Apple‘s first foldable iPhone is back in the spotlight. A new leak suggests the upcoming iPhone Ultra could pack a 5,000mAh battery, offering one of the largest battery capacities ever seen in an iPhone.
The latest information comes from well-known tipster Digital Chat Station on Weibo, who shared details about a newly certified battery pair believed to be intended for Apple’s upcoming foldable smartphone.
Split battery hints at foldable design
According to the tipster, one of Apple’s regular battery suppliers recently had two batteries certified together, a setup commonly used in foldable smartphones due to their dual-cell battery design.
The certified batteries reportedly have rated capacities of 1,921mAh and 2,962mAh. Combined, they offer a rated capacity of 4,883mAh. Quick maths. Since manufacturers typically advertise the typical battery capacity rather than the rated value, the final marketed capacity is expected to be around 5,000mAh.
If accurate, the iPhone Ultra would feature one of the biggest batteries Apple has ever used in an iPhone.
Similar to Samsung’s rumored foldables
Interestingly, the rumored 5,000mAh battery puts the iPhone Ultra in the same range as Samsung’s upcoming foldable flagship.
Current rumors suggest the Samsung Galaxy Z Fold8 Ultra will also feature a 5,000mAh battery, despite using a different display aspect ratio.
Meanwhile, Samsung’s direct competitor to the iPhone Ultra, the Galaxy Z Fold8, is rumored to come with a slightly smaller 4,800mAh battery.
Still expected to launch this September
The iPhone Ultra is expected to make its official debut this September alongside the iPhone 18 Pro and iPhone 18 Pro Max.
Although earlier reports claimed Apple’s foldable iPhone could be delayed, more recent leaks continue to suggest that the device remains on schedule for its planned announcement.
As always, Apple has yet to officially confirm any details. However, if the latest leak proves accurate, the iPhone Ultra could launch with a 5,000mAh dual-cell battery, bringing it in line with the battery capacities expected from Samsung’s next-generation foldable smartphones.
