5. Get a battery replacement

Firstly, you can go to Settings > Battery and tap on Battery Health to check your iPhone battery life. If your iPhone's battery health drops below 80%, then the phone will start to throttle the processor. 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%.
