A method of receiving e-mail by a mobile terminal, the method comprising: determining one of a split receiving mode and an entire receiving mode as an e-mail receiving mode of the mobile terminal, said determination being based on either an e-mail receiving environment of the mobile terminal or an e-mail utilization pattern of a user of the mobile terminal; and operating in the determined e-mail receiving mode to receive e-mail, wherein, in the split receiving mode, the mobile terminal receives parts of an e-mail transmitted from a sender and then receives the entire e-mail only when the user requests the mobile terminal to receive the entire e-mail and, in the entire receiving mode, the mobile terminal receives an entire e-mail transmitted from the sender at a time, wherein the e-mail receiving environment is determined by the mobile terminal by analyzing a power consumption of the mobile terminal, the method being characterized in that: the e-mail utilization pattern is determined by the mobile terminal by analyzing a ratio of entire e-mails that are requested by the user to received e-mails, and in that the step of analyzing the power consumption comprises analyzing a consumed current variation to receive e-mail according to e-mail size, in order to obtain a threshold value of an e-mail size at which consumed current begins to vary, wherein the step of determining comprises determining the entire receiving mode as the e-mail receiving mode of the mobile terminal if the threshold value is greater than a calculated average e-mail size. determining one of a split receiving mode and an entire receiving mode as an e-mail receiving mode of the mobile terminal, said determination being based on either an e-mail receiving environment of the mobile terminal or an e-mail utilization pattern of a user of the mobile terminal; and operating in the determined e-mail receiving mode to receive e-mail, wherein, in the split receiving mode, the mobile terminal receives parts of an e-mail transmitted from a sender and then receives the entire e-mail only when the user requests the mobile terminal to receive the entire e-mail and, in the entire receiving mode, the mobile terminal receives an entire e-mail transmitted from the sender at a time, wherein the e-mail receiving environment is determined by the mobile terminal by analyzing a power consumption of the mobile terminal, the method being characterized in that: the e-mail utilization pattern is determined by the mobile terminal by analyzing a ratio of entire e-mails that are requested by the user to received e-mails, and in that the step of analyzing the power consumption comprises analyzing a consumed current variation to receive e-mail according to e-mail size, in order to obtain a threshold value of an e-mail size at which consumed current begins to vary, wherein the step of determining comprises determining the entire receiving mode as the e-mail receiving mode of the mobile terminal if the threshold value is greater than a calculated average e-mail size. the e-mail utilization pattern is determined by the mobile terminal by analyzing a ratio of entire e-mails that are requested by the user to received e-mails, and in that the step of analyzing the power consumption comprises analyzing a consumed current variation to receive e-mail according to e-mail size, in order to obtain a threshold value of an e-mail size at which consumed current begins to vary, wherein the step of determining comprises determining the entire receiving mode as the e-mail receiving mode of the mobile terminal if the threshold value is greater than a calculated average e-mail size.
