iPhone 7 battery life problems continue to popup for users and today we want to show you how to fix bad iPhone 7 battery life on the 4.7-inch model and the iPhone 7 Plus.
In September, Apple confirmed the iPhone 7 and iPhone 7 Plus, the successors for the iPhone 6s and iPhone 6s Plus. The two devices come loaded with features including improved cameras, a new home button, and more.
The iPhone 7 and iPhone 7 Plus received solid reviews but they’re far from perfect. We’ve already heard about a number of issues plaguing the two flagships. 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.
How to Fix Bad iPhone 7 Battery Life
This guide will show you how to fix bad iPhone 7 battery life and it will help prepare you for the future. Abnormal battery drain can emerge at any time so you’ll want to be ready for it.
These fixes will work if you’re on an iPhone 7 or iPhone 7 Plus and they’ll work on any version of Apple’s iOS 10 operating system.
Here are a few things to try if you’re experiencing iPhone 7 battery life problems.
Wait A Few Days
If you just opened your iPhone 7 or iPhone 7 Plus or installed a new iOS 10 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 into the problem.
Note that this can also happen after you install a new iOS update. Keep that in mind for future iPhone 7 iOS updates.
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, you’ll want to 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.
You can toggle it on and off anytime.
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 10 support updates and these updates should help squash bugs. They’ll also deliver new features to your iPhone 7.
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.
The iOS 10 operating system on your phone makes this extremely 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.
Restart the iPhone 7
A simple restart could dislodge your iPhone 7 battery life woes.
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.
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.
If that doesn’t work, you could try downgrading to the previous versions of iOS if a downgrade is available.
Dropping down to an older version of iOS 10 won’t guarantee success but there’s a chance an older version will improve performance.
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:
- Plug in and backup to the computer or to iCloud.
- Turn off Find My iPhone – Settings -> iCloud -> Find my iPhone -> Off.
- In iTunes Click Restore.
- Follow the prompts and the iPhone will reinstall iOS 10 from scratch.
- 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. A long time ago we took an iPhone 5s in and discovered a bloated battery was responsible for the battery drain.
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.
Install iOS 11.2.1 If You Use HomeKit
Apple's iOS 11.2 update fixed several problems, but it also brought some 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.
Last week, Apple rolled out a server-side fix, but the company's restored full functionality with the release of iOS 11.2.1.
If you use HomeKit and value your home security, you'll want to install the iOS 11.2.1 update right away.
