A filing with a regulator in Brazil says the iPhone 12 has a 2,815 mAh battery, and the iPhone 12 mini has a 2,227mAh battery
While the iPhone 12 and iPhone 12 Pro are now available for pre-order in the US, Apple is getting ready to bring its new smartphones to other countries as well.
Context & Ripple Effects
Apple no longer publishes battery capacities itself, so foreign regulator filings do the disclosing: TENAA filings revealed the iPhone 7's 1,960mAh cell in 2016, the iPhone 8's smaller-than-7 battery in 2017, and the XS/XR sizes in 2018. The Brazilian filing continues that pattern for the iPhone 12 generation, surfacing the numbers just after US pre-orders opened on October 16 and before the mini follows on November 6.
The stakes are highest for the mini: its 2,227mAh cell is the smallest battery in the filing and the smallest in recent iPhone memory, which puts the burden on Apple's claim that the A14 makes up the difference — a claim reviewers can now test against hard numbers.
First-order effects
- Buyers deciding between the iPhone 12 and the November-shipping mini now have exact capacity figures — 2,815mAh versus 2,227mAh — before the mini's pre-order window opens, replacing Apple's vague battery-life promises with comparable data.
Second-order effects
- Reviewers and teardown channels get their benchmark anchor from the filing rather than Apple, and any shortfall in real-world mini battery life lands directly on the smallest model's demand — the same model that would go on to capture only a 5% share of US iPhone sales in a later quarter, with buyers clustering in the Pro Max instead.
Third-order effects
- Regulator filings in Brazil and China are consolidating into the de facto global disclosure channel for Apple hardware specifications, since Apple's own launches increasingly skip the numbers; battery capacity becomes a figure the press extracts from governments rather than from Cupertino.
The trend: Foreign regulator filings — TENAA in China, now Brazil — have become the standing mechanism through which iPhone battery specifications reach the public before or alongside each launch.
