Can Battery Health 99 be restored 100?

I can't. Battery health 99 indicates that the battery has a certain loss. With the increase of use time and times, the performance of the battery will gradually decline, which is caused by the chemical substances inside the battery can not give full play to its effectiveness. Even if the battery health is restored to 100% by some methods, its actual performance is difficult to reach a brand-new battery level. Due to physical wear and chemical aging and other factors, the performance of the battery is degraded, and the battery health 99 cannot be restored to 100.
