The battery capacities for the upcoming iPhone 17 models have been leaked, showing significant gains for the eSIM-only models. The standard iPhone 17 has a 3692mAh battery, while the 17 Air has a 3149mAh battery (a 48% loss compared to the iPhone 16 Plus). The 17 Pro and Pro Max models have battery capacities of up to 4252mAh and 5088mAh, respectively. This represents a 3.7% to 6.6% additional capacity for eSIM-only iPhones compared to their physical SIM counterparts.

Apple is gearing up for its September 9 launch event, where the company is expected to unveil the iPhone 17 series. Leaked information suggests significant battery capacity gains for the upcoming models, particularly for the eSIM-only variants. Here's a breakdown of the battery capacities for the iPhone 17 series:

1. iPhone 17: The standard iPhone 17 is expected to come with a 3692mAh battery, a notable improvement over the previous generation's 3692mAh battery.

2. iPhone 17 Air: The iPhone 17 Air, Apple's thinnest iPhone to date, is rumored to have a 3149mAh battery. This represents a 48% loss compared to the iPhone 16 Plus, which had a 6000mAh battery. Despite this, the iPhone 17 Air is expected to be the thinnest iPhone yet, measuring 5.5mm thick [1].

3. iPhone 17 Pro and Pro Max: The iPhone 17 Pro and Pro Max are expected to feature up to 4252mAh and 5088mAh batteries, respectively. These models are also expected to come with the new A19 Pro chip, which promises improved power efficiency and better heat management [2].

The iPhone 17 Pro Max is particularly notable for its 5088mAh battery, which is a significant upgrade from the previous model's 4352mAh battery. This upgrade is expected to provide longer-lasting battery life and improved performance, especially for gaming and other power-intensive tasks.

However, the launch of the iPhone 17 Air in China may face delays due to eSIM infrastructure issues. The eSIM system in China is not fully ready for nationwide rollout, which could affect the phone's launch in one of Apple's most important markets [1]. Despite this, Apple is expected to continue its rollout of eSIM technology in China, with China Unicom already offering eSIM support for iPads and Apple Watches, although the timeline for iPhones remains unclear [1].

In conclusion, the iPhone 17 series is expected to bring significant improvements in battery life and performance, particularly for the eSIM-only models. However, the launch of the iPhone 17 Air in China may be delayed due to eSIM infrastructure issues. Apple is expected to continue its rollout of eSIM technology in China, with support for iPads and Apple Watches already available.
