iPhone 18 Pro Max battery rumors: it could be a record-breaking year for Apple
Between a rumored capacity jump to roughly 5,567 mAh and improved power efficiency of the 2nm A20 Pro chip, the iPhone 18 Pro Max battery life could be exceptional.
Apple's upcoming iPhone 18 Pro Max is expected to deliver a record-breaking battery life, according to recent leaks. The battery capacity is rumored to range between 5,391 mAh and 5,567 mAh, marking a 10% increase over the current iPhone 17 Pro Max's 5,088 mAh. This boost in capacity, combined with Apple's next-generation silicon architecture, could push the iPhone 18 Pro Max past the 19- or 20-hour battery life threshold, potentially making it the longest-lasting iPhone ever.
The A20 Pro, Apple's next-generation chip, is expected to significantly improve power efficiency. Early leaks suggest that the A20 Pro could run up to 30% more efficient than its predecessor, the A19 Pro, on TSMC's 2-nanometer manufacturing process. This efficiency gain, paired with the larger physical battery, could result in an impressive 20-hour runtime on benchmarks.
If Apple manages to achieve this, the iPhone 18 Pro Max would set a new standard for battery life in the smartphone industry, surpassing even the Galaxy Z Fold 8 Ultra and OnePlus 15, which currently hold the longest-lasting flagship titles.
