How to Check Battery Usage on iPhone

Extensive use of an iPhone (or any other gadget for that matter) can deteriorate its battery over time and result in poor performance. Thankfully, Apple has a robust built-in Battery menu that lets you check the usage and tell which apps are draining your iPhone’s battery.

More often than not, a particular app is at fault. Read along to learn how you can check your device’s battery health. I’ve also thrown in some tips and busted some myths to help get the most out of your iPhone.

How to examine your iPhone’s battery usage

  1. Go to iPhone’s Settings.
  2. Scroll down and select Battery.
  3. After the loading is complete, you’ll see a breakdown of your battery level of the past 24 hours, what apps were in use, and which apps consume the most juice.

Understand your iPhone’s battery usage

The screenshot above shows that my iPhone’s screen was turned on for 6 hours and 27 minutes in the last 24 hours.

According to the charts, WhatsApp is the most battery-consuming app on my iPhone, eating around 37% of the battery. Tapping an app will also show you how much battery an app consumed while the screen was on and off (background activity).

Similarly, you can see the battery stats for the last ten days. It gives you an average estimate of how much battery an app consumes. Moreover, you can tap a particular area of a chart to see which app consumed battery during the select hours. Now, let’s dive deeper into your iPhone’s battery health.

Charging and discharging the battery reduces its retention over time, leading to its deterioration. Thus, it makes sense to stay ahead and check the battery health of your iPhone now and then.

Note: You can check battery health on iPhones running iOS 11.3 or later.

You’ll now see the maximum capacity of your iPhone’s battery. This is relative to when your iPhone was new. This section also shows the current performance level of your iPhone’s battery.

In my case, it shows maximum capacity as 100% and says that my iPhone supports peek performed capability, which is expected since it’s new. This might be different if your device is older. Apple says iPhones with maximum capacity above 80% don’t need a battery replacement.

If you happen to have an iPhone 11 series model, the chances are that the batter stats you might see in the Battery Health section might be wrong. Apple issued an update to rectify this. Here’s how to recalibrate your iPhone 11 battery in iOS 14.5. There’s also an option called Optimized Battery Charging if you have an iPhone running iOS 13 or later. Let’s learn more about it in brief.

What is optimized battery charging?

The Optimized Battery Charging, turned on automatically, charges your iPhone to 80% when it’s plugged in overnight, and completes the charge to 100% only when it’s the time for you to wake up. This prevents your iPhone from overcharging and keeps your iPhone’s battery healthy.

Busting myths surrounding iPhone’s battery life

Myths to check battery usage on iPhone

When it comes to battery and iPhone, you’ll find many myths floating around on the web. Don’t believe them, as they might hinder your iPhone experience. Here’re some to stay wary of.

  • Never use your iPhone while charging
    There’s no problem in using your iPhone while charging. Just make sure it isn’t too hot, which might take a toll on your iPhone’s battery health.
  • Charging an iPhone overnight can destroy its battery
    With new features like optimized charging, iPhone’s never fully charged until your wake-up time. There should be no problem charging an iPhone overnight, though leaving an iPhone plugged in the whole night can cause it to heat.
  • Closing apps save battery life
    iOS has evolved over the years and can easily handle multiple apps running side by side. Closing apps after using them won’t degrade your battery. On the other hand, starting apps again and again might consume more battery.
  • Dark Mode saves battery life
    Though easy on the eyes, the dark mode doesn’t save any battery on iPhones with LCD screens, like iPhone 8, iPhone SE, and iPhone 11. Since the pixels are still light, unlike with iPhones that have OLED screens, the dark mode doesn’t help with battery on older generation iPhones.
  • Let your battery drain completely before charging:
    With newer lithium-ion batteries, it doesn’t matter at what percentage you start charging your iPhone. However, you shouldn’t plug in your iPhone every time your battery hits 40%. Charging more causes your iPhone’s battery health to degrade, which limits its performance in turn.
