16GB is not enough for me but 32 was just right. Unfortunately, they don't have 32 anymore so I settled for 64 and that's plenty for me. How much space do you have and how much are you using on your current phone?
I had the 5s with 32gb and with no music had to delete from phone (had copies on laptop) 1,000 pictures. On the 128gb 6ss I have 4,957, no music (YET) and still have 109gb available. Since my old Nano only has 597 songs, I am sure I will not run out of space on the new phone.
I had 16gb and that is nothing, because i love to make videos, so i thought 128gb would be right, but after a little research i found out with 64gb would be ok and this is the kind of videos i record on my iphone:
I went with the 128gb 6s Plus, a serious upgrade from my 32gb 5s. I realized that it wasn't necessarily the info I would accumulate over the next one/two years, but the info I already have plus the info I will gain in the year(s) to come. I like everything on my device so I have it when needed and don't have to worry about cloud storage and transfer....That's just ME, and this works for ME
I just bought a 128GB 6s. I previously had a 64GB 6plus. That was plenty for typical use, but I want to put my complete music library on my phone. I get tired of syncing to swap out songs and I don't care for iTunes Match as it would still require cell data use.
I do have a question though. Have any of you noticed any issues once you have used more than 80-90% of your capacity? I don't want to load up my phone only to find out that it will run slower. I've been using MS Windows since it came out, so you might understand why I would ask such a question lol.
You do need some free space for things like temporary files while browsing and accumulated data while using apps and games, for example. If you leave too little storage space on your iPhone it will affect performance.
Even updating the iOS version on your iPhone requires the temporary use of up to a gigabyte or more of storage space to download and process the update when updating OTA.
