Apple's second-generation iPhone X and so-called iPhone X Plus could be priced from $899 and $999 respectively in the United States, according to RBC Capital Markets analyst Amit Daryanani.

Daryanani said the current iPhone X has experienced "limited success" at $999 and up, leading him to believe that lowering the base price by $100 could reinvigorate sales of the 5.8-inch model. A widely rumored 6.5-inch model, dubbed iPhone X Plus, would then fill the $999 price point.

While this is merely a prediction from one analyst, the strategy could make sense if iPhone X sales have slowed significantly, as a series of supply chain reports have suggested. We won't know for sure until Apple's next earnings report, likely to be released around late April or early May.

At this point, all we know is that the iPhone X was likely a key contributor to Apple's record-breaking revenue of $88.3 billion last quarter, easily topping its previous all-time high of $78.4 billion set in the year-ago quarter. Whether that momentum carried forward to the current quarter remains to be seen.

Based on Daryanani's research note, obtained by MacRumors, here's our take on how the next iPhone lineup could look in terms of pricing:

6.5-inch second-generation iPhone X Plus: $999



5.8-inch second-generation iPhone X: $899



6.1-inch mid-range iPhone X with LCD: $799



iPhone 8 and iPhone 8 Plus: $549 and $669



iPhone 7 and iPhone 7 Plus: $449 and $569



iPhone SE: $349

Here's a rough idea of how the next iPhone lineup could look if Apple maintains its current pricing strategy instead:

6.5-inch second-generation iPhone X Plus: $1,099



5.8-inch second-generation iPhone X: $999



6.1-inch mid-range iPhone X with LCD: $799



iPhone 8 and iPhone 8 Plus: $549 and $669



iPhone 7 and iPhone 7 Plus: $449 and $569



iPhone SE: $349

Apple will likely unveil its next iPhones in September as usual, and presumably only the company's top executives are privy to pricing plans.
