[Galaxy S6 Accessories] gsrrr:
I received mine last week.

Packaging - Item was nicely packaged inside a resealable zip-lock bag. Inside the bag, the item is inside a smaller cardboard box along with installation instructions, warranty card information, the phone case that holds your phone along with the battery and battery connector, the (HUGE) battery, and an extra battery connector.

Case – This was my first silicone case with this phone. I usually stick to TPU as silicone cases pick up/attracts dust. Time will tell how it will hold up. The power button is easy to push and the cutouts are all in the correct places. There is a cutout in the back for the camera/flash as well as the battery LED status lights at the bottom. There are cut cutouts on the right for charging (charge your battery/phone and also charge other devices!). There are also speaker, microphone, & headphone cutouts at the bottom as well as cutouts at the top for the IR blaster and microphone.

Installation – I took off my daily TPU case and connected my phone to the battery and dropped it into the black silicone case. Unlike the other smaller Zerolemon battery cases, this did not have a super tight death-grip-like fit. The other case with the smaller battery and TPU case and a super tight fit that was difficult to put on and take off. It would also press up against the side of my glass screen protector causing it to lift off the phone screen. This case fit nicely and did not have any issues.

Usage – To charge the battery, just plug in a micro usb cable into the battery and plug the wire into a wall wart. The white LEDs in the back will light up indicating the level of charge left in the battery and will also blink the last LED to show that it is charging. When all four LEDs are on and the blinking stops, the battery is full. To check the battery level when your phone is connected, just press the back button once and the LED light up for a few seconds to display the approximate charge of the battery (each light ~ 25%). To turn on the battery to charge the phone, you press and hold the back button and the LED will turn and stay up to show that the battery is on and providing battery to recharge your phone. To turn the battery off, press and hold the button again until the LED lights turn off.

Two complains I had with the other smaller battery case were that: 1) there was no pass-through so your computer does not see your phone when you connect the battery case to your computer, and 2) your phone would not receive quick charge when connected to a wall wort while it was in the battery case. This new version addresses both issues, the computer can connect to your phone through the case so your files are accessible, and quick charge works through the battery case (to charge the phone, the battery does not accept quick charging). Another new feature is an USB port at the top which allows you to connect and charge other devices. This is a big plus since this battery is so large (stock S6 is 2550mAh and this beast of a battery is 8500mAh).

Thoughts - If you did not noticed from the photos and dimensions listed, this thing is gigantic. At 8.47 oz, its weight is almost double that of the phone itself (4.87 oz). The battery alone stands taller and wider than the phone. Add a phone case to wrap it all up and for protection, you have a large brick in your hand. But I knew about the size before I received the item. One issue I found was that the battery does not turn off automatically after it fully charges your phone. Not a big deal as this is not the type of battery you leave on to charge your phone overnight. This would be a case to use if I knew I would not be near a charging station that day for a long period of time. I was glad to have this battery case as my phone was over 2 years old and the battery life has been going down hill.
