iPhone 18 Battery Capacity Jumps Sharply
Apple plans to equip the upcoming base iPhone 18 and an entry-level sibling with identical 4,430 mAh batteries, representing a 20.6% capacity increase over the iPhone 17.
Leaker Fixed Focus Digital published the component images on Weibo, showing a notable physical enlargement compared to the previous 3,671 mAh cell. The iPhone 17e previously carried a 4,005 mAh battery, giving the new generation a 10.6% boost over that specific model.
Internal Layout Changes Enable Larger Cells
Engineering shifts within the chassis make room for the bigger power source. igen.fr reported that modifications to the lower speaker and the Taptic Engine clear out enough internal volume to accommodate a slightly bulkier module. These space-saving tweaks allow both entry-level devices to share identical battery hardware.
iPhone 18e Display Expands to 6.3 Inches with Dynamic Island
The screen specifications are also aligning across both affordable handsets. Fixed Focus Digital reported that the display on the iPhone 18e will expand to 6.3 inches, matching the standard iPhone 18. This sizing shift suggests Apple will finally drop the screen notch on the cheaper model in favor of the Dynamic Island, mirroring changes reported by iGeneration.
A20 Chip Powers Devices with Varying Refresh Rates
ProMotion technology remains exclusive to higher-end tiers. The iPhone 18e display stays capped at 60Hz, while the standard iPhone 18 retains an adaptive refresh rate reaching 120Hz. Processing power will come from an A20 chip built on a 2-nanometer process, paired with 9 GB of RAM—a one-gigabyte increase over the preceding A19 hardware.
