iPhone Battery draining fast all of a sudden is a common iOS problem and iPhone and iPad users are often expressing their frustration to Apple and its customer service representatives for abnormal drain of their device batteries. Many users have complained that their iPhone 6 battery draining fast all of a sudden after hey upgraded their devices to iOS 10 or 11 and they can’t even make it through the day without charging. If you’re having the issue of’ ‘iPhone battery draining fast all of a sudden’ and you wonder why is my iPhone 6 battery draining so fast then follow these 10 proven tips to make your battery last longer without sacrificing its functionality. If you follow these tips correctly the battery life of your iPhone is definitely going to improve significantly be it your iPhone X, iPhone 8, iPhone 7, or iPhone 6 battery.

Before I go to the specific tips to solve your problem- ‘why is my iPhone battery draining so fast all of a sudden’, follow these general performance tips applicable for all iOS devices as recommended by Apple:

  1. Avoid extreme ambient temperatures. iPhone, iPad, iPod and Apple Watch work best at 0° to 35° C (32° to 95° F) ambient temperatures. Recommended storage temperature is –20° to 45° C (–4° to 113° F). Avoid exposing your device to ambient temperatures higher than 35° C (95° F), which can permanently damage battery capacity;
  2. Remove your device from its case during charging. If you charge your device when it’s inside its case it may generate excess heat, which can affect battery capacity;
  3. If your device is in storage for a long time, the environmental temperature and the percentage of charge on the battery when it’s powered down for storage, may affect the overall health of your battery.

It is, therefore, recommended,

  • Not to charge or discharge your device’s battery fully when it is stored for an extended period of time. In such cases charge the battery to around 50 per cent only. If you store the device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge. Conversely, if you store it fully charged for an indefinite period of time, the battery may lose some capacity, leading to shorter battery life;
  • Power down the device to avoid additional battery use;
  • Place your device in a cool, moisture-free environment that’s less than 32° C (90° F);
  • If you plan to store your device for longer than six months, charge it to 50 per cent every six months;

Now follow these 10 proven tips to fix the issue – ‘iPhone battery draining fast all of a sudden’:

1.  Fix ‘iPhone Battery draining fast all of a sudden’ – Check Battery Usage

When it comes to making your battery last longer on iPhone or iPad, the first thing you need to do is to check which Apps drains your device-battery most. If you are using iOS 9 and later version it has an excellent new feature, called Battery Usage. This feature allows you to know which apps eat your iPhone battery the most.

You can update the guilty apps as a first step, and if the app still causes problem, you can eventually remove it. You can always re-download these apps at a later date if you find that these apps are not responsible for your iPhone battery drain issue.

Here are the steps to follow to check Battery Usage on your iPhone or iPad:

i. Go to Settings > tap on Battery;

ii. On the Battery screen, wait for a few second for Battery Usage feature to load;

Enabling Low Power Mode would make your iPhone battery last for several hours longer than in normal mode. When Low Power Mode is on, mail fetch, background app refresh, automatic downloads and some visual effects are reduced or turned off automatically. This will greatly increase battery life on your iPhone. When it is enabled the colour of the battery icon will turn yellow. To enable this, go to settings > tap Battery > toggle the switch next to ‘Low Power Mode’ to turn it on.

This feature is only available on iPhones that are running with iOS 9 and later, and iPad doesn’t have this feature.

3. Fix ‘iPhone Battery draining fast all of a sudden’ – Turn off ‘Raise to Wake’

‘Raise to Wake’ option in your iPhone settings is turned on by default with iOS10. Raise to Wake feature automatically wakes your iPhone or iPad screen as soon as you pick it up from flat on a surface.  If you move around a lot with your iPhone in your hand, your iPhone screen wakes up automatically and remains constantly turned on which, drains your battery unwittingly. Therefore, turn off ‘Raise to Wake’ feature on your iPhone to save battery life.

To do this, go to Settings > tap Display & Brightness > toggle the switch next to ‘Raise to Wake’ to turn it off.

4. Fix ‘iPhone Battery draining fast all of a sudden’ – Update apps (including iOS update)

Sometimes the outdated apps can also create battery draining issue. Normally software updates often include bug fixes some of which at times may be the cause of your iPhone battery draining fast. When Apple releases a new iOS update, developers also prepare and optimize their apps for the latest version. Therefore, ensure that your iPhone or iPad is working with the apps with latest iOS version. Taking time to update all the available apps may affect your iPhone or iPad battery life considerably.

To update apps, open App Store > Tap ‘Updates’ at the bottom right of the screen > Tap ‘Update All’ in the upper right corner.

‘Background App Refresh’ refreshes the apps on your iPhone in the background which is to say your apps continue to update even when you’re not using them. This is intended to save loading time of the apps. But allowing all your open apps to continually update and refresh in the background makes your iPad or iPhone battery drain fast. Therefore, you should turn this feature off to extend battery life on your iPhone or iPad.

To turn it off go to Settings> General> Background App Refresh> Toggle ‘Background App Refresh’ to off position.

6. Fix ‘iPhone Battery draining fast all of a sudden’ – Disable ‘Location Services’

iPhone Location Service also drains your battery unsuspectingly. iPhone’s location service determines your approximate location using GPS, Bluetooth, Wi-Fi hotspot and mobile tower location and pass on the information to different  apps that help to find restaurants, and more for you. But, like any service that sends data over a network, it needs battery power to work. Therefore, if you don’t need to use Location Service and don’t plan to use it right away, turn it off and save some battery power.

To turn it off go to Settings > tap Privacy > tap Location Services > toggle the switch next to ‘Location Services’ to off position.

7. Fix ‘iPhone Battery draining fast all of a sudden’ – Turn on ‘Airplane Mode’

One of the major reasons of your iPhone battery draining fast is poor cellular service. When you are in a place of low signal, your iPhone will increase the power to the antenna in order to stay connected enough to receive calls and maintain a data connection. This depletes your iPhone battery in no time.

To prevent iPhone battery draining fast, turn on ‘Airplane mode’ by swiping up from the bottom of Home screen of your device to access Control Centre and tapping on the Airplane mode icon or go to Settings > Airplane Mode > Toggle ‘Airplane Mode’ to on position. Once you’re back in an area with a strong signal, use the same steps to turn off Airplane mode.

But please bear in mind that during the time when your iPhone’s Airplane mode is turned on, you cannot make or receive any phone calls.

8. Fix ‘iPhone Battery draining fast all of a sudden’– Turn off ‘vibration’

To turn off vibration go to Settings > Sounds > turn off ‘Vibrate on Rings’ and ‘Vibrate on Silent’.

Auto-Brightness feature of iPhone adjusts display brightness of the device according to the lighting of your existing surroundings. This feature always keeps the display brightness at its highest level depleting your battery life. In order to improve your iPhone or iPad battery life, you should, therefore, turn Off Auto-Brightness feature and adjust the brightness yourself to a lower level according to your requirement.

To turn it off go to Settings > tap on Display & Brightness > Turn off Auto-Brightness and adjust the brightness to a lower level by swiping to left.

10. Fix ‘iPhone Battery draining fast all of a sudden’ – Turn off ‘Wi-Fi’ when not in use

If you do not turn off Wi-Fi when you are not connected to a Wi-Fi network it makes the Wi-Fi of your iPhone or iPad to hunt around for Wi-Fi networks it could join. This will obviously consume battery power. Therefore, when you are not using Wi-Fi you should turn it off to save batter life on your iDevice.

To do this go to Settings > tap Wi-Fi > toggle Wi-Fi to off position.
