How to Fix Bad iOS 9 Battery Life

The iOS 9 update is finally here. And while it brings new features along with it, it’s also causing bad battery life problems. With those problems and new iOS 9.1 and iOS 9.2 beta battery life issues in mind, we show you how to fix bad iOS 9 battery life on iPhone, iPad and iPod touch.
In June, Apple confirmed an iOS 9 update, iOS 9 features, and an iOS 9 release date for the fall. As we pushed deeper into the summer, the iOS 9 update pushed closer to its release date and last week the company finally told iOS users when it would take it out of beta.
The iOS 9 update is here and it delivers some big time improvements to all devices capable of running iOS 8. That list includes devices like the iPhone 6 and iPhone 5s but also the iPhone 4s, the iPad 2, and the original iPad mini.
It’s a big update and it’s the first major iOS update since the iOS 8.4 update back in late June.

Apple’s iOS 9 update brings a ton of new features and fixes to the table but according to early adopters, it also brings some problems. Battery life issues also appear to be affecting those that have downloaded Apple’s brand new iOS 9.1 update.
This isn’t surprising. Abnormal battery drain is a common iOS problem and it always seems to show up, en masse, right after an iOS release.
Of course iOS updates, particularly big ones like iOS 9.1, aren’t supposed to have a negative effect on overall battery life on the iPhone, iPad and iPod touch. And with Apple touting an iOS 9 battery life boost, we’re not surprised people are frustrated.
While these iOS 9 battery issues are isolated, we expect them to grow as more people discover and download the iOS 9.1 update on their iPhone, iPad or iPod touch.

How to Fix Bad iOS 9 Battery Life

We want to help you solve your bad iOS 9 battery life issues ahead of the upcoming iOS 9.1 release date later this year.
This guide delivers help to get better battery life on all versions of the iPhone, iPad and iPod touch capable of running iOS 9, iOS 9.0.1, iOS 9.0.2, iOS 9.1, and the iOS 9.2 beta. Beta updates often cause severe battery drain.
You should keep some of these tips and fixes stored in your memory bank. Battery life problems can strike your device at any time so you’ll always want to be prepared.

Look Into Your Apps

If you’re noticing strange battery drain on your iPhone, iPad or iPod touch, the first thing you’ll want to do is take a long hard look at your applications. While you might want to blame Apple for your problems, there’s a good chance that it’s a third-party application hogging your resources.
To start digging into your app performance, you’ll want to go into Settings > Battery and get familiar with the Battery Usage tool and the changes that Apple’s made in iOS 9. The tool will show you which apps are eating up the most battery but it will now show you when they’re eating up the most battery.
The tool will show you what apps have been using the most power over a 24 hour span and it also shows you what’s been eating your phone or tablets battery life over a longer span of time. If you tap on the little clock there, you’ll also be able to pull up a breakdown that shows you exactly when they’re eating up the most battery.

Some apps will drain battery the most when the screen is on and some might zap your power when the screen is off.
If you see something odd, you’ll want to first try updating the application (assuming it has good reviews). Developers have been rolling out iOS 9 support updates in recent days and there’s a good chance your apps have updates.
If that doesn’t help, try reinstalling it or uninstalling it completely to see if your overall iPhone or iPad battery life improves some.

Start Using Low Power Mode

iOS 9 comes with a brand new feature that will help you conserve iPhone battery life when you need it most.
iOS-9-low-power
The new Low Power Mode in iOS 9 allows users to stretch out the last 10-20% of battery life significantly longer without flipping a bunch of switches manually.
Simply go to Settings > Battery > Low Power Mode > On and the iPhone will limit many items you used to need to control manually. This can add several hours of actual use to your iPhone.

Turn On Airplane Mode

If you’re noticing battery drain, it might be because you’re in an area with spotty cellular service. If you are, your device will work extra hard to try and find a signal and that could cause your battery life to start draining rapidly.
To combat this, flip your device into Low Power Mode or Airplane Mode. Airplane Mode can be found at the top of Settings and it will kill all of your connections. If you’ve flown any time in the past five years, you’ve probably used it.
With Airplane Mode turned on, your phone won’t be searching for a better signal or any nearby connections. Just make sure to flip it off when you’re back in an area with better service.

Disable iCloud Keychain

This is a potential fix that’s been passed down over the years and there’s a chance it might work for you after installing iOS 9.
Try disabling iCloud Keychain if you don’t use it. iPhone and iPad users have reported a bump to battery life after turning it off and there’s a chance you could see some improvements.
To disable iCloud Keychain on your device, you’ll need to go into Settings > iCloud > Keychain > Toggle iCloud Keychain off. You can always flip the feature back on if you determine that there’s no connection between it and the battery drain on your device.

Limit Background App Refresh

If you don’t need your apps to automatically refresh in the background, you might want to try disabling the Background App Refresh feature that comes standard with iOS.
Background app refresh is handy is you want your applications to show the latest data whenever you open them but in our experience its proven to be a resource hog. If you have it on, apps will work in the background and that can be a catalyst for bad battery life.

Go to Settings > General > Background App Refresh > Turn it off for each app that is using too much power. It’s a tedious process but it could help.
You can also turn the feature off completely if you don’t want to go through your list of applications one by one.

Manage Your Display

Get a handle on your display.
Apple’s iPhone, iPad and iPod touch use an array of sensors and one of those sensors adjusts the screen automatically in certain lighting environments. Sometimes the sensor works to perfection. Sometimes it doesn’t.
If you’re noticing strange iOS 9 battery drain, try shutting auto brightness off. To make this happen, go into Settings > Display & Brightness > Auto-Brightness > Off. Once it’s shut off, you’ll have to adjust the screen brightness manually.
iOS 9’s Control Center offers quick access to an auto brightness toggle. To pull it up, swipe up from the bottom of your screen.

Restart Your iPhone or iPad

You should also try restarting your iPhone, iPad or iPod touch.
If you don’t know how to do this, hold down the power button for a few seconds and swipe to shut the device down. Hold down the power button again to boot the device back up.
If that doesn’t help, you can also try a hard reset. To do that, hold down the home button and the power button for about 10 seconds. The device will restart it self. As a reminder, this will not remove any of your data.

Reset All Settings

The above fixes include changes to your habits and some smaller tweaks. The fixes listed below are more drastic measures.
iOS-9-Review-15
The first step to take is a reset on all of your device’s settings. To do this, go to Settings > General > Reset > Reset All Settings and then enter your passcode when the prompt appears.
The reset process could take five minutes or so and once it’s done, it will restore your settings to their factory defaults. Make sure you have Wi-Fi passwords handy because your phone or tablet will forget them. And as a reminder, this will not delete any of your files.

Downgrade to iOS 9.0.1

For a limited time, you can drop back down to iOS 9.0.2. To do that, take a look at our guide to downgrading.
This loophole won’t stay open forever so you’ll want to make your move sooner rather than later. Apple typically signs off on older updates for one to two weeks before pulling the cord.

Restore the iOS 9 Update

If none of this works, you can try a restore on your iPhone or iPad. This should only be used as a last resort because it erases everything on your device and could take awhile to complete depending on how many files you have on your device.
You can try restoring from your backup after the iOS 9 update. If your iOS 9 battery life issues return after the restore, you will want to try this method again without restoring from the backup. Here’s how to do this on an iPhone, iPad or iPod touch:
  1. Plug in and backup to the computer or to iCloud.
  2. Turn off Find My iPhone – Settings -> iCloud -> Find my iPhone -> Off.
  3. In iTunes Click Restore.
  4. Follow the prompts and the iPhone will reinstall iOS 9 from scratch.
  5. When it completes click Restore from Backup to put your information back on the iPhone or Choose to set up as a new iPhone.
This could take anywhere from 20 minutes to an hour to complete so make sure you set aside some time to do it in a quiet place without any distractions.

Take Your Device In

If nothing here works, it’s time to take your iPhone or iPad into an Apple Store to have a Genius run some diagnostics.
You could have a bloated battery, you could have something else. If your device is still under warranty, they might even offer you a replacement.
