Apple iPhone 18 and 18e Rumored to Feature Identical Battery and Display Sizes
The upcoming iPhone 18 lineup might be moving toward greater hardware parity in key areas. According to recent leaks, both the standard iPhone 18 and the budget-oriented iPhone 18e are expected to feature identical battery capacities and display sizes, marking a significant shift in how Apple might differentiate its mid-range and flagship models.
According to a report from leaker Fixed Focus Digital via Weibo, the iPhone 18 is expected to see a substantial jump in battery life. The device is rumored to house a 4,430 mAh battery, which would represent a roughly 20% increase over the 3,692 mAh capacity found in the iPhone 17. Interestingly, the iPhone 18e is also expected to adopt this same 4,430 mAh capacity, bringing the entry-level model closer to the flagship in terms of endurance.
The SIM-less Trade-off
This increased capacity likely comes at a cost to physical versatility. The leaks suggest that Apple may achieve these larger batteries by removing the physical SIM card slot, a move already seen in other regions. However, it remains uncertain if this change will be implemented globally; users in markets like Germany, where physical SIM slots are still standard, might not see the benefit of the larger battery if Apple maintains the slot in those regions.
Display Parity with Refresh Rate Divergence
The display specifications also point toward a shift in sizing. Both the iPhone 18 and the iPhone 18e are rumored to feature 6.3-inch OLED panels. This would be a departure from previous rumors suggesting the 18e would stick to a smaller 6.12-inch display. However, while the physical size might be the same, the technology will differ significantly. The iPhone 18 is expected to utilize an LTPO OLED panel supporting a 120 Hz refresh rate, whereas the iPhone 18e is likely to remain limited to a standard 60 Hz refresh rate.

A20 SoC and Camera Variations
Under the hood, both devices are expected to be powered by Apple's A20 SoC, reportedly manufactured using TSMC's 2-nanometer process. Despite the shared silicon, the camera systems will remain a primary differentiator. The standard iPhone 18 is expected to retain a dual-camera setup (Main and Ultra-wide), though the main sensor might be physically smaller than its predecessor despite maintaining a 48 MP resolution. In contrast, the iPhone 18e is rumored to feature only a single 48 MP main camera.
If these rumors hold true, the unveiling of the iPhone 18, iPhone 18e, and potentially an 'iPhone Air 2' is expected in the spring of 2027, likely around March or April.
