iPhone 17 Series: Bigger Batteries and More Endurance
Four Models, Noteworthy Battery Gains
Apple’s iPhone 17 family is comprised of four key models:
-
iPhone 17 Air: The thinnest, lightest flagship
-
iPhone 17: The standard model
-
iPhone 17 Pro: Premium features in a refined size
-
iPhone 17 Pro Max: The biggest, longest-lasting flagship yet
iPhone 17 Pro Max battery size
Latest CQC certification and reliable tipster leaks have published the following expected battery specs:
| Model | Battery Size (US/eSIM) | Battery Size (China) |
|---|---|---|
| iPhone 17 Air | 3,149mAh | 3,036mAh |
| iPhone 17 | 3,692mAh | — |
| iPhone 17 Pro | 4,252mAh | 3,988mAh |
| iPhone 17 Pro Max | 5,100mAh | 4,900mAh |
Notably, “Pro Max” becomes the largest iPhone to date, outpacing its predecessor (iPhone 16 Pro Max) by nearly 500mAh. Both Pro and Air models will offer eSIM-only versions in major markets, freeing up internal space for larger batteries.
Why Battery Size Matters: Apple vs Rivals
This year’s upgrades give Apple a boost against rivals:
-
Samsung Galaxy S25 Ultra: 5,000mAh
-
Google Pixel 10 Pro XL: 5,200mAh
-
OnePlus 13: 6,000mAh
Apple’s performance optimization regularly delivers superior endurance compared to spec-sheet numbers, with iPhones — especially the Pro Max — often besting Android competitors in real-world battery life despite smaller capacity. However, the jump to 5,100mAh for the Pro Max signals Apple’s new push for overt battery dominance.
eSIM Drives Design Evolution
A key part of the upgrade is the push toward eSIM-only models, no longer including physical SIM trays in regions outside North America. Apple has started training retail staff across Europe, including France, Germany, Italy, Spain, and the Netherlands, to educate buyers about eSIM switching and management.
Removing the SIM tray lets Apple reengineer internals for increased battery size, improved thermal management, and streamlined waterproofing — all while offering more robust device security.
Real-World Impact: Charging, Endurance, and More
Larger batteries mean:
-
Extended screen-on time for gaming and creative work
-
Longer 5G video streaming
-
Improved wireless charging cycles
-
Potential for new camera features thanks to reliable power reserves
For frequent travelers, eSIM has pros and cons: easier management and security, but less flexibility for swapping SIMs quickly.
Pricing and Upgrades
While Apple hasn’t officially confirmed battery capacities, base prices for standard models are expected to remain similar, with Air, Pro, and Pro Max variants likely to see increases of $50–$100 due to design changes and hardware enhancements.
The series also introduces upgrades to processors (A19 / A19 Pro), storage (up to 1TB), RAM (up to 12GB), and imaging — ensuring that battery isn’t the only improvement this cycle.
iPhone 17 Poised for Best-ever Endurance
The iPhone 17 family stands to redefine battery standards in Apple’s ecosystem, offering significant, tangible improvements for power users, frequent travelers, and anyone who values device longevity. As Apple faces mounting competition, all eyes are now on “Awe Dropping” launch event for a hands-on look at real-world endurance, charging speed, and overall user experience.
Whether you choose the sleek Air, the balanced standard, or the powerhouse Pro Max, battery life is finally front-and-center in the iPhone story for 2025.
