## Apple never tells you this
Battery capacity is one of the few numbers Apple keeps off its spec sheet. You normally wait for a teardown to find out what is actually inside the phone.
## A rule did what leaks could not
European energy labelling rules make manufacturers file battery and durability data into a public database. Apple has to comply to sell the iPhone 18 Pro in the EU.
## The 18 Pro gained real capacity
Those filings show this year's Pro sitting above the iPhone 17 Pro rather than holding flat, which is the upgrade Apple hinted at on stage without ever naming a figure.
## Pro Max takes the crown
The larger body carries the biggest cell in the lineup, so the Pro Max stays the pick if screen-on time is the thing you actually care about.
## US buyers get a different one
The Pro Max sold in the US is listed with a spec tweak the international model does not share, a regional split that goes back to Apple stripping the SIM tray from US iPhones.
## Why the filings matter
Regulation is now a more reliable spec source than the keynote. Expect battery, repairability and durability numbers to leak this way every September.
## Key takeaway

The iPhone 18 Pro line got a real battery increase over the 17 Pro, and the US Pro Max is spec'd differently from the model sold everywhere else.
