Hyperion Samsung Galaxy Note 3 9600mAh Extended Battery + Back TPU Cover (Compatible with Verizon Samsung Note 3 / At&t Samsung Galaxy Note III / Sprint Samsung Note 3 / ALL International Samsung Note 3 SM-N900 Models) **Now with NFC/GOOGLE Wallet!!** (Comparable to other 10000mAh batteries) [2 Year Warranty]

If you're deciding between this battery and ZeroLemon's, get this one. They're both 9600mAh and interchangeable, but Hyperion's cover is better. I know because I've owned ZeroLemon's "10,000mAh" battery/cover combo for the past year and resorted to buying this one when the cover began to crack.Since there are no other reviews yet, I'll try to make mine more thorough:--Battery--It's hard to measure, but this battery does seem to have 3x the standard capacity. You could realistically take a week-long trip without bringing a charger. With the right apps, you could also drain it completely within a day, but that would take some dedication.Less importantly, the battery is bigger than what's shown in the picture, and 9600mAh (not 9660) is what's printed on the label. It's made of 3 stock-size (3200mAh) cells in a plastic casing shaped to leave no wasted space when put in the phone. The only difference from ZeroLemon's battery is that Hyperion's casing is marginally thicker to hold the NFC circuitry (I think), whereas ZeroLemon tucks it under their label.Oddly, running a demanding app can drain this battery nearly as quickly as the stock battery, but minutes later it will regain some or most of the lost charge. It's as though the "secondary" cells charge the primary one whenever they have a chance. Not exactly what I'd expect from cells connected in parallel (are they?), and that's why measuring the capacity is hard. ZeroLemon's battery acts the same way.By the way: charging the battery works the opposite way -- unplug it too soon, and the reported charge will drop quickly as the primary cell charges the secondary ones. I won't pretend to understand it, but you do need to leave it on the charger a while after it reports 100% to fully charge it.--Cover--The cover, which is 3/4" deep, is what it should be: a piece of TPU that fits very snugly but isn't terribly hard to take off. The volume and power buttons are especially good - as clicky as if they weren't covered at all. My only nitpick is that the Note 3's shiny rim often shows at the bottom edge; it could fit better at that end. But overall, it's a good fit.Compared to ZeroLemon's Otterbox-like case, Hyperion's TPU cover is less bulky, its buttons are easier to press, and speakerphone mode works better (people complained that I sounded muffled with ZeroLemon's case).Really, I don't know why ZeroLemon decided to over-complicate their battery cover, but I'm glad Hyperion saw the opportunity to make something better.

5 stars for the manufacturing for both battery and especially case however the battery power is a bit wonky. I've noticed for the past and beginning week of ownership the power comes in stages instead of a straight forward access to power. It might just be my imagination but based on the manufactures recommended break-in process and how the battery reacts to charging I'd say it's likely sets (plural) of batteries tied into one as opposed to one big block of batteries. Especially evident how it charges to 100% repeatedly dropping then hitting 100% over and over hours after it reaches full recharge. Keep in mind I'm inside the break-in period.Make sure to keep it on the charger for a few hours after reaching "full capacity".With that being said the battery is absolutely an upgrade in terms of longevity as compared to OEM battery. Couldn't take pics of phone or battery as I use my phone for all pics. Online pic very accurate and the feel, tight fit and weight very nice. Not feeling like made in China although likely was. A bit heavy like a tank but solid - nothing jiggling about. I personally like that feel. Added bonus, for the first time I was able to remove my screen protector as the case does have a small lip rising above the surface of the screen. Can't begin to say how nice that original clean defined screen looks now plus the fact that the worn edges of my phone are completely covered. Basically a brand new looking phone, long performance and super bright, clear images on screen make for a very happy customer. Not sure I can fault the manufacturer for the performance as I'm not sure anyone has anything better so 5 stars.

Battery: it's really like having 3 batteries in one. Just have to charge until the phone actually says fully charged and to unplug charger. That is usually a couple of hours after the battery reaches 100%.Battery warranty: This one says 2 years vs Zerolemon's 180 days (6 months).Battery cover: just wished the bottom lip is tighter fitting. Even then, I personally prefer this case to the Zerolemon case, the later is more rigid and about 2 or 3 cm taller and slightly thicker. Hyperion's case is smaller and has a softer feel.Custom service: their customer service is crazy good! I complained about the cover having a slightly loose lower lip and a battery that has a slight give in one of the corners and wanted to return the item, but instead was offered a full refund and to trash the item, which is otherwise fully functional.

I was torn between this and the zero lemon battery/case. The battery life is excellent but the case of the zero lemon is worlds ahead of the hyperion case. Given the chance I would probably buy the zero lemon over this one.

Great investment for your power hungry bloatware taxed Note 3. I get about 24-30hrs of life out of one charge. I use my phone a lot throughout the day. Great battery, and the case that comes with it is solid but ugly. I have dropped my phone several times and it has survived everytime. I would recommend it

Been using this for a month now and its amazing.I read a lot about extended batteries and also I have seen how poor Zerolemon's cases are (as my friend had one and was crying about the case)So I decided to get Hyperion via a friend who was coming back to India from US. The case is perfect and provides a nice grip to hold.I get a 20 hour Screen ON time (more than 10 hours of it in mobile data).Ordered it long back and my friend reached home a month back and I am using it from then...

Great product for the price removes my anxiety of not having enough battery life. Furthermore, after testing the battery it is actually 10000mAh I guess they are just being conservative with there numbers just in case someone was wondering.
