Base Station Pro is not charging iPhone to 100% after charging overnight or is slow charging
This is normal and expected behavior for the current firmware when charging an iPhone. Base Station Pro on the current firmware V1.1.0 takes 3 to 4 hours to charge 0-80% and can take anywhere from 3 to 8 hours to charge the last 80-100% battery. We agree that this isn't optimal behavior and Aira’s team of engineers is currently working on improving the time to charge the last 80-100% battery for iPhones and releasing the improvements in a future firmware update.
We are still hard at work with Aira’s FreePower team making additional improvements for future firmware updates.
