iPhone XS Battery Draining So Fast! How To Fix?

Hi, I have iPhone XS. I recently updated it to latest iOS version which is 11.4. And ever since I updated it I am facing this battery drainage problem even on standby mode despite having battery health over 90%. Before that my phone battery was working just fine. Can anyone be of any help?

Method one: Optimize your settings

  1. Adjust your screen brightness
  • To dim, open Control Center and drag the Brightness slider to the bottom.
  • Auto-Brightness adjusts your screen to lighting conditions automatically. To activate it, go to Settings > General > Accessibility > Display Accommodations and set Auto-Brightness to On.
  1. Use Wi-Fi

It’s related to the mobile data section of the device. When you use your device to access data, a Wi-Fi connection uses less power than a cellular network — so keep Wi-Fi on at all times. To turn on Wi-Fi, go to Settings > Wi-Fi to access a Wi-Fi network.

Method two: Update your device to the latest 12.1.3

Apple software updates often include advanced energy-saving technologies, so always make sure your device is using the latest version of iOS. If an update is available, you can plug your device into a power source and update wirelessly or plug it into your computer and update with the latest version of iTunes.

Method three: Keep certain cases away from your device while charging

Charging your device when it’s inside certain styles of cases may generate excess heat, which can affect battery capacity. If you notice that your device gets hot when you charge it, take it out of its case first.

Method five: Enable low power mode

Low power mode reduces display brightness, optimizes device performance, and minimizes system animations. Thus low power mode is an easy way to extend the battery life of your iPhone when it starts to get low.

Method six: Turn off the feature that allows apps to refresh in the background

Go to Settings > General > Background App Refresh and select Wi-Fi, Wi-Fi & Cellular Data, or Off to turn off Background App Refresh entirely.

Method seven: Turn on Airplane mode when you are in a poor cell coverage area

Open Control Center and tap the Airplane mode icon. Note that you cannot make or receive calls while in Airplane mode.

  1. Replace your battery

All rechargeable batteries are consumables and have a limited lifespan—eventually their capacity and performance decline so that they need to be replaced. As batteries age, it can contribute to changes in iPhone performance. So you can check your battery performance to see if your battery should be replaced.

Note: Don’t forget to back up your important data in case of data loss.
