The Galaxy S6 comes with an unremovable 2,550mAh battery pack. It features integrated wireless charging for both WPC and PMA standards, which means it will work with almost any charging pad you lay it on.
Samsung also equipped the Galaxy S6 with the Note 4's quick-charging technology, so you should be able to charge it up in 10 minutes with enough juice to last you through a two-hour flight.
What about LoopPay?
Samsung's Galaxy S6 has LoopPay's Magnetic Secure Transmission (MST) technology embedded inside, in addition to NFC. You can also use your fingerprint to authorize payment by holding down on the Home button. However, this technology won't be available to use until summertime.
And what about that curved phone?
The Galaxy S6 Edge.
The Galaxy S6 Edge is curved on either edge and, thankfully, doesn't employ the same standalone dock interface as the Note Edge. Instead, it has a neat feature that lets you choose from one of eight colors to quickly glance at who's calling you when the phone is placed upside down.
The Galaxy S6 Edge is packed with all the same components inside as its flat cousin, except for a larger 2,600mAh battery pack.
A few more things
The Galaxy S6 comes preloaded with OneDrive.
Because it's all metal and glass, the Galaxy S6 isn't waterproof, so don't plan to bring it with you into the pool. Also, it no longer features expandable storage. Instead, Samsung will sell its flagship device in 32GB, 64GB, and 128GB variants. And if you need more space, you can take advantage of 65GB of free space offered by Microsoft OneDrive.
Samsung's also releasing an updated version of its Gear VR virtual reality headset that supports the Galaxy S6 and S6 Edge.
