Less than a week before Apple’s September 9 “Awe-dropping” event, a Weibo-based leaker suggests that the iPhone 17 Pro and its bigger Pro Max sibling will be a performance powerhouse. Based on the latest information, these models will come with a new thermal management solution, improvements in battery life, and display brightness.

If accurate, these changes could mark one of the most significant upgrades for the iPhone in recent years. According to the leak, Apple is preparing the iPhone 17 Pro and iPhone 17 Pro Max with a redesigned thermal management system, which will address one of the most common issues faced by users during heavy workloads. This involves reducing thermal throttling, which currently caps performance when the device temperature rises to protect internal components and prevent crashes.

Alongside these changes, the iPhone 17 Pro models are also slated to feature sustained outdoor brightness capabilities. Unlike previous iPhone models that could briefly reach peak brightness before dimming to manage heat, this year’s models are rumored to maintain higher brightness consistently. This improvement would directly benefit users who frequently record videos or use their phones in direct sunlight, making the display more reliable under challenging conditions.

Battery life is another area where Apple appears to be making meaningful progress compared to current models. The company will achieve this by combining a bigger battery, improved efficiency from the new thermal design, and the new A19 Pro chip. With all of these factors combined, the iPhone 17 Pro will deliver the best and longest-lasting battery on any iPhone yet. For many users, this could mean that the device will last more than an entire day of demanding use without needing to recharge.

In a unique start to his ruling against President Donald Trump’s administration on September 30, U.S. District Court Judge William Young included a scanned handwritten note sent to his office. The note read: “Trump has pardons and tanks – what do you have?” At the top of Young’s opinion in AAUP v. Rubio, which ruled that Trump’s effort to deport foreign-born student protesters was unconstitutional.

It is worth noting that not all enhancements will be available on the ultra-thin iPhone 17 Air model. The iPhone 17 Air will get the A19 Pro chip with a 5-core GPU but will miss out on the new thermal management system and a bigger battery, meaning it won’t have sustained brightness levels.

The devices are slated to launch in a week, and we will be covering the launch event extensively. So, keep an eye out for more last-minute leaks.
