Product Description

Colour Name: White

Product Description

This battery has a capacity of 3000mAh, which is an additional 900mAh over the stock battery, keeping your Samsung Galaxy S3 going for longer.

Replacement back cover houses the extended battery and protects against damage.

As this battery is bigger in capacity than the standard one, it also has to be bigger in size. To accommodate this, the battery comes with a specially built replacement back cover that houses the battery, while also offering additional protection to the back of your phone from scratches and scrapes. The battery is approximately 1.5mm thicker than the standard battery. As a result the camera will now sit flush with the phone.

Official Samsung product made for the Galaxy S3.

As this battery is an official product made specifically for the Samsung Galaxy S3, it fits perfectly within your phone and is compatible with it. In addition, the replacement back cover offers an excellent fit for your device, and features a cut-out for the camera so you don't lose any functionality by using this battery.

This extended 3000 mAH battery should of been the stock battery they launched with the phone. It only increases the thickness of the phone approximately an extra 2 or 3 millimetres and maybe a few extra grams of weight. Unplugged it from the charger at 9am and now it's 7pm and still has over half charge remaining (52% to be precise) and this was with moderate use, with a fair few rounds of Candy Crush, and Facebook stalking, and the brightness set manually to half-way.

Overall, it's WELL worth the £20 (that I paid at the time) for an OFFICIAL Samsung product. Two thumbs up!

P.S. My old stock battery I now have fully charged as an emergency battery should this ever fail me! Which I doubt it won't! Could even fit in my wallet on a night out to replace the condom I'll never use! Bonus!

I recently acquired a Samsung Galaxy S3 LTE phone and was looking for an extended battery for it.

After a DISASTER with a so-called 'Zero lemon' I was almost going to buy a Mugen power battery as it was a brand I'd had success with in the past. I then stumbled across this.

Admittedly it had less capacity than the Mugen but it was ORIGINAL SAMSUNG,at a third of the price. I was onto a winner.

It was supplied to me in a rather nice dark blue, goes well with my Titanium grey phone giving a classy two tone appearance. Unlike others it does not affect NFC,Bluetooth or Wifi.

It arrived well packed and also supplied with a plastic case for the battery to carry as a spare-an excellent touch.It being an OEM model meant there were no compatibility problems, off with the back and straight in.

Charging takes about 50% ish longer than the standard battery but that isn't a problem for me. I carry a spare charger around so it will get a top up when the phone is showing less than 5%.

As expected it has extended the standby of my phone considerably. I can get the best part of two days now where I was struggling with one day practical use with the standard battery. It does alter the feel of the handset adding some bulk and weight to an almost impossibly thin design. But IMHO this has improved matters considerably.

Anybody with a Galaxy S3/S3 LTE would be well advised to buy one of these. It is cheaper than the original battery elsewhere, 100% compatible and won't bend the inner right battery terminal like that blasted 'Zero Lemon' attempt did.

Utterly Recommended!

I love charging my phone mid-day!

Said no one, ever.

Had this about a month now, and it's a masssive improvement. I bought this because I started getting fed up with battery levels by about 2pm and topping it up mid-day. After much sitting on the fence, I bought this. It's worth the money! I now charge my phone in the evening and don't worry about it again until the next evening. Chuck power saving on and it'll last two days. Make sure you run it through a few full-cycles to start with and away you go!

Pros:
- Lasts 24 hours
- Big improvement on the standard battery
- GIves the S3 a more solid feel in your hand, making it actually easier to hold
- Only adds a few extra mm of depth to your phone, low profile compared to other battries
- Legit Samsung battery cover provided, easy to install

Cons:
- You can no longer use most standard phone cases, so you'll need to find a bumper case or extended case.
- Takes a bit longer to charge (but you can leave it overnight just fine now!)

I use an aluminium bumper with it, and it's got a great feel. All you need to protect is the corners, so I'd recommend this.

Very happy with this one. A few months down the line I'm still regularly getting home at 6 or 7pm with more than 50% left. I can go out at night with under 30% and be confident it won't clunk out on me.

I love my S3, but I really don't love the battery life. On a good day, with limited use and a bit of battery management, by 8pm I'm nursing the last 15% of power. Tonight, with the extended battery pack on its first full day of use - and after giving the phone a reasonably good work out throughout the day - at 8pm I have more than 50% left. So I'm a happy bunny.

There is a price to pay, however: the phone is noticeably thicker and heavier. But it still slips in my pocket comfortably and is very far from being a brick, so for me a very reasonable trade off. The other issue to be aware of is the lack of case options. None of my cases fit (yes, sadly I have quite a few), there's nothing on Amazon I can find, and the only thing I have been able to find to provide some protection is a black plastic bumper case, from which the (new) back protrudes and is so prone to scratches.

Basically, this is the battery the phone should have come with. So far it seems you can surf, listen to music, access a few apps - and even make calls (odd behaviour for a smart phone, I know) - and still have power left at bed time. So if you're sick of trying to find somewhere to top up the power halfway through the day, this may be what you're looking for too.

Excellent purchase if you don't mind the extra thickness required to house the additional capacity. I work in a big building filled with smartphone users, right next to one of inner London railway stations, so my phone seems to need to use a lot of power to maintain data connection. So during the week, with the stock battery, my phone would be dead at around 4pm, with low to moderate usage.
At the weekend, in a much less densely populated area and under home wifi coverage, it would make it through the day but not much more. Note that we're talking about a battery that's been charged daily, sometimes more, for a year and a half so a new battery probably would last longer.

On the 1st day With the extended battery, it lasted from 6:30 till midnight with untypically high usage.
At the weekend with light use, the battery got below 10% after 1day and 9hours ! I put it to charge after that and it got to 90% charge after 2hours, so not bad at all.

So it's a huge improvement over the stock battery, well worth the price of the extra thickness. It will make getting a case that fits a lot harder though. In my case I'll have to find a new 'universal' car holder as the one I have is specific to the S3's standard thickness
