INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Systems and methods for providing e-mail to a mobile client are disclosed. In one example, the method can include receiving, at a server associated with transmitting e-mail to the mobile client, an indication of a battery level in the mobile client. The method can also include comparing the battery level to a threshold level and synchronizing e-mail with the mobile client when the battery level meets the threshold level. The method can further include activating, when the battery level is below the threshold level, a filtered mode for synchronizing e-mail with the mobile client, the filtered mode transmitting fewer than all of the available e-mail messages for the mobile client. ## Claims ### Claim 1 A method for providing e-mail, comprising: receiving, at a gateway server that controls access to an e-mail server, an indication that e-mail messages are available at an e-mail account associated with a first and second user device of a user; storing the new e-mail messages at the gateway server; transmitting e-mail notifications from the gateway server to each of the first and second user devices; receiving, at the gateway server in response to the e-mail notifications, a first indication of a first battery level in the first user device, and a second indication of a second battery level in the second user device, wherein the first and second indications include device identifiers of the first and second user devices, respectively; comparing the first and second battery levels to a threshold level; synchronizing e-mail with the first user device when the first battery level meets the threshold level; activating at the gateway server, when the second battery level is below the threshold level, a filtered mode for synchronizing e-mail with the second user device, the filtered mode transmitting a filtered portion of the available e-mail messages to the second user device; transmitting the unfiltered portion of the available e-mail messages to the second user device when the second battery level is above the threshold level; and deleting the stored e-mail messages from the gateway server based on transmitting the messages to both the first and second user devices. ### Claim 2 (depends on 1) The method of claim 1, wherein the indications of the first and second battery levels comprise a percentage of battery life remaining, and wherein the filtered portion of the available e-mail message is selected by a ranking engine, executing on the gateway server, that ranks each available e-mail message and filters the available e-mail messages based on their respective rankings. ### Claim 3 (depends on 1) The method of claim 1, further comprising receiving a first device identifier for the first user device and receiving a second device identifier for the second user device. ### Claim 4 (depends on 1) The method of claim 1, further comprising executing a neural network based on a plurality of factors to determine whether a new e-mail should be filtered or provided to the second user device during filtered mode. ### Claim 5 (depends on 4) The method of claim 4, further comprising updating weighting factors for inputs to the neural network based on a user's interaction with e-mail. ### Claim 6 A non-transitory, computer-readable medium containing instructions executed by a processor to perform stages for delivering e-mail, the stages comprising: receiving, at a gateway server that controls access to an e-mail server, an indication that e-mail messages are available at an e-mail account associated with a first and second user device of a user; storing the new e-mail messages at the gateway server; transmitting e-mail notifications from the gateway server to each of the first and second user devices; receiving, at the gateway server in response to the e-mail notifications, a first indication of a first battery level in the first user device, and a second indication of a second battery level in the second user device, wherein the first and second indications include device identifiers of the first and second user devices, respectively; comparing the first and second battery levels to a threshold level; synchronizing e-mail with the first user device when the first battery level meets the threshold level; activating at the gateway server, when the second battery level is below the threshold level, a filtered mode for synchronizing e-mail with the second user device, the filtered mode transmitting a filtered portion of the available e-mail messages to the second user device; transmitting the unfiltered portion of the available e-mail messages to the second user device when the second battery level is above the threshold level; and deleting the stored e-mail messages from the gateway server based on transmitting the messages to both the first and second user devices. ### Claim 7 (depends on 6) The computer-readable medium of claim 6, wherein the indications of the first and second battery levels comprise a percentage of battery life remaining. ### Claim 8 (depends on 6) The computer-readable medium of claim 6, wherein the stages further comprise receiving a first device identifier for the first user device and receiving a second device identifier for the second user device. ### Claim 9 (depends on 6) The computer-readable medium of claim 6, wherein the stages further comprise executing a neural network based on a plurality of factors to determine whether a new e-mail should be filtered or provided to the second user device during filtered mode. ### Claim 10 (depends on 9) The computer-readable medium of claim 9, wherein the stages further comprise updating weighting factors for inputs to the neural network based on a user's interaction with e-mail. ### Claim 11 A gateway server for controlling access to an e-mail server, wherein the gateway server: receives an indication that e-mail messages are available at an e-mail account associated with a first and second user device of a user; stores the new e-mail messages at the gateway server; transmits e-mail notifications from the gateway server to each of the first and second user devices; receives, in response to the e-mail notifications, a first indication of a first battery level in the first user device and a second indication of a second battery level in the second user device, wherein the first and second indications include device identifiers of the first and second user devices, respectively; compares the first and second battery levels to a threshold level; synchronizes e-mail with the first user device when the first battery level meets the threshold level; activates at the gateway server, when the second battery level is below the threshold level, a filtered mode for synchronizing e-mail with the second user device, the filtered mode transmitting a filtered portion of the available e-mail messages to the second user device; transmits the unfiltered portion of the available e-mail messages to the second user device when the second battery level is above the threshold level; and deletes the stored e-mail messages from the gateway server based on transmitting the messages to both the first and second user devices. ### Claim 12 (depends on 11) The system of claim 11, wherein the indications of the first and second battery levels comprise a low level or a high level. ### Claim 13 (depends on 11) The system of claim 11, wherein the gateway server further receives a command from the second user device to override the filtered mode. ### Claim 14 (depends on 11) The system of claim 11, wherein the gateway server further executes a neural network based on a plurality of factors to determine whether a new e-mail should be filtered or provided to the second user device during filtered mode.
