In line with the rumors ahead of Apple's (NASDAQ:AAPL) event on Monday, the tech giant announced a new, lower-cost iPhone called iPhone SE. Replacing the iPhone 5s, the phone beefs up the company's offering at lower prices, giving Apple a more appealing product for customers looking to spend less for their new iPhone.

It might be both smaller and lower-cost than the flagship iPhone lineup, but that doesn't mean the device won't move the needle for Apple. Further, the company's move to offer a lower-cost iPhone may provide a glimpse into a maturing smartphone market.

Before we dive into some of the implications for Apple's business, here's a quick overview of key details about the new phone:

  • Price: With a starting price of $399, the phone costs $250 less than the starting price of the flagship iPhone 6s.
  • Design: Apple's new iPhone SE has essentially the same 4-inch form factor as the iPhone 5s it has replaced.
  • "To create it, we started with a beloved design, then reinvented it from the inside out," Apple says about the phone on its website. 
  • Battery: One strong point about the new device is its battery life. Apple asserts the phone has up to 13 hours  of battery life while using LTE Internet. This is 30% more than the battery life of the iPhone 6s.
  • Camera: The phone's camera is also significantly better than that of the iPhone 5s. Indeed, the iPhone SE's rear-facing iSight camera is the same 12-megapixel camera used in the iPhone 6s.
  • CPU and GPU: The phone's A9 chip and M9 motion co-processer doubles the CPU performance of the iPhone 5s. Its GPU performance is three times faster than the iPhone 5s.

Why it matters
The upgrade makes sense. During Apple's most recent earnings call, CEO Tim Cook specifically noted that the iPhone 5s continued to sell well for the company -- even though it has introduced two generations of new flagship phones since the device's release. Further, a growing portion of Apple's sales are coming from emerging markets like China and India, where it's more difficult to afford an iPhone.

The iPhone SE is being launched about halfway between the company's usual September iPhone announcements, highlighting Apple's eagerness to do whatever it can to boost iPhone sales. During Apple's most recent quarter, iPhone sales growth slowed down significantly to 1% year-over-year in iPhone revenue and nearly zero growth in iPhone unit sales. And for Apple's current quarter, the company actually guided for about an 11% year-over-year decline in total revenue because it expects iPhone sales during the quarter to be lower than in the year-ago period.

While the launch of Apple's iPhone SE could help moderate -- or even prevent -- year-over-year declines in iPhone sales in the second half of the year, the phone does raise some concern about increasing competition. The tech giant's need to give its 2-year-old iPhone such a significant upgrade without increasing its price could be a sign that it's getting more difficult for Apple to attract new customers in a maturing smartphone market.

That said, Apple's ability to seriously upgrade its 2-year-old iPhone could also be a sign of the tech giant's enormous scale and increasing prowess in mobile processing power.

Whatever the reason Apple chose to introduce the iPhone SE mid-cycle, investors shouldn't fret: Increasing competition is already priced into Apple's wildly cheap valuation. The stock trades at just 11 times earnings.
