Will the iPhone 6 be the major upgrade Apple fans are looking for or will it be a huge disappointment? Of course that depends entirely on the features it ends up having, and the speculations have ranged from something as basic as a faster processor to a major camera upgrade or fingerprint authentication.

iPhone 6 5s

Today we have speculations on both sides of the continuum, with supposed leaks point to a major upgrade for the iPhone 6 and other more ho-hum views regarding expectations for iPhone upgrades before the end of the year.

iPhone 6 rumored to have upgraded specs

Let’s start with the new allegedly leaked photos. They come from C Technology, a user of Weibo, and were spotted by BGR. The photos have been linked with the iPhone 5S moniker, but if these upgrades are indeed real, there’s a chance they could be big enough to be for the iPhone 6. One place they don’t match up though is in the screen size of the device. Earlier this week there were reports that the next iPhone was being delayed because of the addition of a slightly larger 4.3-inch screen.

This latest report indicates a 4-inch IGZO display which will have the same resolution as the iPhone 5. Also an A6 processor is expected along with quad-core SGX 554MP4 graphics, 2 GB of RAM and a new LTE radio, which would make sense since the new iTunes Radio service is expected to be coming soon. There’s also said to be a better 12-megapixel camera, a dual LED flash, near field communication (NFC) and a fingerprint scanner. Earlier this week there were reports that there would be early supply issues with the next iPhone because of problems with the fingerprint sensor, so today’s report does match up with that in terms of hardware.

Wall Street expects another slow upgrade year for smartphones

If the iPhone 6 or iPhone 5S as so many are coming to expect this year, does have these features, would it be enough to make Apple Inc. (NASDAQ:AAPL) users upgrade their devices? The Wall Street Journal’s Spencer E. Ante reported this week that smartphone users are upgrading their devices at a slower rate than they were in previous years, likely because the upgrades just haven’t been that much.

Samsung’s Galaxy S4 sales have been tepid this year, so Apple Inc. (NASDAQ:AAPL) investors are likely expecting the same results from the iPhone 6 or 5S, whichever comes out this year. It will ultimately depend on what kinds of upgrades are offered and whether they make it worth the effort and money to upgrade.
