Some iPhone 8 and iPhone 8 Plus users are running into battery life issues. If you start to notice abnormal battery drain on your iPhone 8 try a fix from this guide before taking scheduling an appointment at your local Apple Store.
Apple’s iPhone 8 and iPhone 8 Plus are still two of the best smartphones money can buy, but they aren’t perfect. iPhone 8 users are running into a myriad of problems including weird battery drain.
Some iPhone 8 users are noticing rapid battery loss in situations where the battery shouldn’t be taking a significant hit. In some cases this may be related to a bad battery. In most cases though, it’s an app gone rogue or simply bad habits from the person behind the wheel.
We expect Apple to roll out frequent iOS 13 maintenance updates but there’s no telling how long you’ll have to wait for the next upgrade. While you wait, you should try and fix these bad battery life issues yourself.
This guide will take you through some potential fixes and some tips that will help if and when you start noticing weird drain on your iPhone 8 or iPhone 8 Plus.
- 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%.
Restart Your iPhone 8
Sometimes all it takes is a simple restart. If you start to notice odd battery drain on your iPhone 8 or iPhone 8 Plus, hold down the power button and power the device down.
Use Low Power Mode
Your iPhone 8 comes with an extremely useful battery saving function called Low Power Mode. Low Power Mode minimizes animations (you can also do this manually) and optimizes your devices performance. Services like AirDrop and iCloud Sync will be disabled, but you can still make phone calls, receive texts, etc. You can turn Low Power Mode on whenever you want.
To enable Low Power Mode:
- Head into your iPhone 8’s Settings.
- Tap Battery.
- Tap Low Power Mode
- Toggle it on whenever you want to save a few battery percentage points and don’t want to turn Airplane Mode on.
You can also put a shortcut to Low Power Mode into Control Center (the menu that pops up when you swipe up from the bottom of your display) for easy access to the toggle.
To do that:
- Head to Settings.
- Tap Control Center.
- Tap Customize Controls.
- Tap the green plus sign next to Low Power Mode.
Use Airplane Mode
If you’re in a terrible service area your phone will struggle to pull down a signal. When your phone is working like that, your battery is probably dropping.
When you are in a spotty area flip on Airplane Mode from Control Center or the Settings app. This will disable all of your connections including Bluetooth, Wi-Fi, and cellular data.
Check Your Apps
There’s a very good chance your iPhone 8’s battery drain issue is related to an application on your device. If you haven’t done so already, you’ll want to investigate your apps.
Applications like Facebook are known battery hogs. They’ll eat up your device’s battery when in use and when they’re working in the background. It’s important to keep tabs on your apps and you can do that from a very simple menu located in your iPhone 8’s settings.
Go into your Settings, tap Battery and take a look at the Battery Usage tool. The tool shows you the apps doing the most damage to your iPhone 8 or iPhone 8 Plus’ battery life.
If you notice something out of the ordinary, check for an update on the App Store. Developers have been rolling out iOS 13 support updates and the recent bug fixes could help improve performance.
If it continues to struggle, you might want to delete the app. You can always re-install an app once you determine it’s not at fault.
Manage Your TrueTone Display
The iPhone 8 comes with a beautiful True Tone Display. While gorgeous, the display can do some serious damage to your battery life if you aren’t careful.
If you’d rather not have to deal with managing your display , you can turn on Auto Brightness. Your iPhone 8’s sensors will do all the work and adjust your display based on your lighting conditions.
Sometimes the sensors don’t work right and the device will light up, or dim, in situations where it shouldn’t. If your screen is bright for no reason you’re going to lose some battery.
Try manually adjusting your display to suit your lighting conditions. To do this, you’ll need to turn Auto Brightness off.
To do this:
- Go into Settings.
- Tap General.
- Tap Accessibility.
- Tap Display Accommodations.
- Go to Auto-Brightness and toggle it Off.
Once you’ve shut it off, you’ll need to manually adjust your screen brightness. This is extremely easy on the iPhone 8 or iPhone 8 Plus.
Simply pull up Control Center (swipe up from the bottom of your phone) and adjust the screen as needed. You can also adjust it in the Settings app.
Avoid Extreme Temperatures
Apple recommends avoiding extreme temperatures. Your device is is designed to operate normally between 62° to 72° F. If the temperature exceeds that you might notice some abnormal battery fluctuation.
The company says ambient temperatures that are higher than 95° F can permanently damage your iPhone’s battery capacity. Charging your iPhone 8 in high ambient temperatures can do further damage.
Apple also says iPhones operating in extremely cold environments may exhibit decreased battery life.
Turn Off Location Services
Location services like GPS can wreck havoc on battery life. If you’ve used Waze or Google Maps you probably know what we’re talking about. Fortunately, you have a lot of control over the services actively running on your device.
To do this, head into Settings and tap Privacy. At the top you’ll see Location Services. Tap it. You can shut them off entirely if you toggle it off but we recommend going through your apps to determine what apps should be using your services and when.
If an app you barely use is working in the background you’ll want to limit its capabilities. To do that, tap on the app in question and select Never.
Stop Using Live Wallpapers
Animated wallpapers look great on the iPhone 8’s display but they can and will drain the phone’s battery. If you want to save your battery use static backgrounds.
Remove Your Case While Charging
Charging your iPhone 8 or iPhone 8 Plus inside of certain cases could generate excess heat and that can affect your device’s battery capacity.
If you start to notice your iPhone getting hot inside of a case while it’s charging, take the case off and charge it naked.
Update Your Phone
If an update is available for your iPhone 8 or iPhone 8 Plus try upgrading. It might not list it in the change log but the update could improve your device’s battery life. Make sure you read reviews first.
Limit Your Notifications
If an app is frequently lighting up your phone’s display with notifications it’s probably draining the battery. Fortunately, you can turn these push notifications off.
Go into Settings and tap Notifications. Tap the app in question and set Allow Notifications to Off. If you have a lot of apps you’ll need to go down the list one-by-one.
When your iPhone 8 vibrates when you receive a phone call or a message it’s working. When your phone has to work it eats up power. If you don’t need vibrations going off every time you get a message, shut then off.
If you’re fine without vibrations go to Settings, tap Sounds, and toggle Vibrate on Ring and Vibrate on Silent off. You’ll also want to go into each individual Sound and Vibration and make sure Vibration (located at the top of the screen) is set to none.
Disable Raise to Wake
Your iPhone 8 comes with a nifty feature called Raise to Wake which wakes your phone up every time you pick it up. Turning it off could save you some percentage points.
If you’re fine manually turning your phone on every time you pick it up, head into the Settings app, tap Display & Brightness and toggle the Raise to Wake function off.
Reset All Settings
If none of those work, try resetting your Settings.
To do this:
- Go to Settings.
- Tap General.
- Tap Reset.
- Tap Reset All Settings
- Enter your passcode if you’ve got one.
The process could take a few minutes and it will restore your device’s settings to their factory defaults so make sure you have all of your Wi-Fi passwords handy. Your device will forget them.
Buy a Battery Case or Battery Bank
If you’re willing to spend a little money you might want to pickup a battery case or battery bank for some extra juice.
If you don’t want to cover up the iPhone 8’s beautiful design with a bulky case you might want to buy a battery bank.
Battery banks are small and lightweight gadgets that give you multiple charges. For instance, the RAVPower battery pack can give you six full iPhone charges.
Install iOS 13.5.1 for Better Security
If security is important to you, think about installing the iOS 13.5.1 update.
iOS 13.5.1 brings one security to iOS 13-powered iPhone models which you can read about on Apple's website. The patch is for an exploit used by jailbreak developers.
If you skipped iOS 13.5, iOS 13.5.1 brings iOS 13.5's 41 new security patches with it. Apple's posted the details on its website and you can dig into the particulars if you're interested.
Among them, patches for the company's Mail app, Wi-Fi, AirDrop, Bluetooth, FaceTime, Messages, and Notifications.
If you skipped the iOS 13.4 update, you'll get iOS 13.4's 28 security patches with your upgrade. You can read about all of them on Apple's website right here.
iOS 13.4 also brought several improvements to Apple's Intelligent Tracking Prevention. Apple's John Wilander outlined them in a blog post and it's worth checking out.
Reports have outlined a vulnerability in Wi-Fi chips made by Broadcom and Cypress Semiconductor that left billions of devices susceptible to attack.
Dubbed Kr00k, the vulnerability allows nearby attackers to decrypt sensitive information that's relayed over-the-air.
Fortunately, it looks like the issue was patched up with the release of iOS 13.2, an update that arrived all the way back in October.
So if you're running a really old version of iOS 13, you'll really want to move your device up to the newest version of iOS 13.
If you skipped iOS 13.3.1, you get its patches with iOS 13.5.1.
The iOS 13.3.1 update included 21 new security patches that will help protect your device from harm. The company's outlined those patches in detail if you want to dig in.
If you skipped iOS 13.3, you get its patches with iOS 13.5.1. iOS 13.3 brought 12 new security patches to the iPhone and you can read about each one over on Apple's security page.
The iOS 13.3 update also added support for NFC, USB, and Lightning FIDO2-compliant security keys in the Safari browser.
If you missed iOS 13.2, it had 16 new security patches on board. You can read about all of them on Apple's website right here.
iOS 13.1.1 brought a security patch for a third-party keyboard issue to your iPhone. If you're interested in the particulars, you can read about them over on Apple's website.
If you passed on installing iOS 13.1, you get an additional patch with your iOS 13.5.1 update. You can learn more right here.
If you're moving up from iOS 12, you'll get iOS 13.0's nine security patches with your upgrade to iOS 13.5.1. Read about those here.
If you skipped iOS 12.4.1 or any older versions of iOS 12, you'll get their security patches with your iOS 13.5.1 update.
iOS 12.4.1 only had one patch on board, but Apple's iOS 12.4 update brought 19 security patches to the iPhone. If you're interested in the specifics, you can read about them on right here.
In addition to those patches, iOS 13 itself comes with some security and privacy upgrades including improved anti-tracking features in Safari and the ability to get rid of location metadata in your photos.
You also now have the ability to block apps from using Bluetooth and the ability to allow apps to access your location just once.
iOS 13 will also send you reminders about applications that track your data.
