Absolutely... depending on your use your phone will hold twice to three times as long. Look, before the update my OneXp was better on standby times than my 8X, since... the 8X matches or betters the OneXp standby times. And my OneXp also got all the updates. But once the screen is always on, the 8X holds longer than the OneXp, the big screen of the OneXp just eats away the battery. You will see a real big difference.
