how to keep iphone 12 pro max battery health at 100

Everyone wants their iPhone battery to last longer. There are a few things you can do to save power and maximize your iPhone battery life.

Make sure that Optimized Battery Charging is enabled.

Apple’s iOS 13 update introduced a new feature designed to protect your battery by limiting the total charge until you need it. This feature is called  optimal battery charging  . This should be enabled by default, but you can double check in Settings > Battery > Battery Health.

Lithium-ion cells, like the ones used in your iPhone, degrade when they are charged capacitively. iOS 13 checks your habits and limits your charge to about 80 percent until the time you normally pick up your phone. At this point, the maximum capacity is charged.

Limiting the amount of time the battery spends at a capacity greater than 80 percent will help extend its life. It is normal for a battery to deteriorate as more charge and discharge cycles are completed, which is why eventually the batteries must be replaced.

We hope this feature will help you get a longer life out of your iPhone battery.

Identification and removal of battery consumers

If you’re curious to see where all your battery power is, go to Settings > Battery and wait for the menu at the bottom of the screen to count. Here, you can see the battery usage by each app for the last 24 hours or 10 days.

Use this list to improve your habits by identifying apps that use more than their fair share of energy. If a particular app or game is a serious drain, you can try to limit your use, use it only when connected to a charger, or even delete it and look for a replacement.

Facebook is a notorious battery drain. Deleting it may provide the biggest boost to your iPhone battery life. However, you will also likely find something better to do. An alternative that won’t completely drain your battery is to use the Facebook mobile site instead.

Limit incoming notifications

The more your phone interacts with the internet, especially over a cellular network, the more battery life will be. Every time you receive a payment request, the phone has to access and download the internet, wake up the screen, vibrate your iPhone, and maybe even make a sound.

Head to Settings > Notifications and turn off anything you don’t need. If you check Facebook or Twitter 15 times a day, you probably don’t need a whole bunch of notifications. Most social media apps allow you to adjust your in-app notification preferences and reduce their frequency.

You can even do this gradually. Tap and hold on any notification you receive until you see an ellipsis (..)) in the top-right corner of the notification box. Click this and you can quickly change the notification settings for this app. It’s easy to get used to the notifications you don’t need, but now, it’s easy to get rid of them too.

In cases like Facebook, which may be using a significant portion of your iPhone’s power, you can try to disable notifications completely. Another option, again, is to delete the Facebook app and use the web version instead, via Safari or another browser.

Do you have an iPhone OLED? Use dark mode

OLED displays create their own lighting rather than relying on backlighting. This means that their power consumption varies depending on what they display on the screen. By choosing dark colors, you can drastically reduce the amount of power your device uses.

This only works with some iPhone models that have a “Super Retina” screen, including the following:

  • iPhone X
  • iPhone XS و XS Max
  • iPhone 11 Pro and Pro Max

If you turn on dark mode under Settings > Display, you can save about 30 percent of your battery charge according to  one test  . Choose a black background for best results, since OLED models repeat black by turning off sections of the screen entirely.

You can  use dark mode on other iPhone models  , you will not see any improvement in battery life.

Use Low Power Mode to extend the remaining charge

Low Power Mode can be accessed under Settings > Battery, or you can add a custom shortcut for it in Control Center. When this feature is enabled, your device will go into power saving mode.

It does all of the following:

  • Reduces screen brightness and reduces the delay before the screen turns off
  • Disable automatic fetch for new mail
  • Disable animation effects (including those in apps) and animated wallpapers
  • Reduces background activities, such as uploading new photos to iCloud
  • It shuts down the main CPU and GPU so that iPhone runs slower

You can use this feature to your advantage if you want to extend the battery charge for a longer period. It’s perfect for those times when you’re not using your device, but want to stay connected and available for calls or texts.

Ideally, you should not rely on low power mode all the time. The fact that it reduces the clock speed of your CPU and GPU will result in a noticeable drop in performance. Required games or music creation apps may not work as they should.

Cut back on features you don’t need

Disabling features that are thirsty is a great way to improve overall battery life. While some of these things are really useful, we don’t all use our iPhones the same way.

One feature that even Apple suggests disabling if battery life is an issue is Background App Refresh, under Settings > General. This feature allows apps to activate periodically in the background to download data (such as email or news stories), and push other data (such as photos and media) to the cloud.

If you check your email manually throughout the day, you can probably get rid of new mail queries entirely. Go to Settings > Passwords & Accounts and change Fetch New Data to Manually to disable the setting completely. Even reducing the frequency to the clock should help.

Head to Settings > Bluetooth and disable it if you are not using it. You can also turn off Location Services under Settings > Privacy, but we recommend leaving this turned on, as many apps and services depend on it. While GPS has been seriously draining the battery, advancements like Apple’s motion co-processor have helped reduce its impact significantly.

You may also want to disable “Hey Siri” under Settings > Siri so that your iPhone does not constantly listen to your voice. AirDrop is another wireless file transfer service that you can disable via the Control Center, and then re-enable whenever you need it.

Your iPhone also has widgets that you can activate occasionally on the Today screen; Swipe right on the home screen to activate it. Each time you do this, any active widgets query the Internet for new data or use your location to provide relevant information, such as weather conditions. Scroll to the bottom of the list and tap Edit to remove any (or all) of them.

Reducing screen brightness can help conserve battery life, too. You can switch between the “Auto-brightness” option under Settings > Accessibility > Display and Text Size to automatically reduce brightness in dark conditions. You can also reduce the brightness periodically in Control Center.

Prefer Wi-Fi over Cellular

Wi-Fi is the most efficient way your iPhone can connect to the internet, so you should always prefer it over a cellular network. 3G and 4G (and finally 5G) networks require more power than old Wi-Fi, and will drain your battery faster.

This may prompt you to disable cellular data access for some apps and processes. You can do this under Settings > Cellular (or Settings > Mobile in some regions). Scroll to the bottom of the screen to see a list of apps that can access your cellular data. You will also see how much data they used during the Current Period.

Apps you may want to disable include:

  • Music streaming services:  Like Apple Music or Spotify.
  • Video streaming services:  such as YouTube or Netflix.
  • Apple Photos app.
  • Games that do not require an online connection.

You can also explore individual apps and reduce their reliance on cellular data without completely disabling this option.

If you are away from your Wi-Fi connection and have trouble accessing a certain app or service, you may have disabled cellular access, so always check this list.

Check and replace the battery

If your iPhone battery life is particularly poor, it might be time to replace it. This is common on devices that are more than two years old. However, if you use your phone heavily, you may go through a faster battery than that.

You can check the battery health under Settings > Battery > Battery Health. Your device will report the maximum capacity at the top of the screen. When your iPhone is brand new, that’s 100%. Below that, you should see a note about the “maximum performance capacity” of your device.

If your battery’s “max capacity” is around 70 percent, or you see a warning about “maximum performance,” it may be time to replace the battery. If your device is still under warranty or covered by AppleCare+, contact Apple to arrange a free replacement.

If your device is out of warranty, you can still take your device to Apple  and have the battery replaced  , although this is the most expensive option. If you have an iPhone X or later, it will cost you $69. Previous models cost $49.

You can take the device to a third party and replace the battery at a lower price. The problem is that you don’t know how good the replacement battery is. If you’re feeling particularly brave, you can replace the iPhone battery yourself. It’s a risky, yet cost-effective solution.

Battery life can suffer after iOS upgrade

If you recently upgraded your iPhone to a newer version of iOS, you should expect it to draw more power for a day or so before things settle down.

The new version of iOS often requires that the contents on the iPhone be re-indexed, so features like Spotlight search work properly. The Photos app may also perform an analysis on your photos to identify common objects (such as “cat” and “coffee”) so you can search for them.

This often leads to criticism of a new version of iOS for ruining iPhone battery life when, in fact, it is the last part of the upgrade process. We recommend giving it a few days of real-world use before jumping to any conclusions.

Next, tighten iPhone security and privacy

Now that you’ve done what you can to limit your battery usage, it’s a good idea to turn your attention to security and privacy. There are some basic steps that will keep your iPhone safe.

You can also perform an iPhone privacy check to make sure your data is as private as you want it to be.
