**Update**

(To user: Joe_6pak)

Since I posted my response a while ago (the one you quoted me) about "using a thick piece of paper as a shim".... I have since gotten rid of that "shim" AND ZeroLemon 7500 mAh extended battery and have bought the Anker 7800 mAh 3.8v extended battery for my S4 with the ZeroLemon ZeroShock Rugged case for it in the all-black color.

Check them out and see what they look like here:

Reason for switching to an even bigger battery:

Shortly after I made that shim, through regular movements on the job my phone would still randomly shut off... but significantly less often. I figured out that after about 2 months of those regular movements on the job, the paper shim I had created and put at the bottom of the battery in that tiny 2/10 of a MM gap began to wear away. I then created another paper shim, then it too failed after about 2 months. By that point I was severely aggravated. So after searching through the "Phone Cases & Accessories" thread here in the S4 forums on XDA and going through about 20'ish pages at 35 or so results per page, I finally found a thread where the topic was something to the effect of "Cases that fit 7500 mAh extended batteries." In that particular thread there were a couple guys who stated basically the same exact thing I state below... in that the ZeroLemon ZeroShock Rugged case fits, and it'll be a very tight fit, but your phone will NEVER unintentionally shut off ever again." When I read that, I felt relieved and anxious to see if what those guys said really worked... and it did! So read below for details on fitment....

FYI:

Even though there is a (300 mAh) size difference between Anker's 7800 mAh extended battery and what ZeroLemon's ZeroShock Rugged case says on their website of the max battery size the case can hold, when you press-fit the 7800 mAh extended battery to the back of your phone and you put on the hard shell casing from the ZeroLemon case onto the back of the phone, there's a gap difference of -0.002!! I give a negative number here because the fit is to tight, it bulges out the sides of the hard shell by such a small percentage/fraction that it's barely noticable but is still nothing to worry about because of how well the hard shell is built.

That extra 300 mAh difference between the what the hard shell can hold and the amperage of the Anker bettery accounts for the gap that you would have had/currently still have with the ZeroLemon 7500 mAh extended battery. So being that the Anker 7800 mAh extended battery is a hair wider and longer, their battery removes the need for a "shim" because 7800 mAh is truly the absolute max that the ZeroLemon ZeroShock Rugged case can cold! It will be a very tight fit, moreso than a sumo in spandex, but your S4's extended Anker battery will fit on the back of your phone and the battery will fit inside the ZeroLemon ZSR case without any problems whatsoever... even fix the "turning off" issue!!

P.S. - Trust me... I've done some pretty nasty, evil, physically abusive things to my phone over the years that would make Samsung sweat like a whore in a church but my phone has survived and STILL has yet to have any kind of scratch, dent, or crack in the screen... it would even pass a magnifying glass inspection test!! Plus the TPU outer case is not like the usual make-up or build quality of many other crappy TPU cases from other well-known manufacturers like Hyperion, the TPU case is more along the quality of the sidewall rubber from a car tire. On top of that, the outer TPU case has both of the proper holes for the charging and headphone ports but the cut-outs for them are larger than all other manufacturer's AND they are covered by a flip-top built within the case!

To name a few of the abusive things I've done:

- Dropped my phone on its face and on its back numerous times from heights as high as an 8 foot ladder and went to pick it up and it's still on

- I've intentionally tossed it against the wall from about 4 feet away and let it hit the floor (for durability, strength, and shock testing the case). When I went to pick it up, most of the time it shut off and I restarted it without any problem, the other half of the time it was still on.

- Fast tossed it on my bed from across the room (10'ish feet away) but it slid off the bed and ended up hitting the wall kinda hard and dropping to the floor and it's still on when I picked it up.

- Has fallen out of the seat or the side of my pocket when getting out of my 4x2 Dodge Ram 1500 (non-lifted) truck without turning off.

Sooooo..... I'd HIGHLY suggest EVERYONE to buy the ZeroLemon ZeroShock case if they have an extended battery of 7500-7800 mAh for their S4 because it's like an Otterbox Case but waaaay better!! Think of the Otterbox case on steroids! I LOVE THIS THING!!!

Sorry for such a long read, I got excited.
