15 Awesome Tips On How To Save iPhone Battery

Maintaining your iPhone’s battery life and lifespan is essential. It can help the resale value, in case you want to sell your device later on. Plus, it allows you to hold on to the device for years to come. In both scenarios, you save money down the line. And since the iPhone X, these devices have reached premium prices. 


What is the average lifespan of an iPhone battery? Wondering how to save iPhone battery? Is it safe to charge your iPhone overnight? When should you replace your iPhone’s battery? 

I’ll answer all these questions in this post! 

Let’s get into it.

What is the Average iPhone Battery Lifespan?

There’s no exact time frame for an iPhone’s lifespan. There are so many factors involved, and everyone’s use is different.

An iPhone’s battery lifespan brand new is measured through charge cycles. This ranges from 300 to 500 charge cycles before you notice any degrading performance in the battery.

To be clear, battery lifespan is different from a smartphone’s battery life. 

Battery lifespan – The total time the battery has to hold a charge and power your phone before it starts to degrade.

Battery life – how long you can go during the day(s) before you have to recharge it. 

How Do I Maximize Battery Life on My iPhone?

Tip #1 – Turn on Battery Percentage

What is it: Battery percentage shows the percentage of battery your iPhone has. It’s something that isn’t turned on by default on the iPhone 8 and lower. 

For iPhone X and up, they got rid of this setting under settings. You’ll find it next to your battery in the control center.

Where to find it: For iPhone 8 and older, go to Settings > Battery > Battery Percentage. 

For iPhone X and newer, swipe down from the upper right corner of the screen to display the control center. 

Why is it important: It helps see how long the battery lasts throughout the day and how much battery’s left. If you notice it draining rapidly, you can make the necessary tweaks to your phone.

Tip #2 – Turn on Low Power Mode

What is it: Low Power Mode is a function that affects the amount of power used by your iPhone. When turned on, LPM (Low Power Mode) reduces power and turns off certain features to help your battery last longer. 

Why is it important: 

The features affected by low power mode are:

  • Email fetch (Turned off)
  • “Hey Siri” (Disabled)
  • Background app refresh (Disabled)
  • Automatic downloads (Disabled)
  • Auto-Lock (Adjusted)
  • iCloud Photo Library Backups (Pauses)
  • Visual Effects and Animations (Suspended)

So when turned on, the features listed above will either be disabled, suspended, adjusted, or turned-off until LPM is turned off.

Where to find it: To turn this on, go to Settings > Battery and tap “Low Power Mode.” You can also find LPM in the control center. Doing so will add up to 2-3 hours of extra battery to your day. 

Tip #3 – Turn off Raise to Wake

What is it: Raise to Wake automatically turns on the iPhone display when it detects that it’s lifted from the resting position.

Why is it important: It’s a useful feature to check notifications from the LockScreen or to check the time. 

But always turning your display on, even when you don’t want it to, can start to drain your battery.

Where to find it: To turn this off, go to Settings > Display and Brightness > Raise to Wake.

Tip #4 – Turn off Vibrations

What is it: We all know the sometimes annoying buzz that lets us know we have a notification or a new text. That rumble in your phone is caused by a motor which draws on the battery to function.

Why is it important: It’s excellent for a phone on silent, but a potential battery sucker while your ringer is on.

Where to find it: Settings > Sounds & Haptics. Tap “Vibrate on Ring.”

Tip #5 – Manage Location Services

What is it: “Location Services uses GPS, Bluetooth, crowd-sourced Wi-Fi hotspot, and cell tower locations to determine your approximate location.” 

Rough translation, it’s what lets your iPhone know your physical location. And based on your location, provides suggestions on the nearest restaurants, stores, etc.

But Location Services also does some background functions you may not know about. 

Some of those functions are:

  • Significant Locations – Tracks and lists the locations you’ve gone to, at all times.
  • Location-Based Apple Ads – Provides customized ads in apps based on your physical location.
  • Location-Based Alerts – Allows Apple to send you location-based alerts and news.
  • Location-Based Suggestions – Recommends locations and Apps through Safari or Spotlight.

Why is it important: Apps that you download want to use your location. It makes sense for apps such as Yelp, Google Maps, and weather apps. 

If you like Apple’s recommended locations, restaurants, etc. then you might not want to turn these off. But if your concern is privacy, play around with these settings to see what works best for you.

With this setting turned on, your iPhone will use it’s networking chips in the background. This can lead to a quicker battery drain when left on.

Where to find it: Significant Locations – Settings > Privacy > System Services > Significant Locations > Tap “Significant Locations”

Location-Based Apple Ads – Settings > Privacy > System Services > Tap “Location-Based Apple Ads”

Location-Based Alerts – Settings > Privacy > System Services > Tap “Location-Based Alerts”

Location-Based Suggestions – Settings > Privacy > System Services > Tap “Location-Based Suggestions”

Tip #6 – Turn off Wi-Fi When not in Use

What is it: It’s the fastest and most reliable network to connect to for surfing the web, using social media apps, checking email, etc. 

And it can save a bit of battery over cellular signals when at a single location for an extended period of time.

Why is it important: While saving you from using up your monthly allocated data, it can drain your battery if left on when away from Wi-Fi. 

Where to find it: To turn off Wi-Fi, go to Settings > Wi-Fi > Tap “Wi-Fi.”

Tip #7 – Turn on Airplane Mode

What is it: Airplane Mode turns off all Bluetooth, Cellular, Wi-Fi, and other data connections in your iPhone by default. 

While turned on, it will make any apps that rely on your data connections unusable until turned off. 

You’ll still be able to play some games and use the camera. And in Airplane Mode, you can enable the Wi-Fi.

Why is it important: Other than traveling by plane, this mode comes in handy to save on battery when cell service is poor. 

Since this cuts off all wireless features, you don’t run the risk of your wireless connections continually searching for a connection. 

Where to find it: There are two places you can turn on this option. The first is the control center. Swipe down from the upper right corner and tap the plane icon. The second is by going to Settings and tap “Airplane Mode.”

Tip #8 – Disable Siri Suggestions

What is it: Siri Suggestions is your smart assistant recommending certain apps or actions. This can occur when you reach a specified location or happen during certain times of the day. 

For example, I tend to use Postmates often to order breakfast or lunch. After several uses, Siri tries to recommend the Postmates app to me around these times I would generally place an order. 

Why is it important: While convenient, it uses resources in the background to achieve these suggestions. When done too often, it can drain the battery over time. 

Where to find it: To turn this off, head over to Settings > Siri & Search. Under “Siri Suggestions” tap on Suggestions in Search, Suggestions in Look Up, & Suggestions on Lock Screen.

Tip #9 – Tweak Your Push & Fetch Settings

What is it: The Push function automatically downloads messages every time it hits the email server your email is hosted on.

Why is it important: Like a lot of the features on this list, this happens in the background.

And while it’s nice to have the most up to date inbox, it’s even better to have a longer-lasting battery. If this is an essential feature for you, change the duration your smartphone fetches email. 

Where to find it: To turn off Push, go to Settings > Passwords & Accounts > Fetch New Data and tap “Push.” 

To change Fetch settings, head back to Settings > Passwords & Accounts > Fetch New Data. Scroll to the “Fetch” section, and change the settings. To extend your battery life, change the fetch setting to fetch less frequently.

Tip #10 – Manage Your Notifications

What is it: Push notifications are real-time alerts from apps. They can be handy for new emails, text messages, directions, and more. It’s less useful when it comes to mobile game updates and social media updates. 

Why is it important: Each notification uses battery power to light up your HomeScreen and LockScreen to show a pop-up alert. And each notification wakes the device for five to 10 seconds. 

Notifications from games, email, Facebook, Twitter, etc. add up throughout the day. That increases the number of notifications you receive. And that increases the amount of screen-on-time your smartphone’s display uses. 

Which, you guessed it, drains the battery.

Where to find it: To manage notifications, go to Settings > Notifications. From here, adjust the notification settings like sounds, banner styles, alert locations, etc. for each app.

Tip #11 – Manage Background App Refreshing

What is it: Background App Refresh allows an app to check if there are any new updates available in the background. 

If there are, the app will download the new content in the background. When you relaunch the app, it will refresh and show the latest content.

Why is it important: This function isn’t a problem when you have a few apps. It becomes a battery drain when you have a lot of apps refreshing in the background at the same time. 

Where to find it: To manage, you can either go to Settings > General > Background App Refresh and turn this off entirely or change it to Wi-Fi. If you select Wi-Fi, you can manually turn off the apps you don’t care about.

Tip #12 – Don’t Kill Apps in Multitasking

What is it: Multitasking Is the ability to have more than one app open at once. 

Why is it important: According to Apple, there’s no benefit of quitting apps in multitasking. Quitting an app clears it out of your iPhone’s RAM. The next time you open that same app, it uses more resources and power to load everything again.

This can drain the battery fast throughout the day.

Tip #13 – Adjust Screen Brightness

What is it: Screen brightness determines how dim or bright your smartphone’s display is. Auto-Brightness adjusts the intensity of your iPhone’s screen based on the ambient lighting.

Why is it important: This is important because the dimmer the screen, the less power it consumes.

Where to find it: To find Auto-Brightness, go to Settings > Accessibility > Display & Text Size and toggle on “Auto-Brightness.”

Tip #14 – Adjust the iPhone White Point

What is it: Reduce white point helps adjust the intensity of bright colors or white spaces on display. 

Why is it important: Couple this with adjusting screen brightness and you can relieve the power used by your battery. 

Where to find it: Go to Settings > Accessibility > Display & Text Size and toggle “Reduce White Point” on. 100% lowers the intensity, while 0% increases the strength.

Tip #15 – Be Mindful of Your iPhone Cases

We’ve all gotten in the habit of throwing our phones on the charger with protective cases on. But did you know that certain style cases could damage or shorten the life of your battery? Some cases can create insulation for your iPhone, causing it to heat during its charge. 

A simple tip is to take the case off before you charge your iPhone. This will allow the phone to charge like usual without the risk of added heat that damages the battery. 

Is it Safe to Charge Your iPhone Overnight?

There’s some debate over it being safe to charge your iPhone overnight. The fear is overloading your smartphone battery and shortening its lifespan.

The short answer. Yes. It is safe to charge your phone overnight.

Smartphones have gotten smarter over the years. There’s programming in the software and built-in circuits in the battery of iPhones that will tell the phone to slow down the rate of charging as the battery fills up. Once it reaches full capacity, the battery will reject any additional charging until it needs to be charged again.

In an article posted on Digital Trends, a scientist at the Argonne Laboratory, was interviewed on the type of batteries in smartphones. In that article, the scientist, Dr. Daniel Abraham, explains that smartphones use Lithium-Ion batteries and that these batteries are capable of figuring out the charge level of a phone. When fully charged, the battery will stop charging. 

When Should You Replace Your iPhone Battery?

Now, I mentioned different ways to extend the life of your battery earlier in this post. But there comes a point where the tweaks and adjustments won’t help because your battery is too far gone. 

Some signs that signal something may be wrong with your battery: 

  • Your iPhone randomly shuts off when it shouldn’t
  • Your phone loses its charge quicker
  • Your iPhone charges slower than normal
  • It only functions when always on the charger
  • Various glitches become more frequent

These aren’t the end all be all signs, and these signs don’t always mean it’s the battery. The best way to know when to replace the battery is to check the battery health in Settings. To get there, all you need to do is go to Settings > Battery > Battery Health.

This section shows the Maximum Capacity percentage your battery can hold. 

You’ll also find Peak Performance Capability. This section shows you a message saying either “Your battery is currently supporting normal peak performance…” meaning the battery is fine.


“This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. Performance management has been applied to help prevent this from happening again…” which means your phone is being throttled to prevent future unexpected shutdowns. 

If you see that message, then it’s time to get that battery replaced.


At the end of the day, you spent a lot of money on your iPhone, so you want to get your money’s worth. If you plan on keeping your iPhone around for a long time, get used to adopting these best practices, to keep that battery healthy for as long as possible. Not every tip will work with your everyday lifestyle, so play around and find out what works best for you. But if these tips don’t show any improvements, check the battery health because it may be time to get it replaced.
