You should regularly take a moment to check on your iPhone’s battery life. And given how easy Apple made it starting in iOS 11.3, we really have no excuse. All you have to do is hit Settings > Battery > Battery Health, and you’ll be able to see the maximum capacity of your iPhone’s battery, ensure “Optimised Battery Charging” is enabled to give you as much battery life as possible, and check for that handy little “you’re screwed” message from Apple if your battery has degraded enough that it’s starting to affect your iPhone’s performance.
