As we all know though, the amount of storage you actually have access to in the end is smaller than the number on the box. On the 32GB models of the Galaxy S6 and S6 edge — in our case T-Mobile versions — which are the base models of each, you'll find about 23.5GB available on first boot. That's after signing into a Google account and updating all of the pre-installed apps from the Play Store, which presumably anyone who opens up a new Galaxy S6 will do.
23GB free matches what we've seen on the HTC One M9.
Having 23 of 32GB free is about the industry standard, and what we saw on the HTC One M9 as well. If you extrapolate what we see on our own 32GB Galaxy S6, that means you can expect to see about 55GB free on the 64GB model, and 119GB free on the 128GB model. Of course manufacturers always fudge these numbers just a bit considering formatted capacities are different on each storage model — and the software changes depending on the region and carrier will hit that number as well.
It's hard to be upset with those available capacities, particularly with the smaller 16GB model now being off the table completely. Of course this just won't replace the ability to pop in an SDcard for some people out there, but for most it'll be a worthwhile trade off.
