Apple MacBook M1 suddenly lost the battery charge and turned off

When you Startup in Safe Mode font caches are removed.

That is not related to Battery problem.

If there is a macOS related issue, startup in Safe Mode may rectify.

Startup in Safe Mode involves restart.

Resetting SMC is a standard hardware related troubleshooting step.

     Safe mode prevents your Mac from loading certain software when it starts up, including login items, 

     system extensions not required by macOS,

     and fonts not installed by macOS. It  also does a basic check of your startup disk, 

     similar to using First Aid in Disk Utility. 

     And it deletes some system caches, including font caches and the kernel cache, 

     which will be created again automatically as needed.

3. Contact Apple.
