5 Tips to Fix Download and Install Button Grayed out

1 Make Sure the Battery Is More than 50%

The iPhone update process generally uses up more battery than any other app or process. Thus, if your device's battery is not more than 50%, the downloading will not be supported and the "Download and Install" Button may be grayed out. Hence, we recommend you to get your charger and give the battery digits a hike making it more than 50%. Follow this tip and check if the problem vanishes.

2 Check iPhone Storage

Besides the battery, any new update also takes the storage. So, as the next tip, we suggest you check your device's storage when you are unable to get the iOS 16/17/18 update because of grayed-out 'Download and Install button.

Go to 'Settings' > 'General' > 'iPhone Storage. Check the storage and remove unnecessary stuff to make space.
