Increased Battery Capacity for iPhone 18 Models
Apple plans to equip the upcoming iPhone 18 and the lower-cost iPhone 18e with a 4,430 mAh battery, according to reports.
This capacity is larger than the iPhone 17's 3,692 mAh battery and the iPhone 17e's 4,005 mAh unit. If these figures are accurate, the battery capacity will increase by approximately 20 and 11 percent respectively, while the new chips are expected to deliver improved performance and energy optimization.
Internal Redesign to Accommodate Power Cells
The increased battery size in the standard iPhone 18 is reportedly enabled by a redesigned speaker and vibration motor. These structural changes free up internal space, allowing for the larger 4,430 mAh power cell.
It was noted that these hardware adjustments are intended to boost performance while maintaining energy efficiency alongside the 2-nanometer A20 chip. A diagram shared by the Chinese leak source Fixed Focus Digital, who claims to have verified the information through personal contacts, illustrates the internal configuration of these upcoming models.
iPhone 18e May Feature a 6.3-Inch 60 Hz OLED Screen
Leaks suggest that the iPhone 18e will receive a 6.3-inch OLED screen, matching the display size of the standard iPhone 18. This marks an upgrade from the 6.1-inch panel found on the iPhone 17e. Despite this, Apple reportedly plans to keep the iPhone 18e limited to a 60 Hz refresh rate. This decision persists even though the standard iPhone 17 model eventually received a 120 Hz display.
Projected Pricing Adjustments for 2027
Market analysts anticipate that the standard iPhone 18 could launch at a price point of 999 dollars. This potential increase follows a trend where the standard iPhone 17 saw its price adjusted to 899 dollars in September 2026, up from its original 799 dollar launch price.
It was reported that consumers may face higher costs for the next generation of devices despite a lack of disruptive hardware upgrades. If the 999 dollar price point is realized, users who purchased an iPhone 17 at its original price would essentially be paying an additional 200 dollars for a faster chip and a slightly larger battery, which some view as a questionable investment.
| Model | Battery Capacity | Estimated Price |
|---|---|---|
| iPhone 17 | 3,692 mAh | 899 USD |
| iPhone 17e | 4,005 mAh | Not applicable |
| iPhone 18 | 4,430 mAh | 999 USD (rumored) |
Apple Uses Shared Components to Streamline Manufacturing Costs
By utilizing the same battery and potentially the same display size for both the iPhone 18 and iPhone 18e, Apple aims to increase the number of identical components used in production.
Both models are expected to feature the A20 processor, though the iPhone 18 will retain a dual-camera system while the budget-friendly 18e will rely on a single 48-megapixel sensor. This strategy allows Apple to differentiate the models primarily through features while streamlining manufacturing costs.
RAM Allocation for Future AI Features
The iPhone 18 series is rumored to feature 9 gigabytes of RAM. This represents a modest increase from 8 gigabytes. It is suggested that this additional capacity is intended to support specific Apple Intelligence and Siri functions within the upcoming iOS 27 operating system.
Upcoming Launch Timeline
The new devices are expected to launch in the spring of 2027. Apple is also expected to introduce a model called the iPhone Air 2 alongside the standard and 18e variants, while competitor Samsung may expand its Galaxy S27 series to include four versions: the S27, S27 Pro, S27 Ultra, and S27 Plus.
