We told you not to buy the 16GB iPhone 6s or iPhone 6s Plus, and here’s another reason why you should avoid that smartphone: by default, the photos you snap will take up twice the space as they do on older iPhones. That’s because of a new feature called “Live Photos.”

Live Photos, which is on by default but can be turned off, records 1.5 seconds of content (several JPEGs) at each end of the photo you snap. It allows for a unique and very “alive” effect when you tap a photo in the gallery to preview it, but it’s also going to consume up twice the space as a normal photo, according to TechCrunch. That’s going to eat up space if you’re a frequent photographer — space that’s already going to be limited due to the increasing size of applications and games that will take advantage of the new and more powerful A9 processor.

Again, you can turn this feature off, but if you’re buying a new iPhone, the whole point is probably to take advantage of all of the features it offers. And you’re going to want to make sure you have enough space to actually use Live Photos, since they seem pretty cool.
