Mojang can be slightly ignorant of performance issues. However minecraft 1.13 is probably a performance update as it is called the optimisation update. However, a mod called optifine could help if you set chunk update speed to 1 fast render on fast maths on and lazy chunk loading on. If it runs at like 1fps however, turn lazy chunk loading off. Hope this helps😃. Idk if it does as I am not a laptop user but I have looked at processor loads and this (in theory) should help.
I have had that problem before! It is caused by sprint rapidly engaging and disengaging and how I usually combat it is to stop sprinting and start again and back to normal 😃
