5.0 out of 5 stars So far brilliant... 19 Aug 2013
By Rangell
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...

5.0 out of 5 stars Quality product by Anker - 5200mAh GS4 battery 12 July 2013
By Naz87
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 My S4 is now what it always should have been! 9 Jan 2014
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

5.0 out of 5 stars if you have an S4 then you need this... 9 April 2014
The battery is excellent, it takes a while to fully charge but that's because its MASSIVE, I'm now charging my phone twice a week at most instead of sometimes twice a day... And I use my phone a lot, WiFi on and off, phone calls all day, downloading things etc but this battery handles it well and it means you can also use live wallpapers etc as well, and if your phone isn't rooted and your still on the battery heavy stock ROM then you really need this. The bigger case that comes with it to enclose the battery is actually quite good as the flat, original one was quite slippery, this one makes the phone hold better in my hand, the case can be a little creaky at times, it should have been filled inside better as its a bit hollow, but as a free add on with this battery, which is cheap for what it is, it's worth it.

5.0 out of 5 stars Fantastic battery life 27 Jan 2014
Verified Purchase
It looks a little bulky but in practice it doesn't really affect anything. The battery life is so brilliant, I used to barely get a full days use out of the original battery as I am constantly on the phone through out the whole day. With this extended battery I can easily get a full days use without having to charge it mid way through the day. An excellent purchase.

I thought my phone was faulty as my phone as it kept turning off each time I tried to restart and when the battery was showing 80% full. I also couldn't phone people or listening to Spotify as it said it couldn't find a connection, even though I have it on offline mode.I did some research on the problem and discovered that the S4 has a common battery drain issue. However, the normal working S4 battery is still rubbish when you try to do normal things in a day like using Facebook/messenger apps or taking pictures. My battery always died in the middle of a night out, just from listening to music on a half hour journey, checking FB a few times and taking half a dozen pics. My battery often wouldn't make the journey home.

So I looked into alternatives and Anker was suggested. There were the standard S4 battery, the 5200 mAH and the 7200 mAh batteries. The 7200 get amazing reviews but time and again people said it wasn't the most portable so that eliminated that one. I did see that the 2600 lasts longer than the standard Samsung battery but not enough for my requirements. It seemed that the 5200 would be a happier medium. Sure, it's definitely a bit bulkier but not prohibitively so, BUT it is overridden by the fact that the battery last ridiculously longer than the standard S4 battery.

I gave it its first full charge the day it arrived and I started using it at half 5 in the morning. I was on Facebook, Messenger and my twitter app as well as using Chrome. I used it for about an hour and a half pretty solidly. I picked the phone back up at around 10 am and I was using it all day on numerous apps, as well as downloading apps, taking lots of photos and listening to music. At around 7pm my battery was at 14%.
