iPhone 12 Charging issue

Hello! I use the Anker Wakey to charge my iPhone 12 at night. Lately, after I get the phone charging (indicated by the blue light), it will stop charging and the blue light will start flashing. Has anyone else had issue with this? TIA!

Do you have a case on your iPhone 12? If so, does temporarily removing the case make a difference?

This would be the new IPhone correct? If so it has a magnet around its charging coil which causes the wake and almost any wireless charger to detect the magnet as a foreign object thus causing it to not charge and the blue light to flash rapidly before shutting off. Effectively, some users have found that by elevating the phone slightly off the qi charging pad they can bypass the foreign object detection and get wireless charging to work. But you will have to play around with distance and what not from the base and your phone to get it to work properly
