It is working out just great.

In fact, it would get so hot, that it was very almost untouchable.

I've spent a lot of time trying different S3 cases, and this one should be avoided... here are my thoughts on the cases I've tried.

Case 1: CrazyOnDigital Protective Cases for Samsung Galaxy S III S 3 AT&T, T-Mobile, Sprint, Verizon-Black

I wanted to protect my phone so I started out with CrazyOnDigital's case, after a few days I felt that it was too bulky and found it hard to get in and out of my pocket. I also quickly found that the battery in my S3 just didn't last as long as I needed it. After a full day of work and train ride, it was lucky to make it through the commute home.

Case 2: Hyperion Samsung Galaxy S III Battery Boost Case Rechargeable Battery Cover

With the hope of something that was easier to get out of my pocket, and the ability to add some extra battery time, I began a new search and ended up trying the Hyperion case. When I got it, I felt that it wasn't nearly as protective as my first one, but the extra battery functionality worked well(ish) that it made me decide to keep it... I had a few problems where it would get really hot when charging, and sometimes when plugged in it would charge the case's battery but not the phone itself, so I would wake up with a completely empty battery on my phone, but a fully charged case.

On top of these problems, after a few weeks the battery was only adding about 20 minutes to my casual phone usage. I went to return the thing, but Hyperion's awesome customer service contacted me and offered to send me another one instead.

The build quality isn't horrible, and it actually seems pretty nice. the unit charges without issue, and i've done some testing with the signal strength (given the other review i've seen on Amazon) and i could not find ANY drop in signal (EvDO, 3G, or 4G) with the case on. I used the internal signal strength meter on the phone info page.

The BIG issue is when you turn on the charging (from internal battery, not connected to a charger cable). The whole bottom area of the case gets very warm, but the connector itself gets dangerously hot. Too hot to touch.

The minor issue with this case is the side buttons become kind of hard to hit. I'd be willing to let that go if the battery didn't feel like it was going to catch fire after 10 minutes.

It works really well when needing to add a couple of juice to your battery only problem I've notice was that its hard to take off and taking it of a couple of times broke my dis port but if your a person who keeps cases on your phone this is a really good item to have and isn't a waste of money !!

Excited when i ordered this item and extremely disappointed when i received it. Poorly constructed does not cover phone completely. Sides are completely exposed. The battery does not last long and when not in use it drains completely. not worth buying dont waste your money.
