How to Fix Bad iPhone 6s Battery Life

The iPhone 6s and iPhone 6s Plus are excellent smartphones but they’re not perfect. iPhone 6s users continue to complain about abnormal battery drain and today we want to show you how to fix bad iPhone 6s battery life should you encounter on your device.

In 2015, Apple took the stage in San Francisco and announced a slew of new products. Among them, the iPhone 6s and iPhone 6s Plus, the two devices that took over flagship duties from 2014’s iPhone 6 and iPhone 6 Plus.

The iPhone 6s and iPhone 6s Plus come with some powerful features they’ve received excellent reviews though some continue to feel underwhelmed by their battery life.

Abnormal battery drain can appear at anytime though it typically rears its ugly ahead immediately after Apple releases a new iOS update.

In the months since their release, we’ve seen a number of iPhone 6s users complain about abnormal battery drain.

Fortunately there are some ways to get bad iPhone 6s battery life fixed without having to perform a factory reset or take a trip to an Apple Store.

How to Fix Bad iPhone 6s Battery Life

We want to help you fix your battery life issues and ensure that you’ll be ready if the problems suddenly return in the future.

These fixes will work if you’re on an iPhone 6s or iPhone 6s Plus and they’ll work on any version of iOS 9 or iOS 10.

Apple’s got more iOS updates on the way and iOS updates can be the root cause of some battery life issues. That’s why we recommend absorbing these fixes so that you’re prepared for all of Apple’s future iPhone 6s iOS updates.

(Note: iOS 9 and iOS 10 come with a Settings Search at the top of the Settings screen. If you can’t find something, you can search for it there.)

Wait Two Days

If you just installed a new update, give it a couple of days before drastically altering your settings or habits. Battery life sometimes takes a day or two to settle in immediately after a new update is installed. Keep that in mind for future iPhone 6s updates.

Use Low Power Mode

If you haven’t started using it already, you’ll want to start using the Low Power Mode that Apple debuted with its iOS 9 update.

Low Power Mode will allow you to stretch out your last 10-20% of iPhone 6s battery life without killing your core services. Best of all, it accomplishes this with one press of a button. Toggle it on, and you’ll save yourself in critical situations.

iOS-9-3 5.51.43 PM

If you’re at the 10-20% mark, you should get a prompt that asks you if you want to turn it on. You can also turn it on in your iPhone 6s’ settings if you need it before that. Go to Settings > Battery > Toggle Low Power Mode on.

Use Airplane Mode in Bad Service Areas

If you’re in a bad service area, your iPhone 6s/iPhone 6s Plus is going to work extra hard to find a signal. This can kill your battery.

To offset this, you can do a few things. You can flip off cellular data or you can kill all of your connections using Airplane Mode.

iOS-9-2 5.51.43 PM

To toggle Cellular Data off, you’ll want to go to Settings > Cellular > and toggle it off at the top there. If that doesn’t work, try using Airplane Mode. You can toggle it off at the top of the Settings screen.

Monitor Your Apps

It’s easy to blame Apple and iOS for your battery life troubles but sometimes it’s a rogue app (or apps) causing the drain.

If you’re noticing abnormal drain, you’re going to want to look into your app usage. If you use an app a lot, it’ll obviously drain a lot of battery. If you’re confident it’s not the constant use that’s killing the iPhone’s battery, you’ll want to dig in.

We recommend getting familiar with the iPhone 6s’ battery usage tool. It’s located in Settings > Battery. It’ll show up under the Battery Usage header.

iOS-9-1 5.51.43 PM

This tool shows you which apps are eating the most battery. You can check the last 24 hours and you can check to see what they’re doing over an extended period of time. You can also, thanks to iOS 9, now check to see when they are eating battery.

If something doesn’t seem right, you’ll want to take a few more steps. First, you can try downloading the latest bug fix update if you haven’t already. If that doesn’t work, try reinstalling the app or apps causing problems.

If that doesn’t help, you’ll want to get in contact with the developer. Or, worst case scenario, uninstall it and find an alternative.

Delete Facebook

A recent piece from The Guardian asserts that the Facebook app is the cause of many iPhone battery life issues. Uninstalling it apparently delivered huge gains to performance so deleting is worth a try if you’re not attached to it.

Limit Background App Refresh

If you have background refresh turned on, apps will download information in the background so that new info is shown when you fire them back up. It’s useful but downloads can eat up battery in the background. This is why we recommend limiting it to the apps you use the most or killing it completely.

To get a grip on this feature, head into Settings > General > Background App Refresh > Turn it off for the apps you don’t use or the apps causing problems. It’s also possible to turn it off completely but you may not want to do that.

Shut Off Location Services

Location Services (GPS) can absolutely wreck havoc on battery life. If you’ve ever used Google Maps or Waze for an extended period of time then you already should know that.

To get a handle on what should use Location Services and when, 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 should be using what when.

iPhone-6s-performance

You might not want some apps using Location Services in the background and you can limit that with a simple tap.

Turn Off Push

Like Location Services and Background Refresh, the iPhone 6s’ push feature for notifications, email, calendar, and more can suck up battery life. You’ll want to manage it.

To look at your Push Notification settings, go into Settings > Notifications. There, you can shut off notifications for all of your apps or apps that you don’t use on your iPhone.

You might also want to think about settings Mail, Contacts and Calendar to Fetch instead of Push. To do that, go into Settings > Mail, Contacts, Calendars and turn off Push.

Manage the Retina Display

Your iPhone’s screen can eat up battery if it’s not managed correctly. The iPhone 6s and iPhone 6s Plus come with sensors that power the auto-brightness feature.

The auto brightness feature can be useful but it sometimes fails to work properly. If you think you can easily manage the brightness of your iPhone 6s Retina Display yourself, try adjusting it manually. It could help save you some battery.

iOS makes this extremely easy. All you have to do is pull up from the bottom of the screen to enter Control Center. From there, just use the screen toggle to adjust your screen brightness. Turn it down when you don’t need the screen to be bright.

Restart the iPhone 6s

If you haven’t turned your iPhone 6s off for awhile, try restarting it. This simple fix has worked for us in the past.

Reset Network Settings

If that doesn’t work, try resetting your device’s Network Settings. This will cause the iPhone 6s or iPhone 6s Plus to forget Wi-Fi passwords to make sure you have those handy.

To do that, head into Settings > General > Reset Network Settings.

Reset All Settings

If you’ve tired all of these little fixes and nothing’s worked, it’s time to take some drastic measures to fix your bad iPhone 6s battery life.

The first step to take is to Reset All Settings on the iPhone 6s or iPhone 6s Plus. To get this done, go to Settings > General > Reset > Reset All Settings and then enter your passcode when the prompt tell you to.

This could take a few minutes and it will force your device to forget your connections (and passwords) but it might fix your battery issues. It will not delete any files.

Downgrade

If that doesn’t work, you could try downgrading to the previous versions of iOS if the downgrade is available and it was working fine on your iPhone 6s or iPhone 6s Plus.

iPhone-6s-review - 13

The downgrade process can be a bit tricky the first time but after you do it once you should be set. If you’re interested in dropping down to an older version of iOS you can read about the process here.

Restore from Backup

If none of these aforementioned fixes work, you can try restoring from a backup or wiping your iPhone 6s/iPhone 6s Plus completely starting from scratch.

  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 9/iOS 10 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.

You should only do this if nothing else works.

Take Your iPhone 6s In

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. (Or another store but we recommend Apple itself.)

Geniuses will be able to run some diagnostics on your phone and they could help you figure out the problem. We once took in an iPhone 5s and discovered a bloated battery was responsible for the battery drain.

If you’re under warranty, and you will be for a year from your purchase date, you might be able to get another iPhone 6s or iPhone 6s Plus for free.

You can find a list of your local Apple Stores right here.

4 Reasons Not to Install iOS 10.3 & 6 Reasons You Should

Install iOS 10.3 If You Want Better Security

Install iOS 10.3 If You Want Better Security

If you value your security, you'll want to seriously consider downloading the iOS 10.3 update on your iPhone or iPad. 

The iOS 10.3 update brings over 60 known patches for potential exploits. That's substantial, even for a milestone upgrade. The previous version of iOS 10, iOS 10.2.1, brought 14 known patches.

Among them is a patch for a Safari ransomware bug that scammers used to extort iOS users who viewed pornography on their device. 

These patches enhance the security on your iPhone, iPad and iPod touch making them ideal for those of you who store sensitive files/data on your device. Most people do.

If you skipped the iOS 10.2.1 update and/or the iOS 10.2 update, know that iOS 10.3 brings their security patches with it as well. Again, the iOS 10.2.1 update had 14 important patches on board. You can see them all right here

If you failed to install Apple's iOS 9.3.5 update, iOS 10.3 will also bring the three crucial security patches it delivered last year. These patch up serious security problems that could potentially expose your calls, contacts, texts, and emails.

If security is important to you, iOS 10.3 is probably worth a download right now.
