Apple’s longstanding practice of not disclosing exact battery capacities in its device specifications has left consumers eager to rely on teardowns or regulatory certifications for this information. Recently, China’s regulators provided certification details that shed light on slight increases in battery sizes for the new iPhone 15 models.
Breaking it down, the iPhone 15 features a 3,349 mAh battery, a marginal uptick from the iPhone 14’s 3,279 mAh. The iPhone 15 Plus boasts a 4,383 mAh battery, surpassing the iPhone 14 Plus’s 4,325 mAh. The iPhone 15 Pro carries a 3,274 mAh battery, representing an increase from the iPhone 14 Pro’s 3,200 mAh. Meanwhile, the iPhone 15 Pro Max takes the lead with a 4,422 mAh battery, exceeding the iPhone 14 Pro Max’s 4,323 mAh.
It’s important to note that these battery size increments, although present, are relatively modest. Significant improvements in battery life are more likely to result from advancements in chipset efficiency and screen technology, rather than these minor sub-100 mAh gains.
The iPhone 15 series was recently unveiled at an Apple event and is now available for pre-order in numerous global markets.
