Here’s everything you need to know about iPhone batteries and how long they last. 

How Long Does an iPhone Battery Last?

There are several iPhone models. Apple releases a new iPhone every year or so. With each new phone, there are upgrades. This sometimes includes a more powerful battery. This means that the battery capacity varies. 

These are the average battery lives for the most recent iPhone models. 

  • iPhone 7 and 7 Plus: 10-12 hours 
  • iPhone 8 and 8 Plus: 13 hours 
  • iPhone X: 21 hours talk time; 60 hours music 
  • iPhone XS Max: 10 hours 
  • iPhone XR: 11 hours 

Keep in mind that these are averages for new iPhones. Over time, the battery does not function at its full capacity. 

How to Preserve iPhone Battery

If you are away from a charger but need to use your iPhone, you can use low power mode. This is a setting that preserves your battery. It reduces the amount of power your iPhone uses. When your phone reaches 20%, you will get a notification asking if you want to turn low power mode on. 

You can also turn it off or on manually in your settings. 

When your iPhone is on low power mode, it impacts these features: 

  • Email fetch
  • “Hey Siri”
  • Background app refresh
  • Automatic downloads
  • Some visual effects
  • Auto-Lock (defaults to 30 seconds)
  • iCloud Photos (temporarily paused)

Then, once you charge your iPhone to 80%, low power mode will automatically turn off. 

You can also preserve your battery by keeping your brightness low. Figure out which apps might be using a lot of battery. Apps with location services on use a decent amount of battery. If you do not need to be using your iPhone, you can turn it off or put it on airplane mode. According to Digital Trends, turning down the volume helps. 

What is Using Up iPhone Battery?

You might think your battery is dying too quickly. You can see how much battery each app is using. First, go to settings. Then, click on battery. There will be a list of apps with percentages beside them. 

If an app is on the list and you haven’t been using it, it might be using your location. Some apps need your location. You have a choice on how that feature is used. You might say the app can use your location all the time. This is what might be draining your battery. In settings, you can go to location services. Then, you can choose which apps use your location. You can also choose how they use it. 

Some apps drain your battery. Pay attention to those apps and how often you’re using them. 

iPhone Charge Capacity

According to Apple, after 500 charge cycles, your battery will have a charge capacity of 80%. This means that when you charge your iPhone to 100%, it’s only charging to 80%.  

With more charge cycles, you are further decreasing that percentage. Your iPhone will continue to die more quickly. As a result, you will likely charge your iPhone more often. This only makes the problem worse.
