Starting December 19th Samsung will begin to send out an update that will prevent you from charging your Galaxy Note 7. Once your phone finally runs out of the juice from its last charge you will no longer be able to use the device. It will essentially be a brick, paper weight, door jam... you get the picture. Samsung has already updated many Galaxy Note 7 devices to only allow for a 70% charge. Those updates also include a change to the battery indicator. There is now a custom kernel that takes away charging restrictions on the Galaxy Note 7. If you want your Note 7 to work after December 19th you will need to flash the custom kernel. I actually won't link to the kernel here as I think it would be quite irresponsible to continue to go on using the Note 7 with the potential for it to catch fire at any moment. If you must you can easily find what you need.
