Apple’s iPhone 17 series brought more than just a new design and the eye-catching Cosmic Orange finish. For the first time, Apple is selling the same phone with different battery sizes depending on the region.
The eSIM-only iPhone 17 Pro and Pro Max — available in the U.S., UAE, Saudi Arabia, Canada, Japan, and other markets — feature a larger battery than the physical SIM models.
During Apple’s September keynote, the company revealed that removing the Nano SIM tray allowed them to use that space for a bigger battery.

According to GSMArena’s detailed test, the eSIM iPhone 17 Pro achieved a clear endurance edge over the regular Nano SIM version.
Test Type | iPhone 17 Pro (eSIM) | iPhone 17 Pro (SIM) | Difference |
|---|---|---|---|
Battery Capacity | 4252 mAh | 3998 mAh | +6.35% |
Active Use Score | 16 hrs 12 min | 15 hrs 23 min | +49 min |

The eSIM variant gives users about an extra hour of heavy usage per charge.
Apple’s claim of “two extra hours of video playback” was not confirmed in GSMArena’s repeated tests.
The biggest advantage appears in web and gaming performance, suggesting better power efficiency rather than just capacity gain.
By removing the physical SIM slot, Apple achieved:
More internal space for a larger battery
Simpler waterproofing and durability
Push toward eSIM adoption globally
Apple is expected to go eSIM-only worldwide once all major carriers support it.
