Users of the ASUS Transformer Prime that received the 184.108.40.206 update, were becoming a little upset that the new update was causing the tablet to restart and suffer huge battery drains. Since then, a 220.127.116.11 update has rolled out, and XDA Senior Member demandarin posted a screenshot showing that his Prime was using the previously disabled low-power CPU frequencies. Other members of the forum also posted that their battery life has improved, so Prime users can relax now. Make sure you use OTA Root Keeper if you are rooted, so when the update comes your Prime will remained rooted.
Any Prime users out there receive this update yet?
