Why should I purchase this if the battery size is the same as a default GS4? (2600 mAh)

It is something about the battery that comes with the case that makes it works properly. I have had it for about two or three months, and I have not yet had any problems with this case. I am very satisfied with it. I will encourage anyone who wants longer battery usage to purchase this. I hope this will help you in making up your mind.

It has two batteries...one built into the case, and the other (which it comes with) replaces the battery presently in your phone.

I dont know that you should purchase it. My boyfriend loves it because it gives him twice the battery life (His phone was always going dead). This is like a backup battery from the way he explains it.

It has 2 batteries, one that replaces the 2600mAh stock battery and an additional 3000mAh that is built into the case itself. It greatly increases the battery life and has been a big help to me. It's also much thinner than many other battery cases out there. It took a little while for me to get used to the flip cover but I like the protection it offers. The only negative that I have found so far (using this product for 3 months now) is that it doesn't have NFC since the antenna is built into the stock battery. There are external NFC antennas that you can get if this is a feature you use regularly though so it's not a huge negative for me.

Basically it is 2 batteries in 1 is my best answer. Personally I don't care for the flip cover it's a big hassle

It doubles the current battery on your phone and it really works. I also like the flip cover because it protects the screen and I find it easy to use.

I only have the SZ 7, which would appear to be a newer version of the SZ line. Check the power requirements. MAh (milliamphours) can vary--usually the more the better--but see if the voltage output is the same. Then you should be OK, as long as they haven't changed the battery size/dimensions. I've been quite pleased with the Wasabi package. Met my needs--as long as I remember to pack a spare on long trips--old geezer brain function issue, not equipment function issue.

The battery is just slightly larger than a regular s4 battery. They may not be the same battery tho, not sure. Fits fine in a regular s4, a little snug though.

I don't know if other carriers S4's are the same. A lot of reviews say other sellers do not ship direct replacements. I do know the one's I bought from fasttelcom it is a direct battery replacement for my S4. Only difference between replacements and original was the serial numbers.

Samsung S3 and S4 are slightly different in size, so it is better to buy the one that is available for that specific model

As others have reported, this is a very common battery. It's an i9300 and you can get great prices here at amazon. It's also available from ibattz (makers of mojo case) and almost any store that sells Samsung cell phones.

The battery measures 2 2/8"by 2 1/2" and was the exact size and as the original in my Galaxy S4. It is as advertised Samsung Original OEM and I have been using it since arrival and it is holding charge well. Hope this helps with your assessment of this replacement.

I have the exact same model and ordered it. It fit but juts out further than the original battery and is heavier. it did hold over 4 hours of time when I charged it.

Samsung sells an alternate battery cover for the GS4 to enable Qi charging. Or you could get an after market receiver of you don't mind the extra bulk.

my wife has the epic 4g (Galaxy S) and it takes the 1500 mAh battery, i am pretty positive that it will not fit, because the 1800 is the same thickness, but wider (because the phone screen is so much bigger on the epic 4g touch (Galaxy S2).

The juice pack is almost like a power bank. You charge it and then it charges your phone, which is lame. The anker 7800 mah is a battery replacement. The battery is a much larger battery that also comes with a case that replaces the back of your phone, which accommodates for the larger battery thickness and also protects the phone. I was weary at first but I can say with 100% confidence at this point that it is amazing, and you should get it. I finally actually use all of the battery draining features that make the s4 what it is. Not trying to sound like an infomercial lol. Just love this thing The juice pack is almost like a power bank.

I have had this problem before...however I would ask that you check the Mah on your phone, if it higher than 2600 Mah that could be a problem! this can be done by removing the battery and looking on the underside, there you'll find the Mah...you may need a larger Mah if this is the case....

My best answer: If the voltage is the same and it physically fits, then it is okay. The 4400mah stands for 4400 milli-amp hours which means that your battery can provide 4.4 amps for 1 hour or 2.2 amps for 2 hours. This means your battery is better than the 4000mah battery. I am forced to assume that the battery pins of the new battery are one for one the same as the old battery.

No. This S4 mini uses a 1900mAh battery and the regular S4 uses a 2600mAh battery. That means the S4 uses a physically bigger battery than the S4 mini. In general it is not usually a good idea to by "mini" or "active" versions of a flagship device. They come with almost insulting specs and overall just not a very good phone. And also it is hard to find accessories/replacement parts for "mini" flagship devices.

Hi, first: I don´t have a S4 (only S3), so I can just guess. If I see it correct a S4 battery have about 2600mA. This powerbank have 7800mA, so it should be between two and three times... Regards, Carmen

I ordered two. They work perfectly. The higher 2400ma means they have more capacity - last longer. However, be careful when ordering. There are two different models with the same part number. Insure that the contacts in the picture looks exactly like the contacts on your current battery.

It's substantially larger (about twice as thick) and heavier (at least twice as heavy) than the original battery. Any case made for use with the standard battery won't fit (but there are cases made for the larger batteries). In my opinion, these trade-offs are worth the extended battery time.
