The latest iPhone models have seen a gradual increase in battery capacity, culminating in the eSIM variant of the iPhone 17 Pro Max, which features the largest battery yet, rated at 5, 088mAh. Anticipation is building as the iPhone 18 Pro Max is expected to surpass this capacity. For some time, it was widely believed that limited internal space was preventing Apple from integrating larger batteries into their devices. However, recent developments have debunked this myth, particularly highlighted by a new video showcasing an upgraded iPhone 11 Pro, which is nearly seven years old, receiving an impressive 12, 000mAh battery replacement compared to its original 3, 046mAh cell.
Enhanced Battery Design: 12, 000mAh Replacement Fits Seamlessly
The YouTube channel The Fix highlights an iPhone 11 Pro that had depleted battery health at just 67%.Faced with the necessity for a replacement, the creator opted for something extraordinary: a substantial 12, 000mAh battery upgrade. The disassembly process was remarkably straightforward, and notably, the new battery model maintained the same dimensions as the original. This suggests that the newer battery is likely a silicon-carbon variant, known for its efficient energy density without requiring additional space.
While Apple generally advises against using unofficial batteries from unauthorized manufacturers, the adoption of this battery technology by many of Apple’s Chinese competitors over recent years suggests a level of feasibility for its implementation in older models. The reinstallation of the battery appeared to be straightforward, as depicted in the image above. While the replacement battery was labeled with a capacity of 10, 000mAh instead of the claimed 12, 000mAh, this still represents a staggering 330% increase in battery life, a noteworthy enhancement by any standard.
From this intriguing upgrade story, it seems apparent that Apple intentionally opts for smaller battery sizes in its iPhones. This strategy might stem from the need to maintain stringent quality control across millions of units produced annually. Apple likely prefers to face criticism for battery size rather than risk delivering defective units that could lead to safety issues, such as overheating or fires.
