Transformer Prime Gets Battery Improvements with System Update 22.214.171.124
Early this morning XDA Junior Member Liferules reported in our forums that a new update had appeared for his Asus Transformer Prime. Since the previous update (126.96.36.199), intended to improve GPS performance, Prime users have experienced random restarts and decreased battery life. XDA Senior Member demandarin, shortly after the release of the update, posted this screenshot, showing the system using the previously disabled low-power CPU frequencies. Countless other posters confirmed improved battery life and several even claimed improved WiFi performance (not confirmed).
If you are a rooted Transformer Prime user out there make sure you use OTA Root Keeper to maintain root access after the OTA update. Please also note that you WILLl lose root even with Root Keeper if you install the update using anything but the official over-the-air update. Updating using extracted blob files will break root no matter what.
Most users that received the update already were in the United States with the exception of a few users in Mexico. European Prime owners, sit tight. Representatives from Asus have confirmed that the EU version of the device will get the update early next week. Already installed the update?
