iPhone 18 Pro will have only a fractionally higher capacity battery

AI-summarised brief · reviewed before publication

A new leak claims that the forthcoming iPhone 18 Pro will have a battery capacity of 4,288 mAh for the US version and 4,056 mAh for the Chinese version, which still requires a physical SIM card. This represents a minor increase from the iPhone 17 Pro, with the US version showing a 0.85% improvement and the Chinese version showing a 1.71% improvement. The iPhone 18 Pro will also feature Apple's first 2-nanometer processor, the A20, which is expected to be more power efficient and potentially improve battery life.

💡 Why It Matters

  • · The iPhone 18 Pro's minor battery capacity increase may be offset by the cost of Apple's new 2-nanometer processor, which is believed to be around twice as expensive as its predecessor.
  • · This could lead to higher prices for the new device, potentially impacting consumer demand and Apple's profit margins.
