iPhone 12 Pro Max Has Smaller 3,687 mAh Battery According to Regulatory Filing

Apple's new iPhone 12 Pro Max is equipped with a 3,687 mAh battery, which is around 7% less capacity than the 3,969 mAh battery in the iPhone 11 Pro Max, according to a regulatory filing published by TENAA, the Chinese equivalent of the FCC.

The regulatory filing, spotted by MacRumors, also lists the iPhone 12 Pro Max with 6GB of RAM as seen in benchmark results last week.

Apple has filed many products with TENAA over the years, and the listings have proven to be accurate on multiple occasions. Last year, for example, accurate battery capacities and RAM in the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max appeared in the database a few days prior to those devices launching. A rumor also suggested that the iPhone 12 Pro Max would have a 3,687 mAh battery earlier this year.

Despite having a smaller battery, Apple's tech specs indicate that the iPhone 12 Pro Max has the same battery life as the iPhone 11 Pro Max, with both devices providing up to 20 hours of video playback and up to 80 hours of audio playback.

Apple never discloses battery capacities or RAM on its iPhone tech spec pages, but teardowns of the new devices should confirm these details in the coming days.

I dunno why is hard for Apple, they successfully creating high efficiency chips but very hard to increasing battery capacity. Instead when Apple introduced more efficient AX chips, they also reducing mAH as possible.

Do the both should be win win for customer, especially with 5G tech which consumes more juices.

This is incorrect. Apple discloses battery capacities for all their products. They are legally obligated to do so.

The info is listed on the bottom of this page:
