A Physically Larger Battery
With a smaller display, the iPhone SE 2 will most likely not have any issues with its battery life. However, I’d still like to see a bigger battery included in this device. The iPhone 8 came with a decent-sized battery, but I’d love to see an improvement.
Many people agree that a thicker device isn’t a problem if it means it’ll carry a bigger battery. Although, with the many advances in technology since the iPhone 8 was first released, a larger battery may be easy to include in its thin frame.
