Your iPhone’s aging lithium-ion batteries will eventually start to lose their ability to retain a charge — and that can be highly frustrating, especially if you’re out and about all day. If that is happening to you, there are several solutions: you can switch over to the latest iPhone, start carrying a battery charger around with you, or — simply replace the battery.
To first identify whether your battery is ready for a change, you can check to see what the current health of your battery is by going to “Settings” > “Battery” > “Battery Health.” This is where you can find out your battery’s current maximum capacity. A small notice at the very top may appear if your iPhone’s battery is ready for a swap.
