It has been 1 year since Apple launched the standard iPhone 6s, and 6s Plus. Apple rated for 10 to 12 hours of battery life while browsing the web, checking email, listening music and chatting. However, sometimes things go wrong, your battery life drain fast and cannot last the time using as your expectation. In this article, we will tell you what you can do to fix battery life on your iPhone and get on with your life.

  1. Test on standby

You feel like the battery only lasts half as long, the first step to fix it is figuring out if you are using it twice as much.

Therefore, you should note down how much battery life you have left. Then take a rest for your iPhone for 20-40 minutes. When you turn it back on, note down how much battery left again. If there is not a big change while it is in standby mode, you do not worry as your battery life will return to normal when your usage is normal.

If your iPhone continued to drain fast, even when you were not  using  it, you should try other ways below

  1. Reset your iPhone 6S, 6S+, or

Rebooting or resetting is the oldest trick to troubleshoot the battery issue. Sometimes a good reset is a great way to get rid of this issue.

  • Press and hold down both the Power button and the Home button at the same time for about 10 seconds
  • Keep them held down until you see an Apple logo.
  • That is done!

Once your iPhone has rebooted, repeat the previous steps and see if battery has returned to normal. If not, try the following solution.

  1. Check usage of your battery

iOS 9 lets you know exactly which apps and services are using your battery.

  • Open Settingsfrom your Home screen.
  • Tap on Battery


  • Wait a moment for Battery Usageto calculate
  • Tap on the Show Detailed Usagebutton to get a background power usage.
  • Tap on Last 7 Daysto get a larger look at power consumption over time.


After that, you can force quit a range of apps to help your power consumption back to normal.

  • Double click the Home button to open the fast app switcher.


  • Swipe to the app you want to force quit.
  • Touch the app card and slide it up and then turn off the screen

If an app seems to misbehave, you should delete then re-install it or even switch to an alternative app for some of your activity.

  1. Low Power Mode

If your battery life is normal but you want to get even more out of it, you can always use a power bank. If you do not have one handy, you can turn on the Low Power Mode.

  • Open the Settings from your Home screen.
  • Tap on Battery.
  • Toggle Low Power Modeto on.


You can see when Low Power Mode is enabled by looking at the color of the battery icon. If it turns yellow, that means the mode has been enabled. It will automatically turn off when you recharge above 80% or more, so if you want to keep it on, you will have to switch it on every time.

You can also turn on Low Power Mode quickly via Siri. Just say “Hey Siri, turn on low power mode!”. That is done!

  1. Restore your iPhone as new

Sometimes restoring from another backup, especially a backup of a different device, can be a good solution. However, there are things you do not want to use.

Therefore, you can set up your iPhone as new. It can lose all your app data, but if you are facing continual issues, and nothing else can fix it, setting up as new can be the best solution.

You will have to set up almost everything again, including passwords and settings, and you will lose all your saved data like game levels, music, videos and activities, but in most cases it can improve your battery better.
