The battery life is so much better.
R. Jaraiedi
It does make your phone a brick (thick and heavy), but it feels solid in hand and the TPU soft plastic case fits well and provides good protection.
R.S.
Overall, I get 2 Days and 3 hours of battery life out of it without a charge with heavy usage.

UPDATE ON BATTERY TIME: Using the phone on the lowest brightness I got 117.5 hours = 4 days 19 hours of runtime. Using the phone at the brightest screen setting I got 64.5 hours = 2 days and 16 hours of runtime. Charging from 0% took 12 hours but I found a glitch, it will say 100% at 6 hours, but when you unplug it, it drops down to 60% or so. Plug it back in and charge it to 100% in another 6 hours. This battery truly does rock.

UPDATE ON SIGNAL STRENGTH: I decided to try the free apps. After testing I may need to try the paid apps or just call it quits on testing. I used 2 apps. Cell Signal Strength and Network Signal Strength. I turned WiFi off. I restarted the phone so nothing but the DBM apps were running. I used the ZeroLemon and the Samsung battery included with the phone. Guess what folks? Both batteries returned the same results no matter in the 3 places I stood. This was the highest score GSM STR: 22 LTE RSRP: 99DBM They fluctuated but mostly came back to these numbers. This is why I may need to try the paid apps. I still honestly think that signal strength in Arizona is the issue and not the battery. I just don't know. I get calls and internet almost everywhere it just slows down dramatically indoors. Sorry for the inconclusive results.

UPDATE ON CASE MOD: Used a dremel on the OTTERBOX DEFENDER inner plastic case, cut out the size of the battery. Fits perfectly with the silicon skin to hold it all together (really fits perfectly) and I still have the corners of the phone protected by the case. I am really glad I altered the DEFENDER case to fit this battery. Like walking around with a brick now. And looking at it you can't really tell that it holds this monster battery. If you own the DEFENDER, do yourself a favor and mod it. You will not regret it.

I currently have three batteries for my Samsung Galaxy S3; 2100mAh (stock), 3000mAh (Digital Energy), and this one... the big boy 7000mHa battery.

I was concerned about the TPU surround case frankly, but it worked perfect and in fact better than other cases. For a size comparison, this 7000mHa case size is almost identical to my Digital Energy 3000mAh battery + larger door. So really, why bother with the 3000mAh unless you really want a "stock" look to your phone. There isn't a reason. Here are your pros and cons:

Pros:
** Days of power rather than hours.
** The battery and case fit really well.
** Not any thicker than a 3000mHa kit from Digital Energy.
** Ship time was 3 days.

Cons:
** You need to grab an external charger. Charge time takes a while.
** If you are worried about the added weight, then this isn't for you.
** Recommend 5 charge / discharge cycles. This is a 2 month job because of capacity.

Capacity is a double-edged sword. You will have a ton of runtime, but you will also have a ton of charge time. Just the way it goes. But at $35, and considering that it doesn't make the phone bigger than 3000mHa kits, this is a no-brainer. Easily the best extended battery kit out there for the s3. Do yourself a favor and pick up one of those cheap-o external chargers. Even though they are slow, it ends up saving you time.

If you're like most Samsung Galaxy S3 owners, you're probably getting 8-10 hours of battery life with the stock battery. I ran out of juice several times since purchasing my S3 in Nov '12. I shopped around for weeks trying to find the best battery solution and decided on the ZeroLemon after reading the reviews. I'm glad I did.

I received the battery earlier this week and let it charge for 12 hours as recommended by the instructions. I turned on WiFi, BlueTooth, Location Services (GPS) and set my screen brightness to maximum. I also turned off battery save mode. Here's how my first battery discharge went:

1. 24 hours - 63% battery available
2. 48 hours - 33% battery available
3. 55 hours - battery drained

I should note that I used Pandora, video recording and a fair bit of camera usage - especially on the third day.

Likes:
- Blue case looks great
- Feel and grip of the case
- Excellent workmanship and fit of the case - all the holes line up nicely and I had no problems plugging in the power cord or headphones
- Very long battery life
- Ability to keep brightness at maximum without worrying I'll be out of juice by the end of the day

Issues:
- No issues with the battery or the case but I did find out some things about the S3 when the battery gets low
- When the S3 battery reaches 10%, features like the camera stop working
- When the battery reaches 5%, the screen dims and can't be turned up

If you want a bigger battery for your S3, I recommend this one.

As I type this I'm trying like hell to kill this battery...I have followed ZeroLemon's recommendation and fully charged it for 12 hours before first use, and during the first five cycles get it down to one percent before charging. I am on my 5th cycle now, and have to use games and the assistive light app to go from 2% down to 1%. ( It's been an hour and twenty minutes with the light on while jumping in and out of several game apps, and I still have 2% ) This thing is a BEAST! I run sync and mobile data only, ( no GPS/Bluetooth/WiFi ) so I cannot attest to performance while using those, but I run Pandora/ Youtube/games/video playback/Gmail/and around 3 hrs of phone use per day, and I get 72 hours of use from ONE charge! With the Samsung stock 2100 mAh battery, I was lucky to get 8 hours at work without plugging it up in the afternoon.... o.O
It does add some bulk, ( about another phone's worth of thickness ) but for this kind of juice, I don't care one bit! The case fits snugly, and cleans up easily. ( I changed out an alternator in a friend's car and the dirt/grease came off with warm water and a washcloth )
Long story long, if you need the uptime, get this battery!
