Impressive. New updates. Case Mod. Signal strength.
By J. Seidel
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.

UPDATE: Just found out about modding my OTTERBOX DEFENDER to fit this battery. Will do it this week and say if it is worth destroying a OTTERBOX for. I have been dying for a good protective case. The one provided is fine but not drop rated. Glad I got a spare case to play with. Anyways battery still going strong.

Just got it today. Fast ass delivery, thanks Amazon.

Packaging was simplistic and beautiful. Well done zip-lock bag. I like that. This thing is heavy, never forget your phone just on weight alone.

Opened it up, they have directions printed on the battery, at first I thought it was in some sort of plastic shell, realized the whole thing was the battery.
(Damn you Amazon let me post my own pics) Popped out old battery and jacked this one in, was scared to press down on the extended part of the battery but it gave and locked in, tight fit, excellent design.

Snapped the cover on, seems ok. It does bulk up the phone quite a bit and makes you feel like you are carrying a Mid-early 90's Cell phone. Not a bad thing.

Came charged at 53% and in an hour was up to 79%, 10mins later it was at 81%, you do the math. I think that is a great rate for such a battery.

I am thoroughly impressed. Sadly I cannot use my Otterbox Defender obviously. So for long trips this suits me and for reg day stuff I will go back to my Defender/Samsung combo.

Will update on battery life. As time goes on. As of writing 30 mins added 5%

Update 10: Battery still running strong, only one thing has become of any concern and that is loss of signal in buildings. This could be attributed to weather or my provider AT&T. I honestly don't know. It just seems since summer started that I find it harder to get a signal indoors. At home no problem and while driving not an issue but when I enter a building, I tend to get about a 50% chance of connecting. Otherwise I cannot complain about the battery life nor will I. I really like the fact I can run this all day and not have to even think about charging. The back cover has also taken a beating and stays true to form. For the price and the longevity, this battery is a best buy.

Update 9: 6.5 hours till 100% charge. This thing is beast. I will now update monthly. I never seem to run out of power, interesting note: sometimes the battery percentage increases. Strange.

Update 8: Charging now, I will time how long until 100% and both icons appear.

Update 7: 57 hours later and we hit 3%. I say incredible, holy s***. I am constantly on some app doing one thing or another and it lasted this long. Max Screen brightness was about 8 hours.

Update 6: 39 hours without plugging in and it is 30%. Really good!

Update 5: 27 hours no charging. 66% left! Amazing!

Update 4: 17 hours unplugged. Went on the road, phone calls, Google maps, texting, FB, web search, screen brightness maxed. You get the point. 78% BAM! About 7% lost while out for a few hours.

Update 3: Unplugged 14 hours ago. 85% with varying usage. Going on the road for about 2 hours where most of the workload will be done on the phone, we shall see how it puts up with heavy use.

Update 2: According to the phone, battery is fully charged now, both 100% icons show. Might get an App to verify but that is only 6.5 hours to full. Not bad from 53%

Update 1: Approximately 4 hours and it is 100% They say 12 hours to fully charge. My phone has yet to say "Unplug charger" so it is probably still charging. Will update.

Need More Power? This Is Your Best Option!
By Doc1
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.

Much better battery than stock
By JeffD
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.
