Why the xbee-pro 900hp drains 25ma in synchronous sleep mode

0 votes
The network is configure in synchrounous sleep with 1 coordinator set with SM(7) and 25 remote set with SM(8). The grove module alone drains only 7ma and 25ma with the xbee module sleeping mode.
At txPL (PL 0) current drain is 50ma.
The mesh network works fine with a coordinator and 25 remote. Each remote unit read 2 analog temperature sensor and one analog humidity sensor. These 3 sensors drains less then 1ma. The remotes XBee AA battery have to be change around every 100 hours. Any suggestion to get a lower power drain on battery
Regards.

Disable any unused pull up resistors and pull down resistors. Then set all unused IO lines to Input.
