currently using s6 edge and i am considering between the note 7 and i7. Strongly leaning towards the i7 because of the battery-geate although the inital plan was to get a note7. then i came across this!!

Samsung 10200mAh Fast Charge Battery Pack - Black
Pass-Through Charging
Charge the battery pack and a device connected to the battery pack overnight with pass-through charging. When a device is attached to the battery pack and the battery pack is being charged from a power outlet, the device will be charged to 100% first and then the battery pack will begin to charge.

i got this battery pack 2 weeks ago and am loving it. 20 mins to get the phone back up to 60% and back to daily routine. dont need to keep a wire dangling from the bag or pocket like someone doing IV drips.lol...I didnt even know it had this feature! will be an amazing feature when you are travelling to only have 1 charger. this feature alone made me to wait for the relaunch of the note 7 samsung needs better marketing. so many features that are not marketed unlike the I7 which basically lots of "big canon" talk...lol

btw, i got a i5 for my work phone and the fast charge on samsung def makes a difference.
