If you've already got an HTC One, news of a Sense-free version will have been interesting for the presence of Android 4.2.2, as much as anything else. While we can't tell you when your handset will get updated, we can tell you that it'll bring with it some useful additions. A popular one will be the percentage battery level indicator that you see above. There's also extended quick settings, a long-press-for-menu on the home button, Android Daydream, and some changes to the app drawer (remove icons from the dock etc.). So that's the what, we're just waiting for the when.
