Just a few standard Phillips screws stand between us and the good stuff. Our Marlin driver set has us covered, but we're glad that Samsung only has us using one driver for now.

These midframe assemblies with their integrated coils have learned a new trick: they can now wirelessly charge other devices.

That's probably why the coils are sandwiched between two layers of graphite this year—a wireless charger that transmits as well as receives will produce a lot more heat.

Wireless charging is inherently inefficient, generating loads of waste heat as a byproduct.

The verdict is still out on how much this might affect the long-term battery life of the phone doing the charging—especially on a battery that's not easily user-replaceable.
