iPhone 18 Pro battery life compared to iPhone Duo and iPhone 17 Pro

Apple’s new iPhone 18 Pro lineup delivers meaningful battery-life gains, with the Pro model up about 10% and the Pro Max up about 14% versus the prior generation, while the new iPhone Duo offers respectable but not category-leading longevity given its dual-display design. For CIOs and IT leaders, the strategic takeaway is that Apple is improving device endurance enough to support more mobile work with fewer charging interruptions, but enterprise deployment planning should still account for real-world validation, especially for the Duo and for markets using physical SIM trays that slightly reduce battery performance.
