A major problem with the MacBook Pro 2017 battery

[vahla]

Excuse me to write new I use the MacBook Pro 2017 all day and sometimes charge it at 50% battery life and sometimes charge at 20% to spend 66 cycles now but suddenly battery health has dropped by 4% and It got to 87%. I'm really worried. Can anyone help me?

If the laptop suddenly isn't able to charge or battery life if significantly shorter, then your only [viable] option is to have Apple replace it. The sad fact is that the battery is glued to the top case, so a DIY solution is not for the faint of heart.

Your problem is not of technical nature but rather a psychological one. My advice: stop looking at battery stats
