The Transformer Prime was released by Asus in late December last year, and has already got several software updates from the company. In fact, in recent time the Prime is the most updated Android device out there in the market, and that is in a good way.
Now, Asus has again started rolling out another software for the Prime, which apparently improves the battery life of the tablet. Other than this, Asus has not mentioned anything as to what the update changes, but Prime owners should expect the usual performance and stability enhancements. Quite a few Prime owners on XDA are reporting that this new update fixed the random reboots, improved the Wi-Fi performance and the battery life of the tablet noticeably for them. The update breaks root, so use Voodoo OTA Rootkeeper from the Market to preserve root access, after the update is installed.
The software update carries the version number 18.104.22.168, and should be available to all Prime owners effective immediately. The update is being rolled out only in the United States at the moment, so Prime owners in other region of the world might not see the update pop up on their tablet.
