YESOO Extended Battery (4300mAh), Cover, TPU Case For Samsung Galaxy S3 III GT-I9300 + Exclusive Black And Green Color Key Chain Kit (Black Cover, Black TPU)

Can I start off with, it got boring trying to find ways to drain my battery so I can charge it for the first couple of times? I watched youtube all night and didn't charge my phone. I woke up and still had 1/4 battery life... I had to watch more Youtube videos in the morning before I finally got redlined. This battery lasts forever. The only cons are the charge takes a lot longer then normal seeing there's more to charge :) It's also a big battery so the phone becomes larger. The case it comes with feels great in your hands so it makes up for the largeness of the battery.Overall love the case/battery. Don't forget the super low price!! :)

Makes my galaxy s3 feel like a new phone. Last longer than a day and a half. I'm a heavy user, internet and Facebook. I recommend this battery to anyone who wants to go all day on a single charge. 4 stars because the battery is not NFC ready, but that's a small thing. I barely used that feature anyways. The back case and sleeve make the phone feel good in your hands

Definitely added extra life to my phone however I don't feel that I was getting anywhere near the extra capacity I should have. I followed all the charging instructions but I didn't get any great results. For the extra bulk that's added from this battery I think I would have just gone with a smaller size/capacity battery.

Battery is okay but extremely large just like it post. Case is horrible I removed galaxy S3 from an otter box case and as soon as I put the phone in the new case it broke. Same day. Company is very well about customer service I would order from them again just not this product

i wish the rubberized cover could be replaced by a otter box however i can't find a otter box for the extended battery.

I bought this battery to extend the length of time between charges, thinking it would give me a longer run time then I have with the stock battery. Usually around six PM everyday I have to charge my phone with the stock battery.Fully charged this new battery does not last as long as my stock battery that is three years old. Also the phone has to be turned off to charge. I would not recommend this product to anyone.

I have purchased thousands of items from Amazon and I can easily say the is the absolute best value I have ever received. My phone was going dead daily due to a poor signal in my office building. I now have at least 30% left at bedtime. This thing does what it does very well. The case is perfect too. You will not be disappointed.

The standard battery for my phone only lasted till noon or on a great day till 2:00 PM. This battery lasts all day and most of the next day. Instead of charging 2 or more times per day I charge every other day. It doubles the thickness of the phone but still fits comfortably in my belt clip holster for my Galaxy S3.
