While many people upgraded to Apple's iOS 10 update, others stayed on the company's iOS 9 operating system. Some by choice, others by force. The original iPhone 4s and iPad mini did not receive iOS 10 updates.

iOS 9 battery life issues continue to frustrate many iPhone and iPad users, including those on the latest final version of iOS 9, Apple's iOS 9.3.5 update . It's not surprising. Abnormal battery drain is a common iOS problem.


iOS updates aren't supposed to have a negative effect on overall battery life on the iPhone, iPad, and iPod touch, but we're still seeing complaints.

In the case of iOS 9, these complaints come more than a year after its release on iPhone, iPad and iPod touch.

You should keep some of these tips and fixes stored in your memory bank. Battery life issues can hit your device at any time, so you'll always want to be prepared.

Look in your apps

If you notice a strange battery drain on your iPhone, iPad, or iPod touch, the first thing you'll want to do is take a close look at your apps, especially if you're playing Pokemon Go.

It's easy to blame Apple for your problems, but chances are it's a third-party app hogging your resources.

To start digging into your app's performance, you'll want to head into Settings > Battery and familiarize yourself with the Battery Usage Tool and the changes Apple made in iOS 9.

The tool will show you which apps are consuming the most battery, but it will now show you when they are consuming the most battery.

It will also show you which apps used the most power over a 24-hour period and what consumed your phone or tablet's battery life over a longer period.

If you tap on the little clock there, you'll also be able to bring up a breakdown that tells you exactly when they're consuming the most battery.


Some apps drain the battery the most when the screen is on, and some can zap your power when the screen is off.

If you see anything odd, you'll want to try updating the app first (assuming it has good reviews). Developers have been rolling out iOS 9 support updates in the past few days and chances are your apps will have updates.

If that doesn't help, try reinstalling or completely uninstalling it to see if the overall battery life of your iPhone or iPad improves.

Facebook's app is again being criticized for causing battery life issues on the iPhone. A recent piece from The Guardian suggests that the app still consumes a substantial amount of battery life. The author claims that on average he has 15% more battery life every day without Facebook installed.

If you have the Facebook app on your phone, it might be worth uninstalling it (permanently or temporarily, it's up to you) to see if it has a positive effect on charging your iPhone.

If you play Pokemon Go on your iPhone, iPad, or iPod touch for long periods of time, chances are it will drain your battery.

Pokemon Go relies on GPS to track your movements. GPS kills battery life. Luckily, there are a few things you can do to combat Pokemon Go battery drain on iOS 9:

Start using low power mode

iOS 9 comes with a brand new feature that will help save your iPhone battery when you need it most.

iOS-9-Low Power

iOS 9's new Low Power Mode allows users to dramatically extend the remaining 10-20% of battery life without manually flipping a bunch of switches.

Just go to Settings > Battery > Low Power Mode > On and iPhone will limit many things you had to control manually. This can add several hours of actual use to your iPhone.

With iOS 9.3.5 on board, you will be able to use Low Power Mode with the Night Shift feature of iOS 9.3.

Activate airplane mode

If you're noticing the battery draining, it may be because you're in an area with spotty cell service. If so, your device will be working very hard trying to find a signal, which could cause your battery life to drain quickly.

To combat this, switch your device to low power mode or airplane mode. Airplane mode is at the top of the settings and it will kill all your connections. If you've flown in the past five years, you've probably used it.

When Airplane Mode is on, your phone will not search for a better signal or nearby connection. Just be sure to turn it off when you're back in an area with better service.

Disable iCloud Keychain

This is a potential fix that has been passed around over the years and 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 an increase in battery life after turning it off and you may see improvements.

To turn off iCloud Keychain on your device, you will need to go to Settings > iCloud > Keychain > Turn off iCloud Keychain. You can always turn the feature back on if you determine there is no connection between it and your device's battery drain.

Limit background app refresh

If you don't need your apps to automatically refresh in the background, you can try disabling the background app refresh feature that comes standard with iOS.

Background app refresh is handy if you want your apps to show the latest data every time you open them, but in our experience it's proven to be a a heavy consumer of resources. If you have it enabled, apps will run in the background and this can be a catalyst for poor battery life.

iOS 9 midnight version

Go to Settings > General > Background App Refresh > Disable it for each app that uses too much power. It's a tedious process, but it might help.

You can also completely disable the feature if you don't want to go through your list of apps one by one.

Manage your display

Get a handle on your screen.

Apple's iPhone, iPad and iPod touch use a range of sensors and one of these sensors automatically adjusts the screen in certain lighting environments. Sometimes the sensor works just fine. Sometimes that's not the case.

If you notice strange iOS 9 battery drain, try disabling Auto-Brightness. To do this, go to Settings > Display & Brightness > Auto-Brightness > Off. Once off, you will need to manually adjust the screen brightness.

iOS 9's Control Center offers quick access to an automatic 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 slide to turn off the device. Hold down the power button again to restart the device.

If that doesn't help, you can also try a hard reset. To do this, press and hold the home button and the power button for about 10 seconds. The device will restart on its own. As a reminder, this will not delete any of your data.

Reset all settings

The fixes above include changes to your habits and some minor tweaks. The fixes listed below are more drastic measures.


The first step to follow is a reset of all settings on your device. To do this, go to Settings > General > Reset > Reset All Settings, then enter your password when prompted.

The reset process can take about five minutes and once complete, it will restore your settings to their default values.

You'll also want to have your various Wi-Fi passwords handy. Once this process is complete, your phone or tablet will have forgotten these passwords.

Bring your device

If nothing works here, it's time to take your iPhone or iPad to an Apple Store to have a Genius run some diagnostics.

You might have a swollen battery, you might have something else. If your device is still under warranty, they might even offer you a replacement.

Talk to Apple Support online

If none of these fixes work and you don't want to move from your desk chair, you can ask Apple for help online.

If you're having trouble with iOS 9 battery life, try contacting Apple's Twitter Support Line for help. It is possible that they have a fix or two that are not in this list.

Download iOS 10

If nothing works, you can try upgrading to iOS 10 update if your device is eligible. iOS 10 users are also complaining about battery drain issues but it might improve your device performance.
