battery is replaced; and transmit, over the communications network, a second signal requesting re-establishment of the communication session between the base station and the electronic device in response to a received voltage from the replaced main battery. ### Claim 7 (depends on 6) The method of claim 6, wherein the auxiliary battery supplies power to fewer than all components of the electronic device. ### Claim 8 (depends on 6) The method of claim 6, further comprising detecting whether the main battery is replaced within a predetermined time period. ### Claim 9 (depends on 6) The method of claim 6, wherein the communications session includes a telephone call. ### Claim 10 (depends on 6) The method of claim 6, wherein the removal of the battery cover is sensed by a cover sensor that is part of the electronic device.
