The reason for throttling is because the battery might not be able to sustain the power when the CPU goes to max-speed under load. "Below 80% means the battery has chemically aged and so it cannot deliver the performance you would expect from a battery that otherwise is not chemically aged. Peak performance will auto-enable to help stop the device shutting down or crashing but the trade-off is slow performance". So one of the best things you can do is to get a battery replacement. Apple will replace your battery for a lower price if it’s under 80%.
