What feature would you like to see in the DualShock 5?


So as most of you know, the DualShock 5 will be released alongside the next PlayStation. What cool new features would you like to see with it? Do you think Sony will be adding a new unknown feature? Or will they try to keep it as similar to the DS4 as much as possible?
I really want them to remove that light bar on it, if nothing else just add a better battery. Seems like my controller loses a charge so easily these days, unlike my DS3.
