**check comments too please**

I bought all three extended battery brands available on Amazon (Onite 4500mAh Extended Battery, Hyperion Samsung Galaxy SIII 4000mAh Extended Battery), and this one). I then did repeatable battery drain tests using a battery logger application and an app called 'Fast Discharge' (wifi, bluetooth, gps, and cpu enabled. no screen, vibrator, or flash) for all three, and the stock battery...from 100% to 5%.

The Onite battery and the Hyperion both get 5 hours of runtime on the dot, and stock gets 2:45. This battery gets 4:30, and if you watch the video, I show you why. It has physically smaller cells, and there are shims to make up for the space. I peeled back labels on the stock battery, the Onite battery, and the Hyperion battery and NONE of them have shims like this.

QCell is scamming people by using short cells, filling in the space with shims, and advertising it having more capacity than full size cells. QCell isn't sitting on some battery technology nobody else in the world has, and the results prove it.

This product lasts 64% longer than stock, and stock is 2100mAh, so I estimate this battery to have about 3500mAh capacity. This is more than 10% less than the advertised specification. The Qcell battery and the Hyperion battery have the exact same back plate as far as I can tell.

I work from home as an IT manager / Controller and use my cell phone as my office phone. I normally have to plug in right around lunch time, not so with this battery & cover kit. This battery lets me work all day and still have power to spare!

This kit will double the thickness of your S3, but given how skinny the phone is, it is hardly a problem. The included covers fit perfectly. Overall I am very impressed!

I received the battery a week ago, and replaced the OEM battery immediately. With the OEM battery, I frequently received a low-battery warning - usually before 5 PM (after charging overnight). And even when I didn't get a warning, the battery icon was always less than half green by the end of the day. With the QCell battery, the battery icon is always almost-completely-green at the end of the day. Clearly, the battery life is significantly longer.

I have the blue Sprint version of the Galaxy S3, and the blue QCell cover doesn't really match. But honestly, it's not something you really notice. I'd call it a 1/10th point deduction.

When I received the battery it had 55% power remaining on the battery. I drained it to 5% and turned off the phone overnight to give it a full charge. I powered up the phone at 6:30AM.

As of 10:30PM here are the usage stats: Battery life remaining: 25%. Screen "on" time: 5 hours, 42 minutes. I ran the Sirius-XM app for about 60 minutes, downloaded 3 apps, updated 4 apps, played a game for approximately 30 minutes, edited photos for approximately 30 minutes, surfed the web, watched videos for 20 minutes, spent 10 minutes on the phone and sent/received approximately 6 text messages. My phone is set to sync data real-time, and bluetooth was on approximately 7 hours. I run both Yahoo and Gmail email accounts set to provide real time updates. All the data was run via wifi and I have disabled 4g since my area doesn't get the best 4g signal. I run stock android with Apex launcher.

Overall, I am impressed with the battery.

As a side note, I agree with others that prefer the thickness of the phone with the extended battery. I find it far easier to hold, however the added weight will take some getting used to. BTW, The provided battery cover fits very well.

I puchased both the Qcell case and the Yesoo case. Both cases fit the phone, however the glossy Qcell case is a fingerprint magnet. The Yesoo case looks and feels great. It reminds me of the Diztronic matte black case in both style and feel.

Day 2 - It just keeps going and going...

I don't have the specific stats for day 2 because my wife held my phone with the extended battery, liked the feel better and wanted an extended battery and case of her own. I gave her mine.

Since we transferred batteries, I don't have the battery stats for the day.

Item was shipped and received promptly. Packaged well. I have to admit I was skeptical when I first saw this item because of it's low price. A similar well marketed item from a known retailer is priced at more than double this price, but it had good reviews and good mentions in reviews of other similar products. I have been using it for three days now and have been very impressed. I am a heavy user of data; emails, social networking, video streaming, etc. I had 16 hours of use before the battery indicator was red. The battery does add bulk to the Samsung S3, but the benefits outweigh the little increase in phone thickness. I don't worry about my battery consumption at all. Exceptional product.

Update: Battery cover cracked while opening, but the seller sent me replacements for free. Battery has been functioning flawlessly. No complaints. Highly recommended.
