The battery is one place where no person wants to compromise. Normally, when a phone starts to lose charge sooner than expected is when we plan to change it. If the battery lasts a decent amount of time, we can still use some great devices.

That’s why today, I’ll be providing you with a few ways you can save your battery life on a used iPhone 11

In this article, I’ll cover the following:

  • Why does the battery of the iPhone 11 degrade over time
  • 10 ways to save your battery on a used iPhone 11

Let’s start by discussing the factors that cause the degrading effect of a battery.

Why Does the Battery of the iPhone 11 Degrade Over Time

The battery in an iPhone 11 (or any other smartphone) will degrade over time because of a variety of factors, including normal wear and tear, number of charge cycles, and age. As a battery is used, its ability to hold a charge diminishes, resulting in shorter battery life and reduced performance. This is because the chemicals inside the battery break down over time, which can affect its ability to store and release energy. 

Additionally, the number of charge cycles a battery goes through can also affect its performance. For example, a battery that is charged and discharged on a daily basis will degrade faster than a battery that is only charged once a week. 

Finally, the age of the battery can also play a role in its performance. As a battery gets older, its ability to hold a charge will naturally decrease, which can lead to reduced battery life and performance. 

Overall, it’s important to understand that battery degradation is a normal part of the life of a smartphone, and it’s to be expected that the battery in an iPhone 11 (or any other smartphone) will degrade over time.

10 Ways to Save Your Battery On a Used iPhone 11

Normally, a used iPhone 11 is a great phone, but it’s not perfect. One of the major complaints about the iPhone 11 is its battery life. That’s why here are some ways you can extend the overall battery life:

1. Turn Off Unused Apps

When you’re not using an app, it keeps running in the background. This is good when you’re constantly switching between the apps. This background processing keeps the app open, so when you switch back, you don’t have to go through the entire loading process.

However, it also has a huge impact on the battery. Since the apps are running in the background, they keep on sucking the battery life. Terminating these apps from the background will help save your battery life. If you have an app that you know you won’t be using for a while, it’s best to delete it. Keep in mind that only close the apps that you won’t be using because if not, then reloading an app can be counter-productive opened soon after closing.

2. Reduce Screen Brightness

Reducing screen brightness is one of the simplest ways to preserve battery life on a used iPhone. The iPhone’s display is one of the biggest power drains, so turning down the brightness can have a big impact.

To adjust the brightness of your screen, go to Settings > Display & Brightness. From here, you can manually adjust the slider to make your screen brighter or dimmer. Or, you can enable Auto-Brightness, which will automatically adjust your screen based on the ambient light in your environment.

Additionally, you can also enable the “Reduce White Point” option to help conserve battery life. It reduces the overall brightness of a phone more than a normal brightness setting can. It will help you conserve a large amount of battery in the long run.

3. Use Power Saving Mode

When your iPhone 11 is running low on battery (or even before that), one of the best ways to save power is to enable power-saving mode. This will disable certain features and Background App Refresh to help conserve energy. To turn on power saving mode, go to Settings > Battery > Low Power Mode. You can also enable this by swiping on the top of the screen and turning on the “Low Power Saving” mode.

4. Enable Auto-Lock

If you want to preserve the battery on your used iPhone 11, one of the simplest things that you can do is to enable auto-lock. This feature will automatically lock your device after a certain period of inactivity, which can help to conserve power. 

To enable auto-lock, go to Settings > Display & Brightness > Auto-Lock. From here, you can select a time interval after which your iPhone will lock itself.

In addition to that, you can also control how long the screen remains on. No matter if you enable the screen auto-lock feature, as long as the screen goes dark after some time, the battery percentage will be saved.

5. Check for App and System Updates

Keep your used iPhone’s software up-to-date if you want to get the best experience out of your iPhone 11. Outdated apps can drain your battery and cause other performance issues, so make sure you’re regularly checking for updates.

You can check for updates to both apps and the iOS system by going to the App Store and selecting “Updates” from the menu at the bottom. For iOS updates, you’ll also need to connect your iPhone to a power source and have a Wi-Fi connection before proceeding.

6. Use Wi-Fi When Possible

You might have heard before that you should leave your Wi-Fi open when you’re not connected to Wi-Fi. This is because the Wi-Fi keeps trying to connect to a nearby cellular signal. It consumes a large amount of battery doing so.

So it’s best to use Wi-Fi whenever possible. When your phone is connected to Wi-Fi, it doesn’t have to work as hard to connect to cellular data networks, which can drain your battery. So if you’re trying to save battery life on a used iPhone, be sure to take advantage of any available Wi-Fi networks.

On the other hand, if you don’t have a connection with a Wi-Fi connection, make sure to turn it off. This way, it won’t have any battery life.

7. Don’t Use Location Services All the Time

As we’ve established before, background running tasks keep on draining battery life. The same is true for the location-based features used by apps that need to track your current location. The apps that use these features are Maps, Uber, etc. However, you don’t always need this feature enabled.

That’s why keep location services turned off when you don’t need them. Go to Settings > Privacy > Location Services and toggle the switch to “Off” on your used iPhone 11 to save battery life.

If you must use location services, make sure that the apps that are using it are only doing so when absolutely necessary. For example, an app that uses your location to provide turn-by-turn directions doesn’t need to be constantly running in the background when you’re not driving.

8. Manage Notifications

Notifications can be really helpful in keeping you up-to-date on what’s happening with your apps. However, they can also be a significant drain on your battery. Normally, during the daytime, we keep on removing the notification, but over the night, they accumulate. Constantly receiving these notifications can be a real heavy blow to the battery.

To manage your notifications, go to Settings and then tap Notifications. Here, you can see all of the apps that are currently sending you notifications and customize them to your liking. For example, you can turn off sounds or vibrations for certain apps or choose how many notifications you want to receive from each app.

Experiment with different notification settings until you find a balance that works for you and helps you save battery life.

9. Balance the Phone Temperature

Normally, the battery of the phone needs to remain in a balanced temperature environment. If it’s in either extreme cold or extreme heat, the battery will drop quickly. Cold isn’t much of an issue as heat is. Since the used iPhone 11 keeps running, it can get heated.

Additionally, if the weather is hot, it’ll only speed up the process of discharge. If your device overheats, it can damage the battery and shorten its life.

Cooling your iPhone can be done in a few simple ways:

  • Avoid using it in direct sunlight.
  • Don’t leave it in a hot car.
  • Use a case that protects against heat.
  • Take breaks when using your device for long periods of time.

If your iPhone does overheat, turn it off immediately and let it cool down in a cool, dry place.

10. Reducing Motion and Transparency Effects

Motion and transparency effects are visual effects that add depth and movement to the user interface of an iPhone. For example, when you open and close an app on your iPhone, the app icons may zoom in and out or fade in and out, which is an example of a motion effect.

Transparency effects, on the other hand, allow you to see the underlying layers of the user interface, such as the wallpaper behind the app icons. These effects are intended to add a layer of polish and sophistication to the user experience, but they can also be taxing on the battery, especially if they are used excessively.

Reducing motion and transparency effects on an iPhone can help save battery life because these features can be resource-intensive and can drain the battery faster. To reduce the motion effect, you’ll need to:

  1. Open the Settings app on your iPhone.
  2. Tap on the “General” tab.
  3. Scroll down and tap on “Accessibility.”
  4. Tap on “Reduce Motion” and toggle the switch to ON.
  5. This will disable the motion effects on your iPhone, such as the zooming and fading animations when you open and close apps.

To reduce transparency effects, follow these steps:

  1. Open the Settings app on your iPhone.
  2. Tap on the “General” tab.
  3. Scroll down and tap on “Accessibility.”
  4. Tap on “Increase Contrast” and toggle the switch to ON.
  5. This will reduce the transparency effects on your iPhone, such as the ability to see the underlying layers of the user interface.

Keep in mind that reducing or disabling motion and transparency effects can affect the overall visual appearance of your iPhone, but it can also help save battery life.
