Why battery icon is white in the new 4.4.2 update for HTC One

The answer is actually pretty easy for this:

  1. It’s how Google have designed Android 4.4 to be.
  2. Google have with 4.4 introduced design guidelines for makers using Google Android, more or less “if you want to use android (including Play store, this is the conditions for that”. I think that it’s for users to not be confused over what Android is and so on. HTC have with current Sense version moved closer to how Google designed Android.
