Congrats man... Can you please let us know how does the battery lasts? From what i i know it does say battery is 3100mAh but on the back its also written that usable is a lot less than 3100. Anyhow let us know how much total time you could get without plugging it back in.
Also can you confirm does the backpack charges wirelessly or no.
I had this for one day and took it back for the Samsung fast charge power brick. The case made the phone very warm and just slowed the drain of the phones battery while in use.
