When Apple made an announcement and launch of iOS 9 beta at WWDC 2015, many iOS developers downloaded the first beta version with their developer accounts. However, after a few hours, social media forums were inundated with complaints galore.
There was a single voice: iOS 9 beta eats hell lot of battery. There were many who downgraded from iOS 9 beta to iOS 8.3. However, in its second beta version, Apple had resolved this issue. But now iOS 8.4.1 users also face battery life issue on their iPhone and iPad. In fact, this battery life issue occurs after every iOS updates.
Thankfully, there are some ways to fix this issue of battery life on iOS 8.4.1.
How to Fix iOS 8.4.1 Battery Life Issue on iPhone and iPad
There are several ways you can follow to fix the battery life issue in iOS 8.4.1; you can go for either or all.
Apps Could be the Culprits
Your obsession with different apps might wreak havoc on battery of your iPhone or iPad. Before you curse Apple iOS, check how many apps you have used in the last 24 hours. You can also check number of apps used frequently in the last seven days.
Step #1. Tap on Settings app → Tap on General.
Step #2. Go to Usage → Now tap on Battery Usage.
Here, you can see all the apps that eat your battery; on the left, there are names of apps and on the right, you will see battery consumption percentage. This will give you a fair idea to monitor the usage of app or you may uninstall that particular app, which eats up your phone battery.
Background App Refresh
Once you know which apps burn your battery, you can control those apps from Background App Refresh. Go to Settings → General → Background App Refresh. The apps listed here automatically refresh content when your phone is on Wi-fi or using cellular data in the background. Turn off the apps that consume more battery and you can preserve battery life of your iPhone.
If you are a music lover and listening to songs on Apple Music while using your mobile data, you are burning your phone's battery in excess. You should better download the songs locally and enjoy listening to music while commuting or doing your work. This will surely save your mobile data and mobile battery too.
Use Airplane Mode
If you happen to visit a location, where your phone receives weak mobile signals, switch to Airplane Mode on your iOS device. In weak mobile signal zone, your mobile will consume more battery to get connectivity from a distant tower. And this will drain your phone's battery. Turn your mobile on Airplane Mode from Control Center; swipe up from the bottom of your iPhone and tap on Airplane Mode. If you and your phone are in a Weak Signal Zone, your phone will make extra efforts to check more than one mobile towers, and this will burn more battery.
Brightness & Display
Your intention to save mobile battery life doesn’t work in your favor. Let me explain this statement in detail. As a normal user, you would obviously choose Auto-Brightness option from Display & Brightness in Settings. And you are happy that your mobile battery will be saved. It’s a myth. Your mobile uses a range of sensors; these sensors adjust your screen according to different brightness and light conditions. But this doesn’t work well always. Sometimes, this feature increases brightness of your mobile screen without your notice. And this drains lot of mobile battery. You can stop this by toggling Auto-Brightness OFF and start managing the brightness manually from the Control Center of your iPhone.
Downgrade your iOS
As I mentioned above in second paragraph, many iPhone and iPad users downgraded from iOS 9 beta to iOS 8.3 when they faced severe battery drain issue; you can follow the suit. Downgrade your iOS from 8.4.1 to 8.4.
Toggle iCloud Keychain OFF
Many users have come up with another solution of turning off iCloud Keychain; this has enhanced battery performance on your iPhone or iPad.
Step #1. Tap on Settings app → Open iCloud.
Step #2. Scroll down and tap on Keychain.
Step #3. Toggle iCloud Keychain OFF.
This is a trial-and-error trick; if you think that this action hasn't made any difference in battery life, go back and toggle iCloud Keychain ON.
Reboot and Reset
If everything above doesn't yield any result, restart your iPhone or as a last resort Reset your iPhone. This might improve battery performance of your iPhone or iPad.
