5.0 out of 5 stars Long life 15 Dec. 2013
Colour Name:White| Size:5200mAh|Verified Purchase
Absolutely great product, battery lasts for 3 days now instead of 1 with heavy use. Great value especially when the samsung battery that came with the phone swelled up and stopped working after only 1 month of getting my new S4. Highly recommended.

Colour Name:Black| Size:5200mAh|Verified Purchase
This has got to me one of the most useful accessories I have ever purchased for a phone. Before buying this, I could only get to about 4 pm every day without having to plug in my Samsung battery on its better days. God forbid if I was away from home without a charger or charging cable. If I knew I couldn't rely on getting a mains outlet to charge the old battery, I would actually lug a laptop around just to plug my phone in.

Now, I can go a bit more than 3 days without a charge and with my regular usage. The protective backing that comes with it wraps completely around the edges (although maybe not the best at the point where it covers the lefthand side buttons, where the edge of the phone is slightly exposed - but that really doesn't detract from its usefulness) and it is flexible and similar in material to the one I was using before.

Only drawback is that it makes the phone a bit thicker and definitely heavier, but for me it beats having to lug around a laptop to charge it up. Would not hesitate to recommend this.

5.0 out of 5 stars Quality product by Anker - 5200mAh GS4 battery 12 July 2013
By Naz87
Colour Name:Black| Size:5200mAh|Verified Purchase
The 5200 mAh battery I ordered was delivered to me for free within two day.

Now, the packaging was excellent and the battery and case were sealed. Having drained the battery once and fully charged it, it has lasted me for more then 2.5x the original 2600mAh battery Samsung provided. I don't know if this is related or if it is simply too soon to tell, but I have noticed that the rate of discharge and also, I have noticed my phone doesn't become as hot as it used to, even when I am using my sat nav (which I do regularly). It is quick charging up, and fits perfectly into the battery slot of the s4.

Few things about the back cover,it is quite slippery, especially to begin with, however, after a while you become used to gripping the phone properly, and I think oil from your hands make it a little easier to grip after a while. Another thing is, I can't find a protective case for the edges of the phone that would fit with the new back cover. However, It is slimmer then I thought it would be (albeit, still quite thick if you are used to the slim original S4 battery). As someone with big hands, it makes the phone a little easier to handle I think, especially if I want to do things with one hand.

Overall, benefits definitely outweigh the cons, and I have recommended this product to many of my friends who are considering upgrading their batteries.

5.0 out of 5 stars Very Powerful 4 Sept. 2014
Colour Name:Black|Size:7800mAh
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.

5.0 out of 5 stars So far brilliant... 19 Aug. 2013
By Rangell
Colour Name:Black| Size: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...

This is one hell of a battery. I'm never down to under 60% in one day with HEAVY usage.
