With just under two days to go until Apple’s highly anticipated event, excitement is building as multiple leaks surface concerning the iPhone 17 lineup. This latest leak focuses on battery capacities, revealing what could be a pivotal advantage for eSIM users!

Battery Capacities Revealed!

Renowned Apple insider ShrimpApplePro has shed light on the battery specifications for the upcoming iPhone 17 models, giving us a clearer picture of what to expect. Here’s the breakdown:

- **iPhone 17:** 3692mAh (3.6% increase from iPhone 16) - **iPhone 17 Air:** 3149mAh/3036mAh (48% drop from iPhone 16 Plus) - **iPhone 17 Pro:** 4252mAh/3988mAh (up to 18.6% increase from iPhone 16 Pro) - **iPhone 17 Pro Max:** 5088mAh/4823mAh (up to 8.6% increase from iPhone 16 Pro Max) These capacities indicate significant improvements, particularly for the standard iPhone 17 Pro.

eSIM users Rejoice: More Battery for You!

For the redesigned iPhone 17 models—17 Air, 17 Pro, and 17 Pro Max—Apple seems to finally be capitalizing on the extra space freed by eliminating the physical SIM card tray. If you own an eSIM-only iPhone, you could enjoy an additional battery capacity of around 5% compared to users with physical SIMs.

The iPhone 17, however, only lists a single battery capacity. It's likely that its design closely mirrors that of the iPhone 16, which may mean no extra advantage for eSIM users here.

In detail, the eSIM-only models boast the following capacities over their physical SIM counterparts:

- **iPhone 17 Air:** 3.7% extra capacity - **iPhone 17 Pro:** 6.6% extra capacity - **iPhone 17 Pro Max:** 5.5% extra capacity
