What are the differences in battery life between the 11-inch and 13-inch iPad Pro when using ProRes 4444

Battery Capacity and General Usage:
- The 11-inch iPad Pro has a built-in 31.29-watt-hour battery, while the 13-inch model features a larger 38.99-watt-hour battery[1][9]. This difference in battery capacity generally translates to longer battery life for the 13-inch model under similar usage conditions.
- In general use, such as web browsing or video watching, Apple claims both models can last up to 10 hours on Wi-Fi[1][9]. However, real-world tests often show the 13-inch model outperforming the 11-inch in terms of battery endurance, with some tests indicating the 13-inch can last around 13 hours or more[3][4].

ProRes 4444 Video Editing:
- ProRes 4444 is a high-quality video codec that requires significant processing power and storage space[5][8]. While Apple's ProRes technology is designed for efficient editing performance, it still demands more power than standard video formats.
- The M4 chip in both iPad Pro models provides robust performance, but the larger battery in the 13-inch model may offer an advantage in sustained video editing tasks, potentially allowing for longer editing sessions without needing a recharge.
- However, specific battery life differences when using ProRes 4444 are not well-documented in the available data. The general trend suggests that the 13-inch model would have a longer battery life due to its larger battery capacity, but actual performance can vary based on factors like screen brightness, usage patterns, and whether additional power-consuming accessories are used.

Additional Factors:
- Screen Size and Brightness: The larger screen of the 13-inch model consumes more power, especially at higher brightness settings. However, its larger battery helps offset this increased power consumption.
- Accessories and Connectivity: Using accessories like the Magic Keyboard can significantly impact battery life, as they consume additional power for backlighting and Bluetooth connectivity[7].

In summary, while specific data on ProRes 4444 editing is limited, the 13-inch iPad Pro generally offers longer battery life due to its larger battery capacity. However, actual performance can vary based on usage patterns and additional factors like screen brightness and accessory use.
