Why is my new Iphone6s battery not lasting as long as my previous Iphone6 did ?

[iMore Question]

Is there some tricks to help me improve the battery life of my new Iphone6s ? Thanks

It will take a few days for everything to index and settle. You may be playing with your new toy more, too. Are all your settings the same as they were on your 6? If not check those. Also Facebook app has been a known battery drain. I think they just released an update for it yesterday.
