How to Fix Bad iPhone 7 Battery Life

iPhone 7 battery life problems continue to popup for many users and today we want to show you how to fix bad iPhone 7 battery life on the 4.7-inch model and the larger iPhone 7 Plus.

The iPhone 7 and iPhone 7 Plus are excellent devices, but they’re far from perfect. We continue to hear about a variety of problems plaguing the two flagships as we push deeper into 2018. Problems include broken Wi-Fi, busted Bluetooth, and abnormal battery drain.

iPhone 7 and iPhone 7 Plus battery life will vary from person to person but if you’re sure your device is draining faster than normal, you’ll want to take action.

While your first instinct might be to head down to a local Apple Store for diagnostic tests, you might be able to fix your bad iPhone 7 battery life from home.

There are a number of potential fixes out there and today we want to run down some tips and fixes that’ve worked well for us, and others in the past.

Restart Your iPhone 7

A simple restart could improve your phone’s battery life.

If you haven’t turned your iPhone 7 off for awhile, try restarting it. This fix has worked for us and others in the past and it’ll only take a minute or so.

Wait A Few Days

If you just opened your iPhone 7 or iPhone 7 Plus or installed a new iOS update, and you start to notice weird battery drain, don’t be alarmed. This is normal and it could take a couple of days for your device to settle in.

If your iPhone 7 or iPhone 7 Plus is still exhibiting abnormal battery drain after two days it’s time to dig a little bit further.

Use Low Power Mode

Your iPhone 7 comes equipped with a a feature called Low Power Mode and it will allow you to stretch out the last 10-20% of your iPhone 7’s battery life without killing off core services. If you’re experiencing abnormal drain or if you simply want to save some battery life, start using this feature.

If your iPhone dips into the 10-20% battery mark, you should get a prompt that asks you if you want to turn it on.

You can also manually turn it on in your iPhone 7’s settings if you think you need it before that. Go to Settings > Battery > Toggle Low Power Mode on.

If you’re running iOS 11, you can add Low Power Mode to Control Center. Head to Settings > Control Center > Customize Controls and tap the green plus sign next to Low Power Mode.

Use Airplane Mode When You Have Bad Service

When you’re in a bad service area your iPhone 7 will extremely hard to pull down a signal. This can destroy your device’s battery. To offset this, you can do a few things.

If you’re fine with killing off all your services, you’ll want to toggle on Airplane Mode. Airplane Mode kills off all of your connections and it will help you conserve battery when you start noticing a huge drop.

To toggle Airplane Mode on, you can head right into your Settings. It’s right at the top. You can also access it from the Control Center. To access the Control Center, swipe up from the bottom of your iPhone 7 or iPhone 7 Plus.

Flip off Airplane Mode when you leave the bad service area.

Shut Off Location Services

Location services like GPS can wreck havoc on your iPhone 7’s battery life. If you’ve ever used Google Maps or Waze you know what we’re talking about.

To help conserve your device’s battery life, you’ll want to get a handle on what services are active on your iPhone 7.

To do this, head into Settings > Privacy. You can turn Location Services off completely with a toggle off but we recommend going through your apps to determine what apps should be using your services and when.

If there’s an app you barely use working in the background you’ll want to limit its capabilities. You can do that with a simple toggle.

Check Your Apps

You’ll also want to get a handle on your applications. If you use an app a lot, it’ll suck up your battery life. But if you’re confident it’s using up more battery than it should, you’ll want to dig in.

First, you’ll want to head into your Settings and locate the Battery Usage tool. It’s located in Settings > Battery. It’ll show up under the Battery Usage header. This tool will show you the apps eating up your iPhone 7’s battery.

If something seems off about an app, you’ll want to act.

The first thing to do is look for a bug fix update. Apple’s developers have been rolling out a steady stream of iOS 11 support updates and these updates should help squash bugs. They’ll also deliver new features to your iPhone 7 or iPhone 7 Plus.

If a bug fix update doesn’t help, you can try reinstalling the application. You can also try uninstalling the app to see if that nets you positive results.

The Facebook app is known to be a problem so if you’re a heavy Facebook user you’ll want to weigh your options.

Turn Off Push When You Can

The iPhone 7’s push feature for notifications, email, and calendar can suck up battery life. If you don’t need push, you might consider turning it off to see if that helps your cause.

You’ll find your Push Notification settings in Settings > Notifications. Once you’re there you can turn off push for the applications you don’t use and even some that you do use if you decide you don’t need the feature.

Consider switching Mail, Contacts and Calendar to Fetch instead of Push. To do that, go into Settings > Mail, Contacts, Calendars and turn off Push.

Manage the iPhone 7 Display

Your iPhone 7’s display can and will eat up battery life if you don’t manage it properly.

The iPhone’s auto brightness feature can be useful but there are times where it fails to work properly. And when that happens you will lose precious battery life. So if you start to notice abnormal drain, you might want to get a handle on your screen.

iOS 11 makes it easy. Simply pull up from the bottom of the screen to enter Control Center.

From there, just use the screen toggle to adjust your screen brightness. If you don’t need the screen to be bright, keep it low. You’ll conserve battery that way.

If you’d rather adjust the screen brightness in your settings head to Settings > Display & Brightness to adjust.

Reset All Settings

If none of the above works, it’s time to take some bigger steps to help solve your iPhone 7 battery life problems.

The first step we recommend is a reset on all of your iPhone 7’s settings. To do this, go to Settings > General > Reset > Reset All Settings and then enter your passcode when prompted. If you don’t have a passcode it obviously won’t prompt you.

This process could take a few minutes and it will force your device to forget your connections (and passwords) but it might resolve your battery life issues. It won’t delete any files.

Update

If you’re running an older version of iOS 11 on your iPhone 7 or iPhone 7 Plus, try upgrading to iOS 11.4.1. We’re having an excellent experience on Apple’s latest version of iOS 11 and there’s a chance it’ll help your device’s performance.

Downgrade

If that doesn’t work, you could try downgrading your iPhone 7 or iPhone 7 Plus to the previous versions of iOS if a downgrade is available.

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

Restore from a Backup

If none of that works, you can try restoring from a backup or wiping your iPhone 7/iPhone 7 Plus completely. This should only be used as a last resort because it’s extremely time consuming.

Here’s how to do this:

  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 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.

Again, you should only do this if nothing else works.

Take Your iPhone 7 Into an Apple Store

If you don’t want to restore or perform a factory reset, you can also make an appointment to go see an Apple Genius at the Apple Store. Geniuses will be able to run some diagnostics on your phone and they could help you figure out the problem.

If you’re under warranty, and you are right now, you might be able to get another iPhone 7 or iPhone 7 Plus for free.

4 Reasons Not to Install iOS 11.4.1 & 8 Reasons You Should

Install iOS 11.4.1 for Better Security

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 skipped iOS 11.2.5, you'll get 10 additional security patches including one for the malicious chaiOS link exploit.

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.

If you're on iOS 11.2.1, your iOS 11.4.1 update includes security improvements to Safari and WebKit to mitigate the effects of Spectre.

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.

Apple's first iOS 11 update delivered several patches for potential exploits. iOS 11 also comes with new security features aimed at keeping your data safe.

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.

    I’m so tired of Apple advertising new phones with better batteries, new features, brighter displays, bigger cameras, but in order to get to the end of the day, please turn off notifications, location services, brightness, vibration, reduce use of video and camera, and you know what? Why getting a phone if you can’t use it?

    I think you guys should tell readers to do a complete backup of their information before you tell them to delete/restore settings . I may have missed that part in the article but I didn’t see any disclaimer . It would be devastating if somebody didn’t have a backup and followed the reset advice in this article thus losing all of their content .
