Your iPhone’s Battery Is Draining Too Fast
If your iPhone is a bit older, you might feel like the battery doesn’t last as long as it used to. Unfortunately, this is normal in any device with a rechargeable battery. As batteries age through normal use, they gradually lose their ability to hold as much energy as they once did.
To find out how much capacity your battery still has, you can go into your iPhone’s Settings app and select Battery > Battery Health. You’ll see a percentage here that indicates how much juice your battery can still hold compared to what it could when it was new. This will give you a good idea if the problem is your battery’s age, or if it’s something else.
Unfortunately, if your battery’s maximum capacity has dropped below an acceptable level, there’s no magic fix — you’ll either need to live with it or have it replaced. The good news is that replacing it isn’t as complicated as you might think, and if you have the necessary tools, you can even do it yourself. Of course, it might be easier to let an expert do it for you. Plus, if your iPhone is still under warranty or an AppleCare+ plan, there’s a chance you can get it replaced for free.
If your battery health is fine, you can use your battery settings to find out if an app is using too much power. You can also try some of these tips to max out your iPhone’s battery. They’re pretty easy things to do, and your battery life might improve.
