The iOS 8 update delivers new features to the iPhone and iPad, and for many users one of these new features is bad iOS 8 battery life. We’ll show you how to get better iOS 8 battery life on the iPhone or iPad.
iOS 8 battery life is pretty good in our early reviews, but some users are mad that their iPhone doesn’t last as long on iOS 8. This is one of several iOS 8 problems that users ran into after the iOS 8 update arrived this week. The complaints vary from bad iOS 8 battery life to horrible fast draining on the iPhone.
iOS 8 battery life problems can impact any device running the free update, but iPhone 5s, iPhone 5, iPhone 5c and iPhone 4s owners will notice any changes to battery life more than others while trying the new iOS 8 features and using the iPhone all day.
Here are settings you can change and things you can do to get better iOS 8 battery life on your iPhone and iPad.
9 iOS 8 Battery Life Tips
You’ll notice if your iPhone battery life drops after installing the iOS 8 update, but in any case you can expect 8-12 hours of usage on the iPhone 5s, iPhone 5c, iPhone 5 and iPhone 4s. This all varies based on your device and how you use it, but if the usage shown is less than 8 hours and your battery is dead, there is clearly something going on.
Find Apps Using Your Battery Life
The iOS 8 update adds a new feature that shows you what apps are using most of your battery life. Very often bad iPhone battery life is linked to a broken or misbehaving app. This new iOS 8 feature lets you see what apps use most of your battery life and even find usage and background activity. A chat app like Google Hangouts can use a lot of battery life, even if you aren’t in it all day.
To see what apps are using your iOS 8 battery life, go to Settings -> General -> Usage -> Battery Usage. On this screen you can see what apps use your battery the most in the last 24 hours and in the last 7 days.
You may need to uninstall an app to get better iOS 8 battery life, but the solution may be to avoid using battery hogging apps during the day — like games and watching media.
Turn Off Background App Refresh
One of the first things you can try to get better iOS 8 battery life is turning off Background App Refresh. This feature lets apps connect and update in the background, so they can show updates as soon as you open them, but this also uses more battery life. Apple shares on the iOS 8 Background App refresh screen, “Turning off apps may help preserve battery life.”
Go to Settings -> General -> Background App Refresh -> Turn it all off or off for individual apps.
You can turn Background App Refresh off for all apps or only for certain apps. If you see an app listed with background activity at the top, you may want to simply turn off that app.
Turn Off Push Email
If you use push email to get messages from work as soon as they arrive, you are slowly draining your battery life with every pushed message. If you don’t need email delivered instantly you can turn off push email and get better battery life.
Go to Settings -> Mail , Contacts, Calendars -> Fetch New Data – > Choose the setting for each email account.
The best option we’ve found is to push the time between checking for new messages to Fetch every 15-30 minutes instead of constantly looking.
Turn Screen Brightness Down
The iOS 8 update didn’t crank up your screen brightness, but this is one of the easiest ways to get better iOS 8 battery life.
Swipe up from the bottom of your home screen to open Control Center. Slide the brightness indicator to the left to turn the brightness down.
You can go to Settings -> Display & Brightness -> Auto-Brightness -> Off. Normally you can leave this on, but if you need to make sure the battery lasts all day while on a trip turning it off and leaving brightness at a minimum will help you get better battery life.
Turn Off 4G LTE
Using the faster 4G LTE network can use more data, and if you are on the edge of coverage this may be the quickest fix for bad iOS 8 battery life. Try turning this off to see if it improves. If it does you may need to leave this off when you are in this area.
Go to Settings -> Cellular -> Enable LTE -> Off. This is not a setting I would leave off all the time, because it makes anything related to the Internet take longer, but in some cases it is a quick fix.
This is a dramatic step to get better iOS 8 battery life, but if you only need to play games or read a book, and you don’t want the iPhone to die, you can turn on Airplane mode.
Pull the Control Center up from the bottom of your home screen and tap on the small plane icon.
This turns off WiFi and Cellular radios completely, so you can’t do as much with the iPhone or iPad, but the battery lasts longer for offline activities like taking photos and playing games.
Restart the iPhone
If you have not restarted the iPhone since you installed the iOS 8 update or for a few days even, go ahead and turn the iPhone off then back on.
Sometimes a simple restart is enough to stop whatever was causing bad iOS 8 battery life and reset things so the battery will last all day.
Hold the power button down until the screen changes, then slide to the right to power off. After a minute or two hold the power button to turn it back on.
Reset All Settings
When you check the iOS 8 battery usage in our first tip you may see usage and standby listed as the same. If this is the case you need to take more drastic measures because something is wrong with your iPhone. The first thing to try is Reset All Settings. This does not delete your data or wipe the phone, only the settings. If something is messed up this may fix horrible iOS 8 battery life in about 5 minutes.
Go to Settings -> General -> Reset -> Reset All Settings. If prompted, enter your PIN or pass code. Wait for the device to restart and then use your device like normal. You may need to reconnect to WiFi, Bluetooth and change some other settings, but your apps, photos and accounts are still all there.
Restore the iOS 8 Update
If none of these iOS 8 battery life tips fix problems after your iOS 8 update you may need to backup the iPhone and restore from scratch. Perhaps something went wrong during your iOS 8 update, or there is just a bug from the upgrade, but this process will wipe it clean and install iOS 8 from scratch. This can solve a lot of problems.
You’ll need to back up the iPhone or iPad because this will delete all of your photos, apps and data from the device. You can restore from a backup, but there is a chance that will bring some problems back so the best bet is to set this up like a new iPhone.
- 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 8 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.
This process takes 15 to 30 minutes depending on download times and if you need to backup or restore.
iPhone Battery Replacement
If you experience bad iPhone 5 battery life after the iOS 8 update you should contact Apple to see if your iPhone is part of the replacement program. If your iPhone 5 battery life is bad it may qualify for a free battery replacement. Check your serial number on Apple to see if you qualify.
Another option is to use your warranty or AppleCare for a replacement battery if Apple’s test confirm there is something wrong with the battery. If you are under warranty or AppleCare+ there is no fee for a battery replacement, as long as Apple diagnostics show that the battery is bad. The best way to do this is going to an Apple Store, or start a service request online.
If you are out of warranty you can get a battery replacement from Apple for $79 plus a $6.95 shipping fee.
If you use any of these services you need to backup your iPhone before you go to an Apple Store and may need to wipe the phone as well.
