How to fix iPhone battery life problems

There could be a number of reasons that your iPhone’s battery is giving you trouble. It could be the result of some intensive process, and you just need to wait it out. Or something more serious could be going on. In any case, here’s how you can handle iPhone battery life problems.

Step One: Wait for it

Whether you restore from backup or set up as new, your new iPhone or updated version of iOS 11 could expend up a lot of power downloading apps, games, mail, photos, and other content. That’s because the Wi-Fi radio stays on for a long time, and Spotlight — the iOS search system — has to index everything. Some apps rebuild their own libraries and databases as well. When radios and processors can’t sleep, power consumption goes way up.

If you’ve just upgraded to a new iPhone, updated to the latest version of iOS, or restored your iPhone, give things a day or so to finish up and go back to normal. If you’re fine after that, great. If not, keep reading!

In addition to the system taking a while to really finish transferring everything over, we also tend to spend a long time playing with new phones and new features. That’s especially true with things like Animoji, Portrait Lighting, and Augmented Reality (AR) apps. So the screen stays on, storage gets written to, WI-Fi and maybe cellular radios stay lit up, and power gets consumed.

In other words, if your battery feels like it’s only lasting half as long, the first step to fixing it is figuring out if you’re using it twice as much.

So, note down how much battery life you have left. Then put your iPhone down for 20-40 minutes. When you pick it back up, note down how much battery life you have left again. If there isn’t a big change while in standby, you’re probably okay, and your battery life will return to normal when your usage returns to normal (after the novelty wears off).

If your iPhone continued to drain and drain fast, even when you weren’t using it, keep reading!

How to reset your iPhone

Rebooting, restarting, or resetting is the oldest cliche in troubleshooting. Because it works. Sometimes a good reset is all that’s needed to kick bad bits loose.

iPhone 8 and later require different button combos than previous iPhones:

  1. Quickly click and release the Volume Up button.
  2. Quickly click and release the Volume Down button.
  3. Press and hold the Side button (sleep/wake, on/off).

So does iPhone 7:

  1. Press and hold down the On/Off button on the right side
  2. While continuing to hold the On/Off button, press and hold the volume down button on the left side of your iPhone.
  3. Hold both buttons as the screen turns off, and keep holding them until the screen turns back on and displays the Apple logo.

For iPhone 6 and previous iPhones:

  1. Press and hold down both the Sleep/Wake button and the Home button at the same time.
  2. Keep them held down until you see an Apple logo.
  3. Let go.

On iPhone SE, and iPhone 5s and previous iPhones, the power button is located on the top:

Once your iPhone has rebooted, repeat the previous steps and see if battery drain has returned to normal. If not, keep reading!

How to check your iPhone’s battery usage

iOS contains a terrific battery usage — aka battery shaming — utility that lets you know exactly which apps and services are using your battery and how.

  1. Launch Settings from your Home screen.
  2. Tap on Battery. Wait a moment for Battery Usage to populate.

  3. Tap on the Show Activity button to get a breakdown of foreground and background power usage.
  4. Tap on Last 10 Days to get a broader look at power consumption over time.

It can be tricky to understand, but here’s the deal: If you see iCloud Photo Library there, and you’ve just upgraded, it’s a sign you’re downloading thumbnails and things should return to normal when you’re done. If you see Facebook there and it says 4% on screen and 40% on background, it’s a sign something has gone wrong.

At that point, you can force quit a rogue app and likely get your power consumption back to normal.

  1. Double click the Home button to bring up the fast app switcher.
  2. Swipe to the app you want to force quit.
  3. Touch the app card and flick it up and off the screen

On the iPhone X and later, you can force quit an app like this:

  1. Swipe up from the bottom of the screen and hold your finger in place for a moment until the card-like multitasking interface appears.
  2. Swipe to the app you want to force quit.
  3. Flick the app card up.

If an app appears to be consistently misbehaving, you can try re-installing it or even switching to an alternative app or a service’s website for some of your activity.

How to check your iPhone’s battery health

With iOS 11.3, Apple added Battery Health information. It reveals the current maximum capacity and peak performance capability, and will also inform you if your iPhone is being slowed down, whether it needs service, and will even allow you to turn off advanced power management — now called performance management — if you so choose.

  1. Tap on Battery in the Settings app.
  2. Tap on Battery Health.

If your iPhone had been slowed down due to prevent an unexpected shutdown, iOS will restore it to its previous, unmanaged performance levels. Performance management will only kick back in when and if you experience another unexpected shutdown. Until then, it’s a clean slate.

It’s worth noting what the percentages you see on the Battery Health screen actually mean. At 100% health, your batter should experience peak performance. When Battery Health is at 95%, that means that your iPhone has experienced a shutdown, and Performance management has now been applied. If your phone’s battery health is at 79% or less, it has been significantly degraded. At this point, you should probably take your iPhone to an Apple Authorized Service Provider for replacement.

How to restore your iPhone as new

Sometimes restoring from an old backup, especially a backup of a different device like an iPad, can be less than ideal. Cruft builds up and things just don’t run like they used to. Sometimes your once-fresh setup also goes stale.

If you suspect that’s the case, you can suck it up and set up your iPhone as new. Yes, it can be an incredible pain in the apps, but if you have a significant and continual problem, and nothing else can fix it, setting up as new can be a solution. First, you’ll need to erase your iPhone.

  1. Tap General in the Settings app.
  2. Tap Reset.

  3. Tap Erase All Content and Settings.
  4. Tap Erase Now since you’re going to be restoring your iPhone as new.

After you’ve nuked your device back to the Stone Age, you’re going to need to set it up as a new device, rather than transferring your data back to your device.

How to turn on Low Power Mode

  1. Launch the Settings app from the Home screen.
  2. Tap Battery.
  3. Toggle Low Power Mode to on.

Apple Smart Battery Case (2019)

Apple’s latest Smart Battery Case packs wireless charging.

The most recent generation of the Smart Battery Case features models for Apple’s three 2018 iPhones. In addition to greatly extending the battery life, the new Smart Battery Case supports wireless charging.

Like the older version of the case, the new Smart Battery Case intelligently manages power to give your iPhone the maximum amount of battery life. This time around, Apple added a case for the larger iPhone XS Max, as well as the iPhone XR. The wireless charging works for both the case and the iPhone, as the case will charge wirelessly without the phone inside it, and if the phone is inside, the case will charge the iPhone while being wirelessly charged itself.
