Apple’s brand new iOS 8.1.2 update brings bug fixes to iPhone, iPad and iPod touch owners. However, as we mentioned, it not only fails to fix some persistent iOS 8 issues, but also brings some issues of its own. Especially some iPhone and iPad users are noticing bad iOS 8.1.2 battery life and today we will tell you how to fix it.
Last week, a few weeks after an iOS 8.1. The company’s latest update is iOS 8.1.2, a minor bug fix update that gives control of just over 20MB for most iPhone and iPad users. It is directly addressed to a ringtone issue that burgeoned after the iOS 8.1.1 update.
While the iOS 8.1.2 update aims to fix iOS 8 issues, the update seems to cause some issues for iPhone and iPad owners. In particular, broken Wi-Fi and Bluetooth, poor performance and usual complaints about bad battery life. While battery life issues always seem to plague iPhone and iPad users after an update, most of the time it is not the actual update that is causing the problems. Apps and other services are often the culprit.

How to Fix Bad iOS 8.1.2 Battery Life on iPhone or iPad
With that in mind, we want to try and fix bad iOS 8.1.2 battery life for you. This guide provides help to get better battery life on iPhone, iPad and iPod touch. This guide will help with iOS 8 battery life, but assumes you’ve already upgraded to iOS 8.1.2 for the fixes it brings to iPhone and iPad.
Find Apps That Eat Your Battery
If you want to fix bad iOS 8.1.2 battery life, you will need to be proactive and one of the first steps you should take is to address your apps. Third-party apps have a tendency to wreak havoc on battery life. If you use an app a lot, it will drain your battery. However, there are times when bugs or problems can cause an app to cheat and kill your fee.
What you’ll want to do is start using the battery life utility that Apple included in the iOS 8 update. To get started with this tool, go to see which apps are using the most battery life in the last 24 hours and the last seven days. When you find an app that’s using a lot of battery life, you can limit your use while it’s out of power, stop background activity, or remove it entirely from your iPhone or iPad.
You’ll also see where poor cellular coverage is to blame for bad iOS 8 battery life. When your phone needs to seek a signal, its battery drains faster, so keep that in mind when you’re in spotty areas. You may need to turn on Airplane mode when you don’t have real cell signal.
Limit Background App Refresh
Speaking of apps, your iPhone or iPad can refresh apps in the background so the data is available when you open the app. While this is a great tool for those of you who use phones or tablets all the time, it’s also a great way to drain your battery life.
Instead of turning off Background app refresh entirely, you should find apps that are using it a lot and turn them off one by one to see if it fixes iOS 8.1.2 battery life issues. That way, you can keep apps that don’t use a lot of juice. If you don’t want to take the time to do this, you can remove the feature entirely.
To start it, go to. While there are other steps you need to take, this will help you conserve your precious iOS 8.1.2 battery life.
Stop Using Auto-Brightness
Apple’s iPhone and iPad contain sensors that change the screen brightness based on the light in your current environment. Often times, sensors increase your screen brightness to unnecessary levels, killing your precious battery. You probably don’t want this to happen, so it’s in your best interest to remove this feature from your daily use.
To turn this feature off, go here and you’ll be able to manually adjust the brightness of your screen to help keep battery drain at a minimum. Note that you can always increase or decrease the brightness on your own using the Control Center whenever you need it. Control Center is the feature that opens when you swipe up from the bottom of the screen.
Restart or Reset Your iPhone or iPad
If you find that iPhone battery life is very short or iPhone is getting hot after installing iOS 8.1.2, you need to restart or reset it. Press and hold the power button and slide to turn it off for a normal reboot. Believe it or not, this has fixed battery life issues in the past. It’s a simple fix but worth a try if things start to go bad after upgrading to iOS 8.1.2.
You can also try to reset the iPhone or iPad by pressing and holding the home button and power button for about 10 seconds. This will not remove any of your data and sometimes this is enough to fix everything that is draining the device’s battery life. It’s worked for us in the past and it might work for you too.
reset all settings
Here you’ll start seeing iOS 8.1.2 battery life fixes that can fix major issues killing your iPhone or iPad’s battery life. If you look at the iOS 8.1.2 battery usage in Settings and see that the usage and standby numbers are the same, this is the step you need to take.
Go to and enter your password when prompted. This process will take up to five minutes to complete and will reset all your settings to default. This will not remove any data or photos from your iPhone and iPad. Again, this is the first step you should take if you notice massive battery drain on your device and it has been fixed for many users in the past.
Restore iOS 8.1.2 Update
If none of this works, you should try reinstalling the iOS 8.1.2 update using restore. You need to do this with iTunes installed on your computer. This will completely wipe your phone. You can try restoring from your backup after the update, but if the problem comes back you’ll want to do it again without restoring from backup. Here’s how to do this.
- Plug and .
- Turn off Find My iPhone – option.
- on iTunes.
- Follow the prompts and iPhone .
- When the process of putting your information back on iPhone is complete, or Select.
This is not a short process. Expect to spend 20 to 45 minutes for this process and longer if you restore from backup. It varies from device to device and person to person.
Genius Bar/Replacement
If we somehow fail, you should make an appointment with Apple and get an Apple Genius to take care of your phone or tablet. Before you go, back up your iPhone or iPad and ask them if your battery life is bad. They can test this at the store and if you have warranty they will replace it. One year warranty by default, two years with AppleCare+.
In the past, Apple Geniuses discovered swollen batteries and all sorts of other issues, so if none of these software tweaks work, there may be a hardware issue at play. It’s worth a try if nothing here solves your problem.
