INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Techniques described herein may be used to conserver battery power of an Internet of Things (IoT) tracker by increasing the overall amount of time that the IoT tracker is in a battery conservation mode (a sleep mode, a Power Save Mode (PSM), etc.). An IoT tracker may implement a battery conservation policy that may include instructions that cause the IoT tracker to monitor certain conditions, determine when the conditions satisfy a particular trigger, and implement a battery conservation mode in response to those conditions. Examples of such conditions may include (1) the IoT tracker being close to a user device designated to track the location of the IoT tracker, (2) identifying that a current time and day are associated with a pre-selected schedule for disabling tracking services, (3) the IoT tracker being located within a particular geographic area, and more. ## Claims ### Claim 1 A device, comprising: one or more processors configured to: monitor a proximity of the device to a particular User Equipment (“UE”); determine, based on the monitoring, that a first proximity of the device to the particular UE exceeds a threshold proximity; based on determining that the first proximity exceeds the threshold proximity, monitor a geographical location of the device; subsequently determine, based on further monitoring of the proximity to the particular UE or based on the monitoring of the geographical location of the device, that a second proximity to the particular UE does not exceed the threshold proximity; and based on the subsequent determination that the second proximity to the particular UE does not exceed the threshold proximity, cease monitoring the geographical location of the device. ### Claim 2 (depends on 1) The device of claim 1, wherein ceasing monitoring the geographical location of the device includes entering a power conservation mode. ### Claim 3 (depends on 2) The device of claim 2, wherein the one or more processors are further configured to: exit the power conservation mode after entering the power conservation mode, wherein exiting the power conservation mode includes further continuing to monitor the geographical location of the device. ### Claim 4 (depends on 2) The device of claim 2, wherein the power conservation mode is a first power conservation mode, wherein the one or more processors are further configured to: exit the first power conservation mode after entering the first power conservation mode; determine, after exiting the first power conservation mode, that a particular trigger condition has been met; and based on determining that the particular trigger condition has been met, enter a second power conservation mode that is different from the first power conservation mode. ### Claim 5 (depends on 4) The device of claim 4, wherein the second power conservation mode includes a particular interval at which the device monitors a geographical location of the device. ### Claim 6 (depends on 1) The device of claim 1, wherein ceasing to monitor the geographical location of the device consumes less battery power of the device than monitoring, by the device, the geographical location of the device. ### Claim 7 (depends on 1) The device of claim 1, wherein ceasing monitoring the geographical location of the device includes entering a power conservation mode, wherein the one or more processors are further configured to: exit the power conservation mode after entering the power conservation mode, wherein exiting the power conservation mode includes further continuing to monitor the geographical location of the device; determine, after exiting the power conservation mode, that a measure of acceleration associated with the device is below a threshold measure of acceleration; and enter the power conservation mode based on determining that the measure of acceleration associated with the device is below the threshold measure of acceleration. ### Claim 8 A non-transitory computer-readable medium, storing a plurality of processor-executable instructions to: monitor a proximity of a device to a particular User Equipment (“UE”); determine, based on the monitoring, that a first proximity of the device to the particular UE exceeds a threshold proximity; based on determining that the first proximity exceeds the threshold proximity, cause the device to monitor a geographical location of the device; subsequently determine, based on further monitoring of the proximity to the particular UE or based on the monitoring of the geographical location of the device, that a second proximity to the particular UE does not exceed the threshold proximity; and based on the subsequent determination that the second proximity to the particular UE does not exceed the threshold proximity, cause the device to cease monitoring the geographical location of the device. ### Claim 9 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein ceasing monitoring the geographical location of the device includes entering a power conservation mode. ### Claim 10 (depends on 9) The non-transitory computer-readable medium of claim 9, wherein the plurality of processor-executable instructions further include processor-executable instructions to: cause the device to exit the power conservation mode after entering the power conservation mode, wherein exiting the power conservation mode includes further continuing to monitor the geographical location of the device. ### Claim 11 (depends on 9) The non-transitory computer-readable medium of claim 9, wherein the power conservation mode is a first power conservation mode, wherein the plurality of processor-executable instructions further include processor-executable instructions to: exit the first power conservation mode after entering the first power conservation mode;
