What Kills Battery Health on iPhone?

As iPhones age, their battery health can start to deteriorate, causing them to run out of battery more quickly and require more frequent charging. While some battery degradation is inevitable, there are some things you can do to keep your iPhone’s battery healthy. Here, we’ll take a look at what kills battery health on an iPhone and how to avoid it.


Heat can be one of the most damaging factors to an iPhone’s battery health. iPhones are designed to work best in temperatures between 16 and 22 degrees Celsius, or 62 and 72 degrees Fahrenheit. If it gets too hot or cold, the battery won’t be able to hold a charge as well. To avoid this, make sure you keep your iPhone out of direct sunlight and away from extreme temperatures. It’s also important to not leave your iPhone in a hot car, as that can damage the battery.

Charging Habits

The way that you charge your iPhone can also have a big impact on battery health. It’s best to charge your iPhone when it’s at about 50%. This is because charging your iPhone all the way up to 100% every time can put a strain on the battery. Additionally, avoid leaving your iPhone plugged in for an extended period of time. This can cause the battery to overcharge, which can damage its overall health.

Apps and Services

Certain apps and services can also have a big impact on your iPhone’s battery health. Make sure to only use apps that you really need, as having too many apps running in the background can drain your battery. Additionally, try to limit the amount of time you spend using services like GPS and Bluetooth, as they can be big drains on battery life. If you’re not using them, make sure to turn them off.

Software Updates

Keeping your iPhone up to date with the latest software can have a big impact on its battery health. Every time a new version of iOS is released, it includes optimizations for battery life. Not only will this help keep your battery running better for longer, but it can also help to keep your iPhone secure and perform better overall.

Battery Cases

Using a battery case can be a great way to extend the battery life of your iPhone. However, it’s important to make sure that the case you’re using is specifically designed for your iPhone. Using a case that isn’t designed for your device can cause your iPhone to overheat, which can damage the battery. Additionally, make sure to take the case off when you’re not using it, as that can also cause the battery to overheat.

Replacement Batteries

If your iPhone’s battery is already damaged, you may be tempted to replace it with an aftermarket battery. However, this is not recommended, as these batteries can be of lower quality than the original and can also cause damage to your device. If you need a new battery, it’s best to go to an Apple Store or an authorized service provider.

Calibrating the Battery

One way to help keep your iPhone’s battery healthy is to periodically calibrate it. This is done by draining the battery all the way down until it turns off, and then charging it all the way up to 100% without using it. This helps to reset the battery’s “memory” and can help to keep it running better for longer.

Turning Off Unused Features

Your iPhone has a lot of features that you may not be using, such as location services and background app refresh. It’s a good idea to turn off any features that you’re not using, as this can help reduce battery drain. Additionally, if you’re not using certain apps, make sure to delete them from your device, as this can also help to save battery life.

There are several things that can kill battery health on an iPhone. Heat, charging habits, apps and services, software updates, battery cases, replacement batteries, calibrating the battery, and turning off unused features can all have a big impact on an iPhone’s battery life. Taking steps to avoid these issues can help keep your iPhone’s battery healthy for longer.
