AT&T's version of the HTC One M8 is receiving a small update today, bringing the Extreme Power Saving mode feature to the phone. Though other models of the One M8 launched with the Extreme Power Saving mode, U.S. carrier versions were sent out the door before the feature could be enabled. Today it's AT&T's turn to push out the update (following up behind Sprint), and following confirmation earlier in the week that it would be heading out, members in our forums are starting to see the update already.
And the broken Google Drive space is now fixed.
It isn't clear whether the update brings any other features or fixes, but the main item in the spotlight here is the EPS mode. Seeing the update yet on your own AT&T HTC One M8? Be sure to hop into the forums and let everyone else know how you're getting along with the latest software.
