    How to Fix Bad iOS 12 Battery Life

    How to Fix Bad iOS 12 Battery Life is a post by Adam Mills from Gotta Be Mobile.

    Some iOS 12 users are reporting abnormal battery drain after installing the latest firmware. Fortunately, most battery issues can be solved in a matter of minutes.

    iOS 12.5 users are complaining about an issue where their device appears to be losing power faster than normal.

    There’s a chance some people are dealing with bad hardware, but there’s a very good chance bad habits or rogue apps are the ones to blame.

    If you’re dealing with horrendous battery life your instincts might compel you make an appointment to see an Apple Genius at your local Apple Store. This is certainly an option, but you’ll want to try and fix your issues before you go that far.

    This guide to bad iOS 12 battery life on iPhone, iPad and iPod touch will provide you fixes we and many others have discovered and used over the years. It also contains some strategies you should use to prevent battery life issues from happening again.

    Some of these steps can be done in seconds, others might take you a lot longer. All of them have the potential to fix your issues.

    Restart Your Device

    If you start noticing bad battery life after installing iOS 12 the first thing you’ll want to do is restart the device. Power it down, wait 20-30 seconds, and then power it back on and check to see if performance has improved.

    Update Your Phone

    If you’re struggling, think about upgrading your device to the latest version of iOS 12.

    Apple almost never touts battery life improvements in iOS change logs, but there’s always a chance new software straightens your performance out.

    Make sure you read reviews and dig into feedback before you install a new version of iOS 12.

    If you’re using an iPhone 6s or newer, and you’re still running iOS 12, you should consider upgrading to iOS 14. iOS 14 comes with a number of performance enhancements and could do wonders for your phone’s performance.

    Apple iPhone 11 Pro Max, 256GB, Midnight Green, Fully Unlocked (Renewed)

    • Fully unlocked and compatible with any carrier of choice (e.g. AT&T, T-Mobile, Sprint, Verizon, US-Cellular, Cricket, Metro, etc.).
    • The device does not come with headphones or a SIM card. It does include a charger and charging cable that may be generic, in which case it will be UL or Mfi (Made for iPhone) Certified.
    • Inspected and guaranteed to have minimal cosmetic damage, which is not noticeable when the device is held at arms length.
    • Successfully passed a full diagnostic test which ensures like-new functionality and removal of any prior-user personal information.
    • Tested for battery health and guaranteed to have a minimum battery capacity of 80%.

    Downgrade

    For a limited time Apple will allow you to downgrade your device to the previous version of iOS. If your phone or tablet was getting good mileage out of the previous update, downgrading is worth a shot.

    For more on the downgrade process, please take a look at our guide.

    Use Screen Time

    iOS 12 comes with a Screen Time feature that could help you conserve battery while eliminating bad habits.

    Screen Time provides you with a new set of controls that can help keep your smartphone addictive behavior in check. If you aren’t on your phone as much you won’t be chewing up your battery.

    The feature lets you set limits on how long you can use a particular app on a given day. If you approach that threshold, it’ll give you a warning.

    You can also set these alerts for kids and link this to a ScreenTime Allowance. This allows you to set limits on games, but keep important apps for schoolwork available.

    Use Low Power Mode

    iOS 12’s Low Power Mode can help you conserve battery life by shutting off services that could drain your battery. These include Hey Siri, automatic downloads, and mail fetch.

    You can turn Low Power Mode on and off any time, but your device will prompt you to turn it on whenever your phone reaches 20% battery.

    We highly recommend adding Low Power Mode to your device’s Control Center. Control Center is the menu that pops up when you swipe up from the bottom of the screen.

    In order to do that you need to:

    • Head to Settings.
    • Tap Control Center.
    • Tap Customize Controls.
    • Tap the green plus sign next to Low Power Mode.

    The next time you open Control Center you’ll see a battery icon. Tap that on and off to enable or disable Low Power Mode.

    You can also turn Low Power Mode on via your Settings. To do this:

    • Go to Settings.
    • Tap Battery.
    • Tap Low Power Mode.
    • Toggle it On.

    Use Wi-Fi Instead of LTE

    Using your device while it’s connected to a cellular network (LTE, 4G) can chew through battery. That’s why you’ll want to connect your device to Wi-Fi whenever you can. Using Wi-FI uses less power which means more battery.

    Check & Monitor Your Apps

    Apps like Facebook are known resource hogs. Apps also can go berserk after Apple releases a new version of iOS so there’s a chance one or more of your apps is the culprit behind your sudden battery drain.

    If you haven’t already, you’ll want to head into your Settings to check out the apps draining your battery life the most. This could help you single out the app, or apps, causing your issues.

    Head into your Settings, tap Battery, and take a look at the Battery Usage tool. It will show you the apps doing the most damage to your device’s battery.

    If you notice an app draining a ton of battery in the background, try deleting the app to see if your battery life improves. You can always re-install the app if you determine it’s not the source of the problem.

    If you’d prefer to keep the app, try installing the latest bug fix update to see if that helps. Developers are rolling out iOS 12 support updates so a quick update could take care of your issues.

    Disable Vibrations

    If your device vibrates every time you receive a phone call or a message you should try turning vibrations off. These alerts can be useful, but they make the hardware inside your phone work and this type of work requires power.

    To shut off vibrations:

    • Go to Settings.
    • Tap Sounds.
    • Toggle Vibrate on Ring and Vibrate on Silent off.

    You’ll also need to go into each individual Sound and Vibration and make sure Vibration (located at the top of the screen) is set to none.

    Manage Your Display

    Your device’s display can be a battery killer if it’s not managed correctly.

    The sensors inside your iPhone or iPad will adjust the screen automatically in certain lighting environments. Sometimes these sensors work as intended. Sometimes they don’t. If your screen is bright for no reason, your phone could be draining power at a faster rate.

    Try manually adjusting your display to suit your lighting conditions. To do this, you’ll need to turn Auto Brightness off in your device’s Settings:

    • Go into Settings.
    • Tap General.
    • Tap Accessibility.
    • Tap Display Accommodations.
    • Tap Auto-Brightness.
    • Toggle it Off.

    Once you’ve shut it off, you’ll need to manually adjust your screen brightness. You can do that from Control Center or via the Settings app.

    Disable Raise to Wake

    Raise to Wake is handy, but turning it off could help you save a few battery percentage points.

    If you don’t need your screen to automatically turn on whenever you pickup your device, go into the Settings app > Display & Brightness and turn the Raise to Wake function off.

    Kill Background Refresh

    Apple’s Background App Refresh feature does exactly what its name implies: It refreshes apps in the background in order to show you the latest data when you open them up.

    A lot of people love the feature, but it can be a resource hog. If you don’t know think you need it, try turning it off. It could help you save battery.

    To disable it, you’ll need to:

    • Go to Settings.
    • Tap General.
    • Tap Background App Refresh.
    • Turn it off for any applications you don’t use.

    You can also turn Background App Refresh off completely if you don’t want to go through your list of apps one by one.

    Turn Off Fitness Tracking

    Your iPhone features a motion co-processor that can track your steps and other activities. If you’re using your phone to help stay in shape you’ll want to keep this feature on because it can be useful. If you don’t use your phone to track your fitness you should try turning the feature off.

    Head into your Settings app and tap on Privacy. From there, select Motion & Fitness and toggle the Fitness Tracking function off.  You might also want to toggle off any apps listed below Fitness Tracking in the menu.

    Use Airplane Mode

    If you start noticing rapid battery drain, you should turn on Airplane Mode.

    Airplane Mode, which can be accessed via the Settings app or Control Center, kills all of your connections including Wi-Fi, Cellular Data, and Bluetooth.

    If you’re in an area with bad service, your phone is probably working hard to get a signal. When your phone is working hard, your battery is probably draining.

    In cases like this, turn on Airplane Mode until you’re back in an area with good service.

    Turn Off Assistive Touch

    If you’re using Assistive Touch on your device there’s a chance it’s the reason your battery is draining abnormally.

    If you don’t need Assistive Touch active on your device, try turning it off. Here’s how to do this:

    • Go to Settings.
    • Tap General.
    • Tap Accessibility.
    • Tap AssistiveTouch.
    • Toggle it off.

    Reset All Settings

    Resetting your device’s settings could have a positive impact on your battery life.

    In order to reset your settings you need to:

    • Go to Settings.
    • Tap General.
    • Tap Reset.
    • Tap Reset All Settings.
    • Enter your passcode if you have one enabled.

    This process could take a few seconds to complete and it will restore your settings to their factory defaults so make sure you have your Wi-Fi passwords handy. It will cause your device to forget known connections.

    Restore as New

    If you’ve owned your device for awhile, you might try restoring the device from a backup. Or, if you’re feeling really ambitious, you can try restoring the device as new. You can do this via Finder, iTunes, or iCloud.
