iOS 12 Draining Battery Fast? How To Fix It

Typically, the battery on an iPhone could last up to 8-11 hours with normal use. But if you notice that your iPhone battery is draining faster than normal after a full charge, it could be a problem, which requires solutions. Tackled in this post are a number of useful battery-saving tips that can help you address your iPhone battery draining problem. Read on to know what caused your phone battery to drain faster and what should be done to save up your phone’s battery life.

What causes the battery to drain faster than normal

If your phone battery dies so fast, there are only two possibilities. The first one is something on your phone is draining much power than usual. To fix the problem, you need to take a look at both the hardware and software on your phone. As solving hardware factors usually requires help from an iPhone technician, you can first work on the software aspect. To let you know which factors to rule out, I have listed the most common culprits as follow:

  • Bad updates

You might face the battery draining issue after installing updates on your phone. The fast battery drain is listed as one of the most common problems encountered by many iPhone users. In this case, the problem is due to some software bugs. Apple often addressed this problem by releasing a follow-up update including a fix patch. You can consider this as the main cause if your phone just started to experience a rapid battery drain after new update installation.

  • Rogue apps

Unstable apps might also become rogue apps at any time. When your apps act up, adverse symptoms will transpire including the fast battery drain. Apps that aren’t outdated are usually the ones misbehaving when a new software update is installed. Apps running in the background will eventually cause the processor to work hard, which leads to constant power consumption.

  • Misconfigured settings

The way you configure your iPhone settings location services, and other battery-consuming iOS features are also the attributes that could cause the rapid battery problem on your phone. Because of this, you should optimize and adjust these settings to reduce power consumption.

These are the common factors you should look at and clear out when fixing the battery draining issue on your iPhone.

How to troubleshoot iPhone battery draining issue

If you are facing the difficulty with your iPhone, try these procedures to rule out software-related factors that have triggered your phone battery to drain fast. All of them are generic solutions and the steps are also applicable to any iPhone variants.

Solution 1. Reboot your iPhone

If it’s the first time you see your iPhone battery is draining fast, restarting your device is also a good solution to fix it. Sometimes, the symptom is triggered by random app glitches that are usually rectified by a simple reset or forced restart on your phone.

Soft Reset iPhone

A simple restart on iPhone X or later models is carried out by following these steps below:

  1. Press and hold the Power button along with one of two Volume button until you see the Power off slider on the screen.
  2. Drag the slider to turn off your phone completely.
  3. Wait for about 1 minute, press the Power button again to power your iPhone back on.

On the iPhone 8 Plus, or older models, a soft reset can be done in this way:

  1. Press and hold the Power button until you see the Power off slider on the screen.
  2. Drag the slider to the right to switch it off completely.
  3. After 1 minute, press and hold the Power button again to power it back on.

Wait for your phone to complete rebooting and then check if that fixes the problem.

Force Restart iPhone

If you are using iPhone 8, 8 Plus, or later models, follow these steps to force restart your iPhone:

  1. Press and quickly release the Volume Up button.
  2. Do the same with the Volume Down button.
  3. Finally, press and hold the Power button and release it until the Apple logo shows up.

On iPhone 7 and iPhone 7 Plus models, it can be done this way:

  • Press and hold the Volume Down + Power button simultaneously and release them when the Apple logo shows up.

For earlier iPhone models like the iPhone 6s, 6s Plus, 6, 6 Plus, SE and 5s, a forced restart can be done this way:

  • Press and hold the Power button along with Home button for a few seconds and release them when you see the Apple logo.

Both these restarts are effective in minoring software problems including fast battery drain caused by a rogue app or minor system bug. None of them will affect the data saved on your phone’s internal memory.

Solution 2: Manage your apps

As I said earlier, rogue apps are also among the common culprits. So, you need also to rule them out. One of the easiest ways is to update them. Similar to iOS updates, app updates also include fix patches that are programmed to address certain bugs caused by unstable apps.

Update third-party apps on your iPhone

Third party apps you’ve downloaded from the App Store can be the culprits. If you haven’t set your apps to auto-update option, you can also update them manually. Here is what you should do:

  1. From your Home screen, open App Store
  2. From its main screen, scroll down and then select Updates section. There will be a new screen including a list of apps with pending updates shown up.
  3. To update individual apps, simply tap on Update button next to each app.
  4. If you want to update multiple apps at once, tap on the Update All button on the right side of the screen.

Once you update your apps, reboot your iPhone to refresh the memory as well as apply the recent changes.

Delete bad apps from your iPhone

If updating your apps does not help, you should delete the bad apps on your iPhone instead. But before doing so, you need to check which apps are eating up your iPhone battery. The easiest way is to head to your phone’s battery usage section. To do so:

  1. Head to Settings on your Home screen.
  2. Tap on Battery > Battery Usage
  3. Tap on Last 24 Hours or Last 10 Days tab to see more details about the battery usage at a certain period of time.

If you find any app that’s using much power than it should be, uninstall that app. To uninstall it from your iPhone, just follow these steps below

  1. Find the app that you want to delete from the Home screen
  2. Tap and hold on its icon until it starts jiggling.
  3. Tap on the icon on the left of the app icon to delete it.
  4. Select Delete popup to confirm uninstalling the app from your iPhone.

After you delete the bad apps, press the Home button or return to the Home screen to stop the apps from jiggling. After that, restart your iPhone to remove junk files and corrupted caches.

Before getting started, make sure to keep your iPhone always connected to the charger during the update process. By this way, you will not fear to face a corrupt system from power interruptions.
