BlackBerry KEYone battery

I just had a new battery installed in my KEYone. Hopefully this will cure my problem where the old battery would not take a full charge and would shutdown when the battery was down to 30-40%. Is it a good idea to fully discharge the new battery before charging it?

I’ve always thought it was the recommended action, but many here say that’s unnecessary with modern batteries.
