I was hoping the accessory battery attachment might remedy at least some of this. It does provide a more comfortable grip, particularly with holding the camera in vertical format, and adds and extra set of front and back control knobs.
With an extra battery in the grip it weighs 7.4oz. Doesn't sound like much until you realize that the X-T1 camera with battery and memory card installed weighs in at 15.52oz. In other words, the battery grip with battery weighs about half as much as the entire camera with its battery. That's a lot considering the battery itself only weighs 1.6oz.
I am quite conservative when it comes to adding any bulk to a camera I have to carry around and work with all day. This includes battery grips. Some of the original Nikon grips not only added extra power, but boosted the motor drive rate also. That day is long gone. Today, grips add an extra battery and extra bulk plus the purported extra comfort of holding the camera and controlling it in its vertical position. I am not totally convinced about the advantage of this, although I have to admit that over a long day I have found that a grip accessory on a Nikon D800 and D600 has added to the comfort level of using them for an extended period of time. Will the same be true of the Fuji X-T1? I hope so. I will be using the camera with grip for a couple of full lifestyle shoots shortly and will report my findings with an addendum to this review. In the interim, I can say the grip adds a more substantive look to the camera and adds some necessary bulk to a very small body. On top of that, you gain an extra battery to prolong the shooting day.
One nice thing is that the accessory battery is the first one used by the camera so it will run down first and can be replaced before you ever even switch to the main camera battery. If you do happen to wear both batteries down, changing the set will mean unscrewing the battery grip to first access the main camera battery.
Is adding the grip more convenient than simply tossing a few extra batteries in your pocket? Probably not. In fact the batteries, themselves, are much smaller and lighter to carry around. So you are really going to have to like the look and feel of the grip itself for it to make sense for you.
For me, the simple hand grip accessory might end up being a better option because of its convenient, built-in Arca-Swiss plate and cutout for access to the main battery compartment.
