Key Takeaways -

  • iPhone 17 starts at $799 with 256GB storage and a 120Hz ProMotion display.

  • iPhone 18 may feature an A20 chip based on 2nm technology and more RAM.

  • The standard iPhone 18 could arrive in spring 2027 instead of late 2026.

The Apple iPhone 17 has already made a strong mark in the smartphone market, while the iPhone 18 remains on the horizon. Apple has not announced the iPhone 18 yet, so several details about the next model come from current reports and leaks. The biggest surprise this year does not concern a new chip or camera. Apple may change its usual launch plan and bring the standard iPhone 18 in spring 2027.

iPhone 17 Sets a High Standard

Apple launched the iPhone 17 in September 2025 with a starting price of $799 in the US. The base model now offers 256GB of storage, which gives buyers twice the entry storage of the earlier 128GB option. Apple also added ProMotion to the standard iPhone 17, a feature that once helped separate Pro models from regular models.

The iPhone 17 has a 6.3-inch OLED display with a refresh rate of up to 120Hz. The screen can reach 3,000 nits of outdoor peak brightness. The phone also has an always-on display and Ceramic Shield 2. These figures place the standard iPhone 17 much closer to Apple's Pro range than earlier base models.

A19 Chip Gives the iPhone 17 Strong Power

Powered by Apple's A19 processor with third-generation 3nm technology, the iPhone 17's six-core CPU is claimed by the company to be 1.5 times more powerful than the A15 chip used in iPhone 13. Furthermore, the iPhone 17's five-core GPU boasts more than twice the ability of its A15 processor counterpart. 

Another highlight of the device is its battery life which has improved significantly as well. The maximum video playback time provided by the iPhone 17 is rated to be 30 hours, which is eight more than the same metric of the previous generation. All in all, the combination of the new chip and a 120Hz display makes the new device a really tough competitor in the luxury smartphone sector.

Camera Hardware Gets a Major Upgrade

The iPhone 17 carries a 48MP Fusion Main camera and a 48MP Fusion Ultra Wide camera. The front camera uses an 18MP Center Stage system. This setup gives the standard iPhone 17 a much stronger camera package than earlier base models.

The iPhone 18 may bring further camera improvements, but current reports do not provide a final specification list. Some major camera reports focus on the iPhone 18 Pro rather than the standard iPhone 18. Features such as a variable-aperture camera should not appear as confirmed iPhone 18 specifications at this stage.

iPhone 18 May Bring the A20 Chip

The expected iPhone 18 could use Apple's A20 chip, with reports pointing toward a 2nm manufacturing process. A smaller process could help Apple improve power efficiency and performance. Reports also suggest more RAM, with figures from 9GB to 12GB appearing in current leaks. The exact RAM capacity remains unclear.

The chip could also support stronger on-device artificial intelligence features. Apple has placed greater focus on AI across its latest devices, so a new chip may give the iPhone 18 more room for advanced local processing.

Biggest Change Could Be the Launch Date

Apple may break its familiar yearly schedule with the standard iPhone 18. Current reports place the standard model in spring 2027. Apple may release the iPhone 18 Pro and iPhone 18 Pro Max in the second half of 2026, while a rumored foldable iPhone could also arrive in that period.

This plan would give the iPhone 17 a longer period as Apple's main standard iPhone. A gap of roughly 18 months between the iPhone 17 and standard iPhone 18 would also give buyers more time to consider the current model before the next standard version arrives.

iPhone 17 Sales Show Strong Demand

The iPhone 17 has already produced strong sales numbers. Counterpoint Research data showed the iPhone 17 as the world's best-selling smartphone in the first quarter of 2026, with a 6% share of global smartphone unit sales. The iPhone 17 Pro Max ranked second, while the iPhone 17 Pro ranked third.

Apple also reported $111.2 billion in total revenue for fiscal second-quarter 2026, a 17% year-over-year increase. The company said iPhone revenue reached a March-quarter record, with strong demand for the iPhone 17 family. Sales also showed double-digit year-over-year growth in China and the US, while South Korean sales reportedly tripled year over year.

Price Could Become a Key Difference

Apple has confirmed the iPhone 17 at $799 in the US, but the company has not announced a price for the iPhone 18. Current reports point to higher memory and storage costs across the industry, which could put pressure on Apple's pricing plans.

Some analysts have even discussed a possible $200 increase for certain iPhone 18 models. That figure remains an estimate and should not serve as a confirmed price. A final iPhone 18 price will only become clear after Apple's official announcement.

iPhone 17 or Wait for iPhone 18?

The iPhone 17 features the 120Hz ProMotion screen, 256GB of storage, 48 megapixels main camera, 48 megapixels ultrawide camera, 18 megapixels front camera, 30 hours of video playback capability, and A19 chipset, making it amazing.

The iPhone 18 may introduce A20 chipset, a potentially newer 2nm chip fabrication, more RAM, improved cameras, and other exciting features, but none of them have been confirmed yet. Experts seem to expect change in the schedule instead of any spectacular design changes.

The iPhone 17 is superior at the moment, as its specifications are already known and the price is $799. The iPhone 18, however, is anticipated to have better specs, even if not much is known about its price and release date yet.
