iPhone 13 series battery specifications leaked ahead of WWDC 2021 Apple Event

Apple iPhone 13 series launch is rumoured for September 2021. The company is expected to launch four new iPhone models as a successor to the iPhone 12 series. These include the iPhone 13, iPhone 13 mini, iPhone 13 Pro and the 13 Pro Max. Ahead of the WWDC 2021 Apple event, where the company is expected to unveil iOS 15 and a new MacBook Pro, iPhone 13 series battery specifications have leaked online.

Chinese tipster Digital Chat Station has leaked the alleged iPhone 13 series battery details ahead of the official launch. The tipster has listed the battery capacity of three iPhone 13 models, which are suspected to be the iPhone 13 Pro Max, iPhone 13 Pro, and iPhone 13 mini. Considering the iPhone 13 Pro and iPhone 13 share the same form factor, they are likely to have the same battery capacity.

The tipster claims that the top-end 2021 iPhone 13 Pro Max will pack a 4,352 mAh battery as opposed to the 3,687 mAh battery on the iPhone 12 Pro Max. The iPhone 13, iPhone 13 Pro will have a 3,095 mAh battery. Lastly, the iPhone 13 mini will pack a 2,406 mAh battery, which is marginally bigger than the 2,227 mAh cell on the iPhone 12 mini (Review).

The bigger batteries make complete sense as Apple is rumoured to introduce 120Hz OLED displays on the Pro models. Previous reports claimed the iPhone 13 Pro models will feature a 120Hz OLED display. 

The iPhone 13 Pro and vanilla iPhone 13 are tipped to feature a 6.1-inch display, whereas the iPhone 13 Pro Max will come with a 6.7-inch screen. There is also a 5.4-inch iPhone 13 mini rumoured to launch alongside. The display size is the same as the current generation iPhone 12 models, namely iPhone 12 (review), iPhone 12 mini, iPhone 12 Pro and iPhone 12 Pro Max.  

While the display size is the same, the notch is getting smaller on the iPhone 13 series by 33 percent. Leaked iPhone 13 render images revealed that the earpiece has been moved to the top bezel for making more space. Apple still has the Face ID sensors on the iPhone 13. Another feature coming to the iPhone 13 Pro series is Always-on Display.  

On the back, the camera bump is said to be bigger than that of the iPhone 12 Pro. It is suspected that Apple could pack a bigger sensor in iPhone 13 Pro models, which may result in a larger camera module. It will house three camera sensors with the LED flash and the LiDAR sensor.

A report had earlier claimed that all four iPhone 13 models will feature an upgraded ultrawide camera lens with a wider f/1.8 aperture. Analyst Ming-Chi Kuo, however, had reported the upgraded ultrawide camera will only be found on the iPhone 13 Pro and iPhone 13 Pro Max.
