可见，采用本方面所示的充电方法，所述第一电子设备能够根据第一电子设备的第一使用时长和第二电子设备的使用时长，自动判断出供电方和受电方，在充电的过程中无需用户的手动操作，从而有效的提高了充电效率。而且通过使用时长判断供电方和受电方，从而使得确定供电方和受电方的过程中，充分的考虑到了第一电子设备的使用程度，例如，虽然第一电子设备的剩余电量比较大，但是，该第一电子设备运行了多个耗电量大的应用，即该第一电子设备的使用程度非常重，若使得该第一电子设备作为供电方为其他电子设备进行供电，则会导致该第一电子设备后续无法正常使用的情况的出现，而采用本方面所示的方法，通过使用时长确定供电方和受电方，避免了使用程度重的第一电子设备为使用程 度轻的第一电子设备进行供电的情况的出现，有效的保障了第一电子设备的正常使用。

采用本方面所示的方法，所述第一电子设备可根据过去一段时间(即第一时间段)内，所述第一电子设备的第一电池电量的变化量和所述第一时间段确定出所述工作电流，从而使得第一电子设备能够基于该第一电子设备在已过去的第一时间段内的电池电量的变化量，估计出第一电子设备的第一使用时长。

基于本发明实施例第一方面，本发明实施例第一方面的一种可选的实现方式中，所述方法还包括：所述第一电子设备获取第二时间段，所述第二时间段的时间起点为当前时刻或位于所述当前时刻之后的时刻；所述第一电子设备根据所述第二时间段获取对应的第三时间段，所述第三时间段的起始时刻和结束时刻与所述第二时间段的起始时刻和结束时刻 相同，且所述第三时间段所位于的日期早于所述第二时间段所位于的日期；所述第一电子设备在确定所述第一电子设备在所述第三时间段内运行目标应用的情况下，触发执行所述第一电子设备确定所述第一电子设备处于正向充电模式的步骤，所述目标应用为运行电量大于或等于预设值的应用。
采用本实施例所示的方法，所述第一电子设备充分考虑到了未来时间段内是否有可能运行有耗电量大的目标应用，若第一电子设备的第一使用时长大于第二设备的第二使用时长，但是第一电子设备在未来时间段(第三时间段)内运行目标应用的概率非常大，则使得第一电子设备作为供电方后，无法在第三时间段内保障第一电子设备成功运行目标应用，可见，采用本实施例所示的方法，能够充分保障目标应用的运行，避免了第一电子设备因作为供电方，无法正常使用目标应用的情况的出现。

采用本方面所示的方法，若所述第一电子设备确定出所述第一使用时长和所述第二使用时长相等，则所述第一电子设备确定所述第一电子设备处于待机模式，即所述第一电子 设备不为所述第二电子设备充电，也不用第二电子设备为第一电子设备进行充电，从而避免了对第一电子设备的电量的耗费。

为使得采用本实施例所示的充电方法，在无需用户手动操作的情况下，即可实现所述第一电子设备和第二电子设备之间的互充，则需要第一电子设备确定出，第一电子设备和第二电子设备之间，作为供电方的电子设备以及作为受电方的电子设备，具体确定过程如下：
所述第一电子设备可判断所述第一使用时长是否大于所述第二使用时长，若所述第一使用时长大于所述第二使用时长，则说明所述第一电子设备能够正常使用的时长大于所述第二电子设备能够正常使用的时长，所述第一电子设备即可作为供电方为所述第二电子设备进行充电；
若所述第一使用时长小于所述第二使用时长，则说明所述第一电子设备能够正常使用的时长小于所述第二电子设备能够正常使用的时长，所述第一电子设备即可作为受电方，第二电子设备为所述第一电子设备进行充电。
步骤305、所述第一电子设备确定所述第一电子设备处于反向充电模式。
本实施例中，若所述第一电子设备确定出所述第一使用时长大于所述第二使用时长，则所述第一电子设备即可确定出所述第一电子设备处于反向充电模式，所述反向充电模式是指，所述第一电子设备对所述第二电子设备输出充电电流，可见，此时的所述第一电子设备为供电方。

而且采用本实施例所示的充电方法，所述第一电子设备能够根据第一电子设备的第一使用时长和第二电子设备的使用时长，自动判断出供电方和受电方，在充电的过程中无需用户的手动操作，从而有效的提高了充电效率；
而且通过使用时长判断供电方和受电方，从而使得确定供电方和受电方的过程中，充分的考虑到了电子设备的使用程度，例如，虽然电子设备的剩余电量比较大，但是，该电子设备运行了多个耗电量大的应用，即该电子设备的使用程度非常重，若使得该电子设备作为供电方为其他电子设备进行供电，则会导致该电子设备后续无法正常使用的情况的出现，而采用本实施例所示的方法，通过使用时长确定供电方和受电方，避免了使用程度重的电子设备为使用程度轻的电子设备进行供电的情况的出现，有效的保障了电子设备的正常使用。
以下结合图4所示，对本实施例所示的充电方法的另一种实现过程进行示例性说明：

本实施例对所述目标应用的具体应用类型不做限定，只要所述目标应用为运行电量大于或等于预设值的应用即可，例如，所述目标应用为视频类应用、导航类应用等。
步骤408、所述第一电子设备确定所述第一电子设备处于正向充电模式。
可选的，若经由步骤404，所述第一电子设备确定所述第一使用时长小于所述第二使用时长，则所述第一电子设备确定所述第一电子设备处于正向充电模式，所述正向充电模式为所述第一电子设备接收所述第二电子设备输出的充电电流，可见，此时的所述第一电子设备为受电方。

采用本实施例所示的方法，所述第一电子设备充分考虑到了未来时间段内是否有可能运行有耗电量大的目标应用，如下班时间段内的视频类应用，如早高峰时间段内的导航类应用等，若第一电子设备的第一使用时长大于第二设备的第二使用时长，但是第一电子设备在未来时间段(第三时间段)内运行目标应用的概率非常大，则使得第一电子设备作为供电方后，无法在第三时间段内保障第一电子设备成功运行目标应用，可见，采用本实施例所示的方法，能够充分保障目标应用的运行，避免了第一电子设备因作为供电方，无法正常使用目标应用的情况的出现。
