Which one? IPhone 6- 64gb or 128gb?

12 albums, 4 social media apps, 10 games( about 1-2gbs each) 6gb for videos and photos.

I think you don't need more than 64gb of storage memory. You phone is still a phone, it is not like a PC that need loads of gigabytes of storage memory.

64gb would be best

Thats nothing, 32 would be fine for you. For videos and photos you can always copy those to pc instead.

The 64GB is probably the best fit, but they're also the hardest to come by at the moment.

16GB just isn't enough with how big some game apps are now, plus photos and videos and music add up if you're not careful.
