iPhone 17 Pro’s Slim Battery Leaked

Apple’s iPhone 17 series is coming soon, and leaks are stirring excitement. A new leak reveals the iPhone 17 Pro’s battery, sparking talk about its slim design. First thought to be for the iPhone 17 Air, this battery belongs to the Pro model. With a September 2025 launch nearing, let’s dive into what this means.

A Sleek but Small Battery

Tipster Majin Bu shared images of a thin battery in a steel frame, like the iPhone 16 Pro’s setup. Its slimness stands out, perfect for a sleek phone. Bu says it has a 2,900 mAh capacity, down from the iPhone 16 Pro’s 3,582 mAh. That’s closer to the iPhone 12’s 2,815 mAh than a modern flagship’s battery.

Apple’s knack for efficiency might save the day. iOS 26 tweaks and better battery tech could stretch this smaller cell to last a full day. Still, some worry if 2,900 mAh can handle the Pro’s features, like Apple Intelligence and the A19 Pro chip.

Why a Smaller Battery?

Rumors suggest the iPhone 17 Pro keeps its predecessor’s size, unlike the chunkier iPhone 17 Pro Max, which may boast a 5,000 mAh battery. Apple seems to prioritize a slim design for the Pro. The steel frame, seen in the iPhone 16 Pro, likely aids heat dissipation, crucial if the A19 Pro runs hot.

X posts are abuzz about this. Some users praise the slim design, while others question the battery life trade-off. One post noted the steel case boosts resistance and cooling, which might balance the smaller capacity. But with 8K video and a possible 120Hz ProMotion display, will it hold up?

Key Points of the Leak

Here’s what you need to know:

• Slim Design: The battery’s thin, with a steel frame for heat control and durability.
• 2,900 mAh Capacity: It’s smaller than the iPhone 16 Pro’s 3,582 mAh, sparking endurance concerns.
• iOS 26 Boost: Software tweaks might help the battery last a full day.
• September Launch: Expect the iPhone 17 series, including the Pro, around September 8-10, 2025.
• Trade-Offs: A slimmer profile could mean less battery stamina than the Pro Max.

What’s the Bigger Picture?

Apple often balances style and function. The iPhone 17 Pro leans toward a sleek look, unlike the Pro Max’s focus on battery power. This could attract users who want a premium phone without bulk. If Apple’s efficiency works, the Pro might still shine despite its smaller battery.

The iPhone 17 series may include a 48MP telephoto lens, 12GB of RAM, and a wide camera bump. Faster 35W wired charging and Qi2.2 wireless charging could help too. But power users might prefer the Pro Max or standard iPhone 17 for better battery life.

What’s Coming Next?

Apple’s big reveal is likely in early September. The iPhone 17 lineup—standard, Pro, Pro Max, and Air—will be diverse. The Air, with a rumored 2,800 mAh battery, targets style-focused users. The Pro balances high-end features with a sleeker build.

Some X users call the 2,900 mAh battery a step back, especially against rivals like the Samsung Galaxy S25 Edge. But Apple might have tricks, like a high-density battery or AI-driven power-saving mode. We’ll know more after real-world tests post-launch.

For now, this leak hints at Apple’s next move. Can the iPhone 17 Pro’s slim battery keep up? We’ll find out when Apple unveils it this fall.
