After the September, 18th iOS 7 release, complaints of severe iOS 7 battery drainage exploded onto every Apple-related forum. Do you have the same problem with iOS 7? How to fix iOS 7 battery drain? Read on to find some useful tips.
Updated: Since the release of iOS 8, iPhone users report the same problems with iOS 8. You could also try the following tricks as well as other tips to fix iOS 8 battery life issue.
Just take a look at the Apple forum, you'll find tons of complaints about the iOS 7 battery drain problem, which is mainly for iPhone 5.
However, there are some tips you can use to preserve iPhone battery life, such as factory reset iPhone, trun down screen brightness, disable push mail, etc.
1. Restore iPhone as a new device: A good way to solve the iOS 7 battery drain issue is to factory reset iPhone and restore iPhone to a "new device". Though you'll have to reinstall all apps, the factory reset helps to solve all manner of performance and battery life issues. To do this, go to Settings > General and find "Reset" option at the bottom of the menu.
2. Restart iPhone: Like computers, iPhone might also need a reboot occasionally. This is because rogue apps doing things they shouldn't is a key reason for battery life issues in any phone, and a proper reset will fix this in many cases.
A long press on the power button (around three seconds) and iPhone will show the power off slider that turns the phone off properly. For a "hard" software reset, press down on both the Home and power buttons until the screen goes black.
3. Turn off cellular data: The apps running background will consume battery. Turning off the cellular data means you won't be able to browse the internet without Wi-Fi, and apps won't access the internet in the background. Go to Settings > Cellular and select the "Cellular Data" option. This will turn off any feature that uses the internet, including Siri.
4. Turn down screen brightness: Most iPhones use automatic brightness, taking readings from an ambient light sensor on the phone's front and then decides how bright the IPS screen's backlight need to be. However, you can save battery power by changing the base level of brightness.
In the Wallpapers & Brightness menu of Settings, or in the Control Center menu, you'll find the slider (and the auto brightness toggle). accessed by swiping up from the bottom of the screen.
5. Disable AirDrop: Using AirDrop, the brand new feature of iOS 7, users can share files with other supported Mac computers running OS X 10.7 or later and iOS devices running iOS 7 or later through Wi-Fi. But it drains battery by searching for nearby iPhones. If you want to save iPhone battery and disable AirDrop, find an AirDrop toggle in the Control Center pop-up menu, accessed by swiping up from the bottom of the screen.
6. Disable Push Mail: Instead of having your iPhone or iPad or iPod check for mails constantly, you can disable Push email, which will reduce strain on the battery. This can be done by:
7. Turn off apps on Notifications: Another change in iOS 7 is the pull-down notifications menu. You can find new emails, texts and so on, and this will drain a little bit of battery. To turn off apps in the Notifications bar, you can go to Settings > Notification Center. Here you'll find toggles for calendar info, reminders as well.
Apple is likely to improve iOS 7battery efficiency in future updates. However, iOS 7 does appear to eat more power than iOS 6. If the tips above still don't seem enough, check the post How to Downgrade iOS 7 to iOS 6 to see if this will help.
