I have a 128GB 7 and have only used 40GB and this includes 19GB of photos. It doesn’t off load them unless you need the space which I don’t. I don’t see why I would need more than 64GB especially when iMessage in iCloud becomes a reality.
Looking at my current phone over two years I have used a little over 30 GB. What you guys think? I could maybe pass for 64 GB. I don't know though. Would rather have the space and not need it than need it and run out. A problem with apple and no expandable storage.
