A recent report from Rozetked indicates that Apple’s forthcoming iPhone 18 Pro Max could see a notable upgrade in battery life. The eSIM-only version of the flagship device is rumoured to feature a 5425 mAh battery while the model retaining a physical SIM slot may include a slightly smaller 5235 mAh cell.
These figures represent an estimated 7% to 8% capacity increase compared to the iPhone 17 Pro Max which houses 5088 mAh and 4832 mAh batteries for its respective versions. In stark contrast the same source claims that the Samsung Galaxy S27 Ultra will maintain a 5000 mAh battery for the eighth consecutive year. Naturally these specifications remain unconfirmed until Apple officially unveils the new hardware.
Anticipated release timeline and displays
Industry whispers suggest the high-end iPhone 18 Pro and Pro Max models will launch in September 2026. This autumn hardware event might also serve as the debut for Apple’s very first foldable smartphone. Meanwhile the standard iPhone 18 and a new iPhone 18e are reportedly delayed until the spring of 2027.
Display dimensions are expected to remain unchanged at 6.3 inches for the Pro and 6.9 inches for the Pro Max. However the Dynamic Island could shrink by approximately 35% as engineers are purportedly moving several Face ID components directly beneath the screen to create a cleaner viewing experience.
The premium smartphones are expected to be powered by the A20 Pro chip which is built upon a cutting-edge two-nanometre manufacturing process. This advanced processor should deliver superior performance alongside enhanced energy efficiency to further maximise the upgraded battery capacity.
Connectivity is also set for a major overhaul with the anticipated inclusion of Apple’s proprietary C2 modem. This bespoke component will support high-speed mmWave networks and is rumoured to feature an automatic switch to satellite communication whenever traditional mobile coverage drops out.
Photography and design enhancements
For photography enthusiasts the primary camera is tipped to feature a variable aperture for the very first time. This addition will give users precise control over light intake and depth of field. The telephoto lens is also expected to receive a wider aperture to drastically improve low-light performance. Apple may complement these hardware changes by integrating professional-grade settings directly into the default camera application.
While the overall aesthetic of the phone will remain familiar the rear camera module is projected to grow in size. Other subtle design tweaks include a simplified Camera Control button, a more uniform back panel that eliminates the previous two-tone transition and fresh colour options such as a striking dark red finish.
