A new document leaked by a supposed Foxconn employee, the company that builds the iPhone in China, was obtained by Apple Insider, and it reinforces rumors that the iPhone 6's successor could have a 12-megapixel camera, as well as 2 gigabytes of RAM.

A new, higher-resolution camera may result in photos with even clearer, crisper detail, but megapixels aren't everything when it comes to cameras.

Rather, a 12-megapixel camera compared with the iPhone 6's 8-megapixel shooter would allow you to record slow-motion videos in ultra-high 4K resolution. 4K resolution means video shot with the next iPhone will be about twice as sharp as video shot with the iPhone 6.

The iPhone 6 and 6 Plus both have 1 GB of RAM, which is your iPhone's short-term memory that lets you bring up recently used apps very quickly. There haven't been many complaints about the iPhone 6's performance, but Apple could just be trying to future-proof the phone for software advancements in coming months and years.

More RAM would let your iPhone store more-often-used apps in the background for you to reopen very quickly. But it could also have a small negative effect on battery life — and on the next iPhone's price tag.

Still, these are just rumors, and Apple Insider also makes a point to mention that the source isn't proven. The alleged leak does, however, back up previous rumors about the next iPhone. In fact, there were rumors as early as last fall saying the next iPhone would get a camera rivaling some "regular" digital cameras.

Other leaks of the purported iPhone 6S' design have appeared online, and there has also been mention of potentially faster 4G LTE performance, as well as better battery life.
