Apple iPhone 18 Pro Max: Longer Battery Life with 2nm Chip

Key Takeaways

1. Apple is planning two models of the iPhone 18 Pro Max: an eSIM-only version with a battery capacity of 5,100-5,200 mAh and a classic version with a 5,000 mAh battery.

2. The new battery sizes for the iPhone 18 Pro Max are slightly larger than the iPhone 17 Pro Max models, which have 5,088 mAh (eSIM) and 4,832 mAh (nano-SIM).

3. While Apple’s batteries are smaller than some Android phones that can have up to 10,000 mAh, there may be options for improved battery life in the iPhone 18 Pro series by 2026.

4. This year will see the launch of Apple’s first 2nm chip, the Apple A20 Pro, which is expected to be more energy-efficient.

5. The Apple A20 chip in the iPhone 18 Pro models will not be the first 2nm chip on the market, as Samsung’s Exynos 2600 is expected to launch in Galaxy S26 models soon.

Based on news from the supply chain, a Chinese source known as Digital Chat Station has shared some clear details about the battery sizes that Apple is looking at for the iPhone 18 Pro Max, which is anticipated later this year. There will be two models of the iPhone 18 Pro Max: one is an eSIM-only version that will have a battery capacity of approximately 5,100 mAh to 5,200 mAh, while the other is a classic version that includes nano-SIM slots and will have a 5,000 mAh battery.

Battery Size Comparisons

These new battery sizes are a bit larger than those in the current iPhone 17 Pro Max models, which have a 5,088 mAh battery in the eSIM model and a 4,832 mAh battery in the nano-SIM model. While Apple’s batteries are smaller compared to some Chinese Android phones that have batteries reaching up to 10,000 mAh, like the Honor iPhone 17 Pro clone, it is believed that Apple might introduce another option to enhance battery life for the iPhone 18 Pro series by 2026.

Upcoming Chip Technology

Additionally, this year marks the introduction of the first 2nm chip, the Apple A20 Pro, which is expected to be more energy-efficient due to its smaller manufacturing process. However, it seems the Apple A20 in the iPhone 18 Pro and iPhone 18 Pro Max will not be the very first 2nm chip on the market. Samsung’s Exynos 2600, which also utilizes a 2nm manufacturing process, is anticipated to launch in some Galaxy S26 models soon, though it will be produced by Samsung, not TSMC.
