Hello！
The speaker of the blog is NeYhaaa
Recently, questions about data troubles and data have increased
iPhone5s and 6 seem to feel a burden on ios11
If you have data that you can organize, let’s increase the iPhone’s capacity even a little
〈 Capacity 
Available capacity 
Actual storage capacity 〉
16GB 12GB around 7GB
32GB 25GB around 20GB
64GB 56GB around 50GB
128GB 120GB around 114GB
256GB 247GB around 240GB
By subtracting the operating capacity of 5 to 10 GB from the above。。。
I would like to post a method of widening the storage for a while (＾_＾)
Thank you for happyfield always
