High end phones are already thermally limited much of the time at 27w—I don't have much faith in seeing 100w going into much of anything except large tablets in short bursts in an air conditioned room. The real limit is the internal resistance of the cells. That said, moving more of the voltage regulation out of the phone should help with thermals.
All in all, I like the improved efficiency and thermals, but I don't like dumping a ton of current into a "non"-replaceable battery. I wish these advanced QC5 chargers would come with a "slow charge" mode that limits charge current to 1 or 2 amps to help reduce battery degradation. Better yet, I'd like phones to have user enable-able options to limit charge current(or even charge level).
My last phone's battery lasted 22 months of daily use before degrading to 60% with a 5v/850ma charger. After that I replaced the battery(which required specialty screwdrivers, glue, and a heat-gun to install) and switched to the OEM QC3(12v/1.5a) charger. The replacement battery only lasted 12 months. Maybe the battery wasn't as good as the original(It measured fine when new), but I think the higher current from the quick charger played a big role in the accelerated degradation.
For my new phone I've taken to just charging to 85%. Thankfully, the SD730 is very power efficient.
