Stalion Strength 5200mAh Extended Battery & Back Door Cover for Samsung Galaxy S4 (White Frost)

Shyeet not only did it come in pristine condition, (back cover plastic wrapped and battery encased too!) It's so God Damn Bloody Comfortable! Even with a case on the OG battery the bloody S4 was stupidly uncomfortable for me to hold in hand. Not only that but now it's even easier to grab out of my jeans, skinny or not! (I was confused on this one, but design wise is probably makes sense)oh also for any unfortunate goers like me who had to replace their phone with an old phone (like the s4) this is a perfect, and this also works with the US Cellular S4 (which iirc is closest to the Sprint/T-mobile editions)Good job Stallion you've already out-shined ZeroLemon by 1000 light years!(and yes ;) I did mean distance)I may or may not get the hyperion slipover case since well, the back cover *is* plastic so I can't imagine that staying in my hand for long + it keeps the phone together :\ . but maybe the weight distribution will make it so the base of the phone is directed towards me.pics included to showcase the curvature that fits the hand(*similar to the LG flex,) and the look of it.Will report back with battery drainage since age may be a factor and not Stalion's fault.Edit: 6/12/2016It's been a few weeks and yep I'm definitely happy with what I have rn, the old battery couldn't even last a day (much less 2 hours >:( ) but this 5200mAh can last 1 1/2 day(s) (2 days if you really limit usage!). I do moderate usage so - python IDE work and reddit browsing, it definitely gets an OK from me and I don't see a need for a slipover case now since the base of the weight is at the bottom of the phone and never falls out. (Though any blame I have with the design of the phone has nothing to do with the battery sticking out farther, I just really miss my LG G3 :'( )I'm sure this won't last for longer than a year, but hey it did what I wanted and that's to hold me off until my next phone upgrade/GETTING OFF MY CONTRACTED PLAN

I have added new apps to my phone that required more battery power. I purchased this item because of the other reviews. To say I'm disappointed is really minor as to how I really feel about this. First no instructions came with the battery at all, so I wasn't sure how long to charge it, before 1st use. Next the battery which showed less than 3% charge when I put it in the phone took less that a hour to supposedly fully charge to 100%. I found this strange, because my regular battery takes 3 to 4 hours to reach 75% charge from 3%, and it doesn't have but half the rating of this battery.Needless to say I continued on. My phone started acting strange. It would turn off in the middle of a conversation, it would continually bring up a screen recommending I turn off the phone. I would try to activate an app and the phone would shut down instead, Suddenly apps I have used on a daily basis started giving me error messages and refused to operate.I put up with this for 2 days before I shifted back to my old battery and a miracle happened, all my problems went away. I have been using my old battery for a day now. And have not had one problem, not one 'error' message, all my apps work again like they used to..My opinion is that this battery despite the claims is "Incompatible" with my Galaxy S4 (i545 Verizon). I will eat the cost. But this is the last time.

Last year I bought the more expensive "Other Brand" extended battery and back cover. I was satisfied with it. But after it started not holding a charge, I went looking again for a replacement. I found this Stallion battery for half the price of the Other Brand. Since my phone is up for renewal in 6 months, I decided to try the Stallion. The Stallion is every bit as good and maybe ever better that the more costly brand when it was new. I never got more than two days from the other brand even when new. I am getting 3 days of charge minimum from the Stallion. This is the battery that I will buy for my new phone when I get it.

I've been using this product for almost 2 months and the battery life is nothing short of incredible. I describe myself as a moderate user, mostly calls and texts and occasional internet usage. I have gone up to 3.5 days without charging, but once I hit 10% my phone constantly reminds me to recharge. The fit and finish looks OEM, and for an extended battery it recharges rapidly. It does make your phone thicker but I actually prefer the extra heft as it fits better in my large hand. I also purchased a Hyperion case that fits it like a glove. The NFC function works flawlessly with my spouse's Samsung S5.My last phone (HTC Sensation) lasted me 4 years, and I replaced the batteries several times, and I can say not all aftermarket batteries are what they advertise. I will update this review as the battery ages, but as of now I highly recommend it.
