Don't Buy a 16GB iPhone 6
When Apple sold the iPhone 6 it sold it in 16, 64 and 128GB sizes. Apple no longer sells the iPhone 6, but you can find one through third-party retailers like Amazon and eBay.
Buying a cheap, 16GB iPhone 6 might seem like a deal, but you're better off going with a 64 or 128GB model. Here's why.
Apple's software advancements have taken some of the pressure off the iPhone's internal storage, but 16GB simply isn't going to be enough for most people.
Apps, particularly games, can take up a huge chunk of storage. Messages can take up hundreds of megabytes or several GB if you save them for longer than 30 days. Photos, videos, and music can and will take up a ton of storage space as well. Some of you will reach the 16GB threshold in a matter of days.
There's a reason Apple dropped 16GB iPhones from its lineup. It's no longer enough storage for average smartphone users.
If you can, avoid the 16GB iPhone 6.
