1 YEAR 1 MONTH UPDATE: Like a beast it is still rocking. Charge times have not changed. Battery time is still the same. I am really amazed. And having modified the Otterbox to fit it I am really quite content. I cannot compare to any other batteries in this size as I have no need since this has done it's job for the last year without pause.

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.

Color: black
My husband is willing to try anything once, especially when it comes to his phone. I will spare the details, but he is no stranger to pushing his phone to the max. So when he saw this ZeroLemon 7000 mah battery for his Galaxy S3 on Amazon, he was all for it.

He realized going in for a battery this size, there would be some size to it and his normal case would never fit, but it did come with a soft plastic back for the phone. When it arrived he was amazed that it was more like a really large size battery piggy backed on a normal battery. The case fit on super easy and is a soft plastic which adds much more grip than the stock shiny plastic back that came stock from Samsung. It looks like it will absorb a fall, but as to how long the case lasts is an unknown. By the way, he is not adventurous enough to actually drop the S3 to test the back's protection.

So he got it all charged and ran it for 24 hours under normal use, including some WiFi tethering and music streaming. Really a normal day for him. There was still 48% of the battery left after 24 hours. For an S3, that is amazing. Yes, he said it adds some weight and thickness to the phone, but it still fits in his car holder and he just carries it in his pants pocket so it fits fine.

So now he is totally in love with this battery and singing its praises. Then he took a little trip and clicked on the GPS for navigation. Hmmm, no satellite lock! Well, S3's are notoriously known for bad for GPS, but he has always been able to get a lock outside. He went through possible fixes on line and tightened all the screws, pulled the SIM card yada..yada..yada, but still no satellite lock. He was not even thinking it was a battery issue until he thought about the size of the battery.

-------------- Update 8/2014 -----------------

The battery is still holding a charge and works properly. However the battery has started to bulge in between the two of the cells. It appears as a small separation and TPU case becomes very tight because of the bulge. No odd or extra heat being given off during charging or use.

----------------------------------------------

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