Product Description

Use your phone like you should - without worrying about running out of battery.

3.4 times of your battery life.
Packed with 7200mAh of pure power, use your phone a full three times longer than you previously could. That's up to 70 hours of talk time or 25 hours of internet time. Stop worrying about your battery life and enjoy your phone even more.

Keep your S3 newer, longer.
The flexible TPU back cover we've included covers your phone's four corners, effectively absorbing bumps and impacts, all while only adding about 0.4 inches of thickness (including battery) to your phone. Improve both your battery life and your phone's life at the same time.

Use 100% of the stored power.
The unified battery design completely eliminates voltage conversion waste (20-35%) giving your phone 100% of the stored energy to use. Also, lacking the complicating external wires, power buttons and power meter LEDs, of external batteries and many battery cases, enjoy using your phone without the added complexity.

Upgrade via replacement.
We wouldn't give you anything less than the best. Grade A cells chosen from among the top 10%. Rigorous inspection tests to ensure reliability. A built-in IC chip to prevent against short-circuiting. What does this all mean? In terms of quality, you won't find a better replacement.

For optimal use.
To correctly install, first, slide the battery into the phone's battery slot, and then install the case.

Get to know us.
We created Anker with a single goal in mind: to make the smart life easier. That means starting with affordable, high-quality gear and ending with a commitment to 100% user satisfaction and an 18-month warranty. After all, we're customers too.

5.0 out of 5 stars Excellent battery for certain scenarios 24 Jan. 2014
This is the second Anker battery I have -- the first one is for my earlier Galaxy S, which I bought following enthusiastic recommendations from a close friend. The quality of the batteries is consistently exceptionally high. Even the packaging and leaflets are comparable to that my S3 came in. Those people really try to distance themselves from cheap imports.

The battery runs forever on a single charge. With the original battery my phone typically always consumed around 20% overnight. With this one, it's 5%. Obviously, not much happens when I am asleep but this is useful for comparison, precisely because the consumption pattern is relatively the same.

It is considerably bulkier and heavier than the standard battery, but this is not surprising considering this is really like three batteries put together + a thick back cover replacement. This means the phone won't fit in most cases. If you open the packaging and you wonder like I did, you can actually remove the new battery from the rubbery back cover, and insert it into the phone first. The back cover replaces the phone's back cover and also acts as a protector, similar to other rubbery cases, only this one is more heavy-duty and thicker than usual.

I wouldn't personally use this every day because I can recharge at work etc. But this is brilliant for people who frequently spend long periods away from power supply and/or want to have many things switched on. For example, you can cycle in the middle of nowhere with GPS, maps, media player, internet browsing and possibly a training app running without worrying too much. It is also reassuring to know you have this battery with you just in case your slimline battery runs out.

4.0 out of 5 stars Does the job when travelling 8 April 2014
By Buck R
Verified Purchase
I bought this to use when travelling. Because I can put my phone in my laptop bag it is no problem.
BUT - I would not like to use this extended battery for day to day use. It makes the phone (Galaxy S3) very heavy and bulky and not very comfortable in a pocket.
On reflection I would probably have gone for the smaller (4400mah) battery.

Edit - Anker (Sunnie) have been in touch and provided me with the 4400ma version.
This is a much better weight/size and fits nicely into a pocket. Great service.

1.0 out of 5 stars good performance within the first 8 weeks 6 Feb. 2015
Verified Purchase
Faulty battery, not fit for purpose, good performance within the first 8 weeks, since then it has repeatedly failed, randomly shut down, and affects the overall speed and performance of the Samsung S3 handset.
Installed on 4th September, given a full charge as per instructions with recommended charger, and charged once or twice a week when power reading was low.
Over the last 2 months, after a full charge, I am lucky to get 6 hours of daily use out of the battery - I am a low user of the phone, just checking emails & the occasional text & calls, rarely if ever, do I play a video or audio file.
What is more annoying than the battery not holding a charge for long periods, is the frequent & random power cycling, and sometimes shutting down completely.
This occurs whether or not the handset is "mobile", i.e. it happens whilst on my desk, shelf, wherever...
Not happy with it, for an expensive product of £30 I expect reliability and for it to last more than 4months !!
As a test I have replaced it with a colleagues spare Samsung S3 standard battery ( 2100mAh/3.8volts), it has not failed within the last week and the lifespan before a full charge is 2-3 days, pretty good for an "old" battery & much better than the Anker 7200mAh.
My advice - on paper the Anker 7200mAh sounds good, in practice it's a waste of money and time.

5.0 out of 5 stars “It does exactly what it says on the tin” 27 Jan. 2014
I don’t know about you, but I sometimes struggle to get a full days use from my Galaxy S3 before the battery needs to be recharged. If you experience the same issue, or have to restrict using power hungry apps / phone features just to ensure your battery doesn’t die, then this offering from Anker might be just what you are after. The high capacity extended battery case replaces the standard battery and flimsy back cover with a 7200mAh li-ion battery and flexible black TPU back case, which provides almost 3½ times the life of a standard battery. Now of course you’re not going to get all this extra capacity without a compromise, so it shouldn’t come as a shock to anyone that this extended battery combo will increase the size and weight of your phone.

To help illustrate, my S3 with the standard battery and back cover weighs in at 131g, but with this product weight increases to 281g. The new back cover is necessary because the extended battery is significantly larger so the original back cover won’t fit. However, it is made from TPU with matt sides and a high gloss back (which unfortunately does show up fingerprints rather well). The case fitted perfectly – the buttons worked absolutely fine, there were holes in all of the right places including a recessed cut-out for the speaker, camera and flash (crucially, this doesn’t interfere with taking shots unlike on some other cases which cause flash bleed). The case wraps around the edges of the phone offering a little extra protection from bumps and knocks, although I decided not to perform a drop test for this review, hope you don’t mind! I did however measure the phone and new cover – it is slightly wider and taller at approx. 74mm x 140mm, and quite a bit deeper at 19mm due to the thicker battery and wrap-around style cover.
