iPhone Ultra Battery Leak: Massive Upgrade Expected?

Is the iPhone Ultra Finally Getting a 5,000 mAh Battery?

Rumors surrounding Apple’s first foldable device have been swirling for years, but recent leaks finally give us a concrete look at what might be powering the much-anticipated iPhone Ultra. A recent post on Weibo from the reliable leaker Digital Chat Station suggests that a key battery supplier has officially certified a pair of batteries designed specifically for a foldable device.

Since foldable smartphones require a dual-cell setup to accommodate their folding architecture, seeing two distinct battery units is a major hint. The certified capacities sit at 1,921 mAh and 2,962 mAh, resulting in a combined rated capacity of 4,883 mAh. When you translate that to typical marketing speak, we are looking at a 5,000 mAh total capacity. That’s a significant milestone for a foldable iPhone.

Interestingly, this puts the iPhone Ultra right in line with the competition. Rumors suggest the upcoming Samsung Galaxy Z Fold8 Ultra will likely pack a similar capacity, while the standard Galaxy Z Fold8 is expected to hover around 4,800 mAh. Apple isn’t just trying to catch up; they seem to be aiming for a very competitive power profile.

When Can We Expect It?

Despite previous industry whispers suggesting production delays, the latest reports indicate that the iPhone Ultra is still on track for a September launch. Apple is expected to unveil it alongside the iPhone 18 Pro and iPhone 18 Pro Max, setting the stage for one of the most significant hardware events in recent years.

Whether you are a long-time iOS loyalist or just curious about how Apple will tackle the foldable form factor, the combination of a 5,000 mAh battery and Apple’s ecosystem integration makes this a launch to watch closely.
