Apple’s battery game might finally be getting a serious upgrade based on new details spotted in a Chinese regulatory database. A post from leaker ShrimpApplePro shows the suspected battery capacities for the full iPhone 17 lineup, and these numbers suggest real progress.
Here are the figures currently circulating:
- iPhone 17 shows a single entry of 3,692 mAh, though it is not clear if this applies to both SIM and eSIM versions
- iPhone 17 Air comes in two flavors: 3,036 mAh with a SIM tray and 3,149 mAh in an eSIM-only variant
- iPhone 17 Pro lists as 3,988 mAh for the SIM version and jumps to 4,252 mAh for eSIM-only
- iPhone 17 Pro Max breaks through previous limits with 4,823 mAh in the SIM model and a whopping 5,088 mAh if it drops the physical tray
That last figure is especially striking. If true, the iPhone 17 Pro Max would become the first iPhone to cross the 5,000-mAh threshold, delivering a significantly larger battery than the iPhone 16 Pro Max.

The pattern is clear: skipping the physical SIM tray frees up internal space, and Apple appears to be using that for extra battery capacity. It’s a smart move that turns eSIM convenience into a tangible performance benefit.
Just keep in mind that none of this is confirmed by Apple yet. Until the event hits and official specs appear, treat these numbers as solid but unverified. Still, they point to an Apple strategy that balances thinner designs, smart component decisions, and battery boosts.
If accurate, this leak offers real reason to get excited—especially for power users who want every bit of endurance they can get out of their iPhone.
