Colour Name:Black| Size Name:5200mAh|Verified Purchase
I chose this because it was double the output of the stock item. The S4 guzzles power and the stock item was letting me down half way through the day. So far, I have not come close to draining this battery even with excessive use. I have even set the screen to be brighter with little impact on battery life. The negative thing is also a positive for me. The Anker is twice the thickness of the stock battery (not surprisingly) but they supply a new back cover which make the phone a bit chunkier. For me it actually makes it easier to hold. Of course the pouch I had is no longer any good but I'm delighted with the power of the battery and the new 'feel' to the phone.Now if only they did a protective rubberised casing to protect it...

I was supplied a sample for test and evaluation, and I promised that my review is fair and honest
Equipment used to conduct the review:
Anker 7800mAh Battery
Samsung Galaxy S4
Standard Micro USB cable
Anker 5 Port USB Charging Hub (40W)
Battery Monitor Widget Android App
This product came well packaged in a sturdy cardboard box from Amazon. Inside their packaging is the matte finish box of the Anker battery. The dimensions of the box are approximately 20x15x5cm.
My choice of Android app for monitoring my battery performance is Battery Monitor Widget. This app was used to test this battery too.
The product came approximately 40% charged so I left the phone to charge to 100% before giving it a test run. The initial charge took approximately 12 hours and temperature was within safe levels.
I didn't go out my way to use my phone any differently as I would from normal. A normal day of using the phone includes checking emails, making a few phone calls, using WhatsApp, playing the odd game or so for around 10 minutes and watching some news clips. The battery lasted 35 hours for me from 100% to 0%. Another full charge overnight and another day of usage gave me similar results. The second full charge took approximately 7 hours for me. I use a standard Micro USB cable and an Anker 5 port USB 40W charging hub.
The case fits easily and doesn't affect the functionality of the phone at all. Note that due to the polished finish of the case, there will be a load of finger prints on it. It is inevitable that such a product increases the weight of the phone once fitted however for me, this is not an issue. I have a universal car dock and was able to mount this on my dashboard and charge with no issues. Read more ›

Colour Name:Black|Size Name:7800mAh
Anker provided me this item for evaluation and review, I promise that my review is fair and unbiased.
I was ecstatic when I got this case and battery as my partner has been hounding me to get her one. She watches movies, listens to music and plays games a lot so drains her standard one in under 4 hours.
It came in 50% charged. It took nearly 11 hours to bring it to full charge using a 5V/2.1A charger. It was used as normal; playing games, watching movies.....making calls, and lasted a day and 12 hours on first use then duration of charging time and usage time fell. It takes 4 - 5 hours now to fully charge using the Samsung charger which has a 5V/2A capacity and last roughly a day and 4 hours.
The case fits well around the phone and all buttons function well. One has to be careful when removing the case as it "grabs" hold of the battery. NFC is lost and if you used an S-cover, the screen then becomes exposed. The back of the case is glossy and fingerprint marks were left on it. If you are making a long call you are going to feel the weight of the battery. The size of the case combined with the phone gives it a "unique" look.
The battery is very durable and achieved a high rating on the AnTuTu Tester app. Test was run under 20% power and after test battery was down to 18%.
I recommend to everyone who use their phone intensively.

Colour Name:Black| Size Name:5200mAh|Verified Purchase
I switched from an iPhone to a S4 4g+ (i9506) because I wanted a bigger higher resolution screen. Very happy with the phone except for the severely disappointing battery life. What's the point of top notch hardware if you have to turn everything off and throttle the phone just to make it through the day with out recharging? My phone was running low on power by late afternoon, and going out for dinner would definitely kill the battery. Not cool.
So I ordered the 5200mAh battery from Anker. Sure, my S4 looks like it's expecting a S4 mini, but considering the guy carrying it I don't think it detracts from my "stylishness" too much. In fact, I kind of like the way it looks now. And even if it was hideous, for me the peace of mind would in any case be worth it. No matter how much I use it, important emails etc. will still reach me when I'm enjoying an evening with friends.
To summarize:
+++ for not having to charge at every power outlet in sight
+ back cover fits tight and looks ok
- for being somewhat bulky
- cover is more slippery than the factory cover
Highly recommended

Colour Name:White| Size Name:5200mAh|Verified Purchase
This battery is amazing, seriously. I bought this with very high expectations and it didn't let me down, yeah it may be huge and bulky but I like it to be honest, I feel like it gives me more grip so I can hold the phone easier, ever since I got the battery I haven't dropped my phone once(and trust I've dropped it sooo many times before). Yes it does last a very long time. I use the hell out of my phone everyday, therefore the standard battery that came with the phone only lasted me about half a day at the most, this battery lasts me 2 whole days!! But if I barely use the phone, then it may 3 or 4 days. I recommend charging it for 16 hours when you get it, just like you should with any rechargeable battery, it cycles the battery and helps it to last abit longer.
It is also a great value for money, I feel like this was £20 well spent!
If you have a Galaxy S4 then do yourself a favour, stop using the standard battery then may have a chance of swelling up and runs out very quickly, and buy this beast, you wob't be disappointed trust me! But if you're a fan of how thin the phone is then you might not like how big it makes your phone.
