Apple rarely makes big changes to its existing designs, so you cannot expect huge changes in iPhone 15 battery sizes.
Apple calls its iPhones "all-day" devices, but we feel that with moderate use the iPhone Plus and Pro Max could be used two days between charges, with only the smaller models being one-day devices.

*projections based on iPhone 14 battery sizes.
Will Apple increase charging speeds with the advent of USB-C charging on the iPhone? We don't have high hopes, but it's reasonable to expect around 25W charging speeds on the smaller models, and 30W charging for the two larger models.
All four iPhone 15 models are also expected to have MagSafe wireless charging, the magnetic charging solution by Apple that can be quite convenient.
