Severe battery drain is just one of the problems plaguing iOS 11.4 beta testers. If you’re experiencing bad iOS 11.4 beta battery life and you don’t want to downgrade back to an older version of iOS 11, try one of the solutions below.
iOS 11.4 beta users are complaining about a number of problems including severe battery drain. This is a common iOS problem particularly on pre-release software that’s not quite ready for an official release to the public.
If you run into battery trouble, your first instinct might be to downgrade back to an older version of iOS 11. That’s certainly an option, but you’ll want to try and manually fix your issue before you resort to that.
This guide will provide you with some fixes and strategies to use if your iPhone, iPad or iPod touch battery life starts going haywire with the iOS 11.4 beta on board.
Some of these tips will only take you a couple of seconds to complete. Others are a little more involved. We recommend putting aside 15-20 minutes of quiet time to see what does, and doesn’t, work for you and your device.
Restart Your Device
If you start to notice severe battery drain on your device, try restarting your device. Hold down the power button, slide to turn it off. Power it back on.
Keep a Close Eye on Your Apps
Apps can be extremely buggy on iOS beta software and there’s a good chance one or more of your applications are causing your device to work harder than it should.
If your battery life is bad it’s time to launch an investigation in your applications. To do this, go into Settings > Battery and get acquainted with the Battery Usage tool. It will show you the apps eating up the most battery and when they’re doing so.
If you see something out of the ordinary, try deleting that app to see if your battery life improves. You can always re-install it if you determine it’s not the source of the drain.
If you’d prefer to keep the app, try installing the latest version to see if that helps. If you don’t have automatic updates turned on, head to the App Store on your iPhone or iPad and check for an update.
Widgets are all over the place in iOS 11. If you have a lot of widgets active, they could be sucking up your devices battery life. It’s time to get a handle on them.
Swipe to the right while you’re on your device’s home screen. Scroll all the way to bottom of your widgets and select Edit. It’s that circular icon.
You should now see a fairly long list of services and apps. These are your widgets. To deactivate a widget, tap the red circle with the white line and tap Remove.
First try disabling the widgets you never use. If you never use widgets, try disabling them all.
Use Low Power Mode & Put It In Control Center
iOS comes with a useful Low Power Mode that can help you conserve your battery without having to manually toggle off a bunch of your device’s functions.
To enable Low Power Mode on your device head into Settings > Battery > Low Power Mode > and toggle it On whenever you need it.
iOS 11 also allows you to put a shortcut to Low Power Mode in Control Center. Control Center is accessed via swipe up from the bottom of your device’s screen.
We recommend storing a shortcut in Control Center for easy access.
Use Airplane Mode When You Can
If you start seeing rapid battery drain, try putting the phone into Airplane Mode.
Airplane Mode, which can be accessed via your Settings app or in the Control Center, kills all of your connections including Bluetooth, cellular data, and Wi-Fi.
We always recommend using Airplane Mode when your device is in a spotty service area. This can cause your device to work extremely hard and your battery to drain abnormally.
Manage Your Display
Some iOS 11.4 beta users are reporting issues with the auto-brightness function. This might be a blessing in disguise for some of you.
The sensors inside the iPhone and iPad adjust the screen automatically in certain lighting environments. Sometimes these sensors work perfectly. Sometimes they’re off. If your screen is extremely bright for no reason, you might be costing yourself several battery percentage points.
We recommend turning Auto Brightness off, at least temporarily. Go into Settings > General > Accessibility > Display Accommodations >Auto-Brightness > Off. Once you shut it off, you’ll need to adjust your screen brightness manually. This is extremely easy in iOS 11.
Simply pull up Control Center and adjust the screen as needed.
Disable Raise to Wake
Disabling iOS 11’s Raise to Wake feature could also save you a few percentage points. If you don’t use it, try shutting it off.
To shut off Raise to Wake, go into the Settings app > Display & Brightness and toggle the Raise to Wake function off. You can turn it back on if the battery drain continues to plague your device.
Reset All Settings
If none of those tips help, try resetting your device’s settings.
To get started, go to Settings > General > Reset > Reset All Settings and then enter your passcode if one is enabled.
This process should take about three to five minutes and it will restore your device’s settings to the factory defaults. Make sure you have all of your Wi-Fi passwords handy because your device will forget all of them.
Buy a Battery Case or Battery Bank
If you’ve got some spare cash lying around, consider picking up a battery case or a battery bank for the duration of the iOS 11.4 beta or longer if necessary.
There are tons of battery case options out there and our list of the best iPhone cases will help you get started.
If you prefer not to put your device in a bulky case, you might opt for a battery bank.
Battery banks are small and lightweight and they can pack a huge punch. For instance, the RAVPower battery pack can give you six full iPhone charges.
Download the Latest Beta
If you’re running an old version of the iOS 11.4 beta try updating to the latest version when one is available for your device.
Upcoming iOS 11.4 betas will lingering issues and there’s a chance they’ll have a positive impact on your device’s overall battery life.
Install iOS 11.4.1 for Better Security
Apple's iOS 11.4.1 update comes with 15 patches for potential security issues. If you value your security, you should think about installing it today.
iOS 11.4.1 also comes with a USB Restricted Mode that disables the Lightning port on your iPhone or iPad if a device hasn't been unlocked or connected to a computer using a passcode within a certain amount of time.
The new setting is located in Settings > Face ID/Touch ID & Passcode. There you’ll see a new toggle for USB Accessories. It's toggled off by default.
This provides an added layer of protection and prevents the use of cracking tools like GrayKey.
If you skipped iOS 11.4, your iOS 11.4.1 update comes with 30+ patches aimed at improving your device's security. This makes it an essential download for most iPhone and iPad users.
If you missed any of Apple's previous iOS updates, your iOS 11.4.1 update comes with a lot more.
If you skipped iOS 11.3.1, your version of iOS 11.4.1 comes with iOS 11.3.1's four security patches.
If you skipped iOS 11.3, your iOS 11.4.1 update comes with 27 additional patches for potential exploits. Those of you lingering on iOS 11.2.6 would be wise to make the move sooner rather than later.
If you missed iOS 11.3, your iOS 11.4.1 update also includes a new privacy feature. When an Apple feature wants to use your personal information, an icon now appears with a link to access detailed information about how your data will be used and protected.
If you're running iOS 11.2.5 or older, you're currently exposed to an issue that lets people send a specific character that will crash an iOS-powered device and block access to the Messages app. It can also block apps like Facebook Messenger, Gmail, Outlook, and WhatsApp.
The iOS 11.2.6 update's main purpose was to patch up this issue. If you skipped iOS 11.2.6, you'll get these enhancements with iOS 11.4.1.
If you're running iOS 11.2.2 or below and receive a certain GitHub link through your Messages app, your iPhone or iPad can lockup or respring. The Messages app will also become unusable.
Apple's iOS 11.2 update fixed several problems, but it also brought problems of its own including a potentially nasty zero-day iOS HomeKit vulnerability.
The vulnerability, discovered by Tian Zhang, allowed for unauthorized control of HomeKit accessories including garage door openers and smart locks.
Apple quickly rolled out a server-side fix, but the company restored full functionality with the release of iOS 11.2.1. If you skipped iOS 11.2.1 and use HomeKit, you should download iOS 11.4.1 right now.
If you skipped iOS 11.2, you'll get a few more patches with your iOS 11.4.1 update. Apple's iOS 11.2 update delivered 11 patches including one for Mail and one for Wi-Fi.
The iOS 11.2 and iOS 11.2.1 updates also patched up a widespread security issue called "Meltdown." Apple says its analysis suggests it "has the most potential to be exploited."
Meltdown affects all iOS 11 powered devices so we highly recommend downloading iOS 11.4.1 if you skipped iOS 11.2.
If you skipped iOS 11.1.2, iOS 11.1.1, and iOS 11.1, you'll get additional patches with your iOS 11.4.1 update.
The iOS 11.1 update delivered eight security patches including a fix for a serious Wi-Fi vulnerability called KRACK or Key Reinstallation Attack. KRACK is an exploit that targets the common WPA2 encryption protocol.
If you're just now making to move from iOS 10 (or whatever you're on) to iOS 11, your iOS 11.4.1 update will come with even more security-related features.
In iOS 11 you can't establish trust with a PC using fingerprints alone. You'll also need to put in a full passcode in order to gain that trust.
If you want to protect the data you store on your iPhone, iPad, or iPod touch, you should make your move to the latest version of iOS. This is particularly important for those of you running older versions of iOS.
