an UnNecessary expense!
Why would you need it on a higher technology device such as the Galaxy Note 4?.... I may want an external battery pack that's compatible with Qualcomm's Quick Charge 2.0 spec (Samsung's adaptive quick charge).

If I'm to spend $60.00 on a big heavy battery of a mediocre life warranty, I would rather my money spent on a battery I can use for other things such as to charge my Bluetooth Headphones

not to mention the case is an awful way to make an expensive $900 smartphone look as if you pulled it from a cereal box!

and my Battery life is
PHENOMENAL!!! SO I WOULD THINK TWICE ON THIS EXPENSE?.. as the previous post of above said would be a smarter choice to get an external battery.
Everyone has their opinion. Some are surprisingly bold in their urging theirs on others.
Nobody really needs it. After all it already has a battery that works. It's simply a matter of preference.
Some would rather not have to bother with lugging around another external battery pack and it's charger and trying to find a way to leave it connected in their pocket or holster while they go about their busy day from place to place hoping they don't accidentally bend the connector over and possibly break the power port on their $900 smartphone that appears to have an insufficient battery life to carry it through the day even though it's "phenomenal".
Some of us don't concern ourselves about others' opinion as to it's looks, weight or bulk. Some of us only care about the device performing based on our particular needs / wants.
And some of us are VERY reluctant to run an app that demands such invasive permissions as
Identity - access to accounts
Location - Precise location (GPS and network-based)
Photos/Media/Files - modify or delete the contents of your USB storage
-test access to protected storage
in order to save battery life.
Why a battery saving app needs my serial #, google ad id#, precise location and ability to modify or delete the contents of my USB storage is concerning to me.
For those of us in that situation, no need to think twice about what fits our preference because the smarter choice for us is to go with what works best for us.
Some would advise that you'd be foolish to spend $900 on a phone when you could just as easily make calls and text from a dumb phone or that if you insist on a smart phone, it would be far more prudent and financially responsible to purchase a Note 2 or other smartphone on ebay or Craigslist for far less money. Yes, it's true, you could get something other than what you really want but you want what
you want.
As for me, I love to hear about others ideas and findings, allowing me to make educated choices about either what I need or just simply want.
That's part of why I decided on the Anker 7800mah extended battery for my Galaxy S4 and the Zero Lemon universal rugged case that would accommodate any size extended battery. Yes, it was a brick but I didn't care 'cause I got the quality battery I wanted with a case that worked. I could also get a day and a half of moderate to heavy usage without having to plug in somewhere. I didn't have the inconvenience of either not having my phone with me as it lay somewhere else charging or carrying my external battery pack around to charge my phone, being very very cautious not to snag the cord and damage the power port on my expensive phone as I get my job done running service calls, up and down ladders, in and out of my van, with frequent need to talk to tech assistance for the product I was working on.
It also saved me the hassles mentioned above while on an overnight hikes where pack weight and unnecessary extra stuff is a consideration.
The best part though is it fit the bill for what I wanted. The "smarter choice" is subjective depending on your needs / wants. Even though for me the smarter choice is to keep my privacy rather than just hand it all over to app developers, and though I won't use it because of the invasive permissions, I appreciate you sharing about the Snapdragon app and your choices regarding charging. It allows me to see the pros and cons, and to learn about more of the multitude of things I am ignorant of to make an educated choice.

I had a Zerolemon for my S4, battery life was phenomenal with it! But it made the phone so huge and heavy, my arm ached when I talked on the phone for more than 10 minutes.
Wow, that's going to make the phone almost an inch thick.
Bluetooth is a wonderful thing.

No need to hold a huge tablet up to your ear.
