Apple is reportedly stepping up its battery game with the iPhone 18 Pro Max. A well-known Weibo leaker Digital Chat Station shared supply chain information suggesting the device could feature a 5,100–5,200 mAh battery, paired with the A20 Pro chip built on TSMC’s 2nm process.
This combination could give users over 40 hours of real-world usage, continuing Apple’s trend of leading the industry in battery performance.
How big is the upgrade?
- Current iPhone 17 Pro Max battery: 5,088 mAh
- Expected iPhone 18 Pro Max battery: 5,100–5,200 mAh
- Battery life improvement: Potentially 1+ hour beyond the already impressive 39 hours of the iPhone 17 Pro Max
The larger battery, combined with Apple’s more efficient A20 Pro chip, means longer streaming, gaming, and browsing sessions without recharging. Apple has consistently led the market in battery life, and the 18 Pro Max could set a new benchmark for flagship phones.
What about the first foldable iPhone?
Alongside the 18 Pro Max, Apple is expected to launch its first foldable iPhone, rumored to have a battery over 5,500 mAh. That would make it the largest battery ever in an iPhone and possibly the longest-lasting foldable device in the market.
- Expected highlights: class-leading battery, foldable form factor
- Potential impact: heavy users may find it lasts well beyond a full day even under intensive use
