iPhone 6 battery suddenly draining fast!

Last night I watched my battery go from 75% to 10% to dead in a matter of minutes. Charged it overnight and watched it do the same thing again today. I’ve gone through the normal steps of closing all apps, turning off notifications, turning off location services, switching to low power mode, doing a hard reset, cleaning the charging port, and updating to the latest ios version. Nothing helps! This phone is 2 years old and has worked like a charm until last night. I use this phone daily for work and don’t understand why this would suddenly happen. Please help!

When you become sure about the battery-consuming apps, you should delete those apps to avoid battery-dying issues on iPhone/iPad.

Tip 2: Switch your phone to ‘Airplane Mode’

Poor cellular service is yet another reason for your iPhone battery draining fast suddenly. If you are in an area where there is a very low signal or coverage area then your device increases the power in order to receive calls or maintain a data connection.

Switch phone to airplane mode

This reduces the battery power a lot. So the best way to avoid the issue is by turning your phone to Airplane mode. Simply go to Settings > Airplane Mode > Toggle Airplane Mode to the ON position. When you come back to a strong signal area then do the same process to switch off Airplane mode.

NOTE- You will not be able to make or receive calls while your phone is in Airplane Mode.

So, you should reduce the number of widgets from the Lock screen and stop your phone battery from dying fast. Follow the steps to remove widgets on your phone:

  • This will open a Delete button, click on Delete
  • At last, click on Done

Tip 5: Switch off ‘Wi-Fi’ when in not use

Unnecessary turning on ‘Wi-Fi’ on your device is not a wise choice; instead, you are draining your battery fast without any reason. Turning on Wi-Fi can make your phone search around for any Wi-Fi network to join. This consumes more power and battery, which is not required. So it’s better to turn it off and save the battery on your phone.

For this, you need to go to Settings > click on Wi-Fi > toggle Wi-Fi off

Switch off WiFi when not in use

Tip 6: Update all Apps on your phone

If your installed apps are not up to date then also the battery-consuming issue is one of the common problems. Many times the apps are automatically updated in the background which results in a battery-dropping issue.

Update all apps on your phone

Apart from this, when the app is outdated then it will not work properly and you can notice sudden draining of the battery. So without wasting any time, go to ‘App Store’ and click on ‘Update All’ to update all your apps.

Tip 7: Use location service when required

If your location service is switched on then it is yet another reason for your iPhone 6 battery draining fast. You might have noticed that different apps want to know and use your location. This can be a problem for your phone as Location Service is generally not an important thing to use always.

Use location service when required

So if you think that Location Service is not necessary for you then go to the apps and select whether you can use location service always or Only when you are using the app or Never.

Many apps use the location service only when you use the app and to do that:

  • First, open Settings > click on Privacy > click Location Services
  • Now select the particular apps to choose when you want the location service to be used
  • You can also select the Never option when the app does not need any location information

Tip 8: Switch off Bluetooth service

When your Bluetooth service is turned on then also there is a chance that your phone battery drains fast and you might have noticed it. When it is of no use then disconnect the pairing accessories. Turn off the Bluetooth feature by following the below steps:

  • First, open the control center by swiping up
  • Now click on the Bluetooth icon just next to Wi-Fi and then turn off the feature
  • When you have disconnected all accessories from Bluetooth, check your phone battery

Switch off Bluetooth service

If the battery works properly then you don’t have to change the battery and it is in good condition. Remember to turn off the Bluetooth service when not in use and extend battery life.

Tip 9: Close the apps running in background

Whenever you open any for use then you generally don’t close and this in return, continues to work in the background. Those apps which run still in the background are very much responsible for eating up your phone’s battery.

Close the apps running in background

So if you want a better battery life then close all the apps running in the background before you suffer from severe issues. Simply click on the Home button twice to allow the app to switch on. There you can see how many apps are opened. Just swipe up the apps selectively and they will all close.

Tip 10: Switch off Raise to Wake on iPhone

So you should disable it by going to Settings > click on Display & Brightness > toggle Raise to Wake OFF

Switch off raise to wake on iPhone

Tip 11: Change the battery

This can be the simple way to solve the iPhone 6 battery draining fast all of a sudden problem.

Change the battery

Tip 12: Switch off background app refresh

The Background App Refresh is yet another concern for the fast battery draining problem. It works by allowing all the apps to refresh in the background. When there is an internet connection, then the apps are refreshed and at the same time, the battery also drains.

Switch off background app refresh

  • Now click on the green button just next to Background App Refresh

Tip 14: Enable Reduce motion

Many users want to enable interesting effects on their phones like animations. Though they look good at the same time, it reduces battery and makes your device hang out. Some message apps are flashy which drains lots of battery power.

Enable reduce motion

So it will be better to switch off all animation effects on your phone and a little bit of effect is in every app or device, so that is not a big problem. To enable reduce motion, you should go to Settings > General > choose Accessibility > click on Reduce Motion > Toggle Reduce motion

Tip 15: Allow Low Power Mode

Even enabling low power mode on your iPhone/iPad is yet another way to overcome the low battery life of your phone. When this feature is turned on then all the background app refresh, automatic downloads, mail fetch, etc are reduced or get off automatically.

Allow low power mode

Doing this will surely improve the battery life and remember that the color of the battery icon will become yellow when it is enabled.

Go to Settings > Battery > toggle switch next to ‘Low Power Mode’ to turn on

NOTE– This powerful feature is only available on iPhones running on iOS 9 or later versions and iPad don’t have the feature.

Tip 16: Switch off “Auto-Brightness” feature

The feature of auto-brightness somewhere makes your phone battery low fast because it adjusts according to the requirement. In fact, this feature always keeps the display brightness at its high level and hence reducing the power of the battery.

Switch off auto brightness feature

So it’s better to turn off the Auto-Brightness feature on your iPhone and adjust the brightness according to your need.

Simply go to Settings > click on Display & Brightness > turn off Auto-Brightness and then as per requirement, set the brightness.

Tip 17: Restore iPhone to Factory Settings

Even restoring the iPhone to factory settings via iTunes is also helpful in fixing the battery problem. When you come across sudden battery drops on your phone after updating then restore your phone. But this process can lose your data so backup all your important data before proceeding further.

  • Now click on the device icon and then hit on “Summary
  • After that, tap on ‘Restore iPhone’ and confirm it. Wait for some time and your phone will restart and will come back to normal


  • Your phone is best used in temperatures at 0 degrees to 35 degrees (32° to 95° F) and its storage temperature is –20° to 45° C (–4° to 113° F).
  • When your device is in storage for a long time then the environmental temperature and percentage of battery charge when powered on may affect the overall health of the iPhone battery
