I have found that after having high idle usage. I searched and found a command that disabled SmartSearch from doing its CPU consuming rubbish, here is the command, it may help Code: devel-su rootme chmod -x /usr/bin/smartsearch /sbin/reboot Your device will reboot and then play around and check out if your Idle decreases, it has dramatically descreased my Idle usage, from 50-60mA to 14-23mA
devel-su rootme chmod -x /usr/bin/smartsearch /sbin/reboot
